新烟碱类杀虫剂啶虫脒在农业生产中广泛用于害虫防治。然而，人们对啶虫脒对非靶标传粉昆虫觅食行为的影响知之甚少。本研究旨在调查亚致死剂量的啶虫脒在自然蜂群条件下对蜜蜂（Apis mellifera L.）寿命和觅食行为的影响。每种处理的新羽化工蜂分别在胸部接受一滴1.5微升的啶虫脒溶液（含0、0.5、1和2微克/只啶虫脒，用水稀释）。使用射频识别（RFID）系统对2日龄至死亡的蜜蜂的觅食行为进行监测，包括蜜蜂首次出巢觅食的年龄、轮休状态以及出巢觅食次数。我们发现，2微克/只的啶虫脒显著缩短了工蜂的寿命，诱导其早熟觅食活动，影响轮休状态并减少出巢觅食次数。工蜂的异常行为可能与寿命缩短有关。这项工作可能为新烟碱类杀虫剂加速蜂群衰竭提供新的视角。（C）2020爱思唯尔有限公司。保留所有权利。
The neonicotinoid insecticide acetamiprid is applied widely for pest control in agriculture production. However, little is known about the effects of acetamiprid on the foraging behavior of nontarget pollinators. This study aims to investigate effects of sublethal acetamiprid doses on lifespans and foraging behaviors of honey bees (Apis mellifera L.) under natural swarm conditions. Newly emerged worker bees of each treatment received a drop of 1.5 mu L acetamiprid solution (containing 0, 0.5, 1, and 2 mu g/bee acetamiprid, diluted by water) on the thorax respectively. Bees from 2-day-old to deadline were monitored on foraging behaviors involving the age of bee for first foraging flights, rotating day-off status and the number of foraging flights using the radio frequency identification (RFID) system. We found that acetamiprid at 2 mu g/bee significantly reduced the lifespan, induced precocious foraging activity, influenced the rotating day-off status and decreased foraging flights of worker bees. The abnormal behaviors of worker bees may be associated with a decline in lifespan. This work may provide a new perspective into the neonicotinoids that accelerate the colony failure.
