通过室内个体饲养观察,明确西方盲走螨捕食山楂叶螨和李始叶螨生长发育情况良好。1983~1985年,兰州田间试验表明:5月下旬到6月中旬,根据苹果树的不同树龄和叶螨的虫口基数,以1:36~64的益、害比,每株释放西方盲走螨雌成螨350~2,750头,经过45~60天,释放树上山楂叶螨和李始叶螨的种群数量发展缓慢,渐趋衰亡,达到完全控制。释放西方盲走螨不仅当年控制李始叶螨为害,可减少用药3~4次;其效果可持续两年。
Through individual indoor feeding observation, it is clear that the growth and development of the western blind walking mite predation hawthorn spider mite and the spider mite are good. From 1983 to 1985, field experiments in Lanzhou showed that: from late May to mid-June, according to the different ages of apple trees and the number of spider mites, 1: 36-64 Female adults 350 ~ 2,750 mites, 45 to 60 days after the release of the tree hawthorn spider mites and spider mite population development slow, gradually declining, to achieve full control. The release of western blind walking mites not only control Lee spider mite damage, can reduce the medication 3 to 4 times; the effect can last two years.
