我们研究了女性的交配选择隐纹瓢虫Mulsant（鞘翅目：瓢虫科）时，暴露于一个男性，她曾与一个新的男性，她从来没有遇到过交配。首次交配后，大多数雌性选择与同一雄性再次交配，并且与熟悉的雄性交配的交配潜伏期比新的雄性短。然后，我们允许雌性交配一次，与相同的雄性交配5次，或与不同的雄性交配5次，以评估不同的交配模式如何影响雌性的繁殖性能和后代适应度。与同一雄虫或不同雄虫交配5×可提高雌虫产卵量，但对孵化率或后代适合度无影响。我们的研究结果表明，女性C. montrouzieri能够区分熟悉和不熟悉的男性，并喜欢与前者交配。此外，多次交配似乎为雌性C提供了物质利益。montrouzieri特别是通过增加繁殖力。
We examined the female mating choice of Cryptolaemus montrouzieri Mulsant (Coleoptera: Coccinellidae) when exposed to a male with which she had mated before vs. a novel male which she never encountered. After first mating, most females chose to remate with the same male and showed a shorter mating latency period to copulation with the familiar male as compared to a new male. Then, we allowed a female to mate once, 5× with the same, or 5× with different males to evaluate how different mating patterns influence the females’ reproductive performance and offspring fitness. Mating 5× with the same male or different males improved female egg production, but had no effect on hatching rate or offspring fitness. Our findings suggest that female C. montrouzieri are able to distinguish between familiar and unfamiliar males and prefer to mate with the former. Further, multiple mating appears to offer material benefits to female C. montrouzieri specifically by increasing fecundity.
