该文研究了光肩星天牛的生物学特性，在呼市地区二年发生一代，以老熟幼虫、初龄幼虫及未孵化的幼虫在卵壳内均可越冬，也有极少数的以蛹越冬。成虫６月下旬始见，７月中旬进入高峰期，８月中旬进入盛末期。雌虫平均产卵量为２２粒。卵始见期为７月上旬，始盛期为８月上旬，高峰期为８月下旬，盛末期为９月上旬。该文提出的发生期、发生量的预测预报方法具有实用价值。 In this paper, the biological characteristics of Anoplophora glabripennis were studied. One generation occurred in Hohhot in two years. The mature larvae, the first instar larvae and the unhatched larvae can both wintering in the eggshell, and there were very few overwintering pupae. Adult saw it in late June, peaked in mid-July and reached mid-August in mid-August. The average female fecundity is 22 grains. The onset of eggs for the early July, the beginning of the peak for the first ten days of August, the peak for the late August, Sheng end of September early. The paper puts forward the method of predicting and forecasting the occurrence and the amount of occurrence is of practical value.
