| 摘 要： | 为探明重大入侵害虫椰心叶甲的最佳趋向颜色及其所对应的量化参数,应用Dan Bruton的虚拟波长与RGB值的函数关系进行相互转换,通过自制八面体装置测定椰心叶甲对不同颜色的选择性差异,确定其最佳趋向颜色、波长和RGB值。结果表明,椰心叶甲雌、雄成虫对不同颜色的选择率均存在差异,其中波长为580 nm的黄色(RGB值为255,255,0)对椰心叶甲的吸引力最高,其次为波长575 nm的黄绿色(RGB值为240,255,0),这为采用有色粘板技术监测和诱捕椰心叶甲提供了新的思路。 |

| Abstract: | In order to investigate the hobby color and the most attractive wavelength of Brontispa longissima, an octahedral device was applied to study the tropism of different colors and to screen their hobby color. The RGB values of different colors, which had a serious virtual wavelength, were obtained by Dan Bruton function. The results indicated that the attractive ratio of B. longissima varied significantly among the different colors, and the yellow, which with the wavelength of 580 nm and the RGB values was 255, 255, 0, had the highest attractive rate of B. longissima. The hobby color screening is significant to applying colored sticky board to monitor and control B. longissima. |
