A versatile wind-resistant insect cage
Abstract
Ecological field studies often require cages that can withstand adverse weather conditions such as high winds, without greatly altering environmental conditions within them. A large field cage was designed, fabricated and tested for predator-prey studies on raspberry plantings. It consisted of a wood base and screening suspended with loops of canvas from a framework of PVC pipe. The cage withstood gusts above 70 km/h, did not appreciably alter temperature or RH, but did reduce light by 40% and rainfall by 25%. The cage design is simple and can be adapted to many experimental situations.
