瓜实蝇对虚拟波长下不同颜色的趋性（英文）

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Dan Bruton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600 nm； 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520~560 nm 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540 nm (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540 nm）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。

Preferences of Bactrocera cucurbitae (Diptera: Tephritidae)to different colors: a quantitative investigation using virtual wavelength

 Various colors have been used as visual cues to trap insect pests. For example, yellow traps for monitoring and controlling of the fruit flies have been used for a very long time. However, the chromatic cue of using color traps has never been quantitatively investigated. To reveal which wavelengths are most attractive to the fly, experiments were conducted to evaluate the preferences of Bactrocera cucurbitae to different colors. In this study, RGB values and virtual wavelengths were converted each other based on Dan Bruton’s wavelength to RGB function. Eight color papers were printed by color printer based on RGB values ［(0, 213, 255), (0, 255, 146), (54, 255, 0), (129, 255, 0), (195, 255, 0), (255, 255, 0), (255, 190, 0) and (255, 119, 0)］ and were chosen to test the color preference of the melon fly, Bactrocera cucurbitae in an octagon maze, and their equivalent wavelengths were 480 nm, 500 nm, 520 nm, 540 nm, 560 nm, 580 nm, 560 nm, and 600 nm, respectively. The color papers with the spectrum between 520-560 nm showed higher attractiveness than the others, and that with the spectrum of 540 nm (chartreuse green, with RGB values of 129, 255, 0) showed the highest attractive rate. In addition, field preference experiment was done to confirm the effect of the chartreuse green color. The results suggest that chartreuse green stimuli (spectrum 540 nm) should be a crucial cue to attract B. cucurbitae, and chartreuse green sticky traps could be a useful device for monitoring and managing B. cucurbitae.
