摘要
研究了杉木球果主要害虫发生期与杉木球果生长期（下同）的关系：杉木球果麦蛾在杉木球果的各个生长期都起危害作用，但在杉木球果直径达２．５ｃｍ左右时危害最严重；长角岗缘蝽在杉木球果直径达到２．５ｃｍ左右至种子达到生理成熟期间危害严重；杉木扁长蝽在杉木球果的各个生长期都起危害作用，在成熟的球果中能剥到大量的杉木扁长蝽若虫。
This paper principally studied the relation between the main injurious insect emergence period and the growing period of Cunninghamia lanceolata cones and the results indicated that Dichomeris bimaculatus jeopardized C.lanceolata cones in their every growing period,but when the cone diameter reached about 2 5cm it jeopardized them most seriously; Gonocerus longicornis jeopardized the cones seriously from the cone diameter reaching about 2 5cm to the seeds reaching the physiological mature period;and Sinorsillus piliferus jeopardized the cones in their every growing period.
