为明确重要害虫绿盲蝽在杭白菊园发生动态和防治措施,遂于2012年选桐乡市主栽品种早小洋菊、晚小洋菊、异种大白菊园及3品种分别与桑树间作园,自6月初每半月调查1次。结果发现,7月底—8月初、9月上中旬、10月中旬—11月下旬出现3个虫口高峰,以最后1个历时最长、虫口密度最大;绿盲蝽若虫和成虫嗜好花蜜,可长时期潜入花朵中刺吸;纯菊园中,异种大白菊园虫口最少,晚小洋菊园虫口最多;间作园中,晚小洋菊-桑树间作园虫口最多,早小洋菊-桑树间作园虫口最少。药效试验表明,新型农药锐劲特效果较好。建议在10月上旬实施药剂防治。
In order to clarify the dynamics and control measures of the important insect Apolygus lucorum in the Chrysanthemum Park, then in 2012 selected varieties of early spring chrysanthemum, evening primrose, heterophylla Daisy Juyuan and 3 varieties of mulberry trees intercropping with the mulberry trees, from 6 Monthly survey once every half month.
