摘    要:中华松针蚧Sonsaucoccus sinensis (Chen)在九寨沟主要危害油松,也危害其他松类。该虫1 a发生1代,主要以2龄若虫在松针上越冬;3月下旬雄若虫老熟,出壳结茧化蛹,5月上旬成虫羽化交配,6月上旬开始产卵,6月下旬若虫孵化,发育至2龄于10月下旬开始越冬。年发生动态分越冬代为害、初孵若虫为害和虫口自然消减3个时期;发生为害程度与温度、湿度、海拔、坡向等环境因子密切相关。

关 键 词:九寨沟  中华松针蚧  生物学特性

Abstract:Sonsaucoccus sinensis(Chen)mainly attacks Pinus tabulaeformis and other Pinus spp.in Jiuzhaigou.It has one generation a year and overwinters in needles as the nymph in the 2nd instar.The male nymph matures and pupates in the last ten days of March.The adult emerges and mates in the first ten days of May and lays eggs in the first ten days of June.The nymph hatches in the last ten days of June and begins to overwinter in in the last ten days of October.It annual dynamic trend includes 3 stages,namely damage ...
