An Insect Activity Monitor was created to measure the behavioural responses of fleas (Siphonaptera). The apparatus allows for a range of visual, chemo- and mechanoreceptor cues to be presented. The jumping response is detected by counting amplified pulses produced as the fleas land on a stretched membrane held over a microphone. Horizontal movements are detected using a system of infra-red beams and phototransistors which, when broken, are counted as a measure of activity. The apparatus was tested using Ceratophyllus hirundinis (Curtis), Ceratophyllus farreni (Rothschild) and Ceratophyllus rusticus (Wagner), co-inhabiting species from the nests of the house martin (Delichon u.urbica L.). No unaided emigration or immigration has been demonstrated in these species (Clark, 1988) and much of their time is spent confined to the darkness of the nest. In addition to species contrasts, females were more active than males and fleas were more active at 25 degrees C than at 18 degrees C. The more active bird flea Ceratophyllus garei (Rothschild) from the nest of pheasant (Phasianus colchicus L), was tested for responses to light of varying intensity. Activity was stimulated by white light, but not proportional to light intensity.
一种昆虫活动监测器被制造出来用于测量跳蚤（蚤目）的行为反应。该仪器能够呈现一系列视觉、化学和机械感受器线索。当跳蚤落在置于麦克风上方的拉伸膜上时，通过对放大的脉冲进行计数来检测跳跃反应。水平运动通过一个红外光束和光电晶体管系统来检测，当光束被打断时，计数结果作为活动量的一种度量。该仪器用燕巢蚤（柯蒂斯）、法氏巢蚤（罗斯柴尔德）和粗巢蚤（瓦格纳）进行了测试，这三种跳蚤共同栖息于家燕（家燕）的巢穴中。在这些物种中尚未证实有自发的迁出或迁入行为（克拉克，1988），并且它们大部分时间都局限于巢穴的黑暗环境中。除了物种差异外，雌性比雄性更活跃，并且跳蚤在25摄氏度时比在18摄氏度时更活跃。对来自雉鸡（环颈雉）巢穴中更活跃的鸟蚤加氏巢蚤（罗斯柴尔德）进行了不同强度光照反应的测试。白光能刺激活动，但与光强度不成正比。
