该昆虫捕获器与一定容积的样品空气相连，以为昆虫提供相应的不受天气或一日内不同时间条件影响的空气浓度。该捕获器可以根据预设的计时进行分离操作以显示昆虫的飞行周期。间隔计时为5分钟至1小时。其它定时操作也可按要求供应。该套设备也可选用不配备圆片垂落机制式的，采样器可通过边缘溢出口将样品吸入塑料容器内。
Johnson and Taylor insect suction trap
| For correction factors for wind speed and insect size see Taylor (Ann. appl. Biol. Vol. 50, pp 405 - 421). The catch is segregated at pre-set time intervals (min.-hours) to show flight periodicity.
