Description

  The present invention relates to an insect trapping apparatus for trapping harmful insects, and more particularly to an insect trapping apparatus for trapping insects by combining airflow and light irradiation.

  Conventionally, insecticides composed of various agricultural chemicals are generally used as a method for controlling insects such as vegetables. However, depending on the type of vegetable, there are cases where there are few pesticides effective against adhering pests, and the insecticidal effect of pesticides is low against difficult-to-control pests that are drug resistant. Recently, residual pesticides have become a problem due to consumers' safety and health consciousness, and demands for pesticide-free and reduced pesticide cultivation are increasing.

  There are methods to control pests without using pesticides, such as using natural enemies and using copulation inhibitors (pheromone agents), but even if these are used alone, the control effect is low compared to pesticides. There is a problem that must be used in combination with agricultural chemicals.

Therefore, recently, pest control devices that capture and control by a physical method without using pesticides have been proposed. One of them is an ultraviolet trapping device (for example, Patent Document 1). This utilizes the property that insects are strongly attracted to ultraviolet rays, attracts insects with UV lamps, and kills insects with adhesive plates, water basins, suction fans, and the like. In addition, as disclosed in Patent Document 2, there is a suction type insect trapping device in which exhaust air from a suction pump is blown out to a plant body, and pests are blown away and sucked.

  The ultraviolet ray trapping apparatus as in Patent Document 1 can attract a wide range of pests at night, and can obtain a practically sufficient insect trapping effect. However, since the irradiation intensity of the UV lamp is too small compared to sunlight in the daytime, the attracting effect can only be exerted on pests in the immediate vicinity. For this reason, an ultraviolet insect trapping device has not been an effective control device for thrips, leafhoppers, and whiteflies that are diurnal difficult-to-control insects.

  In addition, as in Patent Document 2, an insect trapping device that blows and sucks insects by exhaust cannot obtain a sufficient trapping effect on insects that are not exposed to exhaust with sufficient strength, such as behind the leaves. was there.
