摘　　要：为了探明视觉因素对云斑天牛(Batocera lineolata Chevrolat)成虫选择寄主颜色和寻偶行为的影响,采用室内色卡选择和视频轨迹捕捉系统(EthoVision 3.1)自动记录分析相结合的方法,对云斑天牛成虫的视觉选择进行了研究。色卡选择试验表明,在自然光下未交配雌虫对玄武石灰色(18.89%)、未交配雄虫对深黄色(14.44%)、已交配雌虫对绿松石绿(15.56%)的选择率最高;在人造光下未交配雌虫对褐齐墩果色(16.11%)、未交配雄虫对深黄色(14.44%)、已交配雌虫对绿松石绿(14.44%)的选择率最高。行为仪分析结果表明,当雌虫或雄虫被遮眼后,相应的搜寻时间、距离、头部转动角度和仰起次数都显著增加(P<0.05)。研究结果为云斑天牛行为控制技术的研究提供基础科学数据。In order to search the visual cues of the adults of Batocera lineolata Chevrolat to host color and mating behavior,we studied the color card selection of B .lineolata adults by laboratory observation in combination with automatic recording and analysis through video tracking capture system （EthoVision 3.1）.The test results by color card selection showed that the selection rates of unmated females to basalt grey （18.89%）,unmated males to saf-fron yellow （14.44%）,and mated females to turquoise green （15.56%）were the largest in the natural light;while the selection rates of unmated females to black olive （16.11%）,unmated males to saffron yellow （14.44%）,and mated females to turquoise green （14.44%）were the largest in the artificial light.The test results by behavior instrument showed that the search time,distance,angle of head rotation and number of head rearing of B .lineolata were increased significantly （P 〈0.05）,when the female or male was blindfold.The results of this study can provide a scientific basis for research of behavior control technology of B .lineolata .
