中文摘要：烟粉虱是病毒传播介体，可造成全球园艺和观赏作物严重受损。在意大利，MED和MEAM1烟粉虱隐种广泛分布于西西里岛和撒丁岛等南部地区。过去的二十年中，在这些实施集约化农业发展的地区MED种群日渐增多。最近传入的菜豆金黄花叶病毒属新德里番茄曲叶病毒（ToLCNDV）引发了病毒传播介体和有症状植株的普查。2016年和2017年在拉齐奥地区（意大利中部）开展了监测，该地区此前从未发生过菜豆金黄花叶病毒属病毒感染，且认为B型烟粉虱的出现只是偶然现象。调查结果表明，烟粉虱已在拉齐奥地区建立，这使得ToLCNDV有可能扩散到该地区的其他地方以及附近具有相似气候和栽培条件的意大利中部地区。烟粉虱向北传播是病毒病流行病学和意大利中部由烟粉虱传播的病毒管理的一个关键问题，必须严格监控。
外文摘要：Bemisia tabaci (Hemiptera: Aleyrodidae) is responsible for severe damage to horticultural and ornamental crops worldwide, mainly for its role as virus vector. In Italy, the B. tabaci Mediterranean (MED) and Middle East-Asia Minor 1 (MEAM1) cryptic species are widespread in the Southern regions as well as in Sicily and Sardinia. During the last two decades, MED populations progressively increased, in those areas where intensive farming is applied. The recent introduction of the begomovirus Tomato leaf curl New Delhi virus (ToLCNDV) prompted extensive surveys of both vector and symptomatic plants. In 2016 and 2017, monitoring activities were carried out in Lazio region (Central Italy) where begomovirus epidemics had never occurred before and the presence of B. tabaci was thought to be only occasional. ToLCNDV-infected zucchini plants were found in Southern Lazio together with whitefly populations belonging only to the MED cryptic species. The MED-Q2 haplotype was the most abundant, likely favored by high temperatures and intensive agricultural practices. Single and mixed populations of MED and MEAM1 were found in Central and Northern Lazio, suggesting that agro-ecological factors still limit MED outbreaks in these areas. This preliminary survey indicates that B. tabaci is well established in Lazio, making ToLCNDV potentially able to spread to the rest of the region as well as to the nearby regions of Central Italy that have similar climatic and cultural conditions. The northward spread of B. tabaci is a critical issue for viral disease epidemiology and the management of whitefly-transmitted viruses in Central Italy, and must be kept under strict surveillance.
