Türkiye’nin Batısında, Kütahya İlinde Sphaeridium Fabricius, 1775 (Coleoptera: Hydrophilidae) Cinsi Üzerine Bir Çalışma

Türkiye batısında Kütahya’da, Haziran 2010’dan Mayıs 2011’e kadar, 14 lokalitede ve farklı yüksekliklerde (469m-1810m) yemli çukur tuzaklar kullanılarak koprofil Hydrophilidae örnekleri toplanmıştır. Çalışma sonucunda toplam 5 türe ait 668 örnek tespit edilmiştir. Toplanan örneklerin Sphaeridium bipustulatum Fabricius, 1781, S. lunatum Fabricius, 1792, S. marginatum Fabricius, 1787, S. scarabaeoides (Linnaeus, 1758) ve S. substriatum Faldermann, 1838 türlerine ait oldukları belirlenmiştir. S. lunatum Türkiye’den ilk kez kayıt edilmiştir. Toplanan böceklerin %80,69'unu oluşturan S. bipustulatum ve S. marginatum en baskın türler olarak belirlenmiştir. Aralık ayından Nisan ayına kadar yoğun örnek elde edilmiş olması, çalışma alanı içerisindeki Sphaeridium popülasyonlarının kış ve ilkbahar döneminde en yüksek birey sayılarına ulaştığını göstermektedir.

A STUDY ON THE GENUS Sphaeridium FABRICIUS, 1775 (COLEOPTERA: HYDROPHILIDAE) IN KÜTAHYA PROVINCE, WESTERN TURKEY

Coprophilous Hydrophilidae were sampled from June 2010 to May 2011 using baited pitfall traps in 14 localities at different altitudes (469m-1810m) in Kütahya, western Turkey. As a result of the study, a total of 668 samples belonging to 5 species were identified. The identified specimens are Sphaeridium bipustulatum Fabricius, 1781, S. lunatum Fabricius, 1792, S. marginatum Fabricius, 1787, S. scarabaeoides (Linnaeus, 1758) and S. substriatum Faldermann, 1838, among which S. lunatum is recorded from Turkey for the first time. S. bipustulatum and S. marginatum, which made up 80.69% of all collected beetles determined as eudominante. The highest number of specimens was obtained from December to April meaning that the Sphaeridium community in the study area reached its highest number in winter and spring.
