Table 2 CFU analysis of difference in cultivable gut bacteria of E.obliqua larvae between control groups and EGCG treatment groups (n = 5). (10−3, 10−4, 10−5) are dilution mutiples; CK: larvae feed on artificial diet; T: larvae feed on artificial diets containing 1% EGCG; CK + E. coli: After larvae feed on artificial diets five days, we switched to feed on artificial diets containing 20 ml Escherichia coli for 24 hours; T + E. coli: after larvae feed on artificial diets containing 1% EGCG five days, we switched to feed on artificial diets containing 20 ml Escherichia coli for 24 hours.
