摘　　要：对赣南地区湿地松粉蚧生物学特性和生活史进行观测，湿地松粉蚧在赣南地区1年发生4代，以1龄若虫聚集在老针叶的叶鞘内或叶鞘层之间越冬，次年3月开始活动，卵期9～19d，若虫期22～34d，越冬代若虫期136～176d，成虫分有翅型雄成虫、无翅型雄成虫和雌成虫3种，雄成虫生命极短，虫期不到1星期，雌成虫虫期24～37d。The biological characteristics and life history of slash Oracella aeuta in South Jiangxi （Ganzhou） were observed. Results showed that slash pine mealybug in Ganzhou had 4 generations a year, with a gathering of one-year nymphs in the old coniferous leaf sheaths or sheath layers for hibernation, and started its activities in March next year, with its egg stage 9-19 d, nymph stage 22-34 d, and over-wintering nymph stage 136-176 d. Its adults included sub-winged male adults, wingless-type male adults and female adults. The male adults＇ life was very short, for less than one week, but the female adults＇ for 24-37 d.
