Yabanıl tip ve hedef olmayan model bir organizmanın, Drosophila melanogaster Oregon-R, dişi ve erkek popülasyonlarında bakır hidroksit (Cu(OH)2) nanopestisitine ait etkilerin in vivo ömür uzunluğu testi ile araştırılması

Abstract

Bağ, zeytin ve turunçgil ekili bakır içeren topraklarda kullanılan bakır hidroksit (bir çeşit fungusit) inovatif bir nanopestisittir. Ancak geleneksel pestisitlerin yerini alan nanopestisitler, hedef organizmalar kadar hedef olmayan organizmaları da (omurgalı ya da omurgasız) etkileyebilmektedirler. Bu durum özellikle biyoçeşitlilik bakımından önemli bir risk faktörüdür. Bu çalışmada böyle bir riskin olup olmadığını araştırabilmek için Drosophila melanogaster Oregon-R’nin dişi ve erkek popülasyonlarına in vivo ömür uzunluğu testi uygulanmıştır. Farklı dozlarda (10, 20, 40 ve 80 ppm) Cu(OH)2 nanopestisitinin kronik olarak uygulanması ile her iki popülasyonda hem maksimum hem de ortalama ömür uzunluğunun kontrol grubuna göre azaldığı görülmüştür (p<0,05).

Investigation of the effects of copper hydroxide (Cu(OH)2) nanopesticide on female and male populations of a wild-type and non-target model organism, Drosophila melanogaster Oregon-R, by in vivo longevity test

Abstract

Copper hydroxide (a type of fungicide) is an innovative nanopesticide used in vineyard, olive and citrus cultivated copper-containing soils. However, nanopesticides, which replace traditional pesticides, can affect non-target organisms (vertebrates or invertebrates) as well as target organisms. This situation is an important risk factor, especially in terms of biodiversity. In this study, in vivo longevity testing was applied to male and female populations of Drosophila melanogaster Oregon-R to investigate whether there is such a risk. With the chronic application of Cu(OH)2 nanopesticide at different doses (10, 20, 40 and 80 ppm), it was observed that both maximum and average lifespan decreased in both populations compared to the control group (p<0.05).
