Antibiotic Treatment Reduced the Gut Microbiota Diversity, Prolonged the Larval Development Period and Lessened Adult Fecundity of Grapholita molesta (Lepidoptera: Tortricidae).

Another reason may be that the antibiotic types screened in vitro only inhibit the culturable bacteria in the I G. molesta i gut, while the inhibitory effect on the unculturable bacteria is unknown. In this study, after treatment with ciprofloxacin, there was no increase of the non-dominant bacteria to the dominant bacteria in the intestinal microbiota of I G. molesta i , but only changes in the relative abundance of the dominant bacteria. However, the minimum inhibitory concentration of ciprofloxacin against the intestinal bacteria of I C. capitata i was 5 g/mL, which was much higher than the 1 g/mL in this study, indicating that the intestinal bacteria of I G. molesta i were more sensitive to ciprofloxacin [[35]].
