Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pheromone trap for attracting and trapping flying pests flying to a field of agricultural crops, a tea plantation, and the like. More particularly, the invention relates to automatically counting trapped pests. Things.

[0002]

2. Description of the Related Art In recent years, with the increasing provision of environmentally-friendly agriculture and the provision of safe crops, it has become necessary to efficiently control pests with a small amount of pesticides. This will lead to a reduction in the price of pesticides as well as environmental issues. In order to effectively control pests, it is not enough to simply spray a large amount of pesticides.
Must be sprayed. Therefore, it is necessary to accurately control the number of pests, and a method of attracting and capturing using a pheromone has conventionally been adopted.

[0003] Initially, the number of pests was visually counted after being attracted and captured by pheromones. But 10 per day
There were many days when more than 00 pests were captured. Counting the number of pests was a daunting task, and counting a large number of pests was a daunting task.

Therefore, an automatic counting device as shown in FIG. 1 has been considered. 1 is a pheromone for attracting pests, 2 is a funnel for guiding pests, 3 is a sensor for detecting pests, 4 is a count tube, and a sensor 3 is provided. Reference numeral 5 denotes a capture container, 6 denotes an insecticidal plate for killing pests flying to the capture container 5, and 7 denotes a counter that counts a signal detected by the sensor 3. The pest is attracted by the pheromone 1, passes through the funnel 2, the count tube 4,
And the gas from the insecticidal plate 6 lowers the flight performance. At this time, the pest is counted by passing through the sensor 3. However, with the gas on the insecticidal plate 6,
Because the complete insecticidal effect takes time, the pests rampage and lepidopterous pests disperse the pollen. The sensor 3 becomes dirty in several hours due to the phosphor powder scattered by the pests, and stops operating.

Recently, a device in which a funnel 8, a baffle plate 9 and an insecticidal plate 10 are further provided in the conventional device (FIG. 1) has been invented as disclosed in Japanese Patent Application Laid-Open No. 7-289137 (FIG. 2). This is because the collision with the plurality of funnels 2 and 8 and the baffle plate 9 and the insecticidal plate 10 prevent the insects from flying before passing through the sensor 3, reduce contamination of the sensor 3, and improve the counting accuracy. To enhance.

[0006]

The conventional apparatus as shown in FIG. 2 requires a plurality of funnels 2 and 8, a baffle 9 and a plurality of insecticidal plates 6 and 9, and has a complicated structure. . In addition, since the flying property is reduced and there are many obstacles, the pests are not smoothly guided to the capture container 5 and accumulate on the way, and do not pass through the sensor 3, so that accurate counting cannot be performed automatically. .

In the conventional device (FIGS. 1 and 2), even when the sensor 3 is not contaminated, the counting by the device and the counting by the human eye are significantly different (the counting by the device is larger than the counting by the human eye). Problem). As described above, since the complete insecticidal effect takes time with the gas from the insecticidal plate, the pests rampage and not only scatter the phosphor powder but also wander around the sensor 3. The sensor 3 senses and counts each time one pest passes many times.

An object of the present invention is to provide a device which has a simple structure and automatically counts automatically, particularly when a pest wanders.

[0009]

Means for Solving the Problems In order to solve the above problems, the present invention takes the following measures. Automatic counting pheromone comprising pheromone attracting means for pests, guiding means for attracted pests, counting means provided with a plurality of sensors in the middle of the guiding means, and insecticide capturing means for killing and capturing the pests trap.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS When a pheromone trap configured as described above is started, a pest is attracted by a pheromone, and the pest is guided to an insect trapping means by a guiding means. During that time, the pests are sensed by two or more sensors, data processing is performed by the processing unit, and the number of the pests in the insecticidal capturing means is automatically counted.

[0011]

Embodiment An embodiment will be described with reference to FIG.
1 is a pheromone, and this pheromone 1 attracts pests. In this embodiment, a pheromone for attracting a male of Chahamaki, one of the three major pests in the tea garden, is attached. 2
Is a funnel provided below the pheromone 1. Reference numeral 4 denotes a count tube which is connected to a lower part of the funnel 2. In this embodiment, a transparent polyvinyl chloride pipe is used for the count tube 4, but glass, acrylic, or the like may be used as long as the sensor can detect the pests passing through the count tube 4.

Reference numeral 15 denotes a capture container, which guides the pest to the capture container 15 by the funnel 2 and the count tube 4. In this embodiment, water (a neutral detergent-containing aqueous solution 11) containing a small amount of a neutral detergent is put into the capture container 15. The neutral detergent has an action of decomposing oils and fats for repelling water on the surface of the body of insects of the order Lepidoptera or general insects, and is effective in losing buoyancy and preventing the insects from rampaging. When the pest falls down the count tube 4 and falls on the surface of the neutral detergent-containing aqueous solution 11, it sinks down to the bottom of the capture container 15 as it is, and the pest does not violate and no scale powder is generated. It is better to raise the water level of the neutral detergent-containing aqueous solution 11 as much as possible in order to reduce the space where the pests escape, and in this embodiment, the distance between the lower end of the count tube 4 and the water surface is set to about 20 mm. It is preferable to add a preservative to the neutral detergent-containing aqueous solution 11 for preventing an odor caused by decay of pests due to high temperatures in summer.

In the count tube 4, a sensor (upper) 12 and a sensor (lower) 13 are installed vertically. In this embodiment, a transmission type photoelectric sensor in which transmission and reception are paired on the left and right is used, but a reflection type sensor may be used. In addition to the photoelectric sensor, the sensor is a capacitance sensor, an infrared sensor,
A radiation sensor, an ultrasonic sensor, or the like may be used. The sensor (bottom) 13 is attached to the end of the counting tube as much as possible. The sensor (upper) 12 and the sensor (lower) 1
In this example, the interval of 3 was 50 mm, but the length of the target insect pest, Chahamaki or Kokakumonhamaki, was 10 mm.
And a distance equal to or longer than the body length of the insect to be captured. In this embodiment, the number of sensors is two, but may be three or more. Reference numeral 16 denotes a processing unit, which is also a power supply unit of the sensor and a control amplifier unit that performs count calculation and output. In this embodiment, the data counted every day is held for about 10 days, digitally displayed at any time, and read on the spot. In addition, a function of acquiring data from a remote place by wire or wirelessly can be added.

Next, a counting method using two sensors 12 and 13 will be described with reference to FIG. In this embodiment, the light passes through the sensor (upper) 12 and further passes through the sensor (lower).
A method was adopted in which a single animal was not considered unless it passed through 13.
In this case, the patterns of Equations 1 to 4 in FIG. 4 can be considered. Equation 1 is when the pest falls from top to bottom,
After passing through the sensor (upper) 12 and passing through the sensor (lower) 13, it is regarded as one animal. The sensor (upper) 12 is turned on until the sensor (lower) 13 is turned on after being turned on, but when the lower is turned on, the count is set to 1 and turned off instantaneously to prepare for the next intrusion. Equation 2 shows that the pest is the sensor (top) 1
2, the sensor (upper) 12 and the sensor (lower) 13
, And waits until it passes (turns on) the sensor (lower) 13. Immediately after passing through the sensor (lower) 13 (ON), it is the same as Expression 1, but may take too long, and the waiting time is arbitrarily set (5 minutes in this embodiment). If the pest does not pass (on) the sensor (lower) 13 even after the waiting time of 5 minutes, the sensor (upper) 12 is turned off, and in this case, counting is not performed. Equation 3 is the case where the pest comes up from below, without passing (ON) through the sensor (upper) 12,
This is the case where the signal passes (turns on) the sensor (lower) 13. It goes up further, and if it passes (ON) the sensor (upper) 12, 1
Although the subtraction method is accurate, it is conceivable that another pest newly enters from above before passing through the sensor (upper) 12 and passes (turns on) through the sensor (upper), which is complicated. Therefore, the count is not performed in the case of Expression 3. Equation 4 is a case where the light does not pass, and the sensor (upper) 12 and the sensor (lower)
13 is off and does not count. The present embodiment is a method in the case where there are two sensors.
It is easy to understand whether you are coming from below, and you can count more accurately.

FIG. 5 shows the measured values of the number of pests Chahamaki caught in September 1997. A is the absolute number visually, B
Is a measured value by the conventional device (one sensor), and C is a measured value by the device of the present embodiment (two sensors). The unit is one animal. B is 2-3 times larger than A, whereas C and A
Was very close.

The values measured by the above-mentioned device can be obtained by the observer who goes to the site by himself / herself and can be obtained from the display of the device or from an electronic memory. You can also. In any case, the power supply of the apparatus can be provided by a power line or by a solar cell. It can also be obtained using the Internet or fax.
