Abstract
Earlier types of suction sampling apparatus, driven by electric or petrol motors, are briefly reviewed and their disadvantages for work in remote areas indicated. To overcome these a cheap, simple, hand-operated model has been developed and the construction of this is described. However, unlike some of the motorised models, it does not extract all the fauna from the area sampled.
