ATTRACTANT INSECTICIDE FOR CONTROLLING FRUIT FLY

摘要

PURPOSE:The titled insecticide, containing microcapsules containing a mixture of an attractant for fruit flies with an insecticide as a core material and a binder for adhering the microcapsules to plant bodies with a slight drift even on use in the aerial application, and having a high residual effect. CONSTITUTION:An attractant insecticide prepared by incorporating (A) flocculating type microcapsules, containing a substantially water-insoluble mixture of an attractant for fruit flies, e.g. Zeugodacus cucurbitae Coquillet, 4-(p-acetoxyphenyl)-2-butanone, with an insecticide for the fruit flies, e.g. O,O-dimethyl O-(3- methyl-4-nitrophenyl)thiophosphate, as a core material, and having a membrane material consisting essentially of gelatin and 20-150mu average particle diameter with (B) water and (D) a high polymeric emulsion or water-soluble polymer capable of forming films on evaporation of water as a binder. The insecticide may efficiently be aoplied to (1/5)-(1/15) of the area for controlling in dots, and the amount of the chemical to be applied per unit area is reduced to prevent the danger.
