Inter-Guild Influences on Intra-Guild Predation in Plant-Feeding Omnivores

摘要: Omnivorous predators that also feed on plants (omnivores) are important natural enemies of pest herbivores in many biological control programs. Bottom-up influences the plant biology these omnivores have been shown to considerable influence their interactions with target prey species. Likewise, should affect how interact other members enemy guild settings. Using community models, we show intra-guild predation (IGP) by omnivores, contrast “pure predators” do not plants, could be affected quality, and toxins. These models suggest IGP two ways: short-term affecting tendency engage IGP, long-term, both herbivore omnivore population dynamics. We review available literature effects traits (plant toxins, hairs, kairomones) omnivorous pure predator Although nature intensity conclude idiosyncratic, specific species involved.
