Abstract

Aphids have become the paradigm for studying the effect of bacterial endosymbionts in insects. The aphid populations are an agricultural pest, and their resistance to pesticides leads to the need of other control methods, like those provided by their natural enemies (parasitoid wasps, entomopathogenic fungi, generalist predators). A number of aphid bacterial endosymbionts have been shown to confer protection against parasitism by specialized parasitoid wasps. We then investigate how the aphids become parasitized. The actual mechanism is so far not fully understood, with closed systems leading to extinction cascades. In the present work a dynamical system is formulated and its behavior is investigated.
