我们比较了两种杀虫剂（吡虫啉和溴氰菊酯）在蜜蜂中的亚致死效应在半野外和实验室条件下。将含有24 μ g kg（-1）吡虫啉或500 μ g kg（-1）溴氰菊酯的糖溶液提供给设置在室外飞行笼中的群体。与吡虫啉相比，溴氰菊酯对工蜂有致死作用。污染的糖浆与吡虫啉或溴氰菊酯诱导减少的觅食活动的食物来源和活动在蜂巢入口处。在嗅觉学习辨别任务中也观察到了吡虫啉的负面影响。自由飞行的觅食者从污染的饲养员，并进行了条件化的喙延伸反应（PER）在实验室条件下的测定。与自由飞行的蜜蜂一样，在PER程序中未发现溴氰菊酯对受限制个体的学习表现产生影响，而在半野外和实验室条件下发现吡虫啉的显著影响。(C)2003年爱思唯尔公司All rights reserved.
We have compared the sublethal effects of two insecticides in the honeybee (imidacloprid and deltamethrin) in both semi-field and laboratory conditions. A sugar solution containing 24 mug kg(-1) of imidacloprid or 500 mug kg(-1) of deltamethrin was offered to a colony set in an outdoor flight cage. In contrast to imidacloprid, deltamethrin had lethal effect on workers bees. The contamination of syrup with imidacloprid or deltamethrin induced a decrease in both the foraging activity on the food source and activity at the hive entrance. Negative effects of imidacloprid were also observed in an olfactory learnt discrimination task. Free-flying foragers were taken from the contaminated feeder and subjected to a conditioned proboscis extension response (PER) assay under laboratory conditions. As with free-flying bees, no impact of deltamethrin was found on the learning performances of restrained individuals in the PER procedure, whilst significant effects were found with imidacloprid in both semi-field and laboratory conditions.
