摘要: 用EPG记录法记录了大豆蚜Aphis glycines Matsunra在寄主和非寄主植物上的口针刺吸行为。结果表明,大豆蚜在寄主大豆植物的韧皮部取食时间长,而在非寄主棉花、黄瓜和丝瓜植物韧皮部取食时间甚短或根本未取食;非寄主植物内部对大豆蚜的侵害存在抗性,影响取食的因素和其所在部位因非寄主植物种类的不同而不同。

Abstract: The stylet penetration and suck behaviour of soybean aphid, Aphis glycines Mat., on host and non-host plants was monitored by using an electrically recording method (EPG). The results showe4 that phloem ingestion was reduced or did not happen on the non-host plants, Gossypium hirsutum, Cucumis sativa andLuria cylindrica, when compared with that on the host plant, Glycines max. The non-host plants possess resistance against A. glycines. And with the difference of the non host plants, the factors affecting ingestion and their position on the plant were different.

Key words: Aphis glycines, piercing-sucking mouthparts, feeding behaviour, host plant selection, EPG technique
