Abstract
- The invasive brown marmorated stink bug, Halyomorpha halys, is an economically important pest of fruit and vegetable crops. It is also a nuisance pest overwintering in large numbers in man-made structures. In its native range, natural biological control plays a key role in regulating this pest. The egg parasitoid Trissolcus japonicus is a dominant natural enemy showing high parasitism rates on H. halys eggs. Adventive populations of T. japonicus have been reported from North America and several European countries with successful establishment within the new distribution areas of H. halys. The object of this study was to monitor H. halys egg masses to assess the distribution and establishment of T. japonicus. In Germany, T. japonicus was first reported in 2020 at three sites in Baden-Wuerttemberg. Since then, additional locations have been confirmed in Hesse, Rhineland-Palatinate, Bavaria, and North Rhine-Westphalia. Thus, T. japonicus has been able to successfully overwinter, reproduce, and spread within H. halys' distribution range in Baden-Wuerttemberg. Here, the current status of presence and establishment of T. japonicus in Germany is reported. [ABSTRACT FROM AUTHOR]
