Abstract
A method and apparatus to prepare and deliver a gas mixture of constant composition of liquid chemical compounds soluble in liquid carbon dioxide to be used as an enhanced attractant for biting insects. The mixtures can be prepared in high pressure vessels where carbon dioxide remains liquified under its own vapor pressure or in low pressure vessels where carbon dioxide is kept liquid, at low pressure, by cooling it with a refrigeration unit. Direct vaporization of the liquid mixture from the vessels results in a gas mixture of constant composition. This mixture is to be delivered in a continuous or pulsed flow to an insect trap. These baited insect traps are an ecological alternative to chemical insecticide methods of insect control currently in use.
