Classical biological control of the brown marmorated stink bug (Halyomorpha halys) in apple orchard: a success story.

ABSTRACT:

Background

The brown marmorated stink bug (BMSB), Halyomorpha halys, is an invasive pest from eastern Asia that has caused significant damage to apple orchards in Europe and the United States. To reduce pesticide reliance, a classical biological control (CBC) program, using the Asian egg parasitoid Trissolcus japonicus, was initiated in Trentino, a key apple-producing area in Italy. The CBC program involved the release of T. japonicus at selected sites with minimal chemical input from 2020 to 2023. Monitoring was conducted to assess parasitoid establishment and egg parasitization rates. Preliminary data on fruit damage were also collected to assess trends at a large territorial scale. Parasitoid efficacy was evaluated based on discovery efficiency and parasitization impact.
