Berlese Funnel Trap
BioQuips standard Berlese funnel is an effective device used for extracting small insects and spiders, or larvae of boring insects from forest litter, dry wood, or infested branches.
The portable unit is fabricated around a 3-1/2 gallon sturdy polypropylene bucket. A lightweight, spun aluminum funnel rests on the buckets rim. The funnels smooth surface may be waxed and polished if desired. A 1/4″ wire mesh screen inside the funnel supports the litter from which specimens are collected. An AC electrical socket for use with a 25-watt light bulb is mounted on the underside of the spun aluminum lid. A six-foot self-polarizing electrical cord contains a rotary on/off switch. Heat generated by the lamp dries out the material, and specimens drop down through the screen into a collecting jar or container of alcohol. (Light bulb and jar are not included.)
The Berlese funnel has a 12″ (30.5 cm) diameter, is 14″ (35.6 cm) high, and weighs 3 lb., 4 oz.
BioQuip suggests using #2830 heat packs for collecting in areas where electricity is inconvenient or not avvailable.
