Abstract:		"Males of the spined soldier bug,Podisus maculiventris (Heteroptera: Pentatomidae), produce an attractant pheromone that is exploited as a host-finding kairomone by a complex of parasitic species. The capability to catch hundreds of a generalist tachinid fly parasitoid,Euclytia flava, alive in traps baited with the pheromone ofP. maculiventris provided an opportunity to test the premise of the 'new associations' biological control concept. The hypothesis that host species newly associated with a parasitoid are maladapted relative to native-native associations was tested by givingE. flava females a choice between native and exotic stink bugs (Heteroptera: Pentatomidae). WildE. flava females preferred to oviposit on exotic pentatomid species rather than indigenous, known host species, both in field traps baited with the pheromone of a native host and in the laboratory. Data presented here demonstrate that an invader may be vulnerable to native parasitoids in one aspect of the parasitism process (acceptance), yet go unrecognized as a potential host"
