《环境昆虫学报》

本文明确了河北省粉虱种类、分布及其携带番茄黄化曲叶病毒（Tomato yellow leaf curl virus，TYLCV）情况。在河北省11市33县不同蔬菜瓜果类作物上采集了91份粉虱样本，利用mtDNA COⅠ基因和番茄黄化曲叶病毒AC3基因，鉴定粉虱种类及其是否携带TYLCV，分析粉虱在不同寄主作物及地理区域内的分布情况。在采集的91份粉虱样本中，4份为温室白粉虱Trialeurodes vaporariorum均在张家口，其中张家口蔚县茄子上的温室白粉虱携带TYLCV；87份为烟粉虱Bemisia tabaci均属于MED隐种，分布在11个地区（邯郸、邢台、石家庄、衡水、沧州、保定、廊坊、唐山、秦皇岛、承德、张家口）29个采集地点，其中39份样本检测到TYLCV；沧州市样本携带TYLCV的烟粉虱MED隐种占比最多（87.5%），其次为唐山市、石家庄市和衡水市样本（携毒率均为55.5%），秦皇岛市样本携毒率最少（11.1%）。本研究可为河北省粉虱及番茄黄化曲叶病毒病的预报预测和科学防控提供理论依据。

英文摘要:

This study aimed to identity the species, distribution and Tomato yellow leaf curl virus (TYLCV) carriage status of whiteflies in Hebei Province. A total of 91 whitefly samples were collected from various vegetable and fruit crops across 33 counties in 11 cities in Hebei Province. The mtDNA COⅠ gene and TYLCV AC3 gene were utilized to identify whitefly species and whether they carried TYLCV, and the distribution patterns of whiteflies across different host crops and geographical regions were analyzed. Among the 91 whitefly samples collected, 4 were identified as Trialeurodes vaporariorum, all found in Zhangjiakou, and among them, the T. vaporariorum on eggplants in Yu County (Zhangjiakou) carried TYLCV. The remaining 87 whitefly samples were identified as Bemisia tabaci，all belonging to the MED cryptic species, distributed across 29 collection sites in 11 regions (Handan, Xingtai, Shijiazhuang, Hengshui, Cangzhou, Baoding, Langfang, Tangshan, Qinhuangdao, Chengde, and Zhangjiakou). Among these, 39 samples were detected with TYLCV. B. tabaci MED cryptic species from Cangzhou exhibited the highest TYLCV carrying proportion (87.5%), followed by the samples from Tangshan, Shijiazhuang and Hengshui (all 55.5%), while Qinghuangdao showed the lowest infection rate (11.1%). This study can provide a theoretical basis for forecasting, prediction and scientific control of whitefly and TYLCV diseases in Hebei Province.
