Learning, Host Fidelity, and the Stability of Host-Parasitoid Communities

Abstract:

Simple models of host-parasitoid interactions show that a polyphagous parasitoid tends to drive extinct all but the most fecund of its hosts. Coexistence requires a mechanism by which hosts with lower fecundity can increase when rare.We explore how recently discovered parasitoid learning behavior can contribute to species coexistence. On emergence as adults, parasitoids learn chemical cues associated with their natal host and hence are more likely to locate and to oviposit in hosts of the sam...
