恶虫威对拟除虫菊酯抗性按蚊的药效。在实验室和田间条件下，评价了该杀虫剂在不同基质上的残留寿命。根据WHO（世界卫生组织）标准方案，在用恶虫威浸渍的不同基质上进行生物测定。使用R软件使用二项式回归模型分析数据。敌虫威对拟除虫菊酯抗性按蚊有较好的防治效果。冈比亚，并观察到其剩余寿命根据所处理的表面的高度变化。雌蚊在接触处理过的基质13周后死亡的可能性低于80%，柚木; 7周的墙壁与沙子和水泥的混合物和6周的墙壁与红粘土和红粘土和水泥的混合物。考虑到虫威在红粘土墙壁上的残留寿命，红粘土是贝宁农村地区室内滞留喷洒运动期间处理的主要基质，每年需要两轮以上的处理，才能在这些地区使用虫威实现室内滞留喷洒的长期功效。实现这种覆盖水平所需的财政和后勤资源需要非洲疟疾流行国家领导人表现出更大的政治意愿。在等待创新的疟疾控制工具的同时，贝宁必须使用替代杀虫剂或杀虫剂组合来进行杀虫剂抗药性管理。
The efficacy of bendiocarb against pyrethroid resistant An. gambiae and the residual life of this insecticide on different substrates were evaluated under laboratory and field conditions. Bioassays according to the WHO (World Health Organization) standard protocol were carried out on different substrates impregnated with bendiocarb. Data were analyzed using a binomial regression model with R software. A good efficacy of the bendiocarb against pyrethroid resistant An. gambiae and a high variation of its residual life according to the surfaces treated was observed. The probability that a female mosquito died after exposure to a treated substrate was below 80% after 13 weeks for the teak wood; 7 weeks for the wall made with a mixture of sand and cement and 6 weeks for walls made with red clay and those made with a mixture of the red clay and cement. Considering the residual life of bendiocarb on walls made with red clay, the main substrates treated during IRS campaigns in rural areas in Benin, more than 2 treatments rounds per year would be necessary to achieve a long term efficacy of IRS using bendiocarb in these areas. Financial and logistical resources required to achieve such levels of coverage need more political will from leaders of African endemic countries. While waiting for innovative malaria control tool, alternative insecticides or combinations of insecticides have to be used for insecticide resistance management in Benin.
