Longevity toxicity after chronic α -endosulfan exposure in wild population of Drosophila melanogaster Oregon-R (Diptera: Drosophilidae)

Abstract

The rapid increase in the world population causes different problems such as nutrition and shelter. In this case, people brutally destroy arable land to shelter, and concretization is rapidly spreading. In addition, it is necessary to increase the amount of products to be taken from the limited agricultural areas for the food needs of the increasing population. The decrease in agricultural areas appears as a factor that reduces the amount of product taken from the unit area. In addition, weeds and especially insects reduce the yield, storage, and marketing quality of products obtained from restricted areas. This type of plant products can also be considered a disease carrier vector in the food chain. To increase the yield, various insecticides have been developed against target organisms such as insects and one of these insecticides is α-endosulfan. However, non-target organisms living in the same ecosystem can also be affected by all these insecticides. In the present study, it was researched whether the chronic α-endosulfan application has an effect on longevity in non-target organisms. According to the data obtained, α-endosulfan shortened the maximum and mean lifespan in both male and female populations of the Oregon-R wild strain of Drosophila melanogaster based on dose-time interaction. The shortening observed in life span for both populations was statistically significant (p
