Abstract

The response of red deer calves (Cervus elaphus) to the odors of Sitka spruce (Picea sitchensis) and lodgepole pine (Pinus conforta) needles and five monoterpene constituents of their essential oils was measured by simple two-choice feeding trials. All odors were significantly rejected (P < 0.05) except Sitka spruce and lodgepole pine by females and Sitka spruce and alpha-terpineol by males. Females had a stronger dislike of all odors except lodgepole pine than males. Rejection of monoterpene odors weakened slightly with time. A strong logarithmic relationship between the strength of the rejection response and vapor pressure of the compounds tested suggested that the odors were rejected on the basis of concentration rather than quality.

摘要

通过简单的二选一进食试验，测定了赤鹿幼鹿（Cervus elaphus）对斯提克云杉（Picea sitchensis）和花旗松（Pinus conforta）针叶及其精油中 5 种单萜成分气味的反应。除了雌鹿对斯提克云杉和花旗松、雄鹿对斯提克云杉和α-松油醇不排斥外，所有气味均被明显拒绝（P < 0.05）。除了花旗松外，雌鹿对所有气味的厌恶程度均强于雄鹿。随着时间的推移，对单萜气味的排斥作用略有减弱。拒绝反应的强度与所测试化合物蒸气压之间存在强烈的对数关系，这表明这些气味是基于浓度而不是质量被拒绝的。
