摘要: 为进一步了解雄安新区及其周边地区烟粉虱的生物型及其种群发生为害动态,分别于2016和2017年对雄安新区及其周边5个县级辖区的烟粉虱的生物型(隐种)、种群动态和空间分布格局进行了调查研究。结果表明:目前该地区主要蔬菜作物上发生的烟粉虱均为Q型(MED隐种)烟粉虱;整个调查期间,均发现烟粉虱发生为害情况,不同寄主植物上烟粉虱种群动态不同,每年9月中下旬,烟粉虱在茄子和棉花上的种群密度都有不同程度的回升;绝大多数情况下,烟粉虱在寄主植物上属聚集分布。上述研究结果为烟粉虱的预测预报和防治策略的制定提供了理论依据。

Abstract: To better understand the bio-type and population dynamics of Bemisia tabaci in Xiongan new area and its surrounding areas, this paper investigated bio-type (cryptic species), population dynamics and spatial distribution of this pest in Xiongan new area and its surrounding five counties in 2016 and 2017. Results showed that: The dominant bio-type of B. tabaci in this area changed from bio-type B (cryptic species MEAM1) to bio-type Q (cryptic species MED); it occurred during the whole investigation period, but population dynamics differed among the host plants. Population densities of B. tabaci on eggplant and cotton increased at different levels in late September every year; B. tabaci were aggregated distribution in most cases. These results provided theoretical foundation for the forecast and controlling strategies formulation of B. tabaci.
