摘　　要：松大蚜近10余年来在三门峡地区发生量越来越大,危害程度愈来愈严重。为此,对松大蚜在三门峡市的发生危害规律、生物学特性及防治技术进行了研究。研究发现,受害松树针叶枯黄、脱落,枝条干枯,严重时诱发煤污病;松大蚜以卵、若蚜越冬,每年发生10~12代,每年在5月中旬至6月中旬、10月份形成2次发生高峰;3月下旬、4月上旬倒春寒导致松大蚜自然死亡率大幅度提高;采取栽培技术防治、生物技术防治、化学技术防治可有效控制松大蚜的发生危害。In the past 10 years,the occurrence of Cinara pinitabulaeformis in Sanmenxia area has become more and more serious.Therefore,the occurrence regularity,biological characteristics and control techniques of C.pinitabulaeformis in Sanmenxia city were studied.The study found that the damaged pine needles were withered and yellow,and the branches were dry,which could induce coal blotch.The aphids overwinter as eggs and nymphs,and have 10-12 generations per year,with two peaks from mid-May to mid-June and October.The late spring coldness in late March and early April led to a significant increase in the natural mortality of C.pinitabulaeformis.The occurrence and damage of C.pinitabulaeformis could be effectively controlled by cultivation technology,biotechnology and chemical technology.
