植物病毒可以改变寄主植物的表型和防御途径及其载体的性能，从而促进它们的传播。南瓜褪绿质黄化病毒(CCYV)(CriniVirus)是一种新发现的发生在葫芦科植物和其他植物上的病毒，由B型烟粉虱MEAM1和Q型潜伏种MED以半持久性方式传播。本研究评估了CCYV对烟粉虱的影响，以更好地了解植物-病毒-媒介的相互作用。通过使用CCYV-B。Tabaci MED-黄瓜为模型，我们调查了半持久性植物病毒是否或如何影响其烟粉虱媒介的生物学。在烟粉虱1~4龄若虫和成虫体内均可检测到CCYV mRNAs，且滴度不同。在感染CCYV的植株上，雌性粉虱若虫的龄期和成虫寿命显著延长，而雄性粉虱的若虫龄期和成虫寿命没有显著影响。取食CCYV感染植株的成虫体长和产卵量增加，但不影响卵的孵化率和不同时期的成虫存活率。最有趣的是，在感染CCYV的植物上，烟粉虱种群的性别比(雄性：雌性)显著降低到0.5：1，而在健康植物上，这一比例保持在1：1左右。这些结果表明，CCYV对其载体烟粉虱的生物学特性有显著影响。推测CCYV与烟粉虱在寄主植物的介导下已建立起典型的互惠关系。
Plant viruses can change the phenotypes and defense pathways of the host plants and the performance of their vectors to facilitate their transmission. Cucurbit chlorotic yellows virus (CCYV) (Crinivirus), a newly reported virus occurring on cucurbit plants and many other plant species, is transmitted specifically by Bemisia tabaci MEAM1 (B biotype) and MED (Q biotype) cryptic species in a semipersistent manner. This study evaluated the impacts of CCYV on B. tabaci to better understand the plant-virus-vector interactions. By using CCYV-B. tabaci MED-cucumber as the model, we investigated whether or how a semipersistent plant virus impacts the biology of its whitefly vector. CCYV mRNAs were detectable in nymphs from first to fourth instars and adults of B. tabaci with different titers. Nymph instar durations and adult longevity of female whiteflies greatly extended on CCYV-infected plants, but nymph instar durations and adult longevity of male whiteflies were not significantly influenced. In addition, the body length and oviposition increased in adults feeding on CCYV-infected plants, but the hatching rates of eggs and survival rates of different stages were not affected. Most interestingly, the sex ratio (male:female) significantly reduced to 0.5:1 in whitefly populations on CCYV-infected plants, while the ratio remained about 1:1 on healthy plants. These results indicated that CCYV can significantly impact the biological characteristics of its vector B. tabaci. It is speculated that CCYV and B. tabaci have established a typical mutualist relationship mediated by host plants.
