Abstract

The toxicity and residual effect of a topically applied crude extract of neem (N-9) and a pyrethroid (Coopex) against second-instar larvae of Musca domestica L. (Holland strain) was studied and compared. Toxic and residual studies revealed that Coopex (permethrin + bioallethrin) was more toxic and persistent than N-9. LD_{50} 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.
