摘　　要：板栗绛蚧是板栗枝干上主要的刺吸性害虫之一,广泛分布于安徽、江苏、浙江、湖南、湖北、贵州、四川、江西等省的板栗产区。此虫1 a发生1代,以2龄若虫越冬,越冬后的2龄若虫和雌成虫固定寄生在板栗枝干上刺吸寄主汁液危害。成虫期4月上旬至5月下旬,行两性生殖,存在孤雌生殖,雌成虫平均产卵量为3 975粒。新若虫在5月上旬孵化,5月末达盛期。用10%高渗吡虫啉可湿性粉剂1 000倍液,在越冬若虫膨大期进行喷杀效果好。黑缘红瓢虫、寄生蜂和芽枝状芽孢霉菌是显著控制虫口密度的重要天敌。Kermes nawae Kuwana is one of the major piercing-sucking pest for Castanea moUissima, which distributed widely in the Chinese chestnut （ Castanea mollissima） production areas such as Anhui, Jiangsu, Zhejiang, Hunan, Hubei, Guizhou, Sichuan and Jiangxi provinces. K, nawae Kuwana has 1 generation a year and overwinters in the second nymphal stage. After overwintering the nymph and female insect mostly infests on the branch or trunk of Castanea moUissima to inhale the juice, The imago period is from the early April to end of May. The reproduction belongs to amphigenesis, but it may happen female parthenogenesis. A female average egg number is 3 975. The nymph hatches in early May and the peak of hatching is in end of May. It is effective control method to spray the crown with 10% highly permeable imidacloprid WP 1000-fold during the overwintering nymph bulge period. Chilocorus rubiclus Hope, Blastothrismys sp and Cluabos porium are the important natural enemies.
