Feeding guild of non-host community members affects host-foraging efficiency of a parasitic wasp.

abstract：:Although many species face numerous predators in nature, the combined impact of multiple predators on the inducible defenses of prey has rarely been studied. Prey may respond with an intermediate phenotype that balances the risk from several sources or may simply respond to the most dangerous predator. I examined the ...
