The aspirators are one of the main components to work with insects. This collection shows a variety of aspirators for all your requirement i.e, to collect manual to mechanical and small to large insects from easy to difficult to reach areas. The simplest ones are mouth operated and more sophisticated are semi-automated using pressure bulb and automated mechanical -a battery operated. The aspirators are classified into several groups based on the design, working principle and diameter of the collection tube. The diameter of the insect pick-up straws is 6mm or 8mm or 12mm. The bigger-size mouthed straws should be selected for bigger insects and smaller-sized mouthed one for the smaller/tiny insects, for example, aphids, whiteflies, etc. We have mechanical aspirators to collect fruit flies from trees.
