Why Are Phytophagous Insects Typically Specialists?
WebThe evolution of host specialization in phytophagous insects is generally thought to involve genetic trade-offs that prevent individuals from maximizing fitness simultaneously on two or more hosts. Several hypotheses, however, have suggested that trade-offs may not be evident in experiments comparing larval performance on normal and novel hosts.
