摘要
本试验筛选出鱼藤氰、敌敌畏、敌百虫、久敌和高好灭百可等５种农药，均对香蕉冠网蝽有较好的防治效果．在成虫高峰期施药，虫口减退率是喷药２次的比只喷１次的明显．如果从防病角度来考虑，最好是在３龄若虫高峰期喷药，因为从４龄开始已能够传播病害，而且防治效果比喷杀成虫高．
Five insecticides including 1.3%fenvaleratr+rotenone EC.,40% DDV P EC.,90%trichlorphon ,40%monocrotophos +trichlorphon EC,,5%alphacypermethrin EC,,for control of banana lacebug(Stephanitis ty Picus Distant)were highly effective. Spraying twice was more effective than once while applying at the peak of adult stage. It was the best treat- ments to spray the nymph of 3rd instar for reducing population of banana lacebug and spread of disease.
