DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the investigation of occurrence of lepidopteran and other flying pests and the use for collecting and killing them.

[0002]

[Prior art and its problems] For insect damage to crops, etc. caused by lepidopteran and other flying insects, the method of investigating the occurrence status of insect pests by using sex pheromone (hereinafter referred to as pheromone) as an attractant is to predict and control insect pests. In recent years, many experiments and devices have been provided as effective means, and as a method for investigating the occurrence thereof, means such as an adhesive type, a live trap type, an electric shock type, an insecticidal type, and a basin type have been developed. Then, a counting investigation was carried out by collecting and killing the harmful insects by these devices, and Japanese Examined Patent Publication No. 4-62695, Japanese Unexamined Patent Publication No. 5-15284 and 5-15.
No. 285 and No. 5-15286. However, these means have the problems that they require human labor for visual inspection, lack workability, and have many counting errors due to breakage damage of individual insects. Further, the structure generally used as the conventional structural type is such that the vessel 2 is installed under the roof 1 in which the pheromone f of FIG. 4 is set, and the counting glass tube 4 is provided under the funnel 3 provided inside the opening of the vessel.
There is a pheromone trap in which a light emitting portion and a light receiving portion of the sensor S are provided on both sides of the glass tube, a drawer 5 in which an insecticidal plate 6 is set is housed at the bottom of the body, and the sensor is connected to an automatic counter 7. As shown in FIG. 5, a lower body 2 of the roof 1 is provided with an electric shock insecticide 8, or as shown in FIG. 6, there is a visual device having an adhesive coating belt 9 at the lower part of the funnel, which is attracted by a pheromone. There is a foreign case where the pests have a flying property that is reduced by the gas from the insecticidal plate and pass through the counting glass tube at the bottom of the funnel and fall to the bottom of the body, but it takes about 30 minutes for the complete insecticidal effect. Therefore, in the meantime, there are problems with the flight of insects, the vertical movement of the glass tube peripheral wall, etc., and the work effort of the investigation time.In addition, even in the electric shock type, the safety due to high voltage and the number of individuals due to division damage of pests There is a problem in counting accuracy, and improvement of these is desired as a problem in function and structure of the trap.

[0003]

The problem to be solved by the present invention is that the flying ability depends on the type of flying pests attracted into the body as a counting processing means for approximating the number of captured harmful insects and the actual count number. Another object was to solve the problem by improving the structural device that suppresses the wandering movement to eliminate the error in counting accuracy and labor saving in counting work.

[0004]

As means for achieving the above object, a pheromone agent attached to the roof is provided with a baffle plate, and a body provided with an insecticidal plate and a louver is provided below the roof. A plurality of funnels with different inclinations in the body, and a mountain-shaped baffle plate interposed between the funnels are installed in the counting glass tube and glass tube that are closely attached to the lower end of the bottom of the funnel. The gist of the present invention is a pheromone trap with automatic counting and printing of scales and other flying pests, which is provided with a counting sensor and a collecting and killing box in which an insecticidal plate is laid at the bottom of the body.

[0005]

[Function] The baffle placed near the pheromone installed on the roof is properly attached or detached depending on the type of the pest, and the pests attracted inside the body are hindered from flying by a plurality of funnels and the collision action on the baffle. In addition, the flight wandering ability is reduced in combination with the effect of the insecticidal plate, the floating and movement in the counting glass tube are suppressed, and the weight of the counting glass tube is dropped by its own weight to improve the accuracy of the counting number by the sensor. Further, the louver prevents the rise of the temperature inside the vessel due to ventilation, and prevents the deterioration of the semiconductor element of the optical sensor. In addition, the diameter of the glass tube is enlarged to reduce the polluting effect of the insect powder on the sensor,
Moreover, the rate of hitting the optical axis of the sensor due to wandering of pests is reduced.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. The trap device of the present invention comprises a roof 11 and a vertically elongated body 15 provided near the lower part of the roof in FIG. A horn-shaped body is suitable as the body. The roof is screwed to the upper part of the body with bolts 12 and its height is adjusted appropriately. 13 is a sex pheromone attached to the bottom of the roof to attract insects.
Is a cross-shaped baffle that is surrounded by it and invites the collision and fall of insects flying depending on the type of insect, and is removable. At the opening of the body 15 close to the lower part of the pheromone, a first funnel 16 attached below the body forms a steep angle so that insects entering the body from the funnel do not escape to the outside of the body. 17
Is an insecticidal plate attached to the outer wall and is made of an insecticidal DDVP fumigant or the like. Reference numeral 18 is a mountain-shaped baffle plate provided near the lower portion of the first funnel, and 19 is a second funnel. Both are effective against insects with strong flying properties. S is an optical sensor. The second funnel is inclined more gently than the first funnel, and the baffle 1
The insects capable of flying together with 8 directly fly around the counting glass tube 20 to which the optical sensor S is attached so as not to interfere with the counting function of the sensor. Reference numeral 21a is a drop guide that can be replaced so as not to be off the optical axis depending on the type and size of the pest. The counting glass tube is provided in close contact with the periphery of the second funnel opening, and the light emitting portion 22a and the light receiving portion 22b of the optical sensor S are connected to the lower portion of the counting glass tube to the automatic counter device 23 outside the mounting device. Reference numeral 24 is a heat radiation louver. At the bottom of the body under the counting glass tube 20, a receiving box 25 with an insecticidal plate 17 is set. 26 is an outlet. In addition to the optical sensor, a capacitance sensor, an infrared sensor, a radiation sensor, or the like can be used for the investigation of the occurrence of organisms such as pests.

FIG. 2 shows a second embodiment of the present invention in which a first funnel 31 having an opening portion and a second funnel 32 having a lower portion therein are provided in a body 15.
A third funnel 33 is provided at the bottom, and a mountain-shaped baffle plate 34 is installed between the second funnel and the third funnel. Depending on the type of flying insects, insecticide plates 17 are added to the upper part and the middle part for large insects having high flight properties and chemical resistance, and the number of funnels is increased to partition the flight space and disturb the flight capability. Regarding the structure of the funnel, in addition to the first embodiment, the flat funnel plates 35 and 36 of the second embodiment 31, 32 and 33 are attached in a cross shape as shown, and one funnel plate 35a is attached to the other funnel plate 36. The insects may be projected upward below to prevent the rising insects from wandering around.

[0008]

[Effect] As described above, the structural device of the present invention has the function of eliminating the drawbacks of the conventional pheromone trap and significantly reducing the flight ability of flying pests and the durable structure, so that the counting accuracy is improved and the counting operation is automated. By doing so, labor saving can be achieved, and a remarkable effect that is useful for investigation, collection and killing of pests can be expected. In addition, by automating the outbreak investigation, the count value of a certain time zone can be incorporated into a computer as data, and information on the occurrence of pests and the advantage that it can be used for accuracy of accuracy, online remote control occurrence investigation, or solar use as a future prediction It is fully possible.
