摘  要：
近年来,随着全球气候变化和我国农作物种植结构调整,粘虫在我国的发生危害呈现出新的特点。为明确济宁地区麦田中越冬代和1代粘虫的发生规律及科学指导新形势下该地区粘虫的防治,本研究采用佳多自动虫情测报灯监测了越冬代和1代粘虫的种群发生动态。结果显示,2015和2016年诱集的成虫总蛾量分别为249头和62头,2016年4月9日即可诱到极少量越冬代成虫,1代成虫的发生高峰期约为6月上旬左右,两年的单日最大蛾量分别为47头和13头。此外,田间条件下采用人工接虫和笼罩法测定了粘虫不同虫口密度危害对小麦产量的影响,建立了小麦产量损失率与虫口密度的线性回归方程,并根据当前条件下小麦的生产水平和市场价格,确定济宁地区麦田粘虫的防治指标以26头/m2为宜。

摘  要：
Recently,as the global climate change and crop planting structure adjustment in China,the occurrence and damage of Mythimna separate present new characteristics. In order to clarify the population regularity of M. separate and guild the control of this pest in winter wheat fields in Jining district in the new situation,we used light trap to monitor the population dynamics of overwintering generation and the 1 st generation of M. separate. The results showed that the total number of trapped adults in 2015 and 2016 was 249 and62,respectively. On April 9 of 2016,the adults of overwintering generation appeared,although the amount was very tiny. The peak of 1 st generation population appeared at around early June each year and the daily maximum moth was 47 and 13,respectively. In addition,we also established the linear relationships between the percentage of wheat yield loss and pest density by using artificial inoculation and caging under field conditions. Based on the current wheat production level and market price,the economic threshold of M. separate was 26 per square meter in Jining district.
