中文摘要:

颜色是影响昆虫行为活动的一种重要视觉信号。本研究采用方差分析和t检验测定了玉米螟赤眼蜂雌性、雄性及雌雄个体间对白、黄、橙、粉、红、蓝、绿7种颜色卡纸的选择趋性差异，结果显示，不同颜色卡纸对玉米螟赤眼蜂雌雄个体的选择趋性均存在显著性影响（F♀=76.43，P♀＜0.05；F♂=25.23，P♂＜0.05）。且以白色卡纸为对照时，玉米螟赤眼蜂雌雄个体均表现为在黄色卡纸上的选择蜂量最高，分别为对照的1.77倍和3.20倍；在同一颜色卡纸上，玉米螟赤眼蜂雌雄个体间的选择差异也不尽相同。采用相关性分析探讨玉米螟赤眼蜂选择趋性同卡纸色彩参数的相互关系，结果显示，玉米螟赤眼蜂雌雄个体选择趋性与卡纸色泽亮度及黄蓝色程度（b）均呈显著的正相关（P＜0.05）。研究表明，玉米螟赤眼蜂雌雄个体均偏好黄色，且不同性别个体对同一颜色的偏好程度也不尽相同。此外，物体颜色的亮度和色调均能不同程度影响玉米螟赤眼蜂的偏好性。

英文摘要:

Color is an important visual signal affecting insect behavior actions. By using ANOVA and T-test, preference of Trichogramma ostriniae females, males and between sexes for seven kinds of color papers (white, yellow, orange, pink, red, blue, green) were investigated. The results showed that there were significant differences on the preference of T. ostriniae females and males for different color papers (F♀ =76.43, P♀＜0.05; F♂ =25.23, P♂＜0.05), respectively. The number of female and male parasitoids caught on the yellow paper was the largest, which was separately 1.77 and 3.20 times more than that caught on the white paper. Parasitoids preference for the same color paper between sexes was not completely equivalent. Correlation analysis was used to determine the relationships between parasitoids preference and color parameters (L value and b value). The results showed that there was significantly positive correlation between them (P＜0.05). The research indicated that both male and female T. ostriniaepreferred yellow color, and preference for the same color between sexes varied. Besides, parasitoids preference could be influenced by the brightness and tone of color.
