Abstract
The exogenous a nilc hormone extract on the larvae of three lepidopterous species (Plutella xytostella Linn., spodoptera litura Fabr. and Helicoverpa armigera Linn armigerg Hubn) markedly reduced the fecundity of the emergent moths and the viability of their eggs. Partial
Sterility was transmitted to the F1 generation at ED50 dose. The development of the F1 larvae from ED10 and F2 larvae from ED50 emergent moths was completely arrested. Sterility was partially due to the incomplete differentiation of the follicular epithelium and maturation of the oocyte, reduction in the number of ovarioles and deformation of the latter.
Moths from treated larvae mated longer and as actively as did the control moths. Sperm was normally transferred to the female through the spermatophoro.
The use of Attacus JH for insect control will represent the combination of chemosterilization and the introduction of deleterious genes into a population. It is a promising tool for the pest management of the three under test insects but it warrants further assessment under field condition.
