不同波长杀虫灯对鳞翅目害虫的诱杀效果

用几种不同波长的杀虫灯对鳞翅目害虫进行诱杀,其中,1～6号灯中心波长在紫外光区,7～9号灯中心波长在可见光区。结果表明,紫外光区杀虫灯对夜蛾、毒蛾和灯蛾的诱集效果明显高于可见光区杀虫灯。一盏紫外光区杀虫灯诱集夜蛾、毒蛾和灯蛾虫数分别达可见光区杀虫灯的4.1,8.0,5.6倍。对于枯叶蛾和天蛾,不同波长杀虫灯诱集的虫数差异不明显。气象因素会影响日诱虫量,日诱虫量与温度、相对湿度、风速、云量和月光相关,温度和相对湿度与日诱虫量的相关系数分别达到0.37和0.22。

Effect Comparison of Different Wavelengths Insecticidal Lamps in Lepidopteran Pests Trapping

Several different wavelengths insecticidal lamps were selected to trap Lepidoptera pests.No.1～6 lights center wavelength was in the ultraviolet(UV) region and No.7～9 lights center wavelength was in the visible region.The results showed that the effect of UV insecticidal lamp for Noctuidae,Lymantriidae and Sphingidae was significantly higher than the visible insecticidal lamp.The number of insects killed by a UV insecticidal lamp,compared with a visible insecticidal lamp,reached 4.1,8.0 and 5.6 times,respectively.However for Lasiocampidae and Sphingidae,there was no significant difference in number of insects killed by different wavelengths insecticidal lamps.Weather factors had influence to the amount of attracting insects.Amount of attracting insects were corelated to temperature,relative humidity,wind speed,cloud cover and moonlight.The correlation coefficients of temperature and relative humidity to the amount of attracting insects were 0.37 and 0.22.
