摘　　要：采用在培养皿底部粘贴彩纸和制作彩色卵卡的方法观察大蛾卵跳小蜂Ooencyrtus kuvanae Howard雌蜂对黑、白、紫、绿、红、黄、蓝和棕黄8种颜色的趋性,以及不同颜色对其寄生率的影响。结果显示:大蛾卵跳小蜂雌蜂对黄色和棕黄色的首次选择率极显著高于透明对照,对紫、绿、红、黄、蓝5种颜色的首次选择率显著高于透明对照,对黑色和白色的首次选择率与透明对照无显著差异;在紫、绿、红、黄、蓝和棕黄6种颜色上的停留时间都极显著高于对照;对棕黄色的首次选择率显著高于红、紫、蓝3种颜色,在黄色和棕黄色的停留时间,显著高于红、紫、蓝、绿4种颜色。大蛾卵跳小蜂雌蜂对黄色和棕黄色卵卡上柞蚕Antheraea pernyi卵的寄生率极显著高于透明卵卡对照,对绿色的寄生率显著高于透明卵卡对照,对黑色的寄生率极显著低于透明卵卡对照。大蛾卵跳小蜂雌蜂在寄主选择时对黄色和棕黄色的趋性最强,其次是绿、红、蓝和紫,对黑色的趋避性最强。To determine the effect of color on the taxis of female adults Ooencyrtus kuvanae Howard,colored papers stuck on a petri dish and colored egg cards were adopted to test preferences and parasitism rate of O.kuvanae on eight colors,including black,white,purple,green,red,yellow,blue,and light brown.The results showed that first-choice rates for yellow and light brown of O.kuvanae were extremely significantly higher than transparent control,and first-choice rates for purple,green,red,yellow were significantly higher than transparent control.The first-choice rate showed no significant differences among black,white,and the control.The residence time of O.kuvanae were significantly longer on purple,green,red,yellow,blue,and light brown than transparent control.The first-choice rate for light brown was significantly higher than red,purple,and blue.The residence time on yellow and light brown was significantly higher than on red,purple,blue,and green.The female adult parasitism rates of tussah eggs,Antheraea pernyi,were extremely significantly higher on yellow and light brown cards,and significantly higher than transparent control for green but significantly lower than control for black.The female adults of O.kuvanae strongly preferred to yellow and light brown in host selection,followed by green,red,blue,and purple,and showed the most avoidance for black.
