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.
