摘　　要：通过2004-2006年3年的调查,初步探明江苏沿海城市市区烟粉虱Bemisia tabaci(Gennadius)种群的适生寄主多达300余种,包括农作物47种,园林树木74种,水果林木8种,花卉60种,中药材17种,草坪草5种,杂草近百种,其中尤以锦葵科、茄科、菊科植物发生量大,危害重。市区烟粉虱的虫源性质为:多种适生寄主有利于成虫在市区"安家落户";特殊气侯条件导致虫源多次蔓延扩散而暴发;Q型生物种为市区成虫大发生的优势种群;市区烟粉虱成虫大发生的虫源主要来自于棉花;早春越冬大棚防治不彻底成为市区烟粉虱暴发的原始虫源。From 2004 to 2006, 300 hosts of Bemisia tabaci were initially proved, involving 47 crops, 74 garden trees, 8 fruit trees, 60 flowers, 17 Chinese medicinal materials, 5 turf grasses and over 100 weeds, especially worse in the Malvaceae, Solanaceae and Compositae. The main reasons why Bemisia tabaci population happened in cities were that many hosts suited Bemisia tabaci; special climate caused them to disperse and outbreak; the type Q turned the dominant species; B. tabaci adults originated from cottons, and the population controlled incompletely in greenhouses in the early spring would become the initial population in cities.
