枣尺蠖以幼虫取食枣树的嫩芽、花蕾和叶片,是为害枣树的主要害虫。在猖獗为害年份,常把枣树吃成光干,使红枣严重减产,甚至颗粒不收。为了有效地控制害虫,根据枣尺蠖的生活规律,经过多年的试验实践,初步总结出“挖、绑、堆、逮、撒、诱、涂、喷”的八字综合防治法。具体做法是:一、挖:就是挖越冬蛹。早春土壤解冻后至3月成虫羽化出土前,在树干基部周围挖越冬虫蛹。挖出之蛹可以集中处理,也可撒于地表供益鸟啄食。二、绑:就是绑阻虫带。成虫羽化出土之前,在树干基部距地面10～15厘米处绑10厘米宽的塑料带(装过化肥、农药的塑料袋
Jujube scales juvenile jujube feeding buds, buds and leaves, jujube damage is the main pest. In rampant years, often eat jujube dry, the jujube serious cuts, and even the particles do not accept. In order to effectively control the pests, according to the law of life of jujube tree, after many years of experiment and practice, the law of characters of “dig, tie, pile, catch, scatter, attract, paint and spray” is comprehensively summed up. Specific practices are: First, digging: that is, digging overwintering pupae. Early spring soil thawed to March before adult eclosion unearthed in the trunk around the base digging over the winter pupae. Dug pupa can be concentrated treatment, can also be sprinkled on the ground for the birds pecking. Second, tied: Is to tie the worm zone. Before the emergence of adult emergence, in the base of the trunk 10 to 15 cm above the ground tied 10 cm wide plastic band (loaded fertilizer, pesticide plastic bags
