Description
Two stink bugs feed on hazelnuts in northwestern Türkiye: a native species, Palomena prasina, and an invader, Halyomorpha halys, that causes heavy crop damage. The authors survey egg masses of both bugs over three years, from 2022 to 2024, in 65 hazelnut and fruit orchards. They collect more than 15,000 eggs of the native bug and about 8,500 of the invader. Eggs are kept in the lab so that any parasitic wasps inside can emerge and be identified by shape and by DNA.
Parasitism reached 17.39 percent in the native bug but only 1.98 percent in the invader. One wasp, Trissolcus belenus, was the most common attacker of the native species and also appeared in the invader's eggs. The authors argue that native wasps already suppress the native bug well. Protecting and boosting these wasps could support greener pest control and cut insecticide use in hazelnut orchards.
