Mosquitoes, as disease vectors causing global morbidity and mortality through diseases like malaria, dengue, and Zika, necessitate mosquito population control methods. This study investigated the efficacy of nano-formulated insecticide-based sugar baits in controlling populations and assessed their potential non-target impact on . This laboratory-based study employed thiolated polymer-coated attractive toxic sugar bait (ATSB) nano-formulations, delivering pesticides via nano-carriers. Adult and larvae populations of insects were collected from rice and cotton fields subjected to bioassays with 0.5% and 1% concentrations of each nano-formulated and conventional insecticide within ATSB solution, alongside a control 100% attractive sugar bait (ASB). Mosquitoes interacted overnight with insecticide-treated baits, and mortality was assessed. Further observations up to 72 h were conducted for potential delayed toxic effects. Results highlighted nano-ATSB carbosulfan's effectiveness, particularly among organophosphates and pyrethroids. Among pyrethroids, nano-ATSB cypermethrin exhibited high efficacy, while Deltamethrin displayed lower mortality. Among organophosphates, nano-ATSB chlorpyrifos induced substantial mortality. The nano-formulations of insecticide were harmless against compared to their conventional form. Nano-formulations demonstrated enhanced mortality rates and prolonged efficacy against mosquitoes, having a benign impact on non-target beetles. We expect these results to aid in developing effective plant protection products suitable for IPM practices.
蚊子作为通过疟疾、登革热和寨卡等疾病导致全球发病和死亡的病媒，需要控制蚊子种群的方法。本研究调查了纳米配方杀虫剂糖饵在控制蚊子种群方面的功效，并评估了它们对[未提及的对象]的潜在非靶标影响。这项基于实验室的研究采用了硫醇化聚合物包被的诱虫毒糖饵（ATSB）纳米配方，通过纳米载体递送杀虫剂。从稻田和棉田收集昆虫的成虫和幼虫种群，用0.5%和1%浓度的每种纳米配方杀虫剂和传统杀虫剂在ATSB溶液中进行生物测定，同时设置对照100%诱虫糖饵（ASB）。蚊子与经杀虫剂处理的诱饵接触过夜，评估死亡率。对潜在的延迟毒性作用进行了长达72小时的进一步观察。结果突出了纳米ATSB克百威的有效性，尤其是在有机磷和拟除虫菊酯中。在拟除虫菊酯中，纳米ATSB氯氰菊酯表现出高效，而溴氰菊酯的死亡率较低。在有机磷中，纳米ATSB毒死蜱导致大量死亡。与传统剂型相比，杀虫剂的纳米配方对[未提及的对象]无害。纳米配方对蚊子显示出更高的死亡率和更长的药效，对非靶标甲虫有良性影响。我们期望这些结果有助于开发适合综合虫害管理实践的有效植物保护产品。
