一、前言海龙县有落叶松人工林479,500余亩,红松人工林13,500余亩,近年来遭受红松球蚜(Pineus sp)和落叶松球蚜(Adelges Laricisvall)危害,落叶松林发生面积近25万亩,红松林发生7,000亩,严重影响了受害树木的生长,为探索一条经济有效的治理方法,我们从1983年冬开始,利用人工饲养和捕捉的异色瓢虫Leis axyridis(Pallas)防治上述两种蚜虫的生产试验研究。二、试验材料与方法 (一)供试虫源:共有两批,一是于83年10月采集异色瓢虫的成虫共39,000头,放于地 I. Introduction Hailong County has 479,500 acres of larch plantation and 13,500 acres of Korean pine plantation. In recent years, it has been endangered by pine aphids and Adelges Laricisvall. Larix forest area has nearly 25% In the area of ​​10,000 mu, there are 7,000 mu of korean pine forest, which seriously affected the growth of the affected trees. To explore a cost-effective method of management, we started from the winter of 1983 and used the artificial feeding and catching Leis axyridis (Pallas) Production test of two aphids. Second, the test materials and methods (A) for the test source: a total of two batches, one in October 83 collected a total of 39,000 adult lady beetle, placed in the ground
