Abstract

In this study, the effects of the organophosphorus insecticide diazinon on antioxidant enzyme activities, and female and total adult emergence ratios of Pimpla turionellae L., were investigated when using a synthetic diet containing 0.01, 0.10, 0.25, 0.50 and 0.75 ppm of the insecticide. Sublethal concentrations of diazinon were supplied to P. turionellae for 24, 48, 72 and 96 hours for enzyme activity and thirty days for determining emergence ratios. P. turionellae gave different antioxidant responses to insecticidal stress, depending on the concentrations and diazinon exposure time. When compared to the control and especially in high concentrations (0.50 and 0.75 ppm), diazinon increased SOD activity. Although diazinon also caused increases in CAT activity, these increases were not consistent.This study found that the CAT activity didn't fall below the control level. Diazinon significantly reduced female and total adult emergence of P. turionellae and SOD played a more significant protective role against diazinon toxicity.

Özet

Organofosforlu bir insektisitin Pimpla turionellaenin antioksidan enzim aktivitelerine ve toplam ve dişi birey çıkışına olan etkileri 0.01, 0.10, 0.25, 0.50 ve 0.75 ppm diazinon içeren sentetik besin kullanılarak araştırıldı. Subletal diazinon konsantrasyonları, antioksidan enzim aktivitelerini belirlemek için 24, 48, 72 ve 96 saat süreyle, ergin birey çıkışını belirlemek için ise 31 gün boyunca P. turionellaeya verildi. P. turionellae insektisit stresi altında diazinonun dozuna ve maruz kalma süresine bağlı olarak farklı tepkiler gösterdi. Diazinon özellikle yüksek konsantrasyonlarda (0.50 ve 0.75 ppm) SOD aktivitesinin kontrole göre önemli ölçüde artmasına neden oldu. Bununla beraber CAT aktivitesinde düzensiz artışlara neden oldu. Çalışmadaki önemli bir bulgu, CAT aktivitesi hiçbir konsantrasyonda kontrol seviyesinin altına düşmedi. Toplam ergin ve dişi çıkışı diazinondan önemli ölçüde etkilenerek azaldı. Sonuç olarak, SODnin P. turionellaede diazinon toksisitesine karşı çok önemli bir koruyucu rol oynadığı ve diazinonun toplam ve dişi birey çıkışını önemli ölçüde azalttığı belirlendi.
