摘　　要：[ 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 research aimed to study the pupa changes and emergence behaviors of Dacne picta Crotch.
