摘要

蜜蜂利用梳理来抵御破坏性寄生虫 Varroa destructor Anderson 和 Trueman。我们使用螨虫死亡率和螨虫危害相结合的方法,观察了先前选择的高梳理行为和低梳理行为蜂群中蜜蜂个体的梳理反应。我们的目的是深入了解梳理行为的特定方面,以比较高梳理度的蜜蜂是否能区分标准化刺激物(粉笔灰)和活的瓦罗阿螨刺激物,以及高梳理度蜂群的蜜蜂是否比低梳理度蜂群的蜜蜂对不同身体区域具有更高的敏感性。我们假设,在身体的不同区域,高梳理度蜂群的蜜蜂比低梳理度蜂群的蜜蜂对这两种刺激更敏感,而且蜜蜂对瓦氏螨的反应比对标准化刺激物(粉笔灰)的反应更大。与假刺激对照组相比,当在头部或胸部施加任一刺激时,高梳理度蜂群的蜜蜂会做出更长时间的强烈梳理反应,而低梳理度蜂群的蜜蜂在刺激和假刺激之间没有差异。此外,来自高螨害率蜂群的高梳理度蜜蜂比中等螨害率的高梳理度蜂群对瓦氏螨表现出更大的梳理度。这项研究提供了新的见解,说明尽管标准化刺激物(粉笔灰)可用于评估蜜蜂个体梳理实验中的一般梳理能力,但它不能捕捉到与 Varroa 刺激物相同的反应范围。因此,在梳理试验中继续使用瓦氏螨应有助于选择对瓦氏螨更精确敏感的蜂群。

Heightened sensitivity in high-grooming honey bees (Hymenoptera: Apidae).

Honey bees use grooming to defend against the devastating parasite Varroa destructor Anderson and Trueman. We observed the grooming responses of individual bees from colonies previously chosen for high- and low-grooming behavior using a combination of mite mortality and mite damage. Our aim was to gain insight into specific aspects of grooming behavior to compare if high-grooming bees could discriminate between a standardized stimulus (chalk dust) and a stimulus of live Varroa mites and if bees from high-grooming colonies had greater sensitivity across different body regions than bees from low-grooming colonies. We hypothesized that individuals from high-grooming colonies would be more sensitive to both stimuli than bees from low-grooming colonies across different body regions and that bees would have a greater response to Varroa than a standardized irritant (chalk dust). Individuals from high-grooming colonies responded with longer bouts of intense grooming when either stimulus was applied to the head or thorax, compared to sham-stimulated controls, while bees from low-grooming colonies showed no differences between stimulated and sham-stimulated bees. Further, high-grooming bees from colonies with high mite damage exhibited greater grooming to Varroa than high-grooming colonies with only moderate mite damage rates. This study provides new insights into Varroa-specific aspects of grooming, showing that although a standardized stimulus (chalk dust) may be used to assess general grooming ability in individual bee grooming assays, it does not capture the same range of responses as a stimulus of Varroa. Thus, continuing to use Varroa mites in grooming assays should help select colonies with more precise sensitivity to Varroa.

期刊介绍: The Journal of Insect Science was founded with support from the University of Arizona library in 2001 by Dr. Henry Hagedorn, who served as editor-in-chief until his death in January 2014. The Entomological Society of America was very pleased to add the Journal of Insect Science to its publishing portfolio in 2014. The fully open access journal publishes papers in all aspects of the biology of insects and other arthropods from the molecular to the ecological, and their agricultural and medical impact.
