啶虫脒和噻虫嗪是为控制害虫而引入的杀虫剂，但它们也会影响蜜蜂等非目标昆虫。在昆虫中，已知这些烟碱类杀虫剂作用于乙酰胆碱烟碱受体，但低剂量的行为影响尚未完全了解。在实验室条件下，研究了啶虫脒和噻虫嗪对意大利蜜蜂（Apis mellifera）急性亚致死处理后行为的影响。这些药物要么口服给药，要么局部应用于胸部。口服消费后，啶虫脒增加敏感性触角刺激蔗糖溶液的剂量为1微克/蜜蜂和受损的长期保留的嗅觉学习的剂量为0.1微克/蜜蜂。啶虫脒胸部应用程序诱导在这些行为测定没有影响，但增加运动活动（0.1和0.5微克/蜜蜂）和水诱导的长鼻延伸反射（0.1，0.5，和1微克/蜜蜂）。与啶虫脒不同，噻虫嗪在所使用的条件下对蜜蜂的行为没有影响。我们的研究结果表明，一个特别脆弱的蜜蜂行为的亚致死剂量的啶虫脒。
Acetamiprid and thiamethoxam are insecticides introduced for pest control, but they can also affect non-target insects such as honeybees. In insects, these neonicotinoid insecticides are known to act on acetylcholine nicotinic receptors but the behavioral effects of low doses are not yet fully understood. The effects of acetamiprid and thiamethoxam were studied after acute sublethal treatment on the behavior of the honeybee (Apis mellifera) under controlled laboratory conditions. The drugs were either administered orally or applied topically on the thorax. After oral consumption acetamiprid increased sensitivity to antennal stimulation by sucrose solutions at doses of 1 mu g/bee and impaired long-term retention of olfactory learning at the dose of 0.1 mu g/bee. Acetamiprid thoracic application induced no effect in these behavioral assays but increased locomotor activity (0.1 and 0.5 mu g/bee) and water-induced proboscis extension reflex (0.1, 0.5, and 1 mu g/bee). Unlike acetamiprid, thiamethoxam had no effect on bees' behavior under the conditions used. Our results suggest a particular vulnerability of honeybee behavior to sublethal doses of acetamiprid.
