The feeding behaviour of cotton aphid, Aphis gossypii Glover, on different cotton varieties was tested by EPG ( Electrical Penetration Graph(EPG) ), six basic patterns of feeding behaviour were recorded. 应用电动穿刺记录技术(EPG)对棉蚜在不同棉花品种上的取食行为进行了测定,结果记录到棉蚜的6种取食行为基本波型。
The simultaneous display technique of electrical penetration graph ( EPG ) was used to study the effects of the wave potential drop ( pd ) and its sub-phases in the acquisition of cucumber mosaic virus ( CMV ) by the cotton aphid Aphis gossypii from the infected melon plants. 利用刺吸电位(EPG)及其即时中断技术研究了棉蚜Aphisgossypii传播黄瓜花叶病毒(CMV)的机理,分析电势落差波(pd)及其亚波形在棉蚜获得CMV的取食行为过程中的作用。
