【摘要】 昆虫两性成功交配后,雄性生殖腺分泌物使雌性昆虫的生理和行为都发生了巨大的改变。昆虫雄性生殖腺分泌物含有多种具有生物活性的分子,这些生物活性分子通过成功交配转移到雌虫生殖道后,对雌虫的生殖活动产生影响,使交配雌虫一段时间内不再交配,使已转移的精子易于在雌虫生殖道内储藏,使卵与精子完成受精过程,还可刺激雌虫产卵和卵的发育,调控排卵和产卵等生殖过程。在精子的转移过程中,雄性生殖腺分泌物中的抗菌媒介质能使雌虫的生殖导管提供友好的环境。此外,一些昆虫的雄性生殖腺分泌物还含有一些有毒的化学物质,保护已产下的卵不被天敌取食和病原体侵染。更多还原

【Abstract】 Secretions of male accessory glands contain a variety of bioactive molecules. When transferred during mating, these molecules exert wide-ranging effects on female reproductive activity. The secretions may render her unwilling or unable to remate for some time, facilitating sperm storage and ensuring that any eggs laid will be fertilized by that male’s sperm. The secretions may stimulate an increase in the number and rate of development of eggs and modulate ovulation and oviposition. Antimicrobial agents in the secretions ensure that the female reproductive tract is a hospitable environment during sperm transfer. In a few species the secretions include noxious chemicals. These are sequestered by developing eggs that are thereby protected from predators and pathogens when laid.更多还原
