  • Patent number: 4410967
    Abstract: A unique method for detecting and sampling flying insect populations is disclosed. An agricultural area is baited with a specific sex pheromone of a specific flying insect. When the flying insect is lured into range of the bait, a low-frequency sound is transmitted into contact with the insect. The sound is received in a counting means and the detection of the insect stored. Accumulated detections over a period of time form a population sampling of the insect studied.
