中文摘要: |
番茄褪绿病毒 Tomato chlorosis virus (ToCV)对我国番茄种植业破坏极大, 而粉虱类昆虫是其主要传播介体。本研究调查了我国内蒙古自治区赤峰市和贵州省贵阳市的番茄褪绿病毒病发生情况, 发现赤峰市的发病率为73.3%, 贵阳市的发病率为53.3%。两个地区均存在Q型烟粉虱和温室白粉虱, 赤峰市的Q型烟粉虱和温室白粉虱分别占75.9%和24.1%; 贵阳市的Q型烟粉虱和温室白粉虱分别占39.8%和60.2%。对两个地区的两种粉虱种群在室内进行传毒特性研究,结果发现, 经过48 h获毒后Q型烟粉虱和温室白粉虱的获毒量没有明显差异, 但无论1头或10头粉虱, Q型烟粉虱的传毒量都高于温室白粉虱。结果说明, 近年来随着Q型烟粉虱发生的日益严重, 番茄褪绿病毒通过Q型烟粉虱的传播值得人们重视和进一步研究。 |
英文摘要: |
Tomato chlorosis virus (ToCV) is extremely destructive to tomato planting in China, and whitefly insects are the main vectors to transmit ToCV. In this study, we investigated the occurrence of Tomato chlorotic virus disease in Chifeng, Inner Mongolia, and Guiyang, Guizhou province. The disease incidence in Chifeng was 73.3%, and that in Guiyang was 53.3%. Bemisia tabaci Q and Trialeurodes vaporariorum were detected in both areas, and the proportions of B. tabaci Q and T. vaporariorum in Chifeng were 75.9% and 24.1%, respectively, while thosein Guiyang were 39.8% and 60.2%, respectively. Then samples of whitefly from two regions were collected and the characteristics of the virus transmission were investigated in our laboratory. The results showed that there was no significant difference in the acquisition amount of B. tabaci Q and T. vaporariorum after 48 h of virus acquisition. However, regardless of 1 or 10 whiteflies, the transmission amount of B. tabaci Q was higher than that of T. vaporariorum. The results indicated that with the increasing occurrence of B. tabaci Q in recent years, the spread of Tomato chlorotic virus through B. tabaci Q is worthy of more attention and further study. |
