Abstract
In this paper we formulate a model for the investigation of the infection of aphids by bacteria that protect them against parasitoid wasps. The model accounts for the possible transmission mechanisms that can originate in the environment. This includes horizontal transmission via parasitoid wasps and also short-term release of bacteria into the immediate environment after ladybird feeding. Mathematically, this corresponds to setting up a nonlinear dynamical system comprising all the relevant populations, and describing their possible mutual interactions via ordinary differential equations. A considerable effort is exerted in assessing the system's equilibria for feasibility and stability. The main theoretical result concerns the latter issue, for which the full set of the Routh-Hurwitz conditions are established analytically.
