在拴绳行走条件下，研究了盲法成年雄性蟑螂对吸引性和厌恶性气味的行为反应。一种性信息素样兴奋剂来自成年处女女性和人工合成的柠檬烯分别作为吸引和厌恶的气味源。当一个搜索动物刺激有吸引力的女性衍生的气味，水平偏转的触角增加，在大多数情况下，垂直触角的位置向下移动。刺激也显著降低了动物的行走速度。这些行为变化意味着对周围环境的仔细搜索。性信息素的后效是更明显的运动比触角运动。另一方面，刺激厌恶性气味（柠檬烯）往往会抑制主动触角运动，也增加了步行速度。在厌恶性气味消失后，触角的主动运动立即恢复，行走速度迅速降低到与控制期大致相同的水平。这些结果表明，反应的性质相反类型的气味是互惠对方的触角运动和运动。
The behavioral responses to attractive and aversive odors were examined in blinded adult male cockroaches under tethered-walking conditions. A sex pheromone-like stimulant derived from adult virgin females and artificially synthesized limonene were used as attractive and aversive odor sources, respectively. When a searching animal was stimulated with the attractive female-derived odor, the horizontal deflections of both the antennae were increased, and in most cases the vertical antennal positions were shifted downward. The stimulation also significantly decreased the walking speed of the animal. These behavioral changes imply a careful search in the immediate surroundings. The aftereffect of the sex pheromone was more pronounced on locomotion than on antennal movement. On the other hand, stimulation with the aversive odor (limonene) tended to suppress active antennal movement, and also increased the walking speed. Immediately after the withdrawal of the aversive odor, the active movement of the antennae was resumed, and the walking speed rapidly decreased to a level approximately the same as that of the control period. These results indicate that the responses to the qualitatively opposite types of odor are reciprocal to each other with regard to both antennal movement and locomotion.
