中文摘要:植物病毒可以改变它们介体的表现行为是已众所周知的。然而,一种半持久性植物病毒是否或者如何操纵其粉虱介体的取食行为还未见有研究报道。瓜类褪绿黄化病毒(CCYV)是许多亚洲国家一种紧急的植物病毒,经由B型和Q型烟粉虱以半持久性方式传播。本文通过刺探电位图谱(EPG)技术研究了CCYV对烟粉虱取食行为的影响。结果显示,CCYV均不同程度地改变了不同生物型和性别烟粉虱的取食行为。研究结果表明,在携带传播CCYV的过程中,Q型烟粉虱的作用大于B型烟粉虱,雄性烟粉虱的贡献大于雌性烟粉虱。
外文摘要:It is known that plant viruses can change the performance of their vectors. However, there have been no reports on whether or how a semipersistent plant virus manipulates the feeding behaviors of its whitefly vectors. Cucurbit chlorotic yellows virus (CCYV) (genus Crinivirus, family Closteroviridae) is an emergent plant virus in many Asian countries and is transmitted specifically by B and Q biotypes of tobacco whitefly, Bemisia tabaci (Gennadius), in a semipersistent manner. In the present study, we used electrical penetration graph (EPG) technique to investigate the effect of CCYV on the feeding behaviors of B. tabaci. The results showed that CCYV altered feeding behaviors of both biotypes and sexes of B. tabaci with different degrees. CCYV had stronger effects on feeding behaviors of Q biotype than those of B biotype, by increasing duration of phloem salivation and sap ingestion, and could differentially manipulate feeding behaviors of males and females in both biotype whiteflies, with more phloem ingestion in Q biotype males and more non-phloem probing in B biotype males than their respective females. With regard to feeding behaviors related to virus transmission, these results indicated that, when carrying CCYV, B. tabaci Q biotype plays more roles than B biotype, and males make greater contribution than females.
