JP2000060403A - Automatic counter for counting number of flying harmful insect, including lepidopteron, captured by pheromone trap - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a counter for counting number of flying insects captured by a pheromone trap, which improves the trapping effect by guiding the insects lured into the trap to the insecticidal section by a light source set within a baffle under a funnel. SOLUTION: This counter counts number of insects captured by a pheromone trap 1, comprising a main body 2 covered by a roof 3 which supports pheromone 3 thereunder. The main body 2 contains a funnel 5 to which an insecticidal plate 6 is attached; baffle 7 under the funnel 5, to the lower side of which a baffle device is attached to lure the insects into the baffle 7 by light with luminosity and brightness sufficiently low not to be projected to the outside; and insect-receiving box 10 in the lower section of the main body 2 to collect the insects killed in an insecticidal section 8. Number of the captured insects is counted, while they are dropped into the insect-receiving box 10, by an optical sensor 11 set under the baffle 7. The baffle device may comprise one or more light-emitting diodes attached to the lower side of the baffle 7, made of a transparent material, e.g. plastic.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic counting apparatus for predicting the occurrence (survey) of lepidoptera and other flying pests flying on rice and other crops. 2. Description of the Related Art Lepidoptera and other flying pests related to cultivated crops such as rice, tea, fruit trees, and the like are provided with means for predicting (investigating) the occurrence of the pests. In recent years, many experiments and apparatuses have been provided as a method for investigating pests as an attractant as an effective means for predicting and killing and controlling pests. The applicant also proposed a registered patent No. 286507 shown in FIG. 4 as a technical manufacturer in the art, and killed the pheromone f via the baffle plate g with the insecticidal plate c mounted in the body b of the trap a to which the pheromone f was attached. A print-type pheromone trap device that automatically counts the pest w with the optical sensor s below the funnel d and stores the data is implemented as an effective means device. Other methods for investigating the occurrence of pests include Japanese Patent Publication No. Hei 4-62695 and Japanese Patent Laid-Open No. Hei 5-15828.
Nos. 4 and 5-15285. However, the trap using the pheromone proposed by the applicant has been used as an effective pheromone trap which achieves a certain result in its accuracy and structural function by the counting and investigating method by collecting and killing flying pests. However, pheromone traps can be attracted by pheromone depending on the kind of insect, but there is an escape phenomenon in which they escape again without entering the funnel (capture part) provided inside the trap body, and they can perform their functions sufficiently. May not be. [0003] An object of the present invention is to provide a counting device using light together with a new trapping means in addition to a conventional insect trapping means using a pheromone trap. did. In order to achieve the above-mentioned object, as a means for achieving the above-mentioned object, a pest attracted to the inside of the insect trap by a pheromone trap is not projected on the inner surface of the baffle plate provided near the lower part of the funnel, but flies to the upper part. A means for solving the problem was to attach a weak light source enough to enter the pest's eye when the insect was pested, capture the pest attracted to the insecticide part of the insect trap in the vessel, and count the insect. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention.
FIG. 1 shows a first embodiment, FIG. 2 shows a second embodiment, and FIG. 3 shows a third embodiment. First, the first embodiment will be described. A pheromone trap 1 installed on an installation surface g such as an outdoor farm is described.
Attaches a sex pheromone 4 to the lower surface of a roof 3 attached to the upper part of a cylindrical (circular, square) body 2. In the vessel, a first funnel 5 is provided at an upper portion and a second funnel 9 is provided at a lower portion. An insecticidal plate 6 made of an insecticidal DDVP fumigant or the like is attached to an outer wall of the first funnel. Reference numeral 7 denotes a mountain-shaped baffle provided near the lower portion of the first funnel so that the pests entering the insect killing section 8 in the body do not escape out of the vessel. The baffle plate 7 is a baffle plate device formed of a transparent material such as plastic and having an LED (light emitting diode) mounted inside. The illuminant may be a fluorescent lamp or a portable miniature lamp in addition to the LED. The color may be blue, yellow, or white. The illuminant to be illuminated is not visible from around the body of the trap, but penetrates the transparent material of the baffle plate and configures the luminous body and baffle plate so that when the pest comes directly above, it enters the pest's eyes and disturbs the pest Attract in the board. As an embodiment in which an LED is mounted, a luminous intensity (cd) power supply voltage of 3.6 V, an LED voltage of 2 V to 5 V, and a current value of 8.0 mA (yellow LED) to 2
An illuminance (Ix) within a range of brightness by a weak power supply / voltage of 5 mA (blue LAD) is appropriate. Regarding the illumination color, in the case of a fluorescent lamp, a blue fluorescent lamp that emits blue-violet light having a wavelength of 470 nm, which is most easily perceived by moths, has an excellent attracting effect. The luminous intensity and the illuminance are not limited to the examples, and the design is appropriately changed depending on the installation place, the type of the pest, or the structure of the trap. 9
Collects the pests caught in the insecticide unit 8 by the second funnel in the receiving box 10 provided at the bottom of the lowermost body. Reference numeral 11 denotes an optical sensor for counting the number of captured pests falling into the receiving box. FIG. 2 shows a second embodiment of the body device of the pheromone trap, which is a pest return formed of transparent plastic on the upper part of the first funnel 14 so as to prevent the invading insects attracted by the pheromone of the roof 13 of the body 12 from returning. The stop plate 15 is installed, and the light of the LED (light-emitting diode) 17 installed at the vertex of the baffle plate 16 is reflected downward instead of scattered outward, so that the light from the LED (light-emitting diode) leaks out of the device. Install the pests so that they do not escape outside. 18
Is a second funnel. FIG. 3 shows a third embodiment in which a fluorescent lamp 20 is installed, and a small-sized opaque plate for shielding the apex inside the apex of a transparent baffle 22 installed in a first funnel 21 of a pheromone trap 19. 24, and assembled so that the illumination of the fluorescent lamp 20 is reflected from the upper part of the first funnel and does not leak outside. Reference numeral 25 denotes an insecticide part, and reference numeral 26 denotes a second funnel. As described above, the present invention improves the conventional flying insect pest trapping device using a pheromone trap and provides a baffle plate device using light (illumination) in combination with the pheromone trap. The present invention provides means for further enhancing the insect trapping effect by means of a device having a tendency to attract water.
