摘要
松实小卷蛾是我国松树上严重的蛀梢、蛀果害虫。该虫在浙江省一年4代,以蛹在枯梢和被害果内越冬。本文叙述了该虫成虫的羽化规律,各代幼虫钻蛀嫩梢和球果的不同习性及害虫发生与树龄、其它蛀梢,蛀果害虫和天敌的关系。通过试验,提出了灯光诱蛾、打孔注射杀虫剂、早春喷洒40％SN-851等杀虫剂和人工采摘害果和害梢的防治措施。
Petrova cristata Walsingham is an important insect pest which damaged cones and shoots of Pinus massoniana in China. This paper deals with the study on its bionomics and control measures which was conducted during 1987~1990 in Zhejiang Province. The insect has 4 generations a year in Chunan County, Zhejiang Province. Pupa overwinter in damaged shoots and cones. Daily eclosion frequency and cumulative adults of P. cristata were observed. This paper describes the ecological relationships between occurrence of the insect and age of stand, natural enemy and other insect pests of boring cones and shoots.The effective measures to control this pest are blacklight trap, spraying the insecticides of SN-851 in early spring and punch-injection of SN-851.
