The paper analyzes the effect of oil on the survival and fertility of Drosophila melanogaster lines that differ in oil resistance. A study was made of wing morphoses in female flies of oil-resistant lines and flies, oil-resistant lines in a pure nutrient medium. In studies conducted at the Department of Ecology and Genetics, an oil-resistant line of fruit flies was bred, capable of not only surviving, but also reproducing in conditions of high oil concentration: half of the semi-lethal (2.5%) and semi-lethal (5%). The main indicators of the vital activity of flies reached the level of control (do not differ from the standard) by the 60th - 70th generation of keeping in conditions of oil pollution. Currently, flies kept, living and breeding in an oil-polluted environment have gone through more than 600 generations of development. Options used in the experiment: control contained on a standard nutrient medium; flies adapted to semi-lethal (5%) concentration of oil in the environment; flies adapted to half of the semi-lethal (2.5%) concentration of oil in the environment; flies adapted to 5% concentration, but transplanted to a pure nutrient medium (non-adaptive conditions); flies adapted to 2.5% concentration, but transplanted to a pure nutrient medium (non-adaptive conditions). Of interest was the opportunity to analyze the main indicators of vital activity and the presence of wing morphoses of fruit flies of an oil-resistant line, under conditions of oil pollution and when transferred to a clean nutrient medium (maladaptive conditions).
