中文摘要：  B型和Q型烟粉虱已通过病毒传播造成作物和蔬菜严重损失。之前的研究表明，Q型烟粉虱在获得和传播番茄黄化曲叶病毒（TYLCV）方面比B型烟粉虱更有效，并且在反击茉莉酸（JA）介导的植物防御方面带毒Q型烟粉虱比B型更胜一筹。为了解植物介导的包括JA在内的防御响应如何影响植物、昆虫和病毒三元框架内的昆虫介体，本研究了外源JA对不带毒和带毒B型和Q型烟粉虱在番茄植株上的偏好与表现的影响。研究结果表明，相对于对照植株而言，经JA处理过的番茄上粉虱的繁殖力明显降低，寿命和发育周期明显缩短，存活率降低。另外，在繁殖力、寿命、发育周期和存活率方面，带毒Q型烟粉虱显著好于B型。值得注意的是，Q型烟粉虱与TYLCV之间存在着一种互惠共生关系以抵抗寄主防御。更好地了解植物、昆虫和病毒之间的关系，将有助于这种入侵性的全球性害虫可持续管理的发展。
外文摘要：The sweetpotato whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), B and Q biotypes have caused severe losses to crops and vegetables through virus transmission. Our previous studies showed that Q is more efficient than B in acquisition and transmission of tomato yellow leaf curl virus (TYLCV) and viruliferous Q is better equipped than B in counterattacking jasmonic acid (JA)-related plant defense. To understand how plant-mediated defensive responses involving JA affect insect vectors within a tritrophic framework of plants, insects, and viruses, we examined the effects of exogenous JA on preference and performance of non-viruliferous and viruliferous B and Q on tomato plants (Solanum lycopersicum L., Solanaceae). Our results demonstrated a significantly lower fecundity, shorter longevity, shorter developmental time, and lower survival rate of whiteflies on JA-treated than on control plants. In addition, viruliferous Q performed significantly better than B in fecundity, longevity, developmental time, and survival rate. When given a choice between JA-treated and control tomato plants, viruliferous Q was not repelled to JA-treated plants when the JA concentration was 0.01 and 0.1mm, whereas others all preferred the untreated control plants. Exogenous JA increased the concentration and the composition of plant volatiles, such as -terpinene and -ocimene, which deterred whiteflies in a Y-tube bioassay. It is worth noting that Q has a mutualistic relationship with TYLCV to counteract the host defenses. A better understanding of tritrophic interactions between plants, insects, and viruses will facilitate the development of sustainable management of this invasive global pest.
