Herlihy et al.: Distribution of Cotesia rubecula and Displacement of C. glomerata 461 DISTRIBUTION OF COTESIA RUBECULA (HYMENOPTERA: BRACONIDAE) AND ITS DISPLACEMENT OF COTESIA GLOMERATA IN EASTERN NORTH AMERICA

A survey was conducted from May to Oct of 2011 of the parasitoid community of the imported cabbageworm, Pieris rapae (Lepidoptera: Pieridae), in cole crops in part of the eastern United States and southeastern Canada. The findings of our survey indicate that Cotesia rubecula (Hymenoptera: Braconidae) now occurs as far west as North Dakota and has become the dominant parasitoid of P. rapae in th...

Isolation and characterization of a Cotesia rubecula bracovirus gene expressed in the lepidopteran Pieris rapae.

Polydnaviruses are endogenous particles that are crucial for the survival of endoparasitoid wasps, providing active suppression of the immune function of the lepidopteran host in which wasp larvae develop. The Cotesia rubecula bracovirus (CrBV) is unique in that only four gene products are detected in larval host (Pieris rapae) tissues and expression of CrBV genes is transient, occurring betwee...

The effect of resource aggregation at different scales: optimal foraging behavior of Cotesia rubecula.

Resources can be aggregated both within and between patches. In this article, we examine how aggregation at these different scales influences the behavior and performance of foragers. We developed an optimal foraging model of the foraging behavior of the parasitoid wasp Cotesia rubecula parasitizing the larvae of the cabbage butterfly Pieris rapae. The optimal behavior was found using stochasti...
