A Taxonomic Study on Chelonus Panzer, 1806 (Hymenoptera, Braconidae, Cheloninae) Fauna of Central Anatolian Region of Turkey

Öz

The study was carried out to determine the species of the genus Chelonus Panzer, 1806 (Hymenoptera, Braconidae, Cheloninae) in Central Anatolia Region between 2007 and 2009. Cheloninae species are solitary koinobiont egglarval endoparasitoids on Lepidoptera (especially Tortricoidea and Pyraloidea) and Coleoptera. For this reason, members of this group are potentially very important biological control agents for the pest insects. Samples were collected from short plants using standard insect sweeping nets, transferred into tubes containing 70% ethanol and labeled following their preparations according to museum techniques. Samplings were performed in 45 localities and 14 species of Chelonus were determined of which Chelonus (Chelonus) carbonator Marshall, 1885 is a new record for Turkey fauna. The distributional ranges of already known species were expanded with the addition of new records for these species. The distributions of the determined species in Turkey as well as their general distributions were given and discussed zoogeographically. C. (C.) oculator is found in 30 of the 45 habitats, and appears to perform the highest ecological valance.

İç Anadolu Bölgesi Chelonus Panzer, 1806 (Hymenoptera, Braconidae, Cheloninae) Faunası Üzerine Taksonomik bir Araştırma

Öz

Bu çalışma, İç Anadolu Bölgesi’nde bulunan Chelonus Panzer, 1806 (Hymenoptera, Braconidae, Cheloninae) cinsi türlerini belirlemek amacıyla 2007-2009 yılları arasında yürütülmüştür. Cheloninae türleri Lepidoptera (özellikle Tortricoidea ve Pyraloidea) ve Coleoptera takımları üzerinde soliter koinobiont yumurta-larva endoparazitoidleridirler. Bu yüzden bu grubun üyeleri zararlı böcekler için önemli bir potansiyel biyolojik mücadele etmenidirler. Örnekler böcekleri toplamakta kullanılan atraplar kullanarak kısa boylu bitkiler üzerinden toplanmış ve % 70 ‘lik alkol içeren öldürme tüplerinde öldürüldükten sonra müze tekniklerine uygun olarak prepare edilip etiketlenmiştir. 45 lokalitede araştırma yapılmış ve değerlendirme sonucu Chelonus cinsine ait 14 tür elde edilmiştir. Saptanan türlerden Chelonus (Chelonus) carbonator Marshall, 1885 Türkiye faunası için yeni kayıttır. Ayrıca bilinen türlere ait yeni kayıtlarla da bu türlerin Türkiyedeki dağılım sınırları genişletilmiştir. Saptanan türlerin, Türkiye ve genel coğrafi dağılımları verilerek zoocoğrafik dağılımları tartışılmıştır. Araştırılan 45 habitattan 30’unda bulunan C. (C.) oculator’un ekolojik valansı en yüksek tür olduğu belirlenmiştir.
