蜂王受精囊维持精子可育性的生理基础研究进展

Research advances in the physiological basis of spermatheca of honeybee bee queen on stored sperm viability

蜜蜂是社会性群居昆虫,蜂群中通常只有1头生殖系统发育健全、具有繁殖能力的雌性个体——蜂王,保持蜂王旺盛的产卵力是蜂群繁衍和发展的重要保障。受精囊是蜂王交配后存储精子的结构,它可以维持精子可育性长达数年之久,其生理结构和功能值得深入探讨。本文综述了近年来蜜蜂受精囊结构与生殖生理、精子活力的影响因素和蜂王受精囊微环境的生理功能等领域的研究进展,旨在为蜜蜂种质资源评价、保护和利用以及害虫防治策略提供指导。

In a eusocial bee colony with a single queen,the only fertile female one who lays fertilized and unfertilized egg to breed population.A fertile queen is necessarily linked to colony fitness.The mature virgin queen only mates during a very brief period to acquire and store a lifetime supply of sperm.As sperm cannot be replenished,the polyandrous queen must keep the stored sperm viable in the spermatheca for several years.However,certain aspects of the physiological roles remain largely unclear and further studies are required to address it.This article reviewed the accumulated evidences of morphology,reproductive physiology,sperm motility factors and micro environment of spermatheca support on the sperm long term storage,to provide the systematic understanding of honeybee resources evaluation,protection and utilization,as well as the pest control strategies.
