烟粉虱Bemisia tabaci(Gennadius)是一种入侵能力强、环境适应性高和危害严重的世界性害虫之一。本文调查了温室中12种栽培植物上烟粉虱的发生情况。结果表明,9种植物上有烟粉虱的危害,按照危害严重程度排列为非洲菊、一品红>黄瓜、番茄、辣椒、茄子>马蹄莲、茼蒿、皱叶莴苣,其余3种植物紫背天葵、朱顶红、荷兰铁上未查到烟粉虱危害。非洲菊的整个生育期都有烟粉虱发生,其中6月下旬~7月初和10月上旬是烟粉虱在温室非洲菊上的两个危害高峰期。聚集度指标测定表明,烟粉虱在温室内非洲菊植株上属于聚集分布,分布的基本成分是个群体。
Bemisia tabaci (Gennadius) is one of the most invasive pests in the world with high invasiveness, high environmental adaptability and serious harm. This paper investigated the occurrence of whitefly on 12 cultivated plants in a greenhouse. The results showed that the harmful effects of B. tabaci on nine plants were classified as gerbera, poinsettia, cucumber, tomato, peppers, eggplant, calla lily, Artemisia selengensis and curly lettuce, and the remaining three plants, , Hippeastrum, the Netherlands did not detect the whitefly on the iron hazards. Bemisia tabaci throughout the growing period of whitefly occurred, of which late June ~ early July and early October is the whitefly on greenhouse gerbera two hazardous peak. Aggregation index measurements show that Bemisia tabaci belong to the aggregation distribution in the greenhouse Gerbera plants, the distribution of the basic component is a group.
