Normally such plugs are secreted by the male, to stymie subsequent suitors.
通常情况下,这种粘液由雄性分泌,以此阻断其它狂蜂浪碟的追求欲念。
In spiders, though, the female sometimes assists the process.
但就蜘蛛而言,雌性蜘蛛有时也会协助这个过程。
At first sight, that is odd.
乍看上去,这是种奇怪的现象。
It is always in a male s interest to try to stop a female mating again.
试图阻止雌性蜘蛛再次交配通常是对雄性蜘蛛有利的事情。
Contrariwise, that female might come across a better male and thus wish to be rid of the firstlot of sperm.
但反过来看,雌性蜘蛛也可能会遇到更好的雄性伴侣,因此就会打算抛弃前夫的精液。
After studying this phenomenon for several years, Anita Aisenberg of the Clemente EstableInstitute of Biological Research in Uruguay has concluded that females are able to assess amale s quality during mating and that they assist plug formation only when a mate passesmuster and they thus wish to give his sperm priority.
乌拉圭Clemente Estable生物研究所的Anita Aisenberg对此现象潜心研究几年后得出结论,雌性蜘蛛在交配过程中能够评估雄性蜘蛛的质素,只有被雌性蜘蛛认可了的雄性蜘蛛才可能协助他封堵自己的生殖管道并优先采用其精液受孕。
