Abstract
The present work aim to study the effect of insecticides on certain aspects of the bionomics of Spodoptera littorolis (Boisd.). The study includes the following points :-
1- Egg Treatment :
A- Relative susceptibility of Spodopterc egg-masses to certain insecticides
According to Lc50 obtained, it was found that chlorpyrifos posses highest efficiency and showed homogenity in its effect. Chlordimeform and methomyl showed moderate ovicidal action, while leptophos
and endrin did not affect the egg-masses.
