<i>P. xylostella</i> mortality after oral infection with <i>P. taiwanensis</i> wild-type and Δ<i>tccC</i> strains or their cell lysate, sonicated pellet, sonicated supernatant, or culture supernatant on day 5.

aP. taiwanensis wild-type, ΔtccC mutant strains, and their various proteins fractions were fed to three instar of healthy larvae. bMortality is the percentage of larvae death. n is the sample size of the treated groups. The data were collected on day 5. cThe two tail student t-test was used to elucidate statistical significance. Each treatment was repeated three times. dSimilarity with b, n is the sample size of the negative control PBS-treated group. eIngestion dose: 50 µl OD = 0.5, 1, 2 cells/0.5×1 cm2 vegetable block. fIngestion dose: The crude extract contained 300 ng of proteins.
