据几年的观察,桃小食心虫在衡水地区枣树上一年发生两代。其成虫的发生与温、湿度关系密切,尤其是受湿度的影响更大。1982年,在1981年试验基础上,用桃小性诱剂进行田间诱测,根据蛾(雄)量的消长,结合温、湿度的变化进行预测预报及防治试验。试验区好果率平均达91％,比对照区提高27％。现将蛾量消长与温、湿度变化进行比较分析和探讨。
According to several years of observation, peach moth worms occur two generations a year in Hengshui area jujube. The occurrence of its adult and the temperature and humidity are closely related, especially affected by humidity greater. In 1982, on the basis of the experiment in 1981, the field test was conducted with the small louse lure and the prediction and control experiment was conducted according to the growth and decline of the moth (male) and the change of temperature and humidity. The good fruit rate in the experimental area averaged 91%, 27% higher than the control area. Now moth volume growth and temperature and humidity changes were compared and discussed.
