Result Observations on five host plants revealed that four waveforms correlated with feeding behavior:Ⅰrepresents stylet thrusting into plant tissue, Ⅱ represents multiple-cell laceration and salivation, Ⅲ represents ingestion, and Ⅳ represents withdrawal of the stylet from the plant tissue.
结果中黑盲蝽在各寄主上的刺探电位波形由Ⅰ波、Ⅱ波、Ⅲ波和Ⅳ波4部分组成。 Ⅰ波表示口针的刺入;Ⅱ波表示口针在撕裂植物组织和细胞,并向外分泌唾液;Ⅲ波表示取食;Ⅳ波表示口针的拔出。

一旦口针进入韧皮部持续吸食阶段，蚜虫在三个部位的取食行为没有太大的差异。
And no significant differences were found in feeding behaviors among aphids on three plant parts once sustained ingestion started in the phloem.
与CK非洲E40相比，多毛可以显著降低棉蚜的取食周期E2，并可显著延长第1非取食周期和增加蚜虫口针的刺探频率。
As compared with CK (var. African E40) , the density of hairiness reduced the feeding time E2, and increased the 1st non-feeding time and penetration frequency.
不同寄主上棉蚜的口针长度表现为棉花、黄瓜>甜瓜、木槿，棉花和黄瓜上棉蚜不能相互转接不是由于棉蚜口针长度差异所致。
The stylet length of cotton aphid living on cucumber and cotton host had no significant difference, so it was not the cause of the host preference.
