摘要： 通过对水稻、茭白二化螟（Chilo suppressalis）蛹进行形态特征的数值分析，结果表明水稻二化螟、茭白二化螟蛹形态的几个指标存在差异，但其不能截然分开。用主成分分析并绘制二维排序图，发现水稻二化螟、茭白二化螟交迭在一体。

Abstract:

Morphology characteristics for the striped stem borer pupae associated with rice or water oats was analyzed. Result indicated that there were some differences on morphology quotas for the striped stem borer pupae associated with rice or water oats, which were not differentiated distinctly. Two dimension distribution figure was drawn by principal component analysis, which revealed that the striped stem borers overlapped.

Key words: striped stem borer, pupa, morphology, host, population
