Abstract

PROBLEM TO BE SOLVED: To provide a mosquito killing device for preventing occurrence of mosquitoes by shutting mosquito larvae in a vessel and killing mosquitoes in the stage of larvae without bringing adult mosquitoes outside the vessel even after adult mosquitoes emerge from the larvae. SOLUTION: This mosquito killing device comprises a vessel 1 provided with a plugged drain port 2 and a vent hole 3, a funnel-shaped guiding cylinder 4 mounted in an opening of the vessel 1, and a conical guide member 5 whose top is fitted to the outlet opening of the guiding cylinder, in such construction that the guide member 5 is fitted to the bottom of the vessel 1 with a clearance through which mosquito larvae can pass and that the vessel is filled with water to make mosquitoes oviposit in the water, so that the hatched mosquito larvae is introduced into the vessel and shut in the vessel.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides an laying place for mosquitoes by placing them outdoors and capturing them at the stage of larvae to eliminate mosquitoes.

[0002]

2. Description of the Related Art Conventionally, there has been no device for directly capturing larvae's bow hula, which had been used to control mosquitoes.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a container for preventing the generation of mosquitoes which are killed in a bowl when they are trapped in a container and become mosquitoes and do not go out of the container. .

[0004]

According to one aspect of the present invention, a funnel-shaped guide cylinder is fitted to an opening of a container provided with a plug and a drain port and a vent hole. Another feature of the present invention is that the top of the conical guide plate is inserted into the outlet and is attached to the bottom of the container with an interval enough to allow passage of the bowl. It is characterized in that two guide plates facing the opening of the container provided with the pores are attached so that the gap between the two guide plates can be changed so that the bowl can pass therethrough.

[0005]

According to the present invention, mosquitoes lay eggs in shaded puddles and annihilate the larvae's bow hula mainly by using the behavior of up-and-down movement. The bow hula is a narrow and narrow funnel-shaped outlet within the range of the vertical movement while repeating the vertical movement (b)
There is water, air and light in the container, and the container moves up and down as before and turns into a pupa and emerges as a mosquito without searching for an outlet, but there are no outlets on the water surface Dies in days. The drain is to flush out dead mosquitoes with water,
The vent hole is always the same as the water level in the container because the water in the container flows out even if the water in the guide tube (plate) evaporates. Therefore, if the amount of water in the container is increased, it can be used for a long time without refilling water.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments shown in the drawings will be described below.
In the invention shown in FIG. 1, a drain (2) provided with a plug (a) having a vent hole (3) is provided in a container (1) made of plastic or the like, and a funnel-shaped guide cylinder (4) is provided in the opening of the container. ) Is inserted into the outlet (b), and the top of the guide plate (5) having a conical shape is inserted into the outlet (b), and is attached to the bottom of the container with an interval enough to allow passage of the bowl. As a result, the outlet is in a donut shape.Therefore, it is possible for a plurality of outlets to flow out of the container along the induction board at a time. This is to prevent them from returning inside. In the invention of FIG. 2, a drain port (2) provided with a plug (a) having a vent (3) opened in a container (1) is provided, and two opposing guide plates ( 6) is attached to the lower gap so that mosquitoes can pass by changing the inclination angle to form an elongated outlet (b). In this case, one guide plate is slightly longer than the other guide plate, so that it is guided in one direction, and once it flows into the container, it easily returns because the head of the bow hula is in the container. No longer.

[0007]

Since the mosquito extermination device of the present invention is constructed as described above, it is only necessary to put water in a container and place it in an invisible shade as much as possible and wait for spawning. In this case, the water is less than tap water. Well or rain water is better, and in the case of tap water, it is effective to dissolve a small amount of nuts such as Kutsuki,
The range of the mosquito's action is about 10 meters, and the mosquito that sucks blood instinctively seeks a shaded water pool in search of a spawning place, so it is possible to reliably lay eggs just by installing it without other water pools. The hatched larva, ie the bow hula, repeats up and down movements mainly as described above and becomes a pupa in about one week, during which it flows out into a container and becomes a mosquito and dies in a few days in search of an exit. It is said that eggs are laid several times, about 100 at a time. However, the present invention captures the larvae at the stage of larvae, so that when used over a wide range for a long period of time, its effect is fully demonstrated.
