中文摘要:烟粉虱是许多植物病毒的重要载体,包括紧急半永久传播的毛形病毒属番茄褪绿病毒(ToCV)。病毒介体的取食行为比较复杂,对病毒的传播、流行和控制具有重要的意义。因此,本研究的目的是利用电位图(EPG)技术探讨烟粉虱刺吸渗透行为在番茄ToCV接种中的作用。EPG记录根据观察到的波形分为六个级别。研究结果表明,ToCV接种主要与烟粉虱在韧皮部筛管处(E-1 waveform)的刺吸行为有关,当烟粉虱进行E-1 waveform阶段时传输率明显增加。
外文摘要:Bemisiatabaci is an important vector of numerous plant viruses, including the emergent semi-persistently transmitted crinivirus Tomato chlorosis virus (ToCV). Its vector feeding behaviour is complex, with important implications for virus transmission, epidemiology and control. Thus, the objective of this study was to investigate the role of the stylet penetration activities of B. tabaci in the inoculation of ToCV in tomatoes by using the electrical penetration graph (EPG) technique. EPG recordings were classified into six categories depending on the waveforms observed. The results showed that ToCV inoculation is mainly associated with stylet activities in phloem sieve elements (E-1 waveform), as there was a significant increase in the rate of transmission when whiteflies performed waveform E-1. The precise stylet activities either salivation or egestion associated with virion release, presumably from retention sites in the foregut, need further investigation.
