Pestisit Uygulanmış Vermikompostta Eisenia fetida (Savigny, 1826)’nın Bazı Biyolojik Parametreleri

Bu çalışmanın amacı, pestisit uygulanmış vermikompostlarda kırmızı Kaliforniya solucanının (Eisenia fetida) bazı biyolojik parametrelerini belirlemektir. Çalışma in-vitro şartlarda, Tesadüf Parselleri Deneme Düzeninde 5 tekerrürlü olarak yapılmıştır. Pestisit muamelesinde, Muş ilinde çokça kullanılan bazı pestisitler (Granland®, Demond® ve Safacol®) kullanılmıştır. Deney ortamının sıcaklığı 20-29oC ve nem oranı %70-90 arasında tutulmuş ve deney, kokonlardan çıkan yavru bireylerin tekrar kokon vermesine kadar devam etmiştir. Muamelelerinin belirlenen özelliklere etkisinin araştırılmasında Tek Yönlü Varyans Analizi Tekniğinden (One-way ANOVA), farklı grupların belirlenmesinde ise TUKEY Çoklu Karşılaştırma Testi’nden yararlanılmıştır. Yapılan varyans analizi sonucunda; solucan ağırlığı bakımından fungisit dozları arasında istatistiksel olarak önemli farkların bulunmadığı (P=0.113), buna karşın insektisit ve herbisit dozları bakımından söz konusu farkların önemli olduğu görülmüştür (P=0.000). Kokon ve solucan sayıları bakımından ise pestisit dozları arasında önemli farkların bulunduğu tespit edilmiştir (P=0.000).

Some Biological Parameters of Eisenia fetida (Savigny, 1826) in Pesticide-Applied Vermicompost

The objective of this study was to determine some biologicalparameters of red California worm (Eisenia fetida) in pesticidesapplied vermicompost. The study conducted under in-vitro conditions,as Randomized Block Design with five raplications. Commonly usedGranland®, Demond® and Safacol® pesticides in Muş province(Turkey) were used as treatments. The temperature and humidityratio for the experiment were 20-29°C and 70 to 90%, respectively.The experiments were resumed until the young worms hatched froma cocoon reproduced cocoons again. For investigating the effect of thetreatments on specific features One-Way Analysis of Variance (Oneway ANOVA) and for determining of different groups TUKEYMultiple Comparison Test were used. Variance analysis indicatedthat there was no statistically differences among fungicide doses interms of worm weight (P=0.113); however, there were differences interms of insecticide and herbicide doses (P=0.000). It was detectedthat there were significant differences among pesticide doses inrespect to the cocoon and worm numbers (P=0.000).
