A cylindrical, collapsible, and economical field cage for mosquito research.

A new cage was designed to study caged mosquitoes in ultra-low volume insecticide spray studies in the field. Insecticide droplets may enter the cage from any direction because all surfaces are mesh. Cages can be collapsed in seconds, and reassembly is quick and simple. A 26-cm-diam cage can be constructed for less than US$6.00.
