The induction of transposition of ТЕ mdgl has been analysed at the different stages of spermatogenesis in isogenic lines of males № 2-2 и № 16 of Drosophila melanogaster exposed to Cold Shock (CSh) and Heat Shock (HSh). We found that in response to CSh and HSh multiple transpositions of mobile elements mdgl occur in each stage of spermatogenesis. It was found that meiosis was the most sensitive stage to CSh. Exposure to HSh caused the highest rate of transpositions in the meiosis and spermatogenesis stages
