The present sbitly aimed to evaluate the potency of some different groups of insecticides, Synthetic pyrethrolds (esfeniralerate, fenpropathrin and lambda cyhaiothfin), Orgloophosphorus compound: (chlorPyriTOS), and Carbamale (thiodicarb) against eggs, newly hatched larvae and moths (males& females) of the pink bollworm, Pectinophore gossypeetta (Saund.), in addition to antimoulting compound (tebufenozide) against the newsy hatched larvae. The rest could be summarized as follows: a- Fno stoat: Dipping technique was used in treating 1,2,3&4 days old eggs. Fenpropathrin gave the highest effect on I,2&3 days old eggs-Whereas, chippyrifos gave the highest effect on 4 days old eggs compared with the other compounds. b-Newlylan: Residual film technique was used. Fenpropathrin was the Most potent compound than the other insecticides. c-Muhnoels: Residual film technique was used. Fenpropathrin was the most effective than the other tested Insecticides. The adult male and female moths 1-day old age of the pink bollworm were treated as TdxT9., TeXUg, UeXT2 and USXU2 and determined the number of spermatophores in each female (mating frequency) and mating ability percentage after 24, 72 hours and after females death. The results showed that: Fenpropathrin followed by esfenvalerate and lambda cyhalothrin had the highly reduction of the number of spermatophore (mating frequency) and mating ability percentage In all treatments (Tdkrg, TellU2 and UdX1-9) after 24, 72 hours and after lanais moths death. While, dilorpyrifcs and thiodicarb gave the least number of spennatophores compared with the pyrethrokl Compounds.
