摘要: An insect trapping device generates its own attractants of carbon dioxide (CO2), heat and water vapor through catalytic conversion (84) a hydrocarbon fuel in combustion chamber (68). The hot generated the are diluted cooled to temperature above ambient below about 115 ~F by mixing with air, then mixture is exhausted downward exhaust tube (48). A counterflow outside air (52) drawn into trap suction (32) that concentrically surrounds tube. Biting insects captured porous, disposable bag (34) connected other end (36) thermoelectric generator, including modules (102) coupled generate power for fans (38, 64) provide flow flow. Additional chemical may be used make even more effective. adapted different types adjusting airflow velocities attractants.
