Technical Abstract: We employed logistical regression modeling and a group-event history model to describe the group dynamics of entomopathogenic nematodes (EPNs) in the context of risk sensitive foraging. When confronted with the decision of whether or not to invade hosts of varying quality, we argue that to invade a host that is not already infected is a “risk-prone” foraging decision. We will discuss the risks and rewards of various infection decisions by EPNs. Further, it is likely that infection decisions have great influence on the distribution of EPNs in the field.
