食草昆虫蓼蓝齿胫叶甲初步研究

蓼蓝齿胫叶甲在政治一年发生一代，以成虫在土壤中越冬。成虫、幼虫均以蓼科杂草为食，是麦田中扁蓄，水蓼等有害杂草的重要天敌。本文对蓼蓝齿胫叶甲各虫态形态特征，年生活史与生活习性，发育起点温度与有效积温，田间发生动态，发生与环境的关系，寄主范围、成虫与幼虫食量及在田间对蓼科杂草的封闭和了报道。

PRELIMINARY STUDIES ON THE HERBIVOROUS INSECT GASTROPHYSA ATROCYANEA

Gastrophysa atrocyanea has only one generation in a year in the Province of Hubei. The adults overwinter in the soil. The adults and larvae all fed on Polyg-onaceae weeds. It was an important natural enemy of the weeds in the fields of wheat. This paper reported the morphological and biological characters of each stage of Gastrophysa atrocyanea, the population dynamics, the special hosts and the capacity for eating. Under natural condition, Gastrophysa atrocyanea may effectively control the weeds in the fields.
