Table 1: Taxonomic characteristics of the bacterial microbiome inhabiting the digestive system of _S. oryzae_ and _R. dominica._Based on the Kaplan-Meyer test results, significant differences in the _S. oryzae_ survival rate (\(p<0.05\)) occurred in the starving insects (background) (survival rate 1.6 after seven days of culture) compared to the control, antibiotic doses of 10, 20, 30, and 40 mg:g\({}^{-1}\), and antibiotic doses of 0, 10, and 20 mg:g\({}^{-1}\) (survival rate \(\sim\)0.94) versus 30, 40, and 50 mg:g\({}^{-1}\) (survival rate 0.19-0.46). It was observed that the survivability of the insects at an antibiotic dose of 30 mg:g\({}^{-1}\) did not differ from that observed at 40 mg:g\({}^{-1}\), but was significantly lower than the survival rate determined at a gentamicin dose of 50 mg:g\({}^{-1}\) (Figure 3a). Figure 2: Boxplot showing changes in the number of bacteria (colony-forming units (CFU) in the consecutive days of culture on food contaminated with antibiotics (the initial number of bacteria for _S. oryzae_ was 201 CFU and for _R. dominica_ 40 CFU); D0: no antibiotic in the diet, D10 to D50: doses from 10 to 50 mg:g\({}^{-1}\) of the antibiotic in the feed. The survival rate of _R.
