JPH03160940A - Insect electrocuting device - Google Patents

Abstract

PURPOSE: To discharge a pheromone and to improve an insecticidal effect by permitting current, blue light beam and ultraviolet rays to flow through the unit. CONSTITUTION: A current source with the sufficient number of volts and amperes for killing insects and a radiation source which is provided with at least two fluorescent lamps for irradiating the blue light beam and the ultraviolet rays with mutually different wave lengths are arranged in a cage shape and a device for intermittently discharging the pheromone is provided as necessary.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric killer for insects. Such electrocutors are used in livestock sheds and houses, for example in old houses. The main insect species that are captured and killed by such electrocutors are the common house fly (house fly) and stable fly (stable fly).
e fly).

The electrokiller consists of a grid structure within which there is a current source of sufficient volts and amperage to kill insects that come into contact with the area. Additionally, there is one fluorescent light that emits blue and ultraviolet light to attract insects. This attraction can be further enhanced by spraying into the heavy killer a pheromone that attracts the genus of insect to be killed. For this purpose, a device for the intermittent release of such phlegmon may be removably mounted in or on the electrocutor.

There are three types of fluorescent lamps available on the market for the electrocution machine, two of which emit light blue light and one which emits darker blue light.

In actual use, it has been found that the percentage of flies actually captured by this type of electrostatic device is the same even when using a combination of fluorescent tubes and pheromone (in this case, the percentage of flies captured is the same as that of pheromone). Although it is higher than without), it has been found that it is often not as high as desired.

We now know that this is because flies have ommatidia. In daylight that contains sufficient UV radiation of the same type as the type of fluorescent lamp in the electroccerator, the relevant ommatidia of the fly's eyes capture a large amount of UV radiation from the daylight, causing the fly to become severely killed. It usually does not react to the light inside the vessel. This means that the flies captured in the electrolyser are mainly flies that entered the electrolyser accidentally.

Based on this perspective, the solution to the problem turned out to be quite simple. According to the invention, the heavy killer has at least two fluorescent tubes emitting blue and ultraviolet light in different wavelength ranges, so that different ommatidia of the fly's eye are activated.

Although more than one fluorescent lamp may be used in the electrocutor, it is preferable to have only two fluorescent lamps emitting blue and ultraviolet light in different wavelength ranges. It is particularly preferred to combine a lamp that emits light blue visible light and a lamp that emits dark blue visible light.

In comparative experiments, the percentage of flies captured by this lamp combination increased dramatically, and even in daylight, the percentage of flies captured increased by more than double.

Although the concept of the present invention may be utilized in an electric discharge device that does not use pheromones, the electric discharge device will work even more effectively if pheromones are used.

Therefore, according to a preferred embodiment, the electrokiller according to the invention further comprises a device for emitting pheromones.

The electrokiller of the present invention has a conventional structure and is preferably combined with a device for emitting pheromones, preferably for intermittent emitting pheromones, to emit blue light and ultraviolet light in mutually different wavelength ranges. There is a novelty in using two or more fluorescent lamps emitting .
