Abstract

Effect of Dimilin prohibiting the moulting of insects on larvae of Yponomeuta ssp. and their parasites

Field and laboratory studies made in 1974 showed that Dimilin [1-(4-chlorophenyl)-3-(2,6-difluorobenzoyl)uera] prohibited the moulting ofYponomeuta larvae and caused 100% mortality of L1-L3 at a concentrration of 0.06 ppb. Compared with this the L4 and L5 were very less susceptible.

All of the pupae growing out of L5 treated with Dimilin in the field died. But from these puape a considerable number of parasitic Hymenoptera and Diptera emerged, in the course of which the spectrum of species emerging, from treated and unterated hosts was nearly the same one.
