Figure 1. Levels of intraguild predation among four species of coccinellids measured by molecular gut content analysis in soybean fields in Québec, Canada, in 2004 and 2005.

Results are expressed as the proportion of each species of intraguild prey detected in the gut of intraguild predators. Ha  =  Harmonia axyridis, C7  =  Coccinella septempunctata, Cmac  =  Coleomegilla maculata, P14  =  Propylea quatuordecimpunctata. Numbers above histogram bars represent the number of individuals tested.
