摘　　要：通过对武汉地区棚栽早熟西瓜节肢动物群落的研究,旨在阐明其群落结构的组成及特点,为棚栽早熟西瓜害虫的无害化防治提供科学依据。通过2009年对武汉地区棚栽早熟西瓜田节肢动物群落的实地调查和分析,共获得节肢动物102种,分属于3纲,12目,55科,其中植食类36种(国内新纪录1种),捕食类37种,寄生类10种和其他类19种,种类数分别占总群落的35.29%、36.27%、9.80%、18.63%;优势度指数分别为:0.436812、0.272140、0.040924和0.250124。早熟棚栽西瓜田节肢动物群落可划分为4个营养层,6个功能团和22个类群,瓜蚜Aphis gossypii Glover和瓜亮蓟马Thrips flavus Schrank是有害节肢动物中的优势种,为防治的重点对象。The study of arthropods community on early mature watermelon in the greenhouse aimed to illustrate the composition and characteristic of their community structure and provided scientific basis for harmless prevention and control of pests in the fields of early mature watermelon.The investigation and analysis of arthropods on early mature watermelon in the greenhouse were carried out in 2009 in Wuhan.The results showed that the arthropod communities on early mature watermelon in the greenhouse consisted of 3 classes,12 orders,55 families,102 species.Among them,there are 36 species of phytophage（one kind of phytophage is domestic new record）,37 species of predators,10 species of parasitoids and the other 19 species.The species numbers of the four groups account for 35.29%,36.27%,9.80%,18.63% respectively,and the dominance indexes of the four groups were 0.436812,0.272140,0.040924,and 0.250124 respectively.All of the arthropods could be divided into 4 nutrient classes,6 guilds and 22 groups.Thrips flavus Schrank and Aphis gossypii Glove were the dominant species of the arthropod pests;they were the major insect pests on early mature watermelon in the greenhouse to be controled.
