Superparasitism and its effects on the fitness of the larval parasitoid, Coccygidium luteum (Hymenoptera: Braconidae) Open
The tendency of parasitoid wasps to oviposit in a previously parasitised host (superparasitism) has long been considered detrimental to their fitness, until recent evidence showed that it may be an adaptive strategy. The solitary koinobion…
