The biological effects of both spinosad (4.7%) and flubex (diflubenzuron DT 2%) against Aedes aegypti (Ae. aegypti (L.) mosquito larvae were assessed under laboratory conditions. The LC50 values of the spinosad and diflubenzuron were 0.22 ppm and 0.0019 ppm respectively, against Ae. aegypti larvae. The mortality rate of mosquito larvae ranged from 35- 96 % and 2-20 % for those spinosad and diflubenzuron separately. The results revealed that the spinosad formulation was highly effective against larvae comparing with flubex. Larval treatment with the IGR diflubenzuron reduced the reproductive potential of adult mosquito that emerged from these treatments by 16-84%. These results revealed that although flubex is an IGR, its larvicidal activity is better than spinosad. Further assessments and field investigation on IGRs products as insecticides alternatives should be carried out for managing Ae. aegypti mosquitoes.
