文摘

Weevils show 3 main behaviors: fleeing, inspection of different seed types and mating. Competition (insect density) for resources alters behavioral patterns. Increasing competition diminishes inspecting behavior (on both tested host species). High competition lowers the number of eggs on P. vulgaris and increases on chickpea. High competition promotes fleeing and egg-dumping.
