Abstract
This study was conducted in the rangelands of Erzurum Center, Ilıca, Aşkale and Çat districts to determine Cicadellidae (Homoptera) species and their relationships with some rangeland quality factors in 2001. During the surveys in 86 areas, totally, 34 species were determined. Among these species, Circulifer haematoceps (Mulsans and Rey) with 709 specimens from 72 localities; Stenometopiellus angorensis (Zachvatkin) with 289 specimens from 51 localities; Doratura exilis (Horvath) 212 specimens from 36 localities were found as most widespread species. The soil samples were taken from each survey area, and distance to village, stony, slope, grazing, altitude, erosion and depth of soil were recorded. Relationships between the number of specimens in the research areas and some rangeland quality factors, distance to village, stony, slope, grazing, altitude, erosion and depth of soil, were studied. Analysis of the data revealed that negative very significant relationship between density of C. haematoceps and grazing, and positive very significant relationship between the insect density and altitude (P
Özet
Cicadellidae (Homoptera) türlerinin mera kalite faktörleriyle ilişkisini belirlemek amacıyla, 2001 yılında Erzurum Merkez, Ilıca, Aşkale ve Çat ilçelerindeki meralarda 86 noktada yürütülen çalışmada, toplam 34 tür belirlenmiştir. Bunlardan, Circulifer haematoceps (Mulsant and Rey) 72 noktadan elde edilen 709 birey; Stenometopiellus angorensis (Zachvatkin) 51 noktadan 289 birey; Doratura exilis (Horvath) ise 36 noktadan 212 birey ile en yaygın türlerdir. Her sürvey noktasından toprak örnekleri alınmış, köye uzaklık, taşlılık, eğim, otlatma, rakım, erozyon ve toprak derinliği gibi özellikleri kaydedilmiştir. Bu alanlarda bulunan birey sayısı ile mera kalitesini belirleyen faktörlerden köye uzaklık, taşlılık, eğim, otlatma, rakım, erozyon ve toprak derinliği arasındaki ilişkiler incelenmiştir. Buna göre, C. haematoceps yoğunluğu ile otlatma arasında olumsuz çok önemli, rakım arasında ise olumlu çok önemli ilişki (P
