Abstract: Toxicity of neem extract in comparison with DDVP (Dichlorvos) was determined against the housefly ( Musca domestica L). Neem leaf extract was applied at 5, 10, 20, 40 and 80 microgram/fly and DDVP was treated in 0.1, 0.2, 0.4, 0.8 and 1.6 microgram/fly doses. Lethal dose values were calculated with probit analysis and LD 50 and LD 90 values were found to be 8.4 and 169.8 ug/fly of neem extract respectively, whereas, values of 0.44 and 3.58 ug/fly of DDVP were found for LD 50 and LD 90 against house flies.
