The effect of Pyrethrum and Bacillus thuringiensis against Pristiphora abietina (Christ, 1791) (Hymenoptera: Tenthredinidae)

Öz

This work has been done for the purpose of creating a complete struggle strategy against Pristiphora abietina (Christ), which is the cause of the spoil in Artvin Savsat spruce forests in the recent years and Pyrethrum and Bacillus thuringiensis biopesticides effects has been investigated and put into practice on the P. abietina. Under laboratory conditions, Pyrethrum (Spruzit Neu) and B. thuringiensis (Dipel DF) biopesticides were administered at different doses to the larvae of P. abietina and the results were evaluated according to the One Way Analysis of Variance and Duncan Test. The most effective applications for larval applications have been determined that Dipel 100 gr / 100 lt, Dipel 300 gr / 100 lt and Dipel 500 gr / 100 lt. The Pyrethrum (Spruzit Neu) efficiency ratio was determined 71.7% dose of 150 ml / 100 lt,   81% dose of 300 ml / 100 lt, 93.2% dose of 600 ml / 100 lt and  Dipel DF was found to be 91.5% dose of 100 g / 100 lt,  93.6% dose of 300 gr / 100 lt and  98.8% dose of 500 gr / 100 lt, respectively. As a result, using of both biopesticides have been effective to against on larvae of P. abietina.

Pyrethrum ve Bacillus thuringiensis biyopestisitlerinin Pristiphora abietina (Christ, 1791) (Hymenoptera: Tenthredinidae) üzerindeki etkisi

Öz

Son yıllarda Artvin Şavşat ladin ormanlarında zarara neden olan Küçük Ladin Arısına (Pristiphora abietina (Christ)) karşı tam bir mücadele stratejisi oluşturabilmek amacı ile  2014 yılında yapılan bu çalışmada; Pyrethrum ve Bacillus thuringiensis biyopestisitlerinin P. abietina üzerindeki etkisi araştırılarak uygulanabilirliği ortaya konulmaya çalışılmıştır. Laboratuvar şartlarında, P. abietina’nın larvalarına karşı farklı dozlarda Pyrethrum (Spruzit Neu) ve B. thuringiensis (Dipel DF) biyopestisitleri ile uygulamalar yapılarak sonuçlar Tek Yönlü Varyans Analizi ve Duncan Testi’ne göre değerlendirilmiştir.  Larvalar için en etkili uygulamaların Dipel 100 gr/100 lt, Dipel 300 gr/100 lt ve, Dipel  500 gr/100 lt uygulamaları olduğu tespit edilmiştir. Pyrethrum (Spruzit Neu)’un 150 ml/100 lt dozunda % 71.7, 300 ml/100 lt dozunda % 81, 600 ml/100 lt dozunda % 93.2, Dipel DF’in 100 gr/100 lt dozunda % 91.5, 300 gr/100 lt dozunda % 93.6, 500 gr/100 lt dozunda ise % 98.8 etkinlik oranı belirlenmiştir. Sonuç olarak, kullanılan her iki biyopestisitinde P. abietina’nın larvalarına karşı etkili olduğu tespit edilmiştir.
