中文摘要：
为了确定卷蛾分索赤眼蜂Trichogrammatoidea bactrae Nagaraja雌蜂的颜色偏好性,在室内通过在培养皿底部黏贴彩纸的方法测定卷蛾分索赤眼蜂雌蜂对红、黄、黑、紫、绿、白、蓝7种颜色的行为趋性反应。结果表明,卷蛾分索赤眼蜂雌蜂在红、黄、紫、绿和蓝5种颜色上的滞留时间都极显著地高于对照（P〈0.01）,在黑和白2种颜色上的滞留时间与对照没有显著差异（P〉0.05）;对黄色的首次选择率极显著高于对照（P〈0.01）,对红、紫、绿和蓝色的首次选择率均显著高于对照（P〈0.05）,对黑色和白色的首次选择率与对照没有显著差异。当雌蜂分别在黄与红、紫、绿和蓝两两颜色之间选择时,雌蜂在黄色彩纸上的滞留时间显著长于其他4种颜色。当雌蜂对红、紫、绿、蓝和黄色5种颜色一起选择时,在首次选择率、滞留次数上5种颜色间都没有明显差异（P〉0.05）;但在红色和蓝色上的滞留时间显著长于紫色（P〈0.05）,在这3种颜色上的滞留时间与在黄色和绿色上的滞留时间均无显著差异（P〉0.05）。卷蛾分索赤眼蜂雌蜂在7种颜色卵卡上分别与透明纸（对照）上的米蛾卵的选择寄生时,在黄色卵卡上的寄生卵量极显著多于对照（P〈0.01）,黑色卵卡上的寄生卵量极显著少于对照（P〈0.01）,其他5种颜色的卵卡上的寄生卵量与对照没有显著差异（P〉0.05）。结果说明,卷蛾分索赤眼蜂雌蜂对黄色最为偏好,其次偏好红、紫、绿和蓝色,较不喜好白色和黑色。
英文摘要：
In order to screen the preferred color of Trichogrammatoidea bactrae Nagaraja,the behaviour responses of T.bactrae to seven colors,i.e.,red,yellow,black,purple,green,white and blue,were investigated with petri dishes pasted underside with color papers in the laboratory.The results revealed that the retention duration of female wasps was significantly longer on red,yellow,purple,green and blue papers than on transparent ones（control）（P〈0.01）,but not on black and white ones.The percentage of first choice by female wasps to yellow was extremely significantly higher than to transparent color（P〈0.01）,and that to red,purple,green or blue was significant higher than to transparent color（P〈0.05）,but that to black and white was not significantly different from the control.In selection tests of two colors,the retention duration of female wasps on the yellow paper was significantly longer than those on other four colors when compared on yellow paper with red,purple,green and blue paper,respectively.However,in selection tests of multiple colors with red,purple,green,blue and yellow,no obvious differences were detected in percentage of the first choice and retention time of the wasps to five colors;while the retention duration of wasps on red and blue papers was significantly longer than on purple one,but no significant differences were detected between on these three color papers and on both yellow and green papers.The number of parasitized eggs on yellow paper was extremely significant higher than on the transparent paper（P0.01）,while the number of parasitized eggs on black paper was extremely significant less than that on the transparent paper（P0.01）.The number of parasitized eggs on the other five color papers,i.e.,red,blue,purple,green and white,was not significantly different from that on the transparent paper.In conclusion,T.bactrae has the highest preference to yellow,less preference to red,purple,green and blue,but the least preference to white and black.
