摘要

蜜蜂(Apis mellifera)是农业生态系统中的主要传粉昆虫之一,因此其蜂群会接触到农用化学品,栖息地也会变得更加分散和单一。作为一种社会性昆虫,这可能会损害蜂群健康和种群增长。在此,我们对阿根廷潘帕斯农业环境中的蜂箱进行了行为学、分子学和毒理学研究,以比较不同作物管理时期蜂群的整体状态。我们的研究结果表明,在作物开花和施用杀虫剂后,觅食蜜蜂的感官和认知能力受损,大脑中与社会行为相关的代谢、免疫和神经元过程的多个基因表达也受损。这些损伤表明,居住在这些受干扰环境中的传粉昆虫群落可能会受到社会影响。据我们所知,此前还没有研究从神经生物学的角度,报道在现实的田间条件下,农业集约化对昆虫授粉者的损害效应。

Agricultural intensification impairs behavioral abilities and the expression of genes associated with social responsiveness in honeybees

The honeybee Apis mellifera is one of the main pollinators in agroecosystems, and, consequently, its colonies are exposed to agrochemicals and more fragmented and homogeneous habitats. As a social insect, this could lead to an impairment of colony health and population growth. Here, behavioral, molecular, and toxicological approaches were performed in beehives located in an agricultural setting of the Argentine pampas to compare their global state at different times of crop management. Our results show that foraging bees were impaired in their sensory and cognitive abilities and the brain’s expression of several genes related to metabolic, immune, and neuronal processes associated with social behavior after crop flowering and pesticide application. These impairments suggest potential social consequences for pollinator colonies that inhabit these disturbed environments. To our knowledge, no previous study has reported the impaired effects of agricultural intensification on insect pollinators from an integrative neurobiological perspective under realistic field conditions.
