摘要:
1. Synovigenic parasitoids emerging with no or only a few mature oocytes could not rely on only capital resources, but also need to acquire income resources. Income resources in nature can either contribute to egg maturation as a food resource and/or create unpredictability in realised reproductive opportunities for synovigenic parasitoids. Therefore, we hypothesised such resources could affect life history traits and the risks of egg/time limitation in synovigenic parasitoids. 2. Using the Ovigeny Index, we investigated the effects of various ...
