Method and delivery system for the carbon dioxide-based, area specific attraction of insects
First Claim
1. A target for exterminating and/or capturing insects, comprising:
- a support structure;
a surrounding element mounted on and surrounding the support structure, said surrounding element having an interior space;
means provided on the surrounding element for effecting at least one of capture of an insect that comes into contact with the surrounding element and extermination of an insect that comes into contact with the surrounding element;
a tube extending into said interior space of said surrounding element for introducing a gas containing CO2 into said interior space to attract insects into coming into contact with said surrounding element;
means to prevent passage of said insects into said tube; and
wherein said surrounding element comprises a fabric covering which is impregnable with a contact insecticide, coatable with a film of oil to maintain a tacky surface, or both.

Abstract
A method and delivery system for an area-specific precision control of biting insects, including flying and non-flying, biting arthropods, is described. CO2 is metered through a tubing fence and dispensed into the center of traps that serve as visual targets for flying or walking biting arthropods. The outside membrane of a trap can be treated with mineral oil to capture and kill small arthropods such as sand flies of the genus Culicoides, or black flies of the genus Simulium. In addition, the membrane can be treated with insecticide formulations of Permethrin, Resmethrin, or Deltamethrin, to kill larger biting arthropods, such as ticks, mosquitoes, deer flies, horse flies, or stable flies. This method for biting arthropod control is an ecological-friendly alternative to the widespread broadcast application of organophosphate insecticides such as Derspan, Diprom, and Maithion.

14. A controller for controlling the mixture and distribution of a primary chemical insect attractant and a secondary chemical insect attractant, comprising:
-
means for conducting a flow of said primary chemical insect attractant; switch means for determining whether the flow rate of said primary chemical insect attractant through said conducting means has exceeded a predetermined limit value, said switch means comprising timer means for evaluating the time elapsed while there is flow in said conducting means, said switch means generating a limit control signal; valve means, in control signal communication with said switch means and responsive to said limit control signal, for allowing flow of said primary chemical insect attractant through said conducting means when open and substantially stopping flow of said primary chemical insect attractant through said conducting means when closed; said switch means controlling said valve means with said limit control signal to close when either said timer means indicates that a predetermined time has elapsed or flow in said conducting means exceeds a predetermined level; primary flow meter means, in fluid communication with and fluidly downstream of said valve means for metering the flow of said primary chemical insect attractant through said conducting means; a source of secondary chemical insect attractant; secondary flow meter means for metering the flow of said primary chemical insect attractant and said secondary chemical insect attractant, said source of secondary chemical insect attractant and said secondary flow meter means in parallel flow communication with said primary flow meter means; and means for mixing said primary chemical insect attractant and said secondary chemical insect attractant. - View Dependent Claims (15)
