麦长管蚜(Macrosiphum avenae Fab.)系北京麦田蚜虫的主要种群。近10余年,随着京郊小麦生产水平的提高,麦蚜危害日益猖獗,已上升为小麦的丰要害虫。但人们对麦蚜危害的认识不一,在制订防治指标和防治措施上缺乏科学依据。为了测定麦蚜危害造成的损失、制订科学的防治指标,我们对麦蚜危害产量损失进行了研究。现将试验结果报道如下。
Macrosiphum avenae Fab. Is the main aphid in Beijing wheat field. In the past 10 years, with the improvement of the wheat production level in the suburbs of Beijing, the harm of the wheat aphid has become increasingly rampant and has risen to the abundance of pests of wheat. However, people have different understandings on the harm of wheat aphids, and there is no scientific basis for formulating prevention and control measures and prevention and control measures. In order to determine the damage caused by the harm of wheat aphid and formulate scientific control indicators, we studied the harm of wheat aphid to the loss of yield. The test results are reported below.
