摘要:为验证视觉信息在松墨天牛Monochamus alternatus Hope成虫寄主选择中的作用,并探索其对寄主健康状况的偏好,本文通过林间对寄主云南松针叶的色彩比对,选取国际标准色卡对应卡色作为视觉信号源,对松墨天牛雌、雄成虫的视觉选择进行了研究。研究表明,松墨天牛雌虫选择最多的颜色分别是:棕红色(选择率26.67%),赭石棕(选择率20.00%),栗棕色(选择率16.67%);松墨天牛雄虫选择最多的颜色为:信号褐(选择率26.67%),棕红色(选择率23.33%),栗棕色(选择率20.00%)。雌、雄成虫均偏好选择棕褐色系,对应于林间衰弱和濒死寄主针叶呈现的颜色,说明松墨天牛成虫通过视觉判断偏好攻击长势衰弱的林木,属于次期性蛀干害虫。
The article aims at proving visual effect in host selection of adult Monochamus alternatus,and exploring their preference to host health status.Based on color comparison with the coniferous colors of Pinus yunnanensis in woodlands,corresponding colors are chosen from the international standard color cards(RAL) and are used as visual signal source to investigate visual selection of male and female M.alternatus.The paper reveals that female M.alternatus choose red brown(selectivity:26.67%),ochre brown(selectivity:20.00%) and chestnut brown(selectivity:16.67%) most;while males select signal brown(selectivity:26.67%),red brown(selectivity:23.33%) and chestnut brown(selectivity:20.00%) most.Both females and males prefer brown series which are coniferous colors of weak and dying host trees,that is to say,adult M.alternatus,which prefers attacking weak trees based on vision decision,belongs to secondary xylophagous insect.
