Pests that pose a risk in terms of agriculture and livestock cause economic losses directly or indirectly. However, some pests are also vectors of various diseases that threaten the health of living things, especially of humans. Therefore, the detection of maternally inherited reproductive manipulator endosymbiotic bacteria is important in the development of alternative strategies to chemical methods in the fight against pests. In this study, the endosymbiotic Arsenophonus, Cardinium, Hamiltonella, Rickettsia, Spiroplasma and Wolbachia in gallery fly (leaf miner fly) (Liriomyza sp.), legume seed beetle (Bruchus sp.), tomato pest Lasioptera sp., cattle louse (Bovicola bovis) and winged red mite (Dermanyssus gallinae) scanning was carried out. As a result of the scans, we could not detect any of the endosymbiotic bacteria studied. This study includes the first known data from Anatolia regarding maternally inherited reproductive manipulator endosymbiotic bacteria in Liriomyza sp., B. pisorum, B. bovis and D. gallinae pests.
