Associative learning has been shown in a variety of insects, including the mosquitoes Culex quinquefasciatus and Anopheles gambiae. This study demonstrates associative learning for the first time in Aedes aegypti, an important vector of dengue, yellow fever and chikungunya viruses. This species prefers to rest on dark surfaces and is attracted to the odor of 1-octen-3-ol. After training in which a dark surface alone or a dark surface with odor was paired with electric shock, mosquitoes avoided the previously attractive area. The association was stronger when odor was included in training, was retained for at least 60 min but not for 24 h, and was equal for males and females. These results demonstrate the utility of a bulk-training paradigm for mosquitoes similar to that used with Drosophila melanogaster.
关联学习已在多种昆虫中得到证实，包括库蚊 Culex quinquefasciatus 和疟蚊 Anopheles gambiae。本研究首次证明了埃及伊蚊 Ae. aegypti 的关联学习能力，埃及伊蚊是登革热、黄热病和基孔肯雅热病毒的重要传播媒介。该物种更喜欢在黑暗的表面上休息，并被 1-辛烯-3-醇的气味所吸引。在训练中，单独的黑暗表面或带有气味的黑暗表面与电击配对后，蚊子会避开以前有吸引力的区域。当气味包含在训练中时，关联更强，至少保留 60 分钟但不保留 24 小时，并且对雄性和雌性蚊子都是平等的。这些结果表明，批量训练范式对类似于 Drosophila melanogaster 的蚊子是有用的。
