摘要： 为了明确双斑长跗萤叶甲Monolepta hieroglyphica(Motschulsky)在谷田中的发生规律,并为该虫的预测预报和综合治理提供科学依据。[方法]2015年在山西省长治市的谷田中,用网捕法和直接观察法对双斑萤叶甲种群动态、垂直分布和有虫率进行了调查。[结果]调查结果为该虫成虫在7月份开始危害谷田；7月下旬到8月上旬,双斑萤叶甲种群数量急剧上升；8月中旬在谷子抽穗期和花期时成虫种群数量达到高峰；8月下旬随着谷子花期结束,双斑萤叶甲种群数开始大量迁出谷田。[结论]结果说明2015年双斑萤叶甲在山西长治地区谷田内爆发；其危害谷子的部位集中于谷穗上；通过相关性分析表明谷田中植株有虫率与该虫种群数量呈正相关。

Abstract: In order to determine the harm rules of Monolepta hieroglyphica (Motschulsky) in millet field, and provide scientific basis for forecasting and comprehensive treatment, the population dynamics, vertical distribution and worm rate of M. hieroglyphica were investigated in millet field in Changzhi, Shanxi in 2015 by the methods of net and observation. The results showed that Monolepta hieroglyphica began to endanger millet field at the beginning of July, and the population o Monolepta hieroglyphica increased dramatically during the late July to early August, and the population reached the maximum at the heading stage and flowering stage in the middle of August; with the finish of the flowering stage in late August, a large number of Monolepta hieroglyphica moved out of millet field. The results showed that there was a Monolepta hieroglyphica outbreak in millet field of Changzhi Shanxi in 2015, the main damaged part was icker. This study found that there was a positive correlation between worm rate and population quantity.
