| Abstract: | 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. |
