Influence of climatic conditions on microsporidiosis that originated from Rugispora istanbulensis in Elm Leaf Beetle, Xanthogaleruca luteola Muller (Coleoptera: Chrysomelidae)

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 ？stanbul. 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)
