Insecticides used in agricultural pest management pose survival risks to the stingless bees that forage on crops in tropical and subtropical regions. In the present study, we evaluated, under laboratory conditions, the acute oral toxicity of five selected insecticides (dinotefuran, imidacloprid, flupyradifurone, spirotetramat, and cyantraniliprole) to two species of neotropical stingless bees: and . At field recommended doses, dinotefuran, imidacloprid, and flupyradifurone caused the highest mortality in both bee species. These insecticides also caused the largest decrease in the survival rate when exposed to a 10-fold dilution of the field recommended doses. Notably, dinotefuran exerted a high effect even at 100-fold dilution (100% mortality). In contrast, cyantraniliprole had a low effect and spirotetramat was virtually nontoxic. These results suggest that some insecticides used to control sap-sucking insects may have a significant negative impact on the communities of stingless bees.
用于农业害虫管理的杀虫剂对在热带和亚热带地区的作物上觅食的无刺蜂构成生存风险。在本研究中，我们在实验室条件下评估了五种选定杀虫剂（呋虫胺、吡虫啉、氟吡呋喃酮、螺虫乙酯和氰虫酰胺）对两种新热带无刺蜂物种（ 和 ）的急性经口毒性。在田间推荐剂量下，呋虫胺、吡虫啉和氟吡呋喃酮在两种蜜蜂物种中导致的死亡率最高。当暴露于田间推荐剂量的10倍稀释液时，这些杀虫剂还导致存活率下降幅度最大。值得注意的是，即使在100倍稀释（100%死亡率）时，呋虫胺仍具有很高的毒性。相比之下，氰虫酰胺的毒性较低，而螺虫乙酯几乎无毒。这些结果表明，一些用于控制吸食汁液昆虫的杀虫剂可能对无刺蜂群落产生重大负面影响。
