摘要
桑拟轮蚧的发生危害受椒树的树龄、品种、种植模式、经营管理以及海拔和气候条件等因子影响,可通过改良品种、种植抗虫品种、加强经营管理和椒农混作等措施预防和减轻危害。危害发生后可通过刷壳涂干、更新复壮、药剂防治进行综合治理,药剂防治以吡虫啉.杀扑磷效果较好,1龄若虫发生盛期用药,防治效果达98.39%;2龄若虫介壳形成后用药,防治效果可达84.49%。
Occurrence and damage of Pseudaulacaspis pentagona in Zanthoxylum armatum were related with factors such as age of trees, varieties, planting patterns, management as well as altitude and cli- mate. Measures such as improving varieties, planting resistant cultivars, strengthening management and mixed plantation of the pricklyash and crops could prevent and reduce the damage. Stem coating, rege- neration and chemical control could be applied when the damage occurred. The control effect of imida- cloprid · methidathion was 98.39% in the peak of the 1st instar larva and 84. 49% after the formation of the scale in the period of the 2nd instar larva.
