摘要
通过2007~2010年连续调查发现烟粉虱[Bemisia tabaci （Gennadius）]在湖北省露地能安全越冬，并成为翌年春季虫源基数的一部分。主要越冬寄主有荔枝草（Saluia plebeia R. Br.）、小飞蓬[Conyza Canadensis （L.）Cronq.]、一年蓬（Erigeron annuus）、益母草（Leonurus heterophyllus Sweet）、苦苣菜（Sonchus oleraceus L.）、马蹄金（Dichondra micranrtha Urban）、金银花（Lonieera japonica Thunb.）等。越冬虫态主要是卵和伪蛹，冬后虫量与前一年烟粉虱的发生量相关。
Based on the 3-year continuous surveies from 2007 to 2009, B. tabaci was found to be the main source of insect pest in the following year and could overwinter on some weeds and flowers including AIternanthera philoxeroides,Conyza Canadensis,Erigeron annuus,Leonurus heterophyllus, Sonchus oleraceus,Dichondra micranrtha and Lonieera japonica etc in open field in Hubei province. The overwintering amount of B.tabaci was related with the occurring quantity in winter.
