[ Objective ] The research aimed to study the pupa changes and emergence behaviors of Dacne picta Crotch. [ Method ] The D. p/cta reared in the labo- ratory were observed and recorded. [ Result ] Before the emergence, the color of compound eyes, maxillae, tarsi and wing pads d pupae was gradually deepened. The 14^th- 16^th d after pupation were the peak time for emergence, and the ratio of female to male was close to 1： 0.77. During the emergence, the puparium of D. picta dehisced from pronotum, and the hind wing had extension phenomenon before contraction and folding. [ Conclusion] The research confirmed the pupa changes and the emergence behaviors of D. picta.
[Objective] The study was to explore whether antimicrobial activity of the antimicrobial peptides extracted from immunized Tenebrio molitor varied with different pathogens as inducers.[Method]By inducing T.molitor hungry larvaes to generate immune response via feeding with bacteria and with fungi or actinomycete post to pricking,the antimicrobial peptides extracts were 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 peptides extracts 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.
