温室粉虱 Trialeurodes vaporariorum Westwood 又名:菜剌粉虱、温室白粉虱,属粉虱科。据文献记载此虫发源于美洲,后传到欧洲,现已成为世界性害虫。我国南方各省早在五十年代就有为害。北京四季青公社1974年蔬菜产量曾因粉虱的危害减产40％左右。在我区1959年首先发现于银川市中山公园温室中,且已大量发生。1963年以后广泛发生于田间和居民家庭花卉上。塑料大棚里的蔬菜受害更为严重。目前此虫已遍及全区十多个县、市,成为园林植物一大害虫。我们于1981～82年就其生物学特性和药剂防治做了初步研究,现报告如下:一、银川地区发生概况及寄主范围此虫寄主很广,据报导可在23个目,84
Greenhouse whitefly Trialeurodes vaporariorum Westwood, also known as: food assassination whitefly, greenhouse whitefly, whitefly Division. According to the literature records of this worm originated in the Americas, after spread to Europe, has now become a worldwide pest. Provinces in southern China as early as the fifties have done harm. Beijing Sijiqing commune in 1974 vegetable production had whitefly hazards caused by about 40% reduction. In my area first discovered in 1959 in Yinchuan Zhongshan Park Greenhouse, and has occurred in large numbers. Occurred extensively in the fields and the flowers of the family after 1963. Vegetables in plastic sheds are even more devastating. At present, this insect has spread to more than 10 counties and cities in the region and has become a major pest of garden plants. We conducted a preliminary study on its biological characteristics and pesticide control in 1981-82, and are reported as follows: I. Overview and Host Range in Yinchuan This insect host is widely reported to be reported in 23 orders, 84
