JP2000060402A - Counter for counting number of insect captured by pheromone trap from total weight measured by dial scale - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a counter for counting number of insects captured/killed by a pheromone trap from their total weight measured by a dial scale, capable of accurately determining the number, even when one or more of the captured insects are damaged, because essentially no error is involved in the total weight measured. SOLUTION: This counter counts number, of insects captured by a pheromone trap T, comprising a roof 1 supporting pheromone 2 thereunder, and a main body 3 covered by the roof 1 and containing funnels 4 and 7, a baffle 6 under the bottom opening of the funnel 4, automatic shutter 8 under the bottom opening of the funnel 7 to automatically open or shut the opening, container 9 under the shutter 8 to receive the captured insects, dial scale 10 to weigh the captured insects, and vibration-preventive table 11 to support the dial scale 10 wherein the captured insects are collected in the funnel 7 for a given measurement time determined by controlling a CPU controller 12, and then transferred down to the container 9 by opening the automatic shutter 8 after insect capturing time is over, where their total weight is measured by the dial scale 10.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pheromone based on the amount of flying insects, mainly lepidoptera, flying on agricultural crops and other cultivated crops using an automatic balance. The present invention relates to an apparatus for counting and measuring pests using a trap. 2. Description of the Related Art A conventional flying harmful insect measuring apparatus using a pheromone trap is a counting method in which the total amount of the harmed insects is counted by an optical sensor and the data is recorded. However, as a means of catching, there were many cases where the solids were damaged by electric shock at the time of insect killing, and the measurement of the number of killed was inaccurate. Applicant has obtained patent No. 2
Repeatedly studied and tested the measuring device by 86507,
The present invention proposes a more accurate insect counting device. [0003] The problem to be solved by the present invention is to replace the conventional counting method using an optical sensor mainly based on the number of killed animals with the weighing of the insects caught and killed by pheromone using an automatic scale. The task was to measure the number of killings. Although the conventional electric shock killing means has an error in measurement due to damage, the means of the present invention has a great difference in the effects described later as means for solving this. As means for achieving the above object, an automatic shutter that opens and closes the mouth of the funnel is provided at the lower edge of the funnel provided in the body of the pheromone trap, and an automatic shutter is provided. At the bottom, an automatic weighing device consisting of an automatic weighing device that weighs the amount of insects collected and collected in a tare container and a container for collecting insects is installed, and an automatic shutter and an automatic weighing device are controlled by the CPU. The present invention relates to a pest measuring device using an automatic balance that measures the number of trapped insects based on the amount of insect trapped by the automatic balance at a time. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention.
Pests that damage paddy fields, upland crops, etc. are the same kind of pests (for example, Nikamei moth attached to rice, tea hakimaki attached to tea leaves,
Vegetables and flowers that arrived at the same time in the cutworm, the weight of insects or moths were almost constant (10-30 mg)
) Is known as a pest ecosystem.
Therefore, forecasting the occurrence of pests according to these ecosystems (survey)
If the number of insects captured is recorded based on the total weight of the insects, the number of insects generated can be predicted (surveyed) from the total weight of each of the insects identified in advance. FIG. 1 shows an embodiment of the present invention based on the above-described ecological survey. A pheromone trap T is composed of a sex pheromone 2 attached to the lower surface of an upper roof 1 and a trap body 3 integrally installed below the same. . 3a is a louver. 4 is the first funnel, 5 is the insecticidal plate,
Reference numeral 6 denotes a baffle plate, and reference numeral 7 denotes a second funnel. Reference numeral 8 denotes an opening / closing shutter that is hermetically attached to the mouth of the second funnel. At the bottom of the opening / closing shutter, a tare container (captive catcher) 9 is automatically weighed 1
0 Reference numeral 11 denotes a vibration isolation table fixed to the bottom of the vessel. Openable shutter 8 and tare container 19, automatic balance 1
0, a vibration damping table 11 is a printer 15 that measures the amount of insects trapped in the insect catcher as a tare at the measurement time specified by the timer 13 of the power supply 14 by the CPU control device 12 and records the amount.
It operates as an automatic weighing device equipped with. 16 is a relay, g
Is a ground plane. FIG. 2 shows a second embodiment in which the intermediate container of the second funnel is omitted. The pheromone trap T2, the roof 17, the pheromone 18 on the lower surface of the roof, the body 19 set on the lower part of the roof, and the first funnel 20, 21 Insect-killing plate suspended on the hanger 22, 23 is insect repellent, 24 is a shutter at the lower part of the funnel, 25 is a tare container for catching and killing insects 26 (insect catcher), 27 is a louver, 28 is an automatic weigher, and 29 is a remover. It is a shaking table. The structure of the trap body is appropriately changed within the scope of the claims. In the measurement by the measuring device of the present invention, the amount of insects trapped in a measuring time specified in advance by a timer is counted by a timer according to the time zone in which the insect flies under the central control of a CPU device provided outside the body of the automatic weighing device provided under the trap body. I do. An example of the operation is shown in FIG. 3, but before the measurement, the operation function of the scale is stabilized by the signal from the timer, and the balance of the tare container for catching insects (the weight of the insects collected before ) Is automatically adjusted. The insecticidal amount of the pests captured in a specific measurement time per day (for example, 7:00 am) is collected in an intermediate container with a shutter and the shutter is opened after the capture time is over, and the shutter is opened to measure the pests (a tare for catching insects). ) And store the measured values in memory. The treatment and cleaning of the insects collected in the catch catcher (tare) is necessary in order to maintain the measurement accuracy in practice. According to the present invention, the present invention is an apparatus for measuring the amount of pests trapped by the above-described trap, and does not need to collect a large amount because it is not a pest control device. The workability is easy and effective in practice. Prediction (investigation) of pest outbreak is possible if even small amounts can be collected in synchronization with the pest incidence. In other words, it is assumed that 50 mg of insects per animal can be collected at a time on average, and the weight of the tare is added, and even if the weight of the tare is added, the measurement can be performed 100 to 300 times by a general automatic weighing device of 200 to 300 g. It becomes possible. In addition, the conventional means of killing by electric shock has many errors in the number of kills as described in [0002], but according to the apparatus of the present invention, even if the insects are damaged by the electric shock, the error in the weight measurement as a whole does not. Since it hardly changes,
It has a great advantage as a measuring device and its utility is extremely large.
