摘　　要：分析了降雨对湿地松粉蚧(Oracellaacuta(Lobdell))第1代初孵若虫试验种群的影响,结果表明,若虫的校正死亡率与降雨强度成线性相关,线性方程为Y=0,　　　　X<1 25Y=4 1+22 0X,X≥1 25,其中自变量X为降雨强度,Y为初孵若虫校正死亡率.The effects of precipitation on the 1st-instar nymph of the first generation of Oracella acuta were studied. The results indicated there was a linear relationship between its mortality and precipitation intensity, and the linear model was as follows: Y=0, X<1.25Y=4.1+22.0X,X≥1.25Note: X is precipitation intensity and Y is adjusted mortality.

关 键 词：湿地松粉蚧 第1代低龄若虫 降雨量 降雨强度 校正死亡率 线性相关
