Abstract

Aim of study: This study was conducted to determine climatic conditions conducive for the spread and persistence of microsporidian infection of Rugispora istanbulensis in elm leaf beetle, Xanthogaleruca luteola.

Area of study: The samples were collected from May to September between 2013 and 2015 in İstanbul.

Material and Methods: Each month a hundred of X. luteola individuals were dissected and a total of 1500 beetle examined with the light microscope for three years. In this study, all statistical analyzes carried with the SPSS 21 (SPSS Inc. 1989-2012) software program.

Main results: The results indicated that the year 2014 was the most intensive year of microsporidiosis with a frequency rate of 21.48%. There was a strong correlation between the frequency of microsporidiosis and humidity (r = 0.455, P<0.01).

Research highlights: The temperature was the main determinative factor for the prevalence of microsporidiosis that originated from R. istanbulensis in elm leaf beetles (t=13.671).

Karaağaç yaprak böceği, Xanthogaleruca luteola Muller (Coleoptera: Chrysomelidae)’ da Rugispora istanbulensis kaynaklı microsporidiosis üzerine iklim koşullarının etkisi

Abstract

Çalışmanın amacı: Bu çalışma, karaağaç yaprak böceği, Xanthogaleruca luteola Muller (Coleoptera: Chrysomelidae) 'da bir mikrospor türü olan Rugispora istanbulensis enfeksiyonunun yayılımı ve oluşumu için uygun iklim koşullarının belirlenmesi amacıyla yapılmıştır.

Çalışma alanı: Çalışma örnekleri 2013-2015 yıllarının Mayıs ile Eylül ayları arasında İstanbul’dan toplandı.

Materyal ve Yöntem: 2013-2015 yılları arasında her ay 100 X. luteola bireyi disekte olacak şekilde 3 yıl boyunca toplamda 1500 örnek ışık mikroskobu kullanılarak incelendi. Bu çalışmadaki tüm istatiksel analizler SPSS 21 (SPSS Inc. 1989-2012) adlı istatistik programı kullanılarak gerçekleştirildi.

Sonuçlar: 2014 yılı çalışma yılları arasında %21,48 mikrosporidiosis oranı ile en yoğun mikrospor enfeksiyonunun görüldüğü yıl olarak tespit edildi. Yapılan korelasyon analizlerine göre, nem ile microsporidiosis arasında güçlü bir korelasyon olduğu tespit edildi (r = 0.455, P<0.01).

Önemli vurgular: Karaağaç yaprak böceklerinde R. istanbulensis kaynaklı mikrosporidiosis yaygınlığı için sıcaklık ana belirleyici faktördür (t = 13.671).
