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.
高效氟氯氰菊酯（OMS 3051）是一种新型合成拟除虫菊酯，也是氟氯氰菊酯的立体异构体之一，已针对8种蚊虫进行了杀虫活性研究。其对致倦库蚊和埃及伊蚊的杀幼虫活性分别为LC50值5.62×10⁻⁵和1.19×10⁻⁴mg/l，与溴氰菊酯相当。这种拟除虫菊酯对骚扰阿蚊幼虫（LC50 - 7.76×10⁻⁷）和嗜人按蚊成虫（在2.0μg/cm²时LT50 - 27.76分钟）的效果比其他受试物种更好。在四个处理过的表面中，50mg（有效成分）/m²的残留药效在茅草和石棉上持续时间更长（14 - 25周）。该化合物在0.001mg/l时还对致倦库蚊产生产卵驱避活性。高效氟氯氰菊酯是一种控制蚊虫的良好杀虫剂。然而，鉴于其对鱼类的毒性，在繁殖栖息地将其用作杀幼虫剂时应谨慎使用。
