Abstract The tiger mosquito is a key vector of several human diseases and is considered a public health concern worldwide. The implementation of strategies aimed at maximizing mosquito control without affecting non-target insect groups is of major importance. In a field trial, we tested the efficiency of a natural pyrethrum-based vs. a synthetic pyrethroid-based insecticide in reducing tiger mosquito population and how they affect the diversity of non-target flower-visiting insects in green urban areas. Only the pyrethroid insecticide was effective in reducing mosquito abundance, although its effects disappeared nine days after application. The two adulticides did not significantly affect the diversity of flower-visiting insects, probably because of their large body size and the difference in flying and foraging activity. To effectively control mosquito populations while preventing intoxication of non-target flower-visiting insects, adulticide applications should be applied early in the morning and only on bushes and trees. Results from our small-scale applications cannot be extrapolate when larger areas are treated.

天然除虫菊和合成拟除虫菊酯对意大利帕多瓦城市绿地虎蚊、白纹伊蚊（skuse）和非目标访花昆虫的影响

摘要 虎蚊是多种人类疾病的主要传播媒介，被认为是世界范围内的公共卫生问题。实施旨在最大限度地控制蚊子而不影响非目标昆虫群体的战略非常重要。在田间试验中，我们测试了基于天然除虫菊酯的杀虫剂与基于合成拟除虫菊酯的杀虫剂在减少虎蚊种群方面的效率，以及它们如何影响绿色城市地区非目标访花昆虫的多样性。只有拟除虫菊酯杀虫剂能有效减少蚊子数量，尽管其作用在施用 9 天后消失。这两种杀成虫剂对访花昆虫的多样性没有显着影响，可能是因为它们的体型较大以及飞行和觅食活动的差异。为有效控制蚊子数量，同时防止非目标访花昆虫中毒，应在清晨施用杀成虫剂，且仅施用于灌木和树木。当处理较大的区域时，我们的小规模应用的结果不能外推。
