Pollinators

传粉者

    在对秘鲁任何地区的整个蜜蜂动物群的第一次实地调查中,我们报告了总共1796只蜜蜂,属于四个科的181种或形态物种。分类学障碍很明显,只有181种中的80种可以命名。有这么高比例的不确定物种,不可能充分比较不同研究的传粉者群落,评估历史变化或分析特有模式以记录生态学,物种和属的行为和进化。需要这些信息为决策者保护栖息地以保护本地传粉者提供坚实的基础。
    In this first field survey of an entire bee fauna for any part of Peru, we report a total of 1796 bees belonging to 181 species or morphospecies in four families. The taxonomic impediment was pronounced with only 80 species of 181 that could be named. With such a high proportion of undetermined species, it is not possible to adequately compare pollinator communities across different studies, assess historical changes or analyze endemism patterns to document ecology, behavior and evolution of the species and genera. This information is required to provide a sound basis for policymakers to protect habitats for the conservation of native pollinators.

    BACKGROUND: Neonicotinoid insecticides have been the target of much scrutiny as possible causes of recent declines observed in pollinator populations. Although neonicotinoids have been implicated in honey bee pesticide incidents, there has been little examination of incident report data. Here we summarize honey bee incident report data obtained from the Canadian Pest Management Regulatory Agency (PMRA).
    RESULTS: In Canada, there were very few honey bee incidents reported in 2007-2011 and data were not collected prior to 2007. In 2012, a significant number of incidents were reported in the province of Ontario, where exposure to neonicotinoid dust during planting of corn was suspected to have caused the incident in up to 70% of cases. Most of these incidents were classified as \'minor\' by the PMRA, and only six cases were considered \'moderate\' or \'major\'. In that same year, there were over three times as many moderate or major incidents due to older non-neonicotinoid pesticides, involving numbers of hives or bees far greater than the number of moderate or major incidents suspected to be due to neonicotinoid poisoning.
    CONCLUSIONS: These data emphasize that, while exposure of honey bees to neonicotinoid-contaminated dust during corn planting needs to be mitigated, other pesticides also pose a risk.
