研究了双斑蟋蟀嗅觉记忆保持的时间跨度。第三或第四龄的若虫蟋蟀被训练将一种气味与水联系起来，将另一种气味与盐溶液联系起来。在训练后6周和10周，成年蟋蟀表现出明显更大的偏好与水有关的气味与盐水溶液。训练后6周进行逆转训练时，习得的偏好发生了改变。我们的结论是，蟋蟀能够保留嗅觉记忆几乎为他们的一生，很容易改写它根据经验。
The time span of olfactory memory retention in the cricket Gryllus bimaculatus was studied. Third- or fourth-instar nymph crickets were trained to associate one odor with water and another odor with saline solution. At 6 weeks and 10 weeks after training, adult crickets exhibited significantly greater preferences for the odor associated with water over that associated with saline solution. The learned preference was altered when they were given reversal training at 6 weeks after training. We conclude that crickets are capable of retaining olfactory memory practically for their lifetime and of easily rewriting it in accordance with experience.
