| 中文摘要: |
| 枣镰翅小卷蛾是目前陕北红枣产区的一种重要害虫，其越冬老熟幼虫在每年9月中下旬有向下爬行在主干翘皮出化蛹越冬的习性。利用该虫这一生物学特性，研究使用无公害粘虫胶涂抹在枣树主干上，形成一粘虫胶环来粘捕枣镰翅小卷蛾幼虫。试验结果表明，使用粘虫胶涂抹宽度为20cm时效果最好，越冬蛹数量及来年的虫口数和枣树受害率大大降低，防治效果能达到85%以上。利用无公害粘虫胶粘捕幼虫的方法可明显减少化学农药使用次数，减轻环境污染，提高防治效果，降低防治成本，值得在实际生产中大力推广。 |
| 英文摘要: |
| Ancylis sativa Liu is an important pest in the jujube producing area in northern Shaanxi, and its overwintering larvae have the habit of crawling down on the main trunk of jujube trees and pupating in mid-to-late September each year. According to the biological characteristics of this insect, the pollution-free sticky glue was applied to the trunk for forming a coating to catch the larvae. The results showed that the control effect could reach more than 85% when the mean width of the sticky glue was 20 cm, and the number of overwintering pupae and the damage rate of jujube tree were greatly reduced. This method can significantly reduce the use of chemical pesticides, reduce environmental pollution, improve control effects, and reduce control costs. As a result, it should be highly promoted in actual production. |
