ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a method and apparatus for dispensing an insect attractant such as carbon dioxide along a pipeline. The invention further relates to a method and apparatus for releasing carbon dioxide gas into insect traps for purposes of capturing and/or exterminating insects.
BACKGROUND OF THE INVENTION
Flying and biting insects are presently controlled by the application of insecticides directed either at immature stages (larvicides) or adults (adulticides). These compounds are generally applied as a broadcast spray from either the air or the ground. This broadcast application generally results in two levels of failure. First, large areas of land and water are treated where there are no insects. Second, non-target, beneficial organisms are oftentimes affected and sometimes killed by the broadcast treatment.
Solid CO
2
(dry ice) has been used as an attractant for flying and biting insects insects to gather data about this insect population density. This data has been used to aid in determining when broadcast application of insecticides is needed, and in what amounts. While dry ice has been effective as bait for insects because it sublimates CO
2
gas into the atmosphere, there have been no effective methods of metering the amounts of CO
2
gas released from a source of CO
2
for attracting insects.
SUMMARY OF THE INVENTION
In light of the foregoing, a need exists for a way of more accurately targeting insects for extermination or capturing without adversely affecting the surrounding environment.
A need also exists for a way of more accurately targeting insects for capture extermination and/or capture without exterminating/capturing unintended organisms.
According to one aspect of the present invention, a system for attracting an insect population comprises a source of chemical attractant for insects, a distribution feed tube in fluid communication with the source, a controller for controlling the flow of attractant from the source through the distribution feed tube, and at least one target in fluid communication with the distribution feed tube, the target including means for effecting, when an insect comes into contact with the target, capture of the insect and extermination of the insect.
According to another aspect of the present invention, a target for trapping and/or exterminating insects comprises a support structure, a surrounding element mounted on the support structure for defining an interior space within the surrounding element, means provided on the surrounding element for effecting at least one of capture of an insect that comes into contact with the surrounding structure and extermination of an insect that comes into contact with the surrounding structure, and a tube extending into the interior space of the surrounding structure for introducing CO
2
containing gas into the interior space to attract insects into coming into contact with the surrounding structure.
According to yet another aspect of the present invention, a process for attracting an insect population to a target comprises the steps of providing a system for capturing or exterminating and/or capturing insects, flowing primary chemical insect attractant from said source through said distribution feed tube to said at least one target, controlling the flow of said primary chemical insect attractant with said controller, and contacting insects with said means for either capturing or exterminating.
According to yet another aspect of the present invention, a controller for controlling the mixture and distribution of a primary chemical insect attractant comprises 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.
Still other objects, features, and attendant advantages of the present invention will become apparent to those skilled in the art from a reading of the following detailed description considered with reference to the accompanying drawings.
