摘　　要：对双斑长跗萤叶甲成虫的空间分布型进行了测定,结果表明,成虫符合负二项分布,聚集度指标检验成虫为聚集分布,聚集原因是由外界环境引起的;并建立了成虫在棉田中的理论抽样数学模型,田间随机取样适宜选用平行线、棋盘式和“Z”字型。It was measured to spatial distribution pattern for the adults of Monolepta hieroglyphica. The results showed that it belongs to the negative binomial distribution and it falls under the pattem of the aggregated distribution by the use of determing aggregation indices. Aggregation of the adults resulted from environmental variables. The models of theoretical sampling for the adults had been set up in the cotton fields. The parallel line method, the chess plate sampling method and ＂Z＂ method are the optimum sampling pattem in the fields.
