Current methods of broad area application of contact insecticides used in mosquito control are becoming less effective, primarily due to resistance within mosquito populations. New methods that can deliver ingestible insecticides are being investigated as a means to mitigate resistance. This study evaluated insecticide delivery through toxic sugar baits (TSB) and resulting mortality of susceptible and resistant strains of Aedes aegypti. Two Ae. aegypti strains were evaluated using a 1% boric acid TSB: the susceptible Orlando 1952 (ORL) strain and the resistant Puerto Rican (PR) strain. The TSB resulted in high mortality for both ORL and PR strain of Ae. aegypti. Average mortality of female mosquitoes given TSB was 90.8% for PR and 99.3% for ORL. Our study suggests that targeting resistant mosquitoes with ingestible insecticides through TSBs could be a viable alternative to current mosquito control strategies and should be considered when developing an integrated vector management program.

硼酸作为有毒糖诱饵对抗性埃及伊蚊的评价。

目前在蚊虫控制中广泛使用接触杀虫剂的方法正在变得不那么有效，这主要是由于蚊子种群内的抗药性。正在研究可以提供可摄入杀虫剂的新方法，以作为减轻耐药性的一种手段。本研究评估了通过有毒糖饵 (TSB) 递送杀虫剂以及由此导致的易感和抗性埃及伊蚊菌株的死亡率。两个埃。埃及菌株使用 1% 硼酸 TSB 进行评估：易感 Orlando 1952 (ORL) 菌株和抗性波多黎各 (PR) 菌株。TSB 导致Ae 的 ORL 和 PR 菌株的高死亡率。埃及人. 给予 TSB 的雌性蚊子的平均死亡率对于 PR 为 90.8%，对于 ORL 为 99.3%。我们的研究表明，通过 TSB 以可摄取的杀虫剂针对抗性蚊子可能是当前蚊子控制策略的可行替代方案，在制定综合病媒管理计划时应予以考虑。
