为探索气象因子对蛀干类害虫引诱荆林问诱捕马尾松蛀干类昆虫效果的影响,于2006-2008年蛀干类昆虫活动期,在浙江省仙居县官路镇大北地溪林场应用蛀干类害虫引诱剂诱捕马尾松蛀干类昆虫,对诱捕到的昆虫总数及几种主要昆虫数量与15个气象因子分别进行通径分析和典型相关分析.结果表明:影响昆虫总数诱捕效果的气象因子为观察日前12 d内的雨日、20:00的平均低云量、平均水汽压、平均气温、平均总云量、平均最低气温;影响松墨天牛诱捕效果的气象因子为观察日前12 d内的平均最高气温、平均气压、平均最低气温、平均水汽压.可见,气温与平均水汽压对蛀干类害虫引诱剂林间诱捕蛀干类昆虫的效果影响较大.

An experiment was conducted to study the effects of meteorological factors on trap efficiency by trapping pine stem borers with pine stem borer attractant in Pinus massoniana forests in Xianju Dabei Oixi Forestry Center during 2006 and 2008. Hie path analysis and typical correlation analysis on the relationship between 15 meteorological factors and the amount of total trapped insects and the amount of main species of trapped insects were conducted separately. Results show that the meteorol ogicalfactors affecting the amount of total trapped insects are rainy days, average low-cloud amount at 20:00, average vapor pressure, and average air temperature, average cloud amount, and average minimum air temperature during 12 days before observation;those affecting trapping of Monochamus alternatus are average maximum temperature, average air pressure, average minimum temperature, and average vapor pressure during 12 days before observation. Therefore, air temperature and average vapor pressure are major factors affecting the attractant efficiency for pine stem borers in forests.
