摘　　要：对2005—2010年低温雨雪冰冻灾害发生区松墨天牛Monochamus alternatus、马尾松毛虫Den-drolimus punctatus、湿地松粉蚧Oracella acuta、板栗疫病Cryphonectria parasitica的发生数据统计分析表明:2008年,松墨天牛发生面积呈暴发式增长,为偏重发生;马尾松毛虫发生面积急剧下降,重度发生面积下降77.6%,发生程度呈轻度、中度;湿地松粉蚧当年发生面积略有上升,但总体呈连续6年的下降趋势;板栗疫病发生面积呈逐年下降趋势,但发生程度为中等偏重,特别是2009年较2008年重度发生面积增加了57.7%。The results of the statistical analysis on the occurrence data of 4 forest pests in low temperature and frost disaster area between 2005 and 2010 showed： in 2008, the occurrence area of Monochamus alternatus increased tremendously and the occurrence was severe;the occurrence area of Dendrolimus punctams decreased sharply, the area of heavy damage decreased by 77.6% and the occurrence was light or moderate;the occurrence area of Oracella acuta increased slightly, but on the whole, it declined for 6 consecutive years;the occurrence area of Cryphonectria parasitica decreased year by year, but the occurrence degree was severe, the area of heavy damage in 2009 was 57.7 % more than that in 2008.
