The effects of sublethal doses of deltamethrin, a pyrethroid insecticide, and prochloraz and difenoconazole, two azole fungicides, on honey bee thermoregulation were investigated by infrared thermography of honey bees kept at 22 degrees C. Deltamethrin at doses of 0.5 and 1.5 ng/bee did not elicit any significant effect on bee thermogenesis whereas doses of 2.5 and 4.5 ng/bee caused a severe hypothermia. Similarly, prochloraz and difenoconazole did not elicit any significant effect on thermogenesis at doses of up to 850 ng/bee whereas they triggered hypothermia at 1250 ng/bee. When associated with prochloraz or difenoconazole at 850 ng/bee, deltamethrin elicited a joint hypothermia at doses that did not induce a significant effect on thermoregulation when used alone.
通过对饲养在22摄氏度环境下的蜜蜂进行红外热成像，研究了亚致死剂量的拟除虫菊酯类杀虫剂溴氰菊酯以及两种唑类杀菌剂咪鲜胺和苯醚甲环唑对蜜蜂体温调节的影响。剂量为0.5和1.5纳克/只的溴氰菊酯对蜜蜂产热没有产生任何显著影响，而剂量为2.5和4.5纳克/只时则导致严重体温过低。同样，剂量高达850纳克/只的咪鲜胺和苯醚甲环唑对产热没有产生任何显著影响，而在1250纳克/只时引发体温过低。当与850纳克/只的咪鲜胺或苯醚甲环唑联合使用时，溴氰菊酯在单独使用时对体温调节没有产生显著影响的剂量下引发了联合体温过低。
