Abstract
Anisoplia spp. (Ekin bambul böceği), hem dünyada hem de ülkemizde buğday ekim alanlarında önemli ürün kayıplarına neden olan zararlı türlerden biridir. Bu çalışmada zararlının Van ili ve ilçelerinde bulunan buğday alanlarında, Anisoplia cinsine bağlı türler, yayılışları ve ilçelere göre yoğunlukları saptanmıştır. Bu amaçla 2021 yılı Nisan-Ağustos aylarında belirlenen bölgelerde aylık periyotlar ile surveyler yapılmış ve örnekler toplanmıştır. Örneklemelerde standart atrap ve elle toplama yöntemleri uygulanmıştır. Anisoplia spp. Çatak ilçesi dışında tüm örnekleme alanlarında tespit edilmiştir. Çalışma alanlarında Anisoplia (Coleoptera: Scarabaeidae: Rutelinae) cinsine bağlı Anisoplia austriaca, A. signata, A. lata, Brancoplia leucaspis, Blitopertha nigripennis, Chaetopteroplia segetum ve tür tanısı yapılamayan Anisoplia sp. türleri tespit edilmiştir. Bu türler arasından bütün ilçelerde en yaygın ve en yoğun olarak Chaetopteroplia segetum türü tespit edilmiştir. Van ve çevresinde tespit edilen bu türlerin tamamı bölge için ilk kayıtlardır. Genel olarak, Anisoplia türlerinin bölgede ekonomik anlamda zarar yapabilecek yoğunluklarda olmadıkları gözlenmiştir.
Anisoplia spp. (The Grain Beetle) is one of the harmful species that cause significant crop losses in wheat cultivation areas wherein our Country and in the World. In this study, the species belonging to the genus Anisoplia, their distribution and density according to the regions were determined in the wheat fields in Van province and its districts. For this purpose, monthly surveys were carried out in the determined regions in April-August 2021 and samples were collected. Standard sweepnet and handling methods were used for the sampling. Anisoplia spp. has been found in all sampling areas except Çatak district.
