ABSTRACT Mosquito pesticides effectively control vectors of human disease but have numerous unintended consequences. These may include adversely affecting non-target species such as weed biological control agents. Acute toxicity of two mosquito pesticides, naled and permethrin, was studied on three biological control agents released against invasive weeds in south Florida. These were the biological control agent Oxyops vitiosa of melaleuca, Melaleuca quinquenervia, the agent Neomusotima conspurcatalis for Old World climbing fern, Lygodium microphyllum, and the agent Lilioceris cheni for air potato Dioscorea bulbifera. We calculated LD50 values for both pesticides on early and late instars for each herbivore species. The air potato herbivore, L. cheni was the most sensitive species tested and all three species were more sensitive to the pesticide permethrin than naled. These results indicate that even low concentrations of these products can have a detrimental effect on these weed biological control agents. The unintended consequences of mosquito adulticide applications should be considered when evaluating biological control agent impacts.

美国南佛罗里达州蚊子杀虫剂对杂草生物防治剂的急性毒性

摘要 蚊子杀虫剂有效地控制了人类疾病的传播媒介，但会产生许多意想不到的后果。这些可能包括对非目标物种（例如杂草生物控制剂）产生不利影响。在佛罗里达州南部针对侵入性杂草释放的三种生物控制剂，研究了两种蚊子杀虫剂 naled 和氯菊酯的急性毒性。这些是生物防治剂白千层、白千层的生物防治剂，旧世界攀缘蕨类植物的新木霉，小叶海棠，以及空气马铃薯薯蓣的生物防治剂Lilioceris cheni。我们计算了每个食草动物物种的早龄和晚龄农药的 LD50 值。空气马铃薯草食动物，L. cheni 是测试中最敏感的物种，所有三个物种对杀虫剂氯菊酯都比 naled 更敏感。这些结果表明，即使是低浓度的这些产品也会对这些杂草生物防治剂产生不利影响。在评估生物控制剂的影响时，应考虑使用杀蚊剂的意外后果。
