摘　　要：核桃介壳虫在川北部分地区危害严重,主要危害核桃树主干、枝条,严重时也危害叶柄、叶脉。通过形态学和分子生物学鉴定,确定该虫为桑白盾蚧。桑白盾蚧在川北地区1年发生2代,4月上旬至5月中旬、9月中旬至10月中旬为若虫期,为该虫的最适防治时间。Walnut scale insects are seriously harmful in some areas of northern Sichuan,mainly harming the trunk and branches of walnut trees,as well as petioles and veins when the situation is serious.Through morphological and molecular identification,the insect was identified as the Pseudaulacaspis pentagona(Targioni-Tozzetti)and it occurred twice a year in this area.The juvenile nymphs period was from early April to mid-May and from mid-September to mid-October,which was the best time to control this insect in the area.
