摘 要:通过对浙江省松阳县茶园越冬代黑刺粉虱发生期与相关气象因子进行回归分析,表明越冬代黑刺粉虱的发生高峰日与1—3月的日平均气温呈负相关,气温越高、高峰日出现时间越早,回归方程为y=51.15-2.93x(R^2=0.971)。进一步对越冬代黑刺粉虱的虫口密度动态进行模拟分析,表明Logistic模型Y=1/e^((0.503t+9.738))(R^2=0.968)和幂模型Y=e^((3.061 lnt+0.027))(R^2=0.968)对其种群动态增长的拟合度最高。研究结果对茶园中越冬代黑刺粉虱发生期与发生量的预测具有指导意义。Regression analysis was conducted on meteorological factors and occurring period of overwintering Aleurocanthus spiniferus adults in tea field of Songyang county, Zhejiang province. The results showed that occurring peak period of overwintering A. spiniferus adults was only negatively related with the daily average temperature of January to March. And the higher of the temperature, the earlier of the occurring peak period appeared. And the regression equation was y=51.15-2.93 x(R^2=0.971). According to analysis of density dynamics of overwintering A. spiniferus adults,the Logistic model and Power model showed the highest fitting effect for population dynamic growth, and the regression equation were Y=1/e^(0.503 t+9.738)(R^2=0.968) and Y=e^(3.061 lnt+0.027)(R^2=0.968), respectively. The results could be of significant references to predict the occurring period and quantity of overwintering A. spiniferus adults in tea field.
