Intraguild predation between an introduced lady beetle, Harmonia axyridis (Coleoptera : Coccinellidae), and a native lady beetle, Coleomegilla maculata (Coleoptera : Coccinellidae)
Journal of the Kansas Entomological Society 71 (2), 159-163
Abstract: The introduction of the multicolored Asian lady beetle, Harmonia axyridis Pallas (Coleoptera: Coccinellidae), to the United States has led to its interaction with native coccinellid species. Harmonia axyridis adults and larvae co-occur temporally and spatially with adults and larvae of the native species, Coleomegilla maculata (DeGeer), which is the most abundant coccinellid species on sweet corn in Kentucky. We tested the capability of H. axyridis to develop on a diet of only C. maculata eggs and the propensity for either species to prey upon the other. We found that H. axyridis larvae can complete development on a diet of only C. maculata eggs and that predation between H. axyridis and C. maculata larvae usually results in H. axyridis eating C. maculata.
