| 摘 要： | 为探究黄瓜花叶病毒(Cucumber mosaic virus,CMV)、马铃薯Y病毒(Potato virus Y,PVY)混合侵染烟株对烟蚜取食行为的影响,利用刺探电位图谱(electrical penetration graph,EPG)技术记录了烟蚜在健康烟株与CMV、PVY混合侵染后不同发病级别烟株上的取食波形。结果显示:烟蚜在健康烟株上的刺探次数最少,在感病烟株上的C波总持续时间均显著长于健康烟株;第1次到达韧皮部前的刺探次数,健康植株上仅为4.00次,3级感病烟株上的为健康烟株上的2倍;在健康烟株上E2波总持续时间为120.65 min,极显著大于2级和3级感病烟株;刺探过程中,感病烟株上的pd波出现次数均高于健康烟株,且pd波II-1和II-3亚波的持续时间也显著高于健康烟株。研究表明,CMV、PVY混合侵染烟株可降低寄主对烟蚜的适合度,且能促进烟蚜对病毒的传播。

| Abstract: | To explore the effects of tobacco mixed infected by Cucumber mosaic virus (CMV) and Potato virus Y (PVY) on the feeding behavior of green peach aphid Myzus persicae (Sulzer), the feeding waveform of M. persicae on healthy and mixed infected tobaccos with different pathological grades were recorded by using electrical penetration graph technique. The results showed that the count probe times of M. persicae on healthy tobacco was the least among the different treatments. The total duration of C waveform of the infected tobacco was significantly longer than that of the healthy tobacco. Number of probes to the 1st saliva secretion on phloem level three infected tobacco was double that of healthy individuals. The duration in passive ingestion (E2 waveform) was 120.65 min on healthy plants, which was significantly longer than those of levels two and three infected plants. In the process of probe, the number of pd waveform of all infected plants was more than those of healthy tobaccos. The mean duration of pd II-2 and pd II-3 waveforms were also significantly increased. The results indicated that mixed infected tobacco could reduce the fitness of M. persicae and promote the aphid for virus transmission. |
