Antimicrobial Activity of the Antimicrobial Peptides Extracted from Immunized Tenebrio molitor Induced by Different Microbial Treatments Against 26 Pathogens

[Objective] The study was to explore whether antimicrobial activity of the antimicrobial peptides extracted from immunized Tenebrio molitor vary with different pathogens as inducers.[Method] By inducing hungry T.molitor larvaes to generate immune response via feeding with bacteria and with fungi or actinomycete after pricking,the antimicrobial peptide extract was obtained by grinding and centrifuging the cultures.Its antimicrobial activity against 26 pathogens was measured by bacteriostatic ring,and evaluated by trisection to four types and inhibitory spectrum.[Result] Both the antimicrobial activity and antimicrobial spectrum of the antimicrobial peptide extract varied remarkably among different pathogens as inducers.[Conclusion] Bio-control used strains have obvious advantage in inducing the insect to express body fluid immunity material-antimicrobial peptides.
