摘　　要：樟子松(Pinus sylvestris var.mongolica)是我国三北地区主要的针叶造林树种。2012年在樟子松最早引种的章古台地区,松沫蝉(Aphrophora flauipes Uhler)大发生,松沫蝉长期吸食树液,消耗了大量的水分和养分,造成树木生长势衰弱,部分树木枯黄死亡。通过对松沫蝉泡沫表面蒸发量及滴落水滴耗水量连续观测,估算了松沫蝉额外消耗水分的量,结果表明,单株樟子松按虫口密度1181头(2015年飞防调查数据)计算,其在生长季内因松沫蝉危害损失约74.82 kg的水分。Pinus sylvestris var.mongolica is the main coniferous tree species planted in Northern China.In 2012,there is a large occurrence of Aphrophora flauipes in Zhanggutai,where Pinus sylvestris var.mongolica was first introduced.The long-term sap consumption by the phrophora flauipes consumed a lot of water and nutrients,resulting in the decline of growth and the death of some trees.After continuous observation and measurement,the amount of water consumed by the Aphrophora flauipes was estimated by two parts:the evaporation of the foam surface and the water consumption of the drip.According to the population density of 1181 in a single Pinus sylvestris var.mongolica(the investigation data of flight control in 2015),74.82 kg sap was consumed by the damage of Aphrophora flauipes in the growing season.
