A field investigation was conducted on the spatial distributions of Sitobion avenae and its main natural enemies under wheat-oilseed rape intercropping and methyl salicylate application. With the development of wheat plant, an alternation from aggregation to uniform was observed in the spatial distribution of S. avenae under the intercropping and methyl salicylate application, being more obvious under the interaction of the two practices. The spatial distribution of S. avenae natural enemies was in accordance with that of the aphid. These results could be used for the reference of sampling investigation and forecast of wheat aphid and its natural enemies in field.
对小麦-油菜间作及水杨酸甲酯处理下麦长管蚜及其主要天敌的空间分布进行了田间调查。随着小麦植株的生长，在间作和水杨酸甲酯处理下，麦长管蚜的空间分布呈现出从聚集到均匀的转变，在两种处理方式的交互作用下更为明显。麦长管蚜天敌的空间分布与蚜虫一致。这些结果可为田间麦蚜及其天敌的抽样调查和预测提供参考。
