棉盲椿是陕西棉花的主要害虫,自1952年迄今六年来已有三来成灾,严重地影响了棉花的产量。如以关中灌溉棉区为例,因其为害每年平均损失在25—34%之间,严重者可达60%或更多。为解决这一问题,我们从1954年开始进行了观察和防治试验,四年来已初步掌握了他在陕西的发生规律,摸出了一套防治方法,有效地控制了盲椿的为害。兹将有关资料整理如下,以供各地参考。
Cotton bollworm is the major pest of cotton in Shaanxi Province and has been hit three times in six years from 1952 to now, seriously affecting the yield of cotton. Take Guanzhong irrigated cotton area as an example, the average annual loss due to its damage is between 25-34%, with severe cases reaching 60% or more. In order to solve this problem, we started the experiment of observation and prevention in 1954, and initially mastered the law of his occurrence in Shaanxi Province in the past four years and worked out a set of prevention and control measures to effectively control the damage caused by D. chinensis. I will organize the following information for reference.
