To obtain an insecticidal and acaricidal composition having good insecticidal and acaricidal characteristics by including a dihydrofuranone derivative and a specific macrolide, an extender and/or a surfactant.
This composition is obtained by including an active compound combined formulation comprising (A) a dihydrofuranone derivative represented by formula I, (B) one or more macrolides selected from 17 kinds of compounds such as (i) a phenylhydrazine derivative represented by formula II (bifenazate), (ii) a mcrolide represented by formula III in which common name is abamectin, (iii) a naphthalenedione derivative represented by formula IV (acequinocyl) and (iv) a pyrrole derivative represented by formula V (chlorfenapyr) and (C) an extender and/or a surfactant. Although the ingredient A is a known compound and the ingredient B is a known pest controlling active compound, satisfactory effects are obtained at a low application ratio by combining the ingredients.
