Parasitoids of the small poplar longhorn beetle, Saperda populnea (L.) (Coleoptera: Cerambycidae), in the Aras valley (Kars and Erzurum provinces), Turkey

Aras Vadisi’nde 2006 ve 2007 yıllarında Saperda populnea (L.) (küçük kavak teke böceği) (Coleoptera: Cerambycidae)’nın parasitoitleri çalışıldı ve kışlayan larvalardan Paraperithous gnathaulax (Thomson), Dolichomitus populneus (Ratzeburg), Dolichomitus tuberculatus (Geoffroy) (Hymenoptera: Ichneumonidae), Ipbiaulax impostor (Scopoli) (Hymenoptera: Braconidae), and Billaea irrorata (Meig.) (Diptera: Tachinidae) olmak üzere beş parasitoit türü elde edildi. Bunlardan D. populneus, yoğunluğu en yüksek olan tür olup tüm parasitoit bireylerinin % 55’ini oluşturmaktadır. Ipbiaulax impostor ve B. irrorata türleri, ülkemizde S. populnea’dan ilk defa bu çalışma ile elde edildiği gibi, B. irrorata Türkiye faunası için yeni kayıt durumundadır.

Aras vadisi'nde (Kars ve Erzurum) Saperda populnea (L.) (küçük kavak tekeböceği) (Coleoptera: Cerambycidae)' nın parasitoitleri

The parasitoids of the small poplar longhorn beetle, Saperda populnea (L.) (Coleoptera: Cerambycidae), were studied in the Aras Valley (Kars and Erzurum provinces), Turkey, during 2006-2007. Five parasitoid species, Paraperithous gnathaulax (Thomson), Dolichomitus populneus (Ratzeburg), Dolichomitus tuberculatus (Geoffroy) (Hymenoptera: Ichneumonidae), Ipbiaulax impostor (Scopoli) (Hymenoptera: Braconidae), and Billaea irrorata (Meig.) (Diptera: Tachinidae), were reared from the overwintering larvae living in the galls of S. populnea. Dolichomitus populneus was the most numerous of the parasitoids and accounted for 55% of all parasitoids reared. Ipbiaulax impostor and B. irrorata were reared from S. populnea for the first time in Turkey. Additionally, B. irrorata is a new record for the Turkish fauna.
