摘　　要：华山松球果螟是危害华山松种实的主要害虫.利用华山松不同方位虫口密度与样地虫口密度回归分析确定华山松球果螟越冬幼虫的最适抽样方位为西面,应用Iwao,Talor,m*-v及La-m回归模型确定序贯抽样方程和最适抽样数,并以La-m模型为例制作华山松球果螟越冬幼虫序贯抽样表.Dioryctria rubble is the major pest that damages the cones and seeds of Pinus amandii. It was determined by regressive analyses between the larva densities in different orientations and the larva densities of the sample plots that the optimal sampling orientation was the west for over - wintering larva of Dioryctria rubble. The sequential sampling equations and optimal sampling numbers were set by Iwao, Talor,m^＊ -v and Lα -m regressive models. And the sequential sampling table for over - wintering larva of Dioryctria rubble was made as an example by means of Lα -m regression model.
