描述了一种带有旋转转盘的实验笼，它允许在实验室中进行宿主偏好研究，并产生与现场研究一致的结果。测试人群的规模和组成可以控制，条件标准化，提供优于实地研究的优势。利用该实验笼和粘滞型诱捕器，表明埃及伊蚊（Aedes aegypti（L.）无论体重比大小，跗库蚊都偏爱小鼠，而仅当体重比为小鼠2倍时，才偏爱鸡，其余时间无偏爱性。C.跗跖螨喜欢青蛙、蟾蜍和蜥蜴，但更喜欢老鼠或小鸡。A.埃及人不喜欢冷血动物。
本文介绍了一种用于收集动物气味的冷冻捕集技术，该技术能够使气味与二氧化碳非化学分离。使用这种技术，发现小鸡和老鼠的气味对两种蚊子都有吸引力，但活老鼠比老鼠的气味更受欢迎。人类前臂的气味对A的吸引力埃及鸡宝宝的气味。没有发现来自青蛙或蜥蜴的吸引人的气味。当等量的老鼠气味和小鸡气味出现时，蚊子无法区分。在所有其他因素相同的情况下，蚊子更喜欢最丰富的气味。
在小鼠气味中加入CO_2可增加其对A.埃及人。A没有表现出偏好。埃及伊蚊对小鼠气味加小鼠CO2量或小鸡气味加小鸡CO2量的反应。带有小鸡气味的二氧化碳释放速率比带有老鼠气味的二氧化碳释放速率快2.5倍。对于.埃及CO2是有吸引力的，但是一旦达到CO2的低阈值水平，添加更多的CO2不会引起吸引力的增加。
An experimental cage with a revolving turntable is described which permits host preference studies to be conducted in the laboratory and which yields results agreeing with field studies. The size and composition of the test population can be controlled, and conditions standardized, providing advantages over field studies. Using this experimental cage and sticky type traps, it was shown that Aedes aegypti (L.) preferred mice to chicks regardless of the weight ratio, while Culex tarsalis Coquillett only preferred the chicks when their weight was 2× that of the mice, otherwise showing no preference. C. tarsalis was attracted to frogs, toads, and lizards, but preferred mice or chicks. A. aegypti was not attracted to cold-blooded animals.
A freeze trapping technique for the collection of animal odors which enables nonchemical separation of odor from carbon dioxide is described. Using this technique, it was found that chick and mouse odor is attractive to both species of mosquitoes, but that live mice are preferred to mouse odor. Human odor from the forearm is as attractive to A. aegypti as baby chick odor. No attractive odor from frogs or lizards was found. The mosquitoes were unable to distinguish mouse odor from chick odor when present in equal amounts. With all other factors being equal, the mosquitoes preferred whichever odor was the most abundant.
The addition of CO2 to mouse odor increased its attractiveness to A. aegypti . No preference was shown by A. aegypti for either mouse odor plus mouse amounts of CO2 or chick odor phis chick amounts of CO2. The carbon dioxide with the chick odor was released at a rate 2.5× faster than that with the mouse odor. For A. aegypti CO2 is attractive, but once a low threshold level of CO2 is reached the addition of more does not cause increased attraction.
