- 摘要：
- Several ecological and genetic factors affect the diet specialization of insect herbivores. The evolution of specialization may be constrained

- 摘要：
- t-specialist tradeoff exists within this group of parasitoids, and that the generalist fitness cost depends on the taxonomic breadth, rather than the numb
