吴堡县(现并入绥德县)位于陕北黄河沿岸,是一个盛产枣子的地区,年产量在136万斤以上。每年除向外地销售约半数以外,还充作部份口粮,是当地农民的一项重要收入。但近年来由于枣尺蠖的猖獗,产量大减,严重的往往数年无收,因此引起了领导上的重视,先后指定专人对牠的生活习性与防治方法作了研究。两年以来,在防治上取得了初步的成果,所以1958年全县枣树被害极轻,大大保证了丰收。我们为了彻底消灭这一害虫,特将其生活习性与防治方法分述于后,以供各地参考。
Wubao County (now incorporated into Suide County) is located in the Yellow River in northern Shaanxi, is rich in dates area, annual output of more than 1.36 million kilograms. In addition to selling about half of each year to the outside world, but also as part of rations, is an important income of local farmers. However, in recent years, because of the rampant jujube scale, the output is drastically reduced, and the serious ones tend to be confiscated for several years. Therefore, they have drawn great attention from the leaders and assigned specialists to study their living habits and prevention methods. In the past two years, initial results have been achieved in prevention and control. Therefore, the jujube tree in the county was extremely vulnerable in 1958, which greatly ensured the good harvest. In order to completely eliminate this pest, we will be divided into its habits and methods of prevention and treatment for reference.
