利用气候因子为主的李小食心虫生态防治

在李小食心虫Grapholitha fanebrana Treistchek发生规律及主要习性研究的基础上，提出以利用吉林省气候特点为主的综合防治措施。秋天利用5cm土层未冻结前的强寒潮天气，减少越冬虫源；初春进行树下防治，利用土壤小气候特点，恶化越冬茧化蛹的小气候环境，降低虫源基数；成虫出现高峰期，尤其是越冬代和第一代成虫高峰期时，根据风向安放诱捕器或施放赤眼蜂。

The ecological control of Grapholitha fanebrana Treistcheke with climatic factors

Based on the study of the occurrence regularity and habits of Grapholitha Fanebrana in Jilin Province,the integrate control measures emphasizing on the climatic characteristics of Jilin Province were introduced.The strong cold currents before soil layer was frozen 5 cm deep in Autumn were made use of to decrease the pest sources and also the small climatic characteristics of soil were used to worsen the small climatic environment when cocoon pupates and decrease the number of pest sources.According to the wind direction,we set traps or release red-eye bees in peak.
