| 中文摘要:为筛选高效光源以提高灯光对黑绒鳃金龟甲的诱杀效果，在室内采用昆虫行为学方法测试了黑绒鳃金龟甲成虫对14种单色光及不同白光光强的趋光行为。结果显示：14种单色光刺激下，黑绒鳃金龟甲成虫表现出不同的趋光行为，在紫光区400 nm和420 nm处趋光率最高，为39.72%；其次为绿光区498、524、562 nm处，趋光率分别为38.61%、38.05%和37.22%。该虫雌、雄成虫对14种单色光的趋光率存在差异，在460、483、524、605 nm处，雌虫的趋光率显著高于雄虫，分别达到38.89%、41.11%、41.67%和38.34%，雄虫则为28.33%、32.78%、34.45%和31.11%。不同白光光强刺激下该虫也表现出不同的趋光行为，最高趋光率出现在弱光强区域，雌、雄成虫分别达到51.67%和44.44%，随着光强增加趋光率下降，但最强光强时趋光率又有所增加。表明紫光和绿光为黑绒鳃金龟甲的敏感光源，且对弱光强更敏感；雌虫对光谱和光强的敏感性高于雄虫。 |

| Abstract:In order to screen the highly efficient light source for improving the light trapping effect for oriental brown chafer Serica orientalis Motschulsky (Coleoptera:Melolonthidae), the phototactic behavior of S. orientalis was measured to 14 monochromatic lights and different white light intensities by using insect behavior method in the laboratory. The results showed that S. orientalis adults showed different phototactic behaviors to 14 monochromatic lights, and S. orientalis had the highest phototactic rate of 39.72% in the violet region of 400 nm and 420 nm, and higher phototactic rates of 38.61%, 38.05% and 37.22%, in the green region of 498, 524 and 562 nm respectively. There was difference between the phototactic rates of females and males to the 14 monochromatic lights, and the phototactic rate of females was significantly higher than that of males at 460, 483, 524 and 605 nm; the female was 38.89%, 41.11%, 41.67% and 38.34%, while the male was 28.33%, 32.78%, 34.45% and 31.11%, respectively. S. orientalis also showed different phototactic behaviors to different white light intensities. The highest phototactic rate was present in the weak light intensity region, 51.67% and 44.44% for the female and male, respectively, then it decreased with increasing light intensity; however, the phototactic rate increased slightly at the strongest light intensity. In conclusion, S. orientalis was susceptive to the violet and green sections of the spectrum, and it was more sensitive to the weak light intensities. The sensibility of females to the spectral and light intensities was higher than that of the males. |
