落叶松芽瘿蚊(Dasineura Laricis F.LW.属于双翅目瘿蚊科(Cecidomyiidae)。它为害落叶松的花芽、叶芽。幼虫侵入芽内,分泌物质刺激幼芽徒长形成虫瘿。这种害虫早在50年代中期就有记载,只是当时为害不严重没有引起重视。直到60年代末期,随着落叶松种子园的广泛建立,才发现这种害虫在采种区内为害十分严重。落叶松因花芽被害结实很少,种子产量大幅度下降,从而引起人们注意,进行了一系列的研究。落叶松芽瘿蚊成虫纤细微小,体长2毫
Dasineura Laricis F.LW. belongs to the genus Cecidomyiidae which is the flower bud and leaf bud of the larch, in which the larvae invade the bud and the secretion material stimulates the budding bud to form the gall to grow. As early as the mid-50s there are records, but not serious damage was not paid attention until the late 60s, with the establishment of the Larix seed garden, only to find this pest in the mining area is very serious damage.Large flower buds Very few victims stubbornly, the seed yield dropped significantly, which drew people’s attention, conducted a series of studies.
