Mosquitoes have adapted to various environmental conditions. Symbionts with mosquitoes impact this adaptation in different environments. In the field, mosquitoes could get exposed to antibiotics during their developmental period, which could reduce or eliminate their symbiotic microbes. However, the side effects of the antibiotics on the ovary and reproductive physiology of the Asian tiger mosquito, Aedes albopictus remains unknown. In this study, we investigated the effects of tetracycline and combinations of rifampicin and tetracycline at environmentally acceptable levels on the reproductive physiology of ovaries in Ae. albopictus . Rifampicin and tetracycline in combination reduced the hatching rate and fertility of Ae. albopictus compared to the untreated control group. These antibiotics induced histopathological damage and reactive oxygen species production in the ovaries. The combination of antibiotics decreased the expression of surface protein of Wolbachia (WSP) in Ae. albopictus . Additionally, the expression of Toll like receptor 2 (TLR2) and Myd88 were triggered by the combinations. The findings demonstrate the detrimental effects of antibiotics, particularly combinations of rifampicin and tetracycline, on the reproductive capacity of Ae. albopictus females.
