| 中文摘要: |
| 石斛篓象成虫有其独特的取食行为习性：喜食叶片柄端（0~1/3）、茎干顶端（2/3~1），成虫一般只从叶的背面取食。应加强石斛苗移栽前的处理以及移栽后的监测和管理；可在石斛篓象幼虫、成虫的盛发期，依据特有的危害症状分别对其进行人工防治；可在石斛篓象成虫产卵高峰期后（1月底）采收3年生及以上石斛植株，从而减少田间虫口基数。化学农药防治成虫时，要重点喷施在叶片背面和茎干顶端。 |
| 英文摘要: |
| Nassophasis sp. adults had its particular feeding behavior. The adults preferred the petiole of the leaf and the apex of the stem, and ate the leaf from its back most. According to the bionomics and the symptom of Nassophasis sp., and the field management of Dendrobium Sw, some corresponding artificial control methods and prevention measures were put forward. Treatment before transplanting,monitoring and management after transplanting of Dendrobium seedlings should be strengthed. Artificial control methods should be taken at the peak period according to the specific damage symptom. To reduce the population base of Nassophasis sp., three or over three years old Dendrobium plants were suggested to be havested after the peak of laying (the end of January). Chemical pesticides should be sparying much more on the back of leaf and the apex of stem than other parts of the Dendrobium plants. |
