摘要
对黑龙江省牡丹江地区危害樟子松Pinus sylvestnis var. mongolica的松沫蝉Aphrophora flavipes Uhle的分布及发生规律进行了调查。结果表明:樟子松纯林最适合松沫蝉种群的生长和繁殖,近林缘处虫口密度最大,约152. 33头/株,在樟子松枝条上呈明显的垂直分布,多集中于上部枝条;松沫蝉的发生受坡向、郁闭度、地被植物和树龄等林地条件及气候条件影响较大,阳坡比阴坡受害严重,地被植物越少受害越严重,郁闭度和树龄越小受害越严重,4—7月平均降雨量和平均相对湿度是影响松沫蝉发生的主要气候因子,降雨量和相对湿度越大危害越严重。
The distribution and occurrence of Aphrophora flavipes Uhler damaging Pinus sylvestnis var.mongolica Litv.was investigated in Mudanjiang of Heilongjiang Province.The results showed that the pure forest was most suitable for the growth and reproduction of the poplation of A.flavipes,and the largest population density was found near the forest edge,which was about 152.33 heads per plant.The population of A.flavipes showed obviously vertical distribution on P.sylvestnis var.mongolica Litv.,and most individuals were focused on the top branch.The woodland conditions,containing slope direction,canopy density,ground cover plants,tree age and climatic condition,had a great effect on the occurrence of A.flavipes.The sunny slope sufferred more seriously than shady slope;the forest with lesser ground cover plants sufferred more;the forest with less canopy density and younger tree age sufferred more;average rainfall and average relative humidity from April to July had larger effect on the occurrence of A.flavipes,and the forest with heavier rainfall and higher relative humidity from April to July sufferred more.
