Deltamethrin and imidacloprid are commonly used insecticides for controlling sub-sucking insects in greenhouses. However, their application may cause sublethal effects on the aphid coccinellid predator (Coleoptera: Coccinellidae). Here, we study (i) the toxicity and the effect of two sublethal doses (LD and LD) of deltamethrin and imidacloprid on in a laboratory microcosm and (ii) the residual toxicity of the two insecticides in a greenhouse. The results showed that both insecticides reduced fecundity, longevity, the intrinsic rate of increase, the finite rate of increase and the net reproductive rate. However, the developmental time of the fourth instar larvae was prolonged by both insecticides at LD and LD. Deltamethrin residues were toxic 21 DAT (days after treatment) to fourth instar larvae. In contrast, imidacloprid began in the slightly harmful category (75%) 1 DAT and declined to the harmless category (18.33%) 21 DAT. These results indicate that deltamethrin and imidacloprid have potential risks to . This study provides information to guide the development of integrated pest management (IPM) strategies in greenhouses.
溴氰菊酯和吡虫啉是温室中常用的防治刺吸式口器害虫的杀虫剂。然而，它们的使用可能会对蚜虫的瓢虫捕食者（鞘翅目：瓢虫科）产生亚致死效应。在此，我们研究了（i）在实验室微观环境中，两种亚致死剂量（LD 和 LD）的溴氰菊酯和吡虫啉对[具体对象未提及]的毒性和影响，以及（ii）这两种杀虫剂在温室中的残留毒性。结果表明，两种杀虫剂均降低了[具体对象未提及]的繁殖力、寿命、内禀增长率、周限增长率和净生殖率。然而，在 LD 和 LD 剂量下，两种杀虫剂均延长了四龄幼虫的发育时间。处理后 21 天（DAT），溴氰菊酯残留对四龄幼虫具有毒性。相比之下，吡虫啉在处理后 1 天开始处于轻微有害类别（75%），并在处理后 21 天降至无害类别（18.33%）。这些结果表明，溴氰菊酯和吡虫啉对[具体对象未提及]具有潜在风险。本研究为指导温室害虫综合防治（IPM）策略的制定提供了信息。
