Halyomorpha halys (Stål, 1855) (Hemiptera: Pentatomidae), the brown marmorated stink bug (BMSB), is an alien invasive pest that originated from South Asia (China, Japan, Taiwan, Korea) Many studies have shown that the number of invasions by pests has increased significantly in the last 5 centuries and the reason for this situation is directly related to human activities. Halyomorpha halys is considered to be a dangerous pest insect species due to economic losses in agricultural areas of the countries where it is distributed. It has been observed that the pest can have 1–2 generations per year and each egg mass contains of an average of 28 eggs and, furthermore, causes significant losses in many crops such as bean, hazelnut and pear. This study was conducted between July and August in 6 different areas and a total of 18 egg masses that were thought parasitized were collected from grape vine, tree of heaven, kiwi and hazelnut trees ) BMSB infested fields and kept in tubes to determine if they had parasitoids. Emerged parasitoids were fed with the 10% honey water solution and bred in tubes. In this study, Anastatus bifasciatus (Geoffroy) (Hymenoptera: Eupelmidae) was recorded as the first parasitoid of Halyomorpha halys in Türkiye.
