松沫蝉与松枯梢病的关系及其防治

The Association of Pine Spittle Bug with Sphaeropsis Shoot Blight and Its Control

研究表明，松枯梢病（Sphaeropsis sapinea)是辽宁单古台樟子松（Pinus sylvestris var.mongolica)林木死亡的直接原因，松沫蝉（Aphrophora flavipes)对松枯梢病的发生与危害有明显的促进作用。在防治松枯梢病的过程中，不能忽略松沫蝉的防治。用50％甲胺磷原液或5倍液注干或涂干、500倍液喷雾等是防治松沫蝉幼龄若虫的适宜措施。采用“林敌”烟剂防治成虫是一种简便易行的有效办法。

The death of the rees of Pinus sylvestris var.mongolica in Zhanggutai, Liaoning Province, resulted directly from sphaeropsis shoot blight. The pine spittle bug, Aphrophora flavipes evidently investigated the fungal infection. The control of the spittle bug should not be neglected while controlling the fungal disease. Injection or brushing of tree trunk with the original product or its 5× dilution of 50% methamidophos, or crown spraying with 500× solution, etc. was suitable for controlling the early instar nymphs. Application of the lindane & trichlorfon smokes proved to be an easy and effective measure against the adults.
