Ozone (O) is a major air pollutant that has a profound effect on whole ecosystems. In this study we studied how hO3 affected the transmission of the Tomato yellow leaf curl China virus (TYLCCNV), a begomovirus, by the Q biotype Bemisia tabaci in a persistent, circulative manner. We found hO3 affected the transmission of TYLCCNV via the effect of it on the microbial community of the transmitting insect, such as Candidatus Hamiltonella, Ralstonia, Diaphorobacter, Caldilineaceae, Deinococcus, Rickettsia, Thysanophora penicillioides and Wallemia ichthyophaga. We concluded that hO decreased the resistance of acquiring virus tomatoes, and decreased the immune response and increased the endurance to extreme environments of viruliferous whiteflies by altering the composition and abundance of the microbial environments inside the body and on the surface of whitefly, as a result, it enhanced the TYLCV transmission rate by the Q biotype whitefly.
臭氧（O）是一种主要的空气污染物，对整个生态系统有深远的影响。在这项研究中，我们研究了高臭氧（hO3）如何通过持久性、循环性方式影响 Q 型烟粉虱对番茄黄曲叶病毒（TYLCCNV）的传播。我们发现 hO3 通过影响传毒昆虫的微生物群落，如 Hamiltonella、Ralstonia、Diaphorobacter、Caldilineaceae、Deinococcus、Rickettsia、Thysanophora penicillioides 和 Wallemia ichthyophaga，从而影响 TYLCCNV 的传播。我们得出结论，hO3 通过改变烟粉虱体内和体表微生物环境的组成和丰度，降低了感病番茄获得病毒的抗性，降低了免疫反应，增加了对极端环境的耐受能力，从而增强了 Q 型烟粉虱对 TYLCV 的传播率。
