Abstract
Telenomus podisi Ashmead and Trissolcus euschisti (Ashmead)are sympatric parasitoids of stink bug eggs. In field experiments, T. podisi parasitized significantly more egg masses on alfalfa, Medicago sativa L., than onhackberry, Celtis occidentalis L., and T. euschisti parasitized egg masses only on hackberry. There was no significant difference in the number of host egg masses parasitized 0–1 and 3–4.2 m above the ground by T. euschisti in black cherry, Prunus serotina Ehrhart, and hackberry trees. This is one of the few examples where sympatric solitary Hymenoptera that share a host resource subdivide their environment by host plant type. We suggest that the host plant type be considered when importing scelionids for stink bug control in classical biological control programs.
