ABSTRACT
Beta-cyfluthrin (OMS 3051), a new synthetic pyrethroid and one of the stereoisomers of cyfluthrin, was studied for insecticidal activity against eight mosquito species. Its larvicidal activity with LC50 values of 5.62 x 10(-5) and 1.19 x 10(-4) mg/l respectively for Culex quinquefasciatus and Aedes aegypti was comparable with that of deltamethrin. This pyrethroid was more effective against the larvae of Armigeres subalbatus (LC50 - 7.76 x 10(-7)) and the adults of Anopheles culicifacies LT50 - 27.76 min at 2.0 mu/cm2) than the other species tested. Residual efficacy at 50 mg(ai)/m2 was more persistent (for 14-25 weeks) on thatch and asbestos among the four treated surfaces. This compound also elicited oviposition deterrent activity at 0.001 mg/l against Cx.quinquefasciatus. beta-cyfluthrin is a good insecticide for mosquito control. However, care should be exercised while using it as a larvicide in breeding habitats considering its toxicity to fish.
