Abstract

Virus infections cause economic losses in crops worldwide and their management and control present major challenges. In the field, double infections of two or more viruses are the rule, not the exception. The presence of several viruses in a plant makes it difficult to interpret virus-insect vector-plant interactions. Mixed infections can alter plant symptoms compared with single infections and may also impact their vectors. We describe plant-mediated indirect effects of virus double-infection on feeding behavior of an aphid vector (Aphis gossypii Glover) and virus transmission in melon (Cucumis melo L.). The viruses we used were a circulative cucurbit aphid-borne yellows virus (CABYV, Solemoviridae:Polerovirus) and a non-circulative cucumber mosaic virus (CMV, Bromoviridae:Cucumovirus). When melon plants were CMV-infected, indirect plant-mediated effects on A. gossypii feeding were like those reported on other plant species; specifically, intracellular punctures (pd) were more frequent and longer than on mock-inoculated plants, which enhanced CMV transmission. Similarly, when plants were CABYV-infected, we observed a statistically non-significant trend for increases in extended salivation (E1) and ingestion (E2) activities in phloem compared with mock-inoculated plants, which also enhanced CABYV transmission. When aphids fed on CMV-CABYV double-infected plants feeding behavior activities related to the transmission of both viruses were enhanced even more than when feeding on single-infected plants. Nevertheless, the virus transmission rate was the same on single-infected or double-infected plants. Thus, our results suggest that double infections do not modify viral dispersion compared with single infections since the indirect effect of CMV and CABYV in single infections is already optimized to favor virus transmission.

棉蚜(半翅目:蚜科)对甜瓜双重病毒感染的摄食反应。
病毒感染给世界各地的作物造成经济损失,其管理和控制提出了重大挑战。在该领域,两种或两种以上病毒的双重感染是普遍现象,而不是例外。由于植物中存在多种病毒,因此很难解释病毒-昆虫媒介-植物之间的相互作用。与单一感染相比,混合感染可改变植物症状,也可能影响其媒介。我们描述了植物介导的病毒双重感染对蚜虫(棉蚜)取食行为和病毒在甜瓜(Cucumis melo L.)中的传播的间接影响。我们使用的病毒是一种循环黄瓜蚜传播的黄病毒(CABYV, solemoridae:Polerovirus)和一种非循环黄瓜花叶病毒(CMV, Bromoviridae:Cucumovirus)。当cmv侵染甜瓜植株时,棉蚜取食受到植物间接介导的影响与其他植物相似;具体而言,细胞内穿刺(pd)比模拟接种的植物更频繁和更长,这增强了CMV的传播。同样,当植物感染CABYV时,我们观察到韧皮部延伸唾液(E1)和摄食(E2)活性与模拟接种的植物相比有统计学上不显著的增加趋势,这也增强了CABYV的传播。当蚜虫以CMV-CABYV双感染植物为食时,与两种病毒传播相关的摄食行为活性比以单感染植物为食时更强。然而,病毒在单侵染和双侵染植株上的传播率是相同的。因此,我们的研究结果表明,与单次感染相比,双重感染不会改变病毒的扩散,因为CMV和CABYV在单次感染中的间接作用已经优化为有利于病毒传播。

期刊介绍: The Journal of Insect Science was founded with support from the University of Arizona library in 2001 by Dr. Henry Hagedorn, who served as editor-in-chief until his death in January 2014. The Entomological Society of America was very pleased to add the Journal of Insect Science to its publishing portfolio in 2014. The fully open access journal publishes papers in all aspects of the biology of insects and other arthropods from the molecular to the ecological, and their agricultural and medical impact.
