Aim. The main goal of this article was to assess changes in the frequency of the development of hybrid dysgenesis in the Oregon-R line of Drosophila melanogaster, observed under the influence of tetracycline. Methods. The line of Drosophila melanogaster Oregon R (Cambridge), in the genome of which there are full-sized and functionally active copies of the MGE hobo, was investigated. Also, this line is infected with wolbachia of the wMel strain. Removal of Wolbachia from the body was implemented using antibiotic tetracycline. The level of hybrid dysgenesis was studied by the method of extracting gonad flies and assessing their condition. Results. This article presents the results of studying the effect of suppression of the internal microflora of Drosophila melanogaster – in particular, the parasitic bacterium Wolbachia pipientis - on the level of manifestation of hybrid dysgenesis. After exposure to tetracycline, a significant increase in the proportion of dysgenic individuals within the line was observed. Conclusions. The results obtained may be associated with a violation of the system of specific interactions of the host organism and internal microflora.
