摘要
松梢象甲(Pissodes nitidus Roelots)是危害红松人工果林的主要害虫之一,它直接影响到果实的产量和质量。从红松林地的松梢象甲初查开始,经过样地调查、虫梢率与虫口密度测算,确定了虫害级别;并根据虫害级别确定了营林防治和化学防治措施,对有效控制松梢象甲的危害,起到了良好效果。
Pissodes nitidus Roelots is one of the most important pests in the artificial fruit forests for Pinus koraiensis, which can directly affect the yield and quality. We determined the infestation level by preliminary investigation, Sampling survey, measure and calculate the rate of shoots and population density, Ascertained the measures of silvicultural control and chemical control according to the pest level, It played a good effect on the control of Pissodes nitidus.
