Abstract :The toxicity and residual effect of a topically applied crude extract of neem insert ignore into journalissuearticles values(N-9); and a pyrethroid insert ignore into journalissuearticles values(Coopex); against second-instar larvae of Musca domestica L. insert ignore into journalissuearticles values(Holland strain); was studied and compared. Toxic and residual studies revealed that Coopex insert ignore into journalissuearticles values(permethrin + bioallethrin); was more toxic and persistent than N-9. LD50 of Coopex 25 W.P. and N-9 was found to be 0.8 and 5.6 µg/larva, respectively; however, deformed pupae and partial emergence of adult flies were observed when only N-9 was applied.
