沙河市老爷山林场油松近几年连续发生大面积松扁叶蜂危害。2001年用机动喷雾器防治,由于山区林场地形复杂,水源缺乏,喷药液防治困难,致使2001年越冬基数加大,2002年发生更为严重。为此,今年改用喷烟机进行喷烟防治,取得了很好的防治效果。一、防治区概况防治区为老爷山林场严重发生区域,该区越冬虫口密度平均达到760头/株,树龄为28年,油松人工纯林,平均树高7米,郁闭度0.7。二、防治药剂和药械药剂为南京红太阳集团生产的4.5%的高效氯氰菊酯,烟剂载体为柴油,药剂和柴油混合比例为1:5,即将4.5%的高效氯氰菊酯按比例放入柴油中,使之均匀溶解,即成烟剂。器械为江苏南通广益机电有限公司
In recent years, a large area of Pinus tabulaeformis was found in Pinus tabulaeformis in Dailianshan Forest Farm in Shahe City. In 2001, it was prevented and controlled by the mobile sprayer. Due to the complex topography of the forest in the mountainous area and the lack of water, the prevention and control of spraying liquid was difficult. As a result, the base of overwintering in 2001 increased and became even more serious in 2002. To this end, this year to switch to smoking machine spray prevention and control, and achieved good control effect. I.

The density of overwintering insect population reaches 760 heads per plant at an average age of 28 years. The Pinus tabulaeformis artificial pure forest has an average height of 7 meters and a closedness of 0.7. Second, the prevention and treatment of pharmaceuticals and Pharmacy Pharmacy Nanjing Red Sun Group produced 4.5% beta-cypermethrin, tobacco carrier for the diesel fuel, pharmaceutical and diesel mixture ratio of 1: 5, about 4.5% of the beta-cypermethrin into the proportion of diesel The uniform solution, that into the smoke agent.
