在采用诱捕法对松墨天牛成虫的发生、孕卵及其与气温关系进行了研究。在 1999年 8月 30日前 ,发生量与前 10d气温呈正相关 ,相关系数达 0 .70 97。通过对雌成虫的测量、解剖发现孕卵量与个体大小存在相关关系 ,两者模型为Y =1.6 7X - 18.4 8,(rxy=0 .94 39)。孕卵量有 2个高峰期 ,分别是 6月 3日~ 7月 12日和 8月 1日~ 9月13日。
The trapping method was used to study the occurrence of adult Monochamus alternatus and its relationship with temperature and its temperature. Before August 30, 1999, there was a positive correlation between the occurrence and the temperature in the first 10 days with a correlation coefficient of 0.7097. According to the measurement of adult female, the amount of egg of ovulation was correlated with the size of the individual, the model of which was Y = 1.6 7X - 18.48 (rxy = 0.9439). There are two peaks in the amount of eggs, which are June 3 to July 12 and August 1 to September 13, respectively.
