ATTRACTING DEVICE, INSECT TRAPPING DEVICE AND INSECT TRAPPING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an insect trapping device capable of efficiently attracting insects on the basis of their behavior.SOLUTION: As a result of using polarizers 231, 232 having different vibration directions, an edge is formed on a boundary between the polarizers 231, 232 by a longitudinal polarized light whose vibration direction is a vertical direction and a horizontal polarized light whose vibration direction is a horizontal direction, thereby effectively attracting a harmful insect. In addition, an attracting device 13 can be used as an inexpensive and safe lighting device because wavelength of a light source to be used for the lighting device is not limited, so that the device can be made low-cost and general-purpose.
