摘　　要：【目的】柑橘木虱(Diaphorina citri Kuwayama)是柑橘的主要害虫,是传播柑橘黄龙病的重要虫媒,研究柑橘木虱对颜色的趋性,对该虫的有效防治具有重要意义。【方法】采用自制长方体与八面体装置进行柑橘木虱的颜色趋性研究,选用的颜色根据RGB色彩模式进行设置,分别是红色(255,0,0)、橙色(255,128,0)、黄色(255,255,0)、黄绿色(128,255,0)、绿黄色(0,255,0)、蓝绿色(0,255,255)、蓝色(0,0,255),相对应的虚拟波长分别为690 nm、617 nm、580 nm、540 nm、510 nm、490 nm、440 nm。【结果】柑橘木虱雌、雄成虫对7种颜色的趋性存在显著差异,其中,黄色(255,255,0)对柑橘木虱吸引力最强,其次为黄绿色(128,255,0),红色(255,0,0)引诱效果最差。根据Dan Bruton虚拟波长与RGB值的转换关系,得出柑橘木虱主要趋向于510～617 nm的虚拟波长。【结论】黄色(580 nm)和黄绿色(540nm)能显著吸引柑橘木虱,红色(690 nm)对柑橘木虱吸引力最弱。【Objective】Citrus is an important economic crop in China, and Diaphorina citri Kuwayama (Hemiptera: Psyllidae) is a serious pest of citrus. It is also an important medium for spreading Huanglongbing the most devastating diseases on citrus production. In general, the areas where the Huanglongbing occur are also the distribution areas of D. citri. Currently, the control of D. citri relies largely on chemical insecticides. Intensive chemical control can induce many side effects, such as toxicity to non-target organisms including human beings, development of insecticide resistance, and insecticide residues on agricultural products and in the environment. To minimize such effects, alternative control strategies are required. One of the alternatives is to use color sticky traps. This method can be used in population monitoring, which can reduce the population density of pest. The purpose of the present study is to investigate the preference of D. citri to different colors.【Methods】In this study, the evaluated colors on the basis of the RGB color mode were set as red (255, 0, 0), orange (255, 128, 0), yellow (255, 255, 0), chartreuse (128, 255, 0), lime (0, 255, 0), cyan (0, 255, 255) and blue (0, 0, 255). The selfmade cuboid and octahedral devices were used to study the preference of D. citri to different colors. The indoor monochrome selection test of D. citri was tested with the cuboid device. The test was conducted in an indoor dark room at a temperature of (27.0 ± 2.0) ℃ and a relative humidity of 60.0%- 70.0%. Illumination was provided by hanging a white fluorescent light (20 W), 0.5 m above the cuboid device. The papers of the tested colors and the white (control) were stuck on the ends, respectively. For each bioassay, D. citri was individually introduced into the cuboid device from the middle part. The insect that felled on one of the tested paper was recorded after it remained for staying at least 60 s. Aftfive insects had been tested, the cuboid device was rotated 180° to randomize any positional
