Extract

Intraguild predation, a common interaction among arthropods (Polis et al. 1989), has been investigated recently in aphidophages (Rosenheim et al. 1993; Lucas et al. 1998). Sessile stages of coccinellids, gall midges, and lacewings (eggs, moulting individuals, and pupae) were shown to be highly vulnerable to intraguild predators (Lucas et al. 1998). Several defensive mechanisms have already been described for eggs of aphidophages, including chemical protection (Eisner et al. 1996), structural protection (Canard and Duelli 1984), and behavioural avoidance through the selection by females of protected oviposition sites (E. Lucas, and J. Brodeur, unpublished data).
