马尾松毛虫(Dendrolimus punctatus Walker)是我国南方林区重要害虫,每6-9年周期性大发生一次。我区地处低岗丘陵,系马尾松毛虫常灾区,尽管多次采用飞机或人工大规模化学防治,但效果不显著,且大量杀伤天敌,大发生周期愈来愈短。自1989年起我们以徐桥地区为试验区,实行以营林为基础综合防治措施,连续十年较好地控制了马尾松毛虫灾害,特别是1996年安徽省马尾松毛虫大发生,周边低岗丘陵地区马尾松严重成灾,而试验区仅边缘地区小块状发生成灾,大面积松林安全。
Dendrolimus punctatus Walker is an important pest in the forest area of southern China and occurs periodically once every 6-9 years. My area is located in the low hillock, Department of Masson pine caterpillar affected area, despite repeated use of aircraft or artificial large-scale chemical control, but the effect is not significant, and a large number of natural enemies, the shorter the cycle of large occurrence. Since 1989, we took Xuqiao area as experimental area, implemented comprehensive prevention and control measures based on silviculture, and controlled the caterpillar disaster of Dendrolimus punctatus for ten years in a row. Especially in 1996, masson pine caterpillars occurred in Anhui Province and low around Masson hill area Masson disaster seriously affected, but only the edge of the experimental area small block disaster occurred, a large area of pine forest security.
