| 摘要: |
| 为掌握广西沙塘林场马尾松毛虫越冬幼虫虫情,对虫情发生情况进行科学预报和评价,于2006~2010年每年的12~1月在该林场设置固定标准地进行虫情调查监测,并采用灰色关联度分析法进行虫情综合评价。结果表明,2006年林场马尾松毛虫越冬幼虫大发生,其它年份没有大发生,仅虫源地有大发生趋势,5年间马尾松毛虫越冬幼虫虫情综合评价系数由大到小,虫情由重到轻排序为2006年 > 2008年 > 2009年 > 2010年 > 2007年。生产部门有必要加强马尾松毛虫越冬幼虫的监测管理。 |

| Abstract: |
| Scientific prediction and evaluation for the occurrence of insect pest situation of Dendrlimus punctatus walker.over wintering larva were conducted in Guangxi Shatang Forest-farm, in order to grasp the situation.The investigation and monitoring were carried out by setting fixed sample plots in the forest-farm from December to January every year in 2006~2010.Gray correlation analysis method was used for comprehensive evaluation of insect pest situation.The results showed that D.punctatus walker.over wintering larva in the forest-farm was outbreak in 2006, whereas there were no outbreak in other years.Outbreak trend was only in the site of insect-source.During 2006~2010, the coefficients of comprehensive evaluation were orderly from big to small for D.punctatus walker.over wintering larva and from severe to slight for insect pest situation, which were 2006 > 2008 > 2009 > 2010 > 2007.It is necessary to enhance the monitoring and managing of D.punctatus over wintering larva in production dapartment. |
