过寄生现象是寄生蜂种内竞争的一个重要例子。在这项研究中，我们发现，多寄生的Blissoxenos esakii（昆虫纲，Strepsiptera）诱导较早的成虫出现的单寄生（单寄生在主机）。过度寄生创造了条件，其中多个链翅目幼虫必须竞争宿主身体上有限的（两个）出口空间，以使其成为成虫。因此，自然选择可能会青睐缩短幼虫生长期的链翅类，这样它们就可以更早出现。因此，过寄生导致链翅虫生活史的巨大变化。
Superparasitism (multiple parasites in a single host) is one of the most significant examples of density-dependent intraspecific competition among insect parasitoids. In this study, we showed that multiple parasitism byBlissoxenos esakii(Insecta, Strepsiptera) induce earlier adult emergence than solitary parasitism (single parasite in a host). Superparasitism creates conditions wherein multiple strepsipteran larvae must compete for the limited (two) exit spaces on the host body for their emergence as adults. As a result, selection might have favored strepsipterans that shortened the period of larval growth, so that they can emerge earlier. Thus, superparasitism causes a dramatic change in the life history of strepsipteran.
