in synergistically effective amounts.

The present invention also provides methods for the control of insects, acarids or nematodes comprising contacting the insect, acarid or nematode or their food supply, habitat, breeding grounds or their locus with a pesticidally effective amount of mixtures of the compound I with one or more compounds II.

Moreover, the present invention also relates to a method of protecting plants from attack or infestation by insects, acarids or nematodes comprising contacting the plant, or the soil or water in which the plant is growing, with a pesticidally effective amount of a mixtures of the compound I with one or more compounds II.

This invention also provides a method for treating, controlling, preventing or protecting an animal against infestation or infection by parasites which comprises orally, topically or parenterally administering or applying to the animals a parasiticidally effective amount of a mixture of the compound I with one or more compounds II.

The invention also provides a process for the preparation of a composition for treating, controlling, preventing or protecting a warm-blooded animal or a fish against infestation

or infection by insects, acarids or nematodes which comprises a pesticidally effective amount of a mixture of the compound I with one or more compounds II.

One typical problem arising in the field of pest control lies in the need to reduce the dosage rates of the active ingredient in order to reduce or avoid unfavorable environmental or toxicological effects whilst still allowing effective pest control.

Another problem encountered concerns the need to have available pest control agents which are effective against a broad spectrum of pests.

There also exists the need for pest control agents that combine knock-down activity with prolonged control, that is, fast action with long lasting action.

Another problem encountered concerns the need to have available pest control agents which are effective against insects at various developmental stages.

Another difficulty in relation to the use of pesticides is that the repeated and exclusive application of an individual pesticidal compound leads in many cases to a rapid selection of pests which have developed natural or adapted resistance against the active compound in question. Therefore there is a need for pest control agents that help prevent or overcome resistance.

It was therefore an object of the present invention to provide pesticidal mixtures which solve the problems of reducing the dosage rate and / or enhancing the spectrum of activity and / or combining knock-down activity with prolonged control and / or to resistance management.

We have found that this object is in part or in whole achieved by the combination of active compounds defined at the outset. Moreover, we have found that simultaneous, that is joint or separate, application of compound I and one or more compounds Il or successive application of compound I and one or more compounds Il allows enhanced control of pests compared to the control rates that are possible with the individual compounds.

J) ULV solutions (UL)

10 parts by weight of the active compound(s) are dissolved in an organic solvent, for example xylene. This gives a product to be applied undiluted.

The mixture of the active compounds can be used as such, in the form of their formulations or the use forms prepared therefrom, for example in the form of directly sprayable solutions, powders, suspensions or dispersions, emulsions, oil dispersions, pastes, dustable products, materials for spreading, or granules, by means of spraying, atomizing, dusting, spreading or pouring. The use forms depend entirely on the intended purposes; it is intended to ensure in each case the finest possible distribution of the mixtures according to the invention.

Aqueous use forms can be prepared from emulsion concentrates, pastes or wettable powders (sprayable powders, oil dispersions) by adding water. To prepare emulsions, pastes or oil dispersions, the substances, as such or dissolved in an oil or solvent, can be homogenized in water by means of a wetter, tackifier, dispersant or emulsifier. Alternatively, it is possible to prepare concentrates composed of mixtures, wetter, tackifier, dispersant or emulsifier and, if appropriate, solvent or oil, and such concentrates are suitable for dilution with water.

The concentrations of the mixtures of the active compounds in the ready-to-use preparations can be varied within relatively wide ranges. In general, they are from 0,0001 to 10%, preferably from 0,01 to 1 %.

The mixtures of the active compounds may also be used successfully in the ultra-low- volume process (ULV), it being possible to apply formulations comprising over 95% by weight of active compound, or even to apply the mixtures of the active compound without additives.

Compositions of this invention may also contain other active ingredients, for example other pesticides, insecticides, herbicides, fertilizers such as ammonium nitrate, urea, potash, and superphosphate, phytotoxicants and plant growth regulators, safeners and nematicides. These additional ingredients may be used sequentially or in combination with the above-described compositions, if appropriate also added only immediately prior to use (tank mix). These agents can be admixed with the mixtures according to

the invention in a weight ratio of 1 :10 to 10:1. For example, the plant(s) may be sprayed with a composition of this invention either before or after being treated with other active ingredients.

The mixtures and methods according to the invention are particularly useful for the control of pests. The inventive mixtures are suitable for efficiently controlling insects, acarids and nematodes. They can be applied to any and all developmental stages, such as egg, larva, pupa, and adult.

The pests may be controlled by contacting the target pest, its food supply, habitat, breeding ground or its locus with a pesticidally effective amount of the inventive mixtures or of compositions comprising the mixtures.

" Locus" means a plant, seed, soil, area, material or environment in which a pest is growing or may grow.

In general, " pesticidally effective amount" means the amount of the inventive mixtures or of compositions comprising the mixtures needed to achieve an observable effect on growth, including the effects of necrosis, death, retardation, prevention, and removal, destruction, or otherwise diminishing the occurrence and activity of the target organism. The pesticidally effective amount can vary for the various mixtures / compositions used in the invention. A pesticidally effective amount of the mixtures / compositions will also vary according to the prevailing conditions such as desired pesticidal effect and duration, weather, target species, locus, mode of application, and the like.

The inventive mixtures or compositions of these mixtures can also be employed for protecting plants from attack or infestation by insects, acarids or nematodes comprising contacting a plant, or soil or water in which the plant is growing.

In the context of the present invention, the term plant refers to an entire plant, a part of the plant or the propagation material of the plant, such as the seed, the seed piece, the transplant, the seedling, or the cutting.

Plants which can be treated with the inventive mixtures include all genetically modified plants or transgenic plants, e.g. crops which tolerate the action of herbicides or fungicides or insecticides owing to breeding, including genetic engineering methods, or plants which have modified characteristics in comparison with existing plants, which can be generated for example by traditional breeding methods and/or the generation of mutants, or by recombinant procedures.

Some of the inventive mixtures have systemic action and can therefore be used for the protection of the plant shoot against foliar pests as well as for the treatment of the seed and roots against soil pests. The term seed treatment comprises all suitable seed treatment techniques known in the art, such as seed dressing, seed coating, seed dust- ing, seed soaking and seed pelleting.

The compounds I and the one or more compound(s) Il can be applied simultaneously, that is jointly or separately, or in succession, the sequence, in the case of separate application, generally not having any effect on the result of the control measures.

The compounds I and the one or more compound(s) Il are usually applied in a weight ratio of from 500:1 to 1 :6000, preferably from 20:1 to 1 :50, especially from 10:1 to 1 :10, in particular from 5:1 to 1 :20, very particularly between 5:1 to 1 :5, particularly preferabyl between 2:1 and 1 :2, also preferably between 4:1 and 2:1 , mainly in the ratio of 1 : 1 , or 5:1 , or 5:2, or 5:3, or 5:4, or 4:1 , or 4:2, or 4:3, or 3:1 , or 2:1 , or 1 :5, or 2:5, or 3:5, or 4:5, or 1 :4, or 2:4, or 3:4, or 1 :3, or 2:3, or 1 :2, or 1 :600, or 1 :300, or 1 :150, or 1 :35, or 2:35, or 4:35, or 1 :75, or 2:75, or 3:75, or 4:75, or 1 : 6000, or 1 : 3000, or 1 :1500, or 1 :350, or 2:350, or 3:350, or 4:350, or 1 :750, or 2:750, or 3:750, or 4:750.

Depending on the desired effect, the application rates of the mixtures according to the invention are from 5 g/ha to 2000 g/ha, preferably from 50 to 1500 g/ha, in particular from 50 to 750 g/ha.

The inventive mixtures are also suitable for the protection of the seed and the seed- lings' roots and shoots, against soil pests.

Conventional seed treatment formulations include for example flowable concentrates FS, solutions LS, powders for dry treatment DS, water dispersible powders WS or granules for slurry treatment, water soluble powders SS and emulsion ES. Application to the seeds is carried out before sowing, either directly on the seeds or after having pregerminated the latter, at sowing or after sowing. Preferred are FS formulations.

In the treatment of seed, the application rates of the inventive mixture are generally from 0.1 to 10 kg per 100 kg of seed. The separate or joint application of the com- pounds I and Il or of the mixtures of the compounds I and Il is carried out by spraying or dusting the seeds, the seedlings, the plants or the soils before or after sowing of the plants or before or after emergence of the plants.

The invention also relates to the propagation products of plants, and especially the seed comprising, that is, coated with and/or containing, a mixture as defined above or a

composition containing the mixture of two or more active ingredients or a mixture of two or more compositions each providing one of the active ingredients. The seed comprises the inventive mixtures in an amount of from 0.1 g to 10 kg per 100 kg, preferably from 1 g to 5 kg per 100 kg, most preferably from 1 g to 2.5 kg per 100 kg of seed.

The inventive mixtures are effective through both contact (via soil, glass, wall, bed net, carpet, plant parts or animal parts), and ingestion (bait, or plant part) and through trophallaxis and transfer.

Preferred application methods are into water bodies, via soil, cracks and crevices, pastures, manure piles, sewers, into water, on floor, wall, or by perimeter spray application and bait.

According to a preferred embodiment of the invention, the inventive mixtures are em- ployed via soil application. Soil application is especially favorable for use against ants, termites, flies, crickets, grubs, root weevils, root beetles or nematodes.

According to another preferred embodiment of the invention, for use against non crop pests such as ants, termites, wasps, flies, mosquitoes, crickets, locusts, or cock- roaches the inventive mixtures are prepared into a bait preparation.

The bait can be a liquid, a solid or a semisolid preparation (e.g. a gel). The bait employed in the composition is a product which is sufficiently attractive to incite insects such as ants, termites, wasps, flies, mosquitoes, crickets etc. or cockroaches to eat it. This attractant may be chosen from feeding stimulants or para and / or sex phero- mones. Suitable feeding stimulants are chosen, for example, from animal and/or plant proteins (meat-, fish- or blood meal, insect parts, crickets powder, egg yolk), from fats and oils of animal and/or plant origin, or mono-, oligo- or polyorganosaccharides, especially from sucrose, lactose, fructose, dextrose, glucose, starch, pectin or even molas- ses or honey, or from salts such as ammonium sulfate, ammonium carbonate or ammonium acetate. Fresh or decaying parts of fruits, crops, plants, animals, insects or specific parts thereof can also serve as a feeding stimulant. Pheromones are known to be more insect specific. Specific pheromones are described in the literature and are known to those skilled in the art.

Formulations of the inventive mixtures as aerosols (e.g in spray cans), oil sprays or pump sprays are highly suitable for the non-professional user for controlling pests such as flies, fleas, ticks, mosquitoes, locusts or cockroaches. Aerosol recipes are preferably composed of the active mixture, solvents such as lower alcohols (e.g. methanol, etha- nol, propanol, butanol), ketones (e.g. acetone, methyl ethyl ketone), paraffin hydrocar-

bons (e.g. kerosenes) having boiling ranges of approximately 50 to 250 °C, dimethyl- formamide, N-methylpyrrolidone, dimethyl sulphoxide, aromatic hydrocarbons such as toluene, xylene, water, furthermore auxiliaries such as emulsifiers such as sorbitol monooleate, oleyl ethoxylate having 3-7 mol of ethylene oxide, fatty alcohol ethoxylate, perfume oils such as ethereal oils, esters of medium fatty acids with lower alcohols, aromatic carbonyl compounds, if appropriate stabilizers such as sodium benzoate, amphoteric surfactants, lower epoxides, triethyl orthoformate and, if required, propellants such as propane, butane, nitrogen, compressed air, dimethyl ether, carbon dioxide, nitrous oxide, or mixtures of these gases.

The oil spray formulations differ from the aerosol recipes in that no propellants are used.

The inventive mixtures and their respective compositions can also be used in mosquito coils and fumigating coils, smoke cartridges, vaporizer plates, long-term vaporizers, or other heat-independent vaporizer systems.

Methods to control infectious diseases transmitted by insects (e.g. malaria, dengue and yellow fever, lymphatic filariasis, and leishmaniasis) with the inventive mixtures and their respective compositions also comprise treating surfaces of huts and houses, air spraying and impregnation of curtains, tents, clothing items, bed nets, tsetse-fly trap or the like, lnsecticidal compositions for application to fibers, fabric, knitgoods, nonwov- ens, netting material or foils and tarpaulins preferably comprise a mixture including the insecticide, optionally a repellent and at least one binder.

The inventive mixtures and the compositions comprising them can be used for protecting wooden materials such as trees, board fences, sleepers, etc. and buildings such as houses, outhouses, factories, but also construction materials, furniture, leathers, fibers, vinyl articles, electric wires and cables etc. from ants and/or termites, and for control- ling ants and termites from doing harm to crops or human being (e.g. when the pests invade into houses and public facilities). The inventive mixtures are applied not only to the surrounding soil surface or into the under-floor soil in order to protect wooden materials but it can also be applied to lumbered articles such as surfaces of the under-floor concrete, alcove posts, beams, plywoods, furniture, etc., wooden articles such as parti- cle boards, half boards, etc. and vinyl articles such as coated electric wires, vinyl sheets, heat insulating material such as styrene foams, etc. In case of application against ants doing harm to crops or human beings, the ant control composition of the present invention is directly applied to the nest of the ants or to its surrounding or via bait contact. The compounds or compositions of the inventive mixtures can also be applied preventively to places at which occurrence of the pests is expected.

In the case of soil treatment or of application to the pests dwelling place or nest, the quantity of the mixture of the active ingredients ranges from 0.0001 to 500 g per 100 m ² , preferably from 0.001 to 20 g per 100 m ² .

Customary application rates in the protection of materials are, for example, from 0.01 g to 1000 g of the mixture of the active compounds per m ² treated material, desirably from 0.1 g to 50 g per m ² .

lnsecticidal compositions for use in the impregnation of materials typically contain from 0.001 to 95 weight %, preferably from 0.1 to 45 weight %, and more preferably from 1 to 25 weight % of the mixture of the active ingredients.

For use in bait compositions, the typical content of the mixture of active ingredients is from 0.0001 weight % to 15 weight %, desirably from 0.001 weight % to 5% weight % of active compounds. The composition used may also comprise other additives such as a solvent of the active materials, a flavoring agent, a preserving agent, a dye or a bitter agent. Its attractiveness may also be enhanced by a special color, shape or texture.

For use in spray compositions, the content of the mixture of the active ingredients is from 0.001 to 80 weights %, preferably from 0.01 to 50 weight % and most preferably from 0.01 to 15 weight %.

For use in treating crop plants, the rate of application of the mixture of the active ingredients of this invention may be in the range of 0.1 g to 4000 g per hectare, desirably from 25 g to 600 g per hectare, more desirably from 50 g to 500 g per hectare.

It was also an object of the present invention to provide mixtures suitable for treating, controlling, preventing and protecting warm-blooded animals, including humans, and fish against infestation and infection by pests. Problems that may be encountered with pest control on or in animals and/or humans are similar to those described at the outset, namely the need for reduced dosage rates, and / or enhanced spectrum of activity and / or combination of knock-down activity with prolonged control and / or resistance management.

This invention also provides a method for treating, controlling, preventing and protecting warm-blooded animals, including humans, and fish against infestation and infection by pests of the orders Siphonaptera, Hymenoptera, Hemiptera, Orthoptera, Acarina, Phthiraptera, and Diptera, which comprises orally, topically or parenterally administering or applying to said animals a pesticidally effective amount of mixtures according to the invention.

The pesticidal action of the compounds and the mixtures can be demonstrated by the experiments below:

Bean aphid (aphis fabae)

The active compounds are formulated in 50:50 acetone:water and 100 ppm Kinetic® surfactant.

Nasturtium plants grown in Metro mix in the 1 ^st leaf-pair stage (variety ' Mixed Jewel' ) are infested with approximately 2-30 laboratory-reared aphids by placing infested cut plants on top of the test plants. The cut plants are removed after 24 hr. Each plant is dipped into the test solution to provide complete coverage of the foliage, stem,

protruding seed surface and surrounding cube surface and allowed to dry in the fume hood. The treated plants are kept at about 25 ⁰ C with continuous fluorescent light. Aphid mortality is determined after 3 days.

Boll weevil (Anthonomus grandis)

The active compounds are formulated in 1 :3 DMSO : water. 10 to 15 eggs are placed into microtiterplates filled with 2% agar-agar in water and 300 ppm formaline. The eggs are sprayed with 20 μl of the test solution, the plates are sealed with pierced foils and kept at 24-26°C and 75-85% humidity with a day/night cycle for 3 to 5 days. Mortality is assessed on the basis of the remaining unhatched eggs or larvae on the agar surface and/or quantity and depth of the digging channels caused by the hatched larvae. Tests are replicated 2 times.

Brown planthopper (nilaparvata lugens)

The active compounds are formulated in 50:50 acetone:water. Potted rice seedlings are sprayed with 10 ml test solution, air dried, placed in cages and inoculated with 10 adults. Percent mortality is recorded after 24, 72 and 120 hours.

Colorado Potato Beetle (Leptinotarsa decemlineata)

Potato plants are utilized for bioassays. Excised plant leaves are dipped into 1 :1 acetone/water dilutions of the active compounds. After the leaves have dried, they are individually placed onto water-moistened filter paper on the bottoms of Petri dishes. Each dish is infested with 5 - 7 larvae and covered with a lid. Each treatment dilution is replicated 4 times. Test dishes are held at approximately 27 ⁰ C and 60% humidity. Numbers of live and morbid larvae are assessed in each dish at 5 days after treatment application, and percent mortality is calculated.

Cotton aphid (aphis gossypii)

The active compounds are formulated in 50:50 acetone:water and 100 ppm Kinetic® surfactant.

Cotton plants at the cotyledon stage (one plant per pot) are infested by placing a heavily infested leaf from the main colony on top of each cotyledon. The aphids are allowed to transfer to the host plant overnight, and the leaf used to transfer the aphids is removed. The cotyledons are dipped in the test solution and allowed to dry. After 5 days, mortality counts are made.

Cowpea aphid (aphis craccivora)

The active compounds are formulated in 50:50 acetone:water. Potted cowpea plants colonized with 100 - 150 aphids of various stages are sprayed after the pest population has been recorded. Population reduction is recorded after 24, 72, and 120 hours.

Diamond back moth (plutella xylostella)

The active compounds are formulated in 50:50 acetone:water and 0.1 % (vol/vol) Al- kamuls EL 620 surfactant.

Test Procedures for root-knot nematode (Meloidogyne hapla and Meloidogyne incognita):

Tomato (variety Bonny Best) seeds are germinated in flats, then at the first true-leaf stage seedlings are transferred to planting cells. The soil in the cells is a 1 :1 mix of sandy loam and coarse sand. The transplants are maintained in the greenhouse for one week. Compounds are applied as a soil drench, 1 ml per planting cell. Each treatment is replicated three times. Later the same day, plants are inoculated with an aqueous suspension of J2 nematodes consisting of a mixed population of two root-knot nematodes, Meloidogyne hapla and M. incognita, 1 ml with 1000 J2s per cell. Plants are kept in a moist infection chamber for 1 day following inoculation, then moved to a greenhouse and bottom-watered until the root systems are harvested for evaluation.

Two weeks after inoculation, tomato root systems are harvested and the number of root-knot galls on each root system are counted.

Nematicidal activity is calculated as the percent reduction in root-knot galls as follows where:

T = The median number of root-knot galls for a treatment. SB = The median number of root-knot galls for the solvent blank control. Percent reduction in root-knot galling = ((SB - T) / SB ) ^* 100%

Eastern subterranean termites (Reticulitermes flavipes) and Formosan subterranean termites (Coptotermes formosanus)

Toxicant treatments (1.0% test compound w/w) are applied to 4.25 cm (diam.) filter papers (VWR #413, qualitative) in acetone solution. Treatment levels (% test compound) are calculated on basis of a mean weight per filter paper of 106.5 mg. Treatment solutions are adjusted to provide the quantity of toxicant (mg) required per paper in 213 ml of acetone (volume required for saturation of paper). Acetone only is applied for untreated controls. Treated papers are vented to evaporate the acetone, moistened with 0.25 ml water, and enclosed in 50x9 mm Petri dishes with tight-fit lids (3-mιm hole in side of each dish for termite entry).

Termite bioassays are conducted in 100x15 mm Petri dishes with 10 g fine sand spread in a thin layer over the bottom of each dish. An additional 2.5 g sand is piled against the side of each dish. The sand is moistened with 2.8 ml water applied to the piled sand. Water is added to dishes as needed over the course of the bioassays to maintain high moisture content. Bioassays are done with one treated filter (inside en- closure) and 30 termite workers per test dish. Each treatment level is replicated in 2 test dishes. Test dishes are maintained at about 25 ⁰ C and 85% humidity for 12 days and observed daily for mortality.

Orchid thrips (Dichromothrips corbetti)

Dichromothrips corbetti adults used for bioassay are obtained from a colony maintained continuously under laboratory conditions. For testing purposes, the test compound is diluted to a concentration of 500 ppm (wt compound: vol diluent) in a 1 :1 mixture of acetone:water, plus 0.01 % Kinetic surfactant.

Thrips potency of each compound is evaluated by using a floral-immersion technique. Plastic petri dishes are used as test arenas. All petals of individual, intact orchid flowers are dipped into treatment solution for approximately 3 seconds and allowed to dry for 2 hours. Treated flowers are placed into individual petri dishes along with 10 - 15 adult thrips. The petri dishes are then covered with lids. All test arenas are held under continuous light and a temperature of about 28 ⁰ C for duration of the assay. After 4 days, the numbers of live thrips are counted on each flower, and along inner walls of each petri dish. The level of thrips mortality is extrapolated from pre-treatment thrips numbers.

Test Methodology

1. Activity against Argentine ant, harvester ant, acrobat ant, carpenter ant, fire ant, house fly, stable fly, flesh fly, yellowfever mosquito, house mosquito, malaria mosquito, German cockroach, cat flea, and brown dog tick via glass contact

Glass vials (20 ml scintillation vials) are treated with 0.5 ml of a solution of active ingredient in acetone. Each vial is rolled uncapped for ca. 10 minutes to allow the a.i. to completely coat the vial and to allow for full drying of the acetone. Insects or ticks are placed into each vial. The vials are kept at 22 ⁰ C and are observed for treatment effects at various time intervals. Results are presented in Table I.

2. Activity against Argentine ant, acrobat ant, carpenter ant, fire ant, and eastern subterranean termite via soil contact

For ants, tests are conducted in Petri dishes. A thin layer of 1 % agar in water is dispensed into the dishes and Florida sandy soil is spread over the agar (5 g for the small dishes and 11 g for the larger dishes). The active ingredient is dissolved in acetone and dispensed over the sand. Dishes are vented to evaporate the acetone, infested with ants, and covered. A 20% honey water solution is placed in each dish. The dishes are maintained at 22 ⁰ C and observed for mortality at various time intervals.

For termites, a thin layer of 1 % agar is dispensed into Petri dishes. A thin layer of pre- treated soil is spread over the agar. For soil treatment, the active ingredient is diluted in acetone on a weight-to-weight basis and incorporated into 100 g of soil. The soil is placed in a jar and vented for 48 hours. The moisture level of the soil is brought to field capacity by adding 7 ml of water. Termite workers are introduced into each dish. A small piece of filter paper is placed into each dish after 1 day as a food source, and additional water is added as needed to maintain soil moisture. Test dishes are held at a dark incubator at 25 ⁰ C and appr. 80% relative humidity. Termites are observed daily for mortality (dead or unable to stand upright and showing only weak movement). Results are shown in Table I.

3. Activity against Argentine ant, acrobat ant, carpenter ant, fire ant, house fly, east- ern subterranean termite, Formosan subterranean termite, and German cockroach via bait

For Argentine ant, acrobat ant, and carpenter ant, tests are conducted in Petri dishes. Ants are given a water source, and then are starved of a food source for 24 hours. Baits are prepared with either 20% honey/water solutions or ground cat chow. Active ingredient in acetone is added to the bait. 0.2 ml of treated honey water solution or 150

mg of treated cat chow, placed in a cap, is added to each dish. The dishes are covered and maintained at a temperature of 22 ⁰ C. The ants are observed for mortality daily. Results are shown in Table I.

For the fire ants, corn grit is used as a bait matrix. Corn grit bait is prepared using a mixture of defatted corn grit (80%), soybean oil (19.9%), acetone, and the active ingredient (0.1 %). Petri dishes are supplied with a water source. Fire ant adults are placed into each dish. The next day, 250 mg of bait in bait containers is placed into the dishes. The ants are observed for mortality daily. Results are shown in Table I.

For house flies. Bait tests are conducted with adults aged 2-5 days post-emergence. Active ingredient in acetone is applied to a bait matrix consisting of a 1 :1 mixture of powdered milk and sugar which is then allowed to dry. Assays are conducted in jars with 250 mg of bait in a pan placed in the bottom of each jar. House flies are placed into the bait jars which are covered. The test jars are held at 22°C. Test jars are observed at 4 hours after treatment for knockdown (death plus morbidity (unable to stay upright). Results are shown in Table I.

For termites, active ingredient in acetone is applied to filter papers. % a.i. are calcu- lated on basis of the weight of the filter paper. Acetone only is applied for untreated controls. Treated papers are vented to evaporate the acetone, moistened with ml water, and placed Petri dishes with sand. Water is added during the test as needed. Bio- assays are conducted with one treated filter and ca. 30 termite workers per test dish. Test dishes are maintained at 25 ⁰ C and appr. 85% relative humidity and observed daily for mortality (dead or moribund insects) or intoxication. Dead or moribund insects are removed daily. Results are shown in Table I.

For cockroaches, plastic roach boxes with ventilated lids are used as test arenas. The top 3-4 cm of the arenas is treated with Vaseline and mineral oil to prevent roaches from escaping. Water is provided as needed. The bait is prepared using ground cat chow, and the active ingredient in acetone is incorporated on a weight- to-weight ratio. The treated chow is allowed to dry. The cockroaches are placed in the boxes and starved for 24 hours prior to bait introduction. 0.03 grams of bait per box are placed in a weigh boat. The boxes are maintained at 22 ⁰ C and observed daily for mortality of the cockroaches. Results are shown in Table I.

4. Activity against yellowfever mosquito, southern house mosquito, and malaria mosquito larvae via water treatment

Well plates are used as test arenas. The active ingredient is dissolved in acetone and diluted with water to obtain the concentrations needed. The final solutions containing

appr. 1 % acetone are placed into each well. Approximately 10 mosquito larvae (4 ^th - instars) in 1 ml water are added to each well. Larvae are fed one drop of liver powder each day. The dishes are covered and maintained at 22°C. Mortality is recorded daily and dead larvae and live or dead pupae are removed daily. At the end of the test remaining live larvae are recorded and percent mortality is calculated. Results are shown in Table I.

Each test is replicated at least 2 times.

The presence of a synergistic effect in terms of percent control, between the two mixing partners (X and Y) is calculated using the Colby equation (Colby, S. R., 1967, Calculating Synergistic and Antagonistic Responses in Herbicide Combinations, Weeds, 15, 20-22):

XY E =

Too

When the observed combined control effect is greater than the expected combined control effect (E), then the combined effect is synergistic.

The test results below show that the mixtures according to the invention show a considerable enhanced activity demonstrating synergism compared to the calculated sum of the single activities.
