摘要
1996～ 1 997年在深圳对黄曲条跳甲种群动态调查的结果表明 :该虫在一年中有两个发生高峰 ,即春季高峰和秋季高峰。秋季发生高峰的虫口数量是春季的 2 4～ 2 5倍。旬降雨量 (X1)、旬平均气温 (X2 )与黄曲条跳甲种群数量 (Y)之间的关系用数学方程式表达 :Y =2 7 1 5 37- 0 0 0 41 2 8X1+0 0 0 472 7X2 。黄曲条跳甲在一季菜生长期内的发生动态与寄主植物生长发育期密切相关。
The population dynamics of the striped flea beetle Phyllotreta striolata (F.) on crucifer vegetable were investagated in Shenzhen City during 1996-1997. The analysis results showed that its populations emerged two peaks, autumn peak and spring peak,in a year. The population quantity of autumn peak was 2.4-2.5 times as much as that of spring peak. The population numbers (Y) of the striped flea beetle was closely related to rainfall (X 1) and the average temperature (X 2) of a period of ten days. It could be described by the following equation: Y=27 153 7-0 004 128 X 1+0 004 727 X 2
