摘　　要：采用聚集度指标方法，对板栗栗绛蚧（Kermes nawai Kuwana）在不同立地条件下的栗林进行空间分布型测定, 结果表明：该虫在虫口密度＞0.3 头/10cm 时, 空间分布为聚集分布，回归方程为：m*=3.107+1.512, 相关系数Υ= 0.7 957；应用 Ⅰwao 提出贯序抽样公式，在 Τm≥Τn 时，需要进行防治；对江山市高虫口栗林进行化学防治，35%快克乳油 1 000 倍喷雾防治效果达 93.17%。Determianation by crowding level of spatial distribution type of Kermes nawae in Castanea mollissima stands with different site conditions demonstrated that when the density reached 0.3/10cm, the spatial distribution was crowding one,with regression equation of m = 3.107+1.512,correlated coefficient γ=0.7957.According to sampling formula of Ⅰ wao, when Tm > Tn, it needs to be controlled.Chemical control of high population density in Castanea mollissima stands resulted over 93.17% efficiency in Jiangshan,,Zhejiang province.
