The aspirator (fig A), known in England as a ‘pooter,’ is a convenient and effective device for collecting small insects and mites. The following materials are needed to construct an aspirator:
(1) Vial 2.5-5 cm in diameter and about 12 cm long.
(2) Two pieces of glass or copper tubing about 7 mm in diameter, one piece about 8 cm long and the other about 13 cm long.
(3) Rubber stopper with two holes in which the tubing will fit snugly.
(4) Piece of flexible rubber or plastic tubing about 1 meter long, with diameter just large enough to fit snugly over one end of shorter piece of stiff tubing.
(5) Small piece of cloth mesh, such as cheesecloth, and rubberband.
