利用害虫对不同颜色的趋性进行害虫防治,如利用黄板对实蝇的监测和防治已有很长的历史,然而尚未见把颜色量化进行实蝇对颜色偏嗜性研究的报道。为探明对瓜实蝇Bactrocera cucurbitae最具吸引力的颜色及其虚拟波长,本试验应用DanBruton的虚拟波长与RGB值的函数关系,把RGB值转换为虚拟波长;选择RGB值[(0,213,255),(0,255,146),(54,255,0),(129,255,0),(195,255,0),(255,255,0),(255,190,0)和(255,119,0)]的颜色进行打印,这些颜色对应的虚拟波长分别是480,500,520,540,560,580,560和600nm;在八面体内进行瓜实蝇对8种颜色的偏嗜性试验。结果表明:波长在520～560nm之间对应的颜色对瓜实蝇的吸引率高于其他虚拟波长对应的颜色,而540nm(黄绿色,RGB值为129,255,0)对应的颜色纸对瓜实蝇的吸引率最大。此外田间颜色偏嗜性试验也证实了黄绿色对瓜实蝇有最强的引诱作用。结果说明,黄绿色(虚拟波长540nm)是吸引瓜实蝇的关键颜色,黄绿色粘虫板可作为监测与防治瓜实蝇的一种有效方法。
Pest control of different colors of pest control, such as the use of yellow board on the detection and control of fruit flies has a long history, but yet to see the color quantification of fruit flies on the color deviation of the study reported. In order to find the most attractive color and its virtual wavelength for Bactrocera cucurbitae, this experiment uses the DanBruton’s virtual wavelength as a function of RGB to convert the RGB values to virtual wavelengths. Choosing RGB values [(0,213,255), (255,255,0), (255,255,0), (255,190,0) and (255,119,0)], the virtual corresponding to these colors The wavelengths were 480, 500, 520, 540, 560, 580, 560 and 600 nm, respectively. Eight octopus biofuels were tested in octahedron. The results showed that the corresponding color of the wavelength between 520 ~ 560nm was higher than that of other virtual wavelengths, while the color of 540nm (yellowish green, RGB value 129,255,0) The most attractive rate. In addition field color preference test also confirmed the yellow-green melon fruit fly has the strongest inducement. The results showed that yellow-green (virtual wavelength of 540nm) is the key color to attract fruit fly, yellow-green sticky board can be used as an effective monitoring and control fruit fly.
