Özet
Relatively high doses of Zoecon insect grawth regulators indirectly administered' to Myzus persicae (Sulzer) resulted in one to three supernumerary larval moults.None of the compounds interfered with embryogenesis at the concentrations used, but abnormal development of the female genitalia, particularly the absence of a gonopore, was observed Parturition could not occur, and daughter larvee sometimes underwent an intramaternal moult.Supernumerary larvae not only differed from normal larvae and adults in color and body size, but malformations of antennae and hind tibiae were also observed.Alatiform larvae showed reduced ıwing development and cuticle pigmentation.The cauda underwent predictable morphological changes from the fifth to the seventh larval instar, whlch allowed identification of specific supernumerary instars.Compounds ZR-512.-515, -619, and -777 evoked qualitatively sirnilar etfects, and ZR-512 proved to be particular.yeffective when administered to young larvae.
