Knowledge about the effects of pesticides on biological control agents is required in order to successfully implement integrated pest management programs. The predatory mite Amblyseius swirskii Athias-Henriot has been used to control thrips, whiteflies, and broad mites in vegetable production; however, effects of fenpyroximate, an acaricide and insecticide used in vegetable crops, on A. swirskii have not been evaluated. The effect of four residual concentrations of fenpyroximate on A. swirskii females was measured under laboratory conditions including its effect on their fecundity and larval survival. Fresh residues of fenpyroximate were significantly toxic to adult females and larvae. Mortality increased and fecundity decreased as the concentration (0.026-0.208 ml/50 ml of water) and time after treatment (24-120 h) increased. Fifty percent of the larvae survived on the two lower concentrations (0.026 and 0.052 ml/50 ml of water) after 120 h.
为了成功实施病虫害综合防治计划，需要了解农药对生物防治剂的影响。捕食螨斯氏钝绥螨已被用于控制蔬菜生产中的蓟马、粉虱和侧多食跗线螨；然而，用于蔬菜作物的杀螨剂和杀虫剂唑螨酯对斯氏钝绥螨的影响尚未得到评估。在实验室条件下，测定了唑螨酯的四种残留浓度对斯氏钝绥螨雌螨的影响，包括对其繁殖力和幼虫存活率的影响。唑螨酯的新鲜残留对成年雌螨和幼虫具有显著毒性。随着浓度（0.026 - 0.208毫升/50毫升水）和处理后时间（24 - 120小时）的增加，死亡率上升，繁殖力下降。120小时后，在两种较低浓度（0.026和0.052毫升/50毫升水）下，50%的幼虫存活。
