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

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
