摘　　要：为提高农田灯光诱虫效率以及农田灯光诱虫装置的自动化开关灯条件的合理设计提供理论依据,实验分别于湖南南部、中部及北部3地的烟地或菜地设置若干台太阳能诱虫灯,每日收集各诱虫灯下的重要害虫和天敌,并进行鉴定、计数或烘干称重,然后比较同一地点或不同地点诱虫灯之间诱虫量的差异,并用相关-回归法分析每日诱虫量与每日重要气象因子之间的各种复杂关系。结果表明:诱虫量与大气日平均气温呈显著正相关关系(即灯光诱虫量随气温的升高而显著增加),而与气压、降雨和相对湿度则呈显著的负相关关系(即灯光诱虫量随气压或湿度的升高以及降雨的发生而显著减少),即高温、低湿、低气压和少雨天气有利于提高农田灯光诱虫的效率。To improve the efficiency of the light trap in farmland and supplies reasonable design with theory basis for the condition of farmland light traps ' automation switch,this experiment set the solar light trap at tobacco or vegetable fields in southern,central and northern of Hunan,collected the important pest and natural enemies in light traps daily,and identify,counting or drying weighing;then compare the difference of insect quantity between the same sites or the different sites,and got the relationship between the major weather factors and the insect quantity by applying methods of canonical correlation analysis and regression analysis.The results indicated that the light trap catches was positively significant related to the average daily temperature (the light trap catches increased by the average daily temperature),while the light trap catches was negatively significant related to the pressure,rainfall and relative humidity (the light trap catches decreased with the pressure,rainfall and relative humidity).The warmer and drier weather conditions can improve the efficiency of light trap.
