摘 要：
【目的】通过对核桃小麦间作田、红枣小麦间作田及小麦单作田麦长管蚜的种群动态研究,探讨果麦间作模式下麦田麦长管蚜的发生危害特点及与小麦单作田的差异性。【方法】采用定期定点调查与抽样调查相结合的方法,研究核桃小麦间作田、红枣小麦间作田和小麦单作田麦长管蚜种群动态。【结果】麦长管蚜5月上中旬开始危害,核桃小麦间作田发生危害时间稍早于红枣小麦间作田和小麦单作田;果麦间作模式下麦田麦长管蚜田间消长规律与小麦单作田基本一致,危害高峰在5月下旬到6月上旬;核桃小麦间作田麦长管蚜发生量大于红枣小麦间作田和小麦单作田麦长管蚜发生量。【结论】核桃小麦间作麦田、红枣小麦间作麦田和小麦单作田麦长管蚜的田间消长规律基本一致;麦长管蚜在核桃小麦间作田的危害重于其在红枣小麦间作田和小麦单作田的危害。

摘 要：
【Objective】Through the research on the population dynamics of sitobion avenae in wheat fields of walnut-wheat intercropping or jujube-wheat intercropping or wheat monoculture,we discussed the effects of fruit tree-wheat intercropping mode to sitobion avenae.【Method】By regular fixed-point investigation and sample investigation,the amount of sitobion avenae in wheat field of Walnut-wheat intercropping or jujube-wheat intercropping or wheat monoculture was investigated.【Result】Results showed that sitobion avenae began to harm in early May,and the appearance of sitobion avenae in wheat field of walnut-wheat intercropping was earlier than jujube-wheat intercropping and wheat monoculture. The amount of sitobion avenae in wheat field of walnut-wheat intercropping was more than jujube-wheat intercropping and wheat monoculture. The population dynamics of sitobion avenae in wheat fields of fruit tree-wheat intercropping and wheatmonoculture were basically consistent. Sitobion avenae damage peaked in early June.【Conclusion】The population dynamics of sitobion avenae in wheat fields of fruit tree-wheat intercropping and wheat monoculture was basically consistent. Sitobion avenae in wheat field of walnut-wheat intercropping was more harmful than jujube-wheat intercropping and wheat monoculture.
