摘要
栗雪片象(Niphades castanea Chao)以幼虫蛀食板栗栗苞基座引发栗苞提前脱落,是重要的板栗果实害虫之一。为了解栗雪片象在罗田县板栗园的为害程度,于2016年8月至9月选取标准地进行了调查。结果表明,栗雪片象在白庙河镇跨马墩村、胜利镇大竹园村和畈里边村、河铺镇胡家湾等各调查点都引起了重度危害。在栗仁膨胀盛期有虫栗苞率为29.80%~53.60%,在板栗采收期为38.20%~62.66%。栗雪片象的发生与栗园的种植和管理方式存在一定的关系,但与板栗品种间关系不显著。
Niphades castanea Chao is one of the important fruit insect pests of Castanea mollissima Blume, causing the chestnut involucre abscission ahead of time by the larvae boring and feeding the basal involucres. In order to understand damage of N. castanes in Luotian county, investigation was conducted from August to September 2016. Damage of the pest were serious in Kuamadun village Biaomiaohe town （BK）, Dazhuyuan village （SD） and Fanlibian village Shengli town （SF）, Hujiawan Hepu town （HH）, with damage ratio ranged from 29.80% to 53.60% in chestnut kernels swelling period and ranged from 38.20% to 62.66% in chestnut harvest period. The damage degree was related to cultivating and management modes in a certain extent, while it had no significant relationship with chestnut varieties.
