In 2020 and 2021, chalcidoid parasitoids (Hymenoptera, Chalcidoidea) of bark beetles in pine ( spp.) plantations were studied in Bulgaria. Samples (cuttings of stems and branches) of pine trees infested by bark beetles were collected from seven plantations of and in Bulgaria. From each sampling plot, five cuttings were collected and placed in photoeclectors in laboratory conditions (18-22ºC). Emerged bark beetles and parasitoids were regularly gathered and fixed in ethanol.
Six parasitoid species - , , , , (Chalcidoidea: Pteromalidae) and (Chalcidoidea, Heydeniidae) were reared from five bark beetle hosts (, , , and ). Amongst them, three species (, and ) are recorded as new for Bulgarian fauna.
2020年和2021年，在保加利亚对松树（松属）人工林中树皮甲虫的小蜂类寄生蜂（膜翅目，小蜂总科）进行了研究。从保加利亚7个松属和云杉属人工林中收集了被树皮甲虫侵害的松树样本（茎和枝的插条）。从每个采样地收集5个插条，并置于实验室条件（18 - 22摄氏度）的光电采集器中。定期收集羽化出的树皮甲虫和寄生蜂，并用乙醇固定。
从5种树皮甲虫寄主（云杉八齿小蠹、欧洲山松大小蠹、黑脂大小蠹、落叶松八齿小蠹和云杉四眼小蠹）中饲养出6种寄生蜂——长角刻腹小蜂、双钩刻腹小蜂、拟长尾金小蜂、黄胸金小蜂、多色金小蜂（小蜂总科：金小蜂科）和海氏小蜂（小蜂总科，海氏小蜂科）。其中，有3个物种（长角刻腹小蜂、双钩刻腹小蜂和海氏小蜂）被记录为保加利亚动物区系新物种。
