Possible coexistence of native and exotic parasitoids and their impact on control of Halyomorpha halys

Introduction of exotic natural enemies for biological control of invasive pests may disrupt existing ecological interactions

Abstract

Introduction of exotic natural enemies for biological control of invasive pests may disrupt existing ecological interactions, which may influence the outcome of biological control introductions. The interactions between Asian egg parasitoids, proposed as classical biological control agents of the highly polyphagous invasive pest Halyomorpha halys (Sta°l), and parasitoids native to the introduced area are largely unknown. Therefore, adult and larval interspecific competition between the exotic Trissolcus japonicus (Ashmead) and the European Anastatus bifasciatus (Geoffroy) was assessed.
