落叶松鞘蛾(Coleophora dchurica Flxovish)是落叶松主要潜叶害虫,近十年来在我省落叶松人工林内相继发生,猖獗为害,总面积达100万亩以上。由于该虫幼虫期生活隐蔽,大发生周期短,防治难度较大。1982年以来,作者在辽源市林业局与森防站协作下,在白泉镇炕家沟一带落叶松人工林内,对落叶松鞘蛾的分布和为害、生物学特性、发生与环境因素
Coleophora dchurica Flxovish is the main leaf-blade pests of larch. In the past ten years, it has occurred successively in the larch plantation of our province, causing rampant damage. The total area is over 1 million mu. As larvae of the larvae of life hidden, large short cycle, prevention and treatment more difficult. Since 1982, in collaboration with Forest Prevention Station of Liaoyuan City and Forest Prevention Station, the author studied the distribution and damage of the larch shell moth in the Larix gmelinii plantation in the area of Kangjiagou, Baiquan Town. The biological characteristics, occurrence and environmental factors
