摘 要:1993年.在大庆市红旗林场。定期、系统地调查了柳蛎蚧1龄固定若虫、蛹、雌性成虫的死亡率以及初孵若虫、2龄若虫、前蛹、预蛹、蛹的发育进度预测模型。经检验.1龄固定若虫、蛹、雌性成虫种群数量变动的预测模型精度分别为 97. 80%、 87. 84%和 97. 12%。初孵若虫、2龄若虫、蛹的发育进度预测模型精度分别为95.75%,91.90%和95.27%A periodic systematic survey of the death rate of the first instar fixed nymphs. pupae and adult females as well as the development progress of the newly hatched nymphs. second instar nymphs. prepupae and pupae was performed in Hongqi Forest Farm of Daqing City. Heilonajiang Province. A dynamic model of population number of the first instar fixed nymphs. second instar nymphs, prepupae and pupae was formulated. Tests of these models demonstrated that the reliability of the dynamic model of first instar fixed nymphs. pupae and adult females were 97. 80%. 87. 84% and 97. 12% respectively, and the reliability of the development progress predicted model of newly hatched nymphs. second instar nymphs and pupae were 95. 75%, 91. 90% and 95. 27% respectively.
