摘要
描述了临夏州新发生害虫梨斑叶甲的形态特征，系统地研究了该虫的生物学特性和发生、危害规律；通过室内药剂毒力测定和田间防治试验，筛选出了最佳防治药剂浓度组合；并提出了今后的防治对策。
On the basis of describing morphological characters of a pestpear spotted leaf bettle (Paropsides Soriculata) newly occurred in Linxia prefecture of Gansu, this paper give systematic studies to biological characters and occurrying law. Moreover, the indoor determination of toxic effect of insecticide against the pest and the prevention and control field trial have been done.
