摘　　要：悬铃木方翅网蝽Corythucha ciliata(Say)是近年来悬铃木Platanus spp.上严重发生的害虫之一。采用6个聚集度指标和Taylor幂函数法则、Iwao的线性回归分析法、兰星平的La-m回归模型及m-V模型4个回归模型对悬铃木方翅网蝽在悬铃木上的空间分布型进行测定。结果表明:悬铃木方翅网蝽成虫、若虫和整个种群均呈聚集分布,个体间相互吸引,分布的个体成分是个体群,其分布与密度有关,密度越大聚集程度越强。虫口密度在4.3头/叶以下时,聚集原因是由环境因素引起的;虫口密度大于4.3头/叶时,聚集原因是由悬铃木方翅网蝽自身行为或环境因素引起的。并建立了理论抽样数公式。Corythucha ciliata has become a serious pest for Platanus spp. in recent years. The spatial distribution pattern of C. ciliata adults,nymphs and population was determined by six spatial distribution pattern indices,Taylor＇s regression model,lwao＇ s regression equation,Lan-Xingping＇ s La-m and m-V regression analysis. The results indicated that C. ciliata adults,nymphs and the whole population showed aggregation distribution,and the individuals attracted each other. The basic unit of distribution was individual groups. Its distribution was related to population density. The greater the population density was,the stronger the aggregation degree was. It can be concluded that aggregation was influenced by pests behavior and environment condition when the number of insects on each leaf was more than 4. 3,and it was influenced by environment condition if the number of insects on each leaf was less than 4. 3. The formula of theoretical sampling number for C. ciliata was established.
