亚致死浓度噻虫嗪对意大利蜜蜂工蜂的生存风险分析
Survival Risk Analysis Honey bee Workers (Apis mellifera L., Hymenoptera) Exposed to Sub-lethal Concentration of Thiamethoxam
摘要
Abstract
Compared with the first generation neonicotinoids,thiamethoxam is used widely for its higher efficiency,broader spectrum and lower toxicity to mammalian.However,there are no reports on the sublethal effects of thiamethoxam on the honey bees Apis mellifera L.,especially on the survival of the workers.Here we assessed the acute oral toxicities of thiamethoxam to the newly emerged bees (1 d),nurses (7 d) and foragers (22 d).Also,the survival risk of exposure to three sub-lethal concentrations (LC5,LC15 and LC25) ofthiamethoxam on different ages of workers was investigated.The results showed that the LC50 for the newly emerged bees,nurses and foragers were 248.13,64.18 and 44.20 ng/g,respectively.No significant differences in lifespan of the newly emerged bees and the foragers were detected between the control,LC5 and LC15 treatments,while LC25 treatment reduced lifespan by 19.0 d.For the nurses,the LC5 treatment didn't shorten bees' lifespan,but the LC15 and LC25 treatments reduced longevity by 9.2 and 15.0 d,respectively.For the foragers,there were no significant differences among the lifespan of the LC5,LC15 treatments and the control,while the LC25 treatment shortened lifespan by 10.9 d.These results indicate that the extensive application of thiamethoxam has great potential threat on longevity of the honey bees.More attention to monitor the field residual of thiamethoxam and assess the risk of thiamethoxam on honey bees in semi-field and field context is needed.关键词
