Neonicotinoid pesticides harm nontarget insects, but their sublethal effects on butterflies are understudied. We exposed larvae of 3 butterfly species (Pieris rapae, Colias philodice, and Danaus plexippus) to low levels of the neonicotinoid imidacloprid in their host plants and followed individuals to adulthood. Imidacloprid altered adult body size, especially in female monarchs, but its effects varied across maternal families, highlighting the importance of considering genetic variation in ecotoxicological testing.

遗传变异影响 3 种蝴蝶对新烟碱类杀虫剂的耐受性。


新烟碱类杀虫剂会伤害非目标昆虫，但其对蝴蝶的亚致死作用尚未得到充分研究。我们将 3 种蝴蝶（菜粉蝶、绿粉蝶和斑蝶）的幼虫暴露在寄主植物中低浓度的新烟碱类吡虫啉中，并跟踪个体直至成年。吡虫啉改变了成年帝王蝶的体型，尤其是雌性帝王蝶，但其影响因母系家庭而异，凸显了在生态毒理学测试中考虑遗传变异的重要性。环境毒理学2020；39：2228–2236。 © 2020 SETAC 版权所有
