摘要
根据作者 1983～ 1989年和 1994～ 1999年的 13年资料分析 ,3月 1日至 4月 10日的平均气温是影响第一代卵孵化盛末期的关键因子 ,r=- 0 .991(P<0 .0 1) ,影响越冬代成虫高峰始期的关键因子是 3月份的平均气温 ,r=- 0 .9762 (P<0 .0 1) ,预测期限分别达 30～ 40天和 15～ 30天 ,准确率分别达 98.16%和 93.65%。
WT6BZ]Based on the data from 1983 to 1989 and from 1994 to 1999,the mean temperature from March 1 to April 10 was the key factor affecting the hatching late stage of first generation (r=0.991,p<0.01) and the mean temperature of March was the major factor affecting the peak stage of adult of overwintering generation (r=0.976,p<0.01) of citrus spiny white fly ( Aleurocanthus spiniferus Quaintance). The forecast period was 30～40 days and 15～30 days,respectively. The forecast accuracy was 98.16% and 93.65,respectively. [WT6HZ]
