Description

{Attracting And Capturing Trap Of Forest Mosquitoes Using Ovipositional Characteristic Of Mosquitoes}

The present invention relates to a forest mosquito inducing and capturing trap utilizing the oviposition characteristics of mosquitoes, and more particularly, to a forest mosquito oviposition inducing and capturing trap capable of providing an oviposition site utilizing the oviposition characteristics of pregnant female forest mosquitoes living in forests or residential areas near forests, thereby inducing the oviposition of pregnant female forest mosquitoes, and capturing the female forest mosquitoes and eggs laid by the female forest mosquitoes.

There are 56 species in 9 genera recorded in Korea, and 14 species of mosquitoes are currently known to transmit infectious diseases in Korea or to transmit infectious diseases brought in from overseas. Transmission of infectious diseases by mosquitoes occurs when pregnant female mosquitoes suck blood to supplement necessary proteins through human or animal blood.

In addition, 18 species of Aedes mosquitoes known to inhabit our country are recorded, among which the representative ones include the golden forest mosquito (Aedes vexans nipponii), the Asian white-striped forest mosquito (aedes albopictus), and the red-striped forest mosquito (Ochlerotatus dorsalis).

The golden forest mosquito is the dominant species in Korea. The larvae are found in relatively clean water such as puddles, rice fields, irrigation ditches, ponds, and wetlands. Unlike other mosquito species, the adult female mosquito is active both day and night. It often attacks people in residential areas, gardens, and parks, and is known to transmit diseases such as West Nile virus.

In addition, the Asian white-lined mosquito is a diurnal mosquito that is mainly active during the day and sucks blood. It is often found in green spaces such as parks, grasslands, palaces, and parks in mountains and cities, and is a species that can transmit various types of viral infectious diseases, and is known to transmit dengue virus, Zika virus, and chikungunya virus.

Also, the Aedes mosquito is active day and night, but is most active in the evening, mostly sucking blood outdoors rather than indoors, and is known to transmit the West Nile virus, etc. Females lay eggs near water or in wet soil, and they remain partially dry for at least 5 days before hatching when the water returns, and it is known that eggs in a dry state can survive for more than a year.

Meanwhile, the Aedes aegypti mosquito has not yet been found in Korea, but it has been one of the most widespread mosquito species over the past 20-30 years. It is also called the yellow fever mosquito and can transmit various infectious diseases including dengue fever, chikungunya fever, Zika fever, and yellow fever virus. Due to the active human and material exchange around the world, the inflow of the Aedes aegypti mosquito into Korea cannot be assured.

These forest mosquitoes mainly live in forests and near residential areas near forests. Unlike house mosquitoes that can breed all year round in warm human living spaces even in the winter, the forest mosquitoes that live in Korea are known to die as adults when the weather gets cold and spend the winter as eggs, hatching around the end of March when spring comes and growing into larvae, and becoming active as adult mosquitoes around the end of April to early May.

In addition, although there are differences depending on the type of mosquito, most forest mosquitoes lay eggs in stagnant water in various small containers such as natural tree holes, artificial containers, and old tires. Forest mosquitoes are known to use their senses of smell, taste, and sight to select a place where larvae can live and lay eggs.

In addition, various control methods have been devised for mosquitoes, which are pests that transmit infectious diseases. For example, in the past, chemical control methods were mainly used to directly kill adult mosquitoes using chemicals such as pyrethroid, organophosphate, carbamate, and neonicotinoid. However, these methods have raised the same problems as soil contamination and destruction of the ecosystem.

Accordingly, various repellents are being developed that can prevent damage from adult mosquitoes without causing harm to the environment or the human body. For example, Korean Patent No. 10-2291985 (hereinafter referred to as “Patent Document 1”) discloses a “mosquito repellent composition that is safe for the human body,” and Korean Patent No. 10-2323497 (hereinafter referred to as “Patent Document 2”) discloses a “pest repellent composition” that can repel various types of mosquito and tick pests without causing harm to the environment or humans.

In addition, physical devices for capturing or repelling adult mosquitoes as physical control devices are being developed. For example, Korean Patent No. 10-1917108 (hereinafter referred to as “Patent Document 3”) discloses a “mosquito attracting trap,” Korean Patent No. 10-2396188 (hereinafter referred to as “Patent Document 4”) discloses a “pest capturing device,” and Korean Patent No. 10-2492204 (hereinafter referred to as “Patent Document 5”) discloses a “pest repelling lighting device.”

Meanwhile, as the importance of forests has been highlighted recently, forest management has been actively carried out in parks and rivers in urban areas, leading to a large increase in forests in or near urban areas. In addition, in line with the wellness culture of wanting to be with nature, residences or lodging facilities such as country houses, condos, and pensions in or near forests have been increasing significantly, and the number of people using natural recreation forests or campsites has also increased significantly.

That is, recently, as forests have increased significantly in or near spaces where people live or work, and as lifestyles or activities close to forests have increased significantly, the risk of transmission of infectious diseases transmitted by forest mosquitoes has increased.

Therefore, there is a need for control of forest mosquitoes that pose a risk of transmitting infectious diseases, but the repellents, repellent devices, and capture devices disclosed in the above-mentioned patent documents 1 to 5 have no effect or are very limited in open spaces such as forests, urban parks, or rivers.

In addition, in the past, pesticides were sprayed on forests or rivers near urban areas to control the disease. However, this method is not only problematic for the ecosystem, such as causing soil pollution, affecting non-target insects other than mosquitoes, and causing biomagnification, but it is also not a desirable method, as the target species, mosquitoes, are also part of the ecosystem.

Therefore, recently, as a control measure against forest mosquitoes, passive methods such as eliminating habitats and breeding grounds for forest mosquitoes, such as keeping grass short or removing it around houses, organizing old tires, artificial containers such as glass bottles or plastic containers, and flower pots around houses, or periodically replacing the water in them, etc., have been suggested and campaigned for.

Accordingly, the inventors of the present invention have come up with the idea that the population of forest mosquitoes living in forests near residential areas can be effectively controlled by implementing the above-mentioned passive methods while also actively providing breeding sites for forest mosquitoes and capturing mosquito eggs and adult mosquitoes laid in the provided breeding sites.

[Example 1]

The forest mosquito attracting and capturing trap according to Example 1 of the present invention will be described in detail below with reference to FIGS. 1 to 3.

FIG. 1 is a perspective view of a forest mosquito attracting and capturing trap according to Example 1 of the present invention, FIG. 2 is a drawing showing each component of a forest mosquito attracting and capturing trap according to Example 1 of the present invention, and FIG. 3 is a drawing for explaining the installation of a scattering net according to Example 1 of the present invention.

As illustrated in FIGS. 1 to 3, the forest mosquito attracting and capturing trap according to the present invention comprises a housing (100) having an internal space with an open front surface, a water tank receiving section (200) positioned in a lower space (101) of the internal space of the housing (100) and having a storage space with an open upper surface formed therein, a spawning tank section (300) stored in the storage space of the water tank receiving section (200) and having a water storage space with an open upper surface formed therein, attracting water (500) contained in the water storage space of the spawning tank section (300) and used to attract pregnant female forest mosquitoes, and a spawning support section (400) stored in the water storage space of the spawning tank section (300) and floating on the attracting water (500).

First, the housing (100) is configured in a shape with an open front and an internal space, as shown in (a) of Fig. 2.

That is, the internal space of the housing (100) is formed by a plate-shaped bottom portion, plate-shaped side wall portions (111, 112) extending vertically from both sides of the bottom portion, a plate-shaped rear wall portion (not shown) extending vertically from the rear of the bottom portion, and a plate-shaped roof portion (121, 122) that comes into contact with the upper ends of the side wall portions (111, 112) and the rear wall portion and covers the upper surface, and is formed so that the front surface is open.

In addition, the internal space of the housing (100) is formed as one space, but the internal space is divided into upper and lower parts, and the space located at the lower side is called the lower space part (101), and the space located at the upper side is called the upper space part (102).

In addition, the roof portion (121, 122) is preferably formed to form a slope that rises in the center and becomes lower toward both sides, since the housing (100) is installed so that it is exposed to the outdoors in a natural state such as a forest.

That is, by arranging the first roof part (121) and the second roof part (122) so that they are inclined relative to each other so that the center rises, it is possible to prevent rainwater when it rains or leaves falling from surrounding trees from accumulating on the roof parts (121, 122).

In addition, as shown in (a) of FIG. 1 and FIG. 2, a hanging part (130) capable of hanging the forest mosquito attracting and capturing trap of the present invention on a tree branch or the like may be further included in the raised center of the roof part (121, 122).

The above hanging member (130) is formed with a plurality of holes (131), and as shown in Fig. 8, the above forest mosquito attracting and capturing trap can be hung on a tree branch or the like located at the installation location using a string (800).

Next, the water tank storage section (200) is a box-shaped section having a storage space with an open upper surface, as shown in (b) of FIG. 1 and FIG. 2, and is located in the lower space section (101) of the internal space of the housing (100).

In addition, since the tank receiving portion (200) is located in the lower space portion (101) of the housing (100), it is preferable that the external shape of the tank receiving portion (200) be formed in a shape and size that matches the lower space portion (101) of the housing (100).

In addition, a handle (210) that can pull out or push in the water tank storage unit (200) may be provided on the front surface of the water tank storage unit (200).

Next, the spawning tank (300) is a box-shaped tank space formed with an open upper surface, as shown in (c) of FIG. 1 and FIG. 2, and is stored in the storage space of the tank storage unit (200).

Therefore, it is preferable that the external shape and size of the spawning tank (300) be formed in a shape and size that matches the storage space of the tank storage unit (200).

In the first embodiment of the present invention, the tank receiving portion (200) and the spawning tank portion (300) are configured separately, and the spawning tank portion (300) is inserted into the storage space of the tank receiving portion (200), but the tank receiving portion (200) and the spawning tank portion (300) may be provided as one unit.

In this case, as described later, since the spawning tank (300) contains a liquid such as a attractant, at least the tank space in the integrated tank receiving unit (200) and the spawning tank (300) must have a waterproof function.

Next, the scattering support member (400) includes a mesh portion (420) formed in a mesh structure and a plate-shaped border portion (410) surrounding the border of the mesh portion (420), as shown in (d) of FIG. 2.

That is, the above-mentioned scattering support member (400) includes a plate-shaped frame member (410) and a mesh member (420) formed in the center thereof with a mesh structure, and is located in the tank space of the tank receiving member (200).

In addition, the above-mentioned spawning support part (400) is a place where pregnant female forest mosquitoes lay eggs in the attractant water (500) while being supported by the mesh part (420). As shown in (a) of FIG. 3, the attractant water (500) is contained in the tank space of the spawning tank part (300), and as shown in (b) of FIG. 3, the above-mentioned spawning support part (400) is positioned in the water storage space of the spawning tank part (300).

At this time, the scattering support member (400) is provided to float on the attractant water (500), so that the scattering support member (400) also rises and falls as the attractant water (500) increases and decreases.

Therefore, in order for the scattering support (400) to float on the attracting water (500), the density of the scattering support (400) must be smaller than the density of the attracting water (500). In order for the scattering support (400) to rise and fall smoothly, it is preferable that the length of each side of the circumference of the scattering support (400) be smaller than the length of each side of the circumference of the water storage space of the scattering tank (300).

In this way, since the scattering support (400) is floating on the attractant (500), and rises and falls together with the increase and decrease of the attractant (500), the distance between the mesh part (420) of the scattering support (400) and the attractant (500) is always maintained almost constant.

At this time, it is preferable that the distance between the mesh part (420) of the spawning support part (400) and the attractant water (500) is about 2 to 5 mm. This is because it takes into account the fact that pregnant female forest mosquitoes check whether the water in the spawning site is suitable for spawning before laying eggs.

That is, a pregnant female forest mosquito located in the mesh part (420) of the spawning support part (400) for spawning can check at a close distance whether the attractant water (500) is suitable for spawning, and can spawn in the attractant water (500) while supported by the mesh part (420).

In addition, the distance between the mesh part (420) of the scattering support (400) and the attractant (500) can be secured by the step between the bottom surface of the mesh part (420) and the bottom surface of the frame part (410). At this time, considering the degree to which the scattering support (400) is immersed in the attractant (500), it is preferable to determine the thickness of the frame part (410) so that the distance between the mesh part (420) and the attractant (500) does not exceed 5 mm.

[Example 2]

The forest mosquito attracting and capturing trap according to Example 2 of the present invention will be described in detail below with reference to FIGS. 4 and 5.

FIG. 4 is a front view of a forest mosquito attracting and capturing trap according to Example 2 of the present invention, FIG. 5a is a front perspective view of an adult mosquito attracting part according to Example 2 of the present invention, FIG. 5b is a rear perspective view of an adult mosquito attracting part according to Example 2 of the present invention, and FIG. 5c is a partial enlarged view of an adult mosquito attracting part according to Example 2 of the present invention.

Embodiment 2 of the present invention differs from Embodiment 1 in that it further includes an adult mosquito inducing portion (600) located in the upper space portion (102) of the housing (100), as illustrated in FIG. 4.

In this way, the reason why the adult mosquito inducing unit (600) is further included in Example 2 of the present invention is to capture forest mosquitoes that have come to find a bait for laying eggs by blocking their retreat route after laying eggs.

The above adult mosquito induction unit (600) includes an induction unit main body that provides an induction path for inducing the forest mosquitoes into the internal space of the housing (100), and an induction unit main body support unit that positions and supports the induction unit main body within the upper space (102) of the housing (100).

The above-described induction body includes a front opening (610) formed as a frame that fits into the open front inner side of the upper space (102) of the housing (100), a rear opening (620) formed as a frame located inside the upper space (102) of the housing (100), and an induction pipe (630) that forms a passage extending from the front opening (610) to the rear opening (620), wherein the front opening (610) is large and the rear opening (620) is formed in a small tubular shape.

The above-mentioned front opening (610) is formed as a frame that fits into the opened front inner side of the upper space (102) of the housing (100), as shown in FIG. 5a, and it is preferable that each frame, except for the lower frame, be provided so as to be in close contact with the opened front inner side of the upper space (102) of the housing (100).

In addition, it is preferable that the front edge of the water tank receiving portion (200) located in the lower space (101) of the housing (100) be provided so as to be in close contact with the inner side of the front opening of the lower space (101), and it is preferable that the lower frame among the frames forming the front opening (610) be provided so as to be in close contact with the upper front edge of the water tank receiving portion (200).

By doing so, it is possible to prevent adult mosquitoes from entering or exiting the internal space of the housing (100) other than the induction path formed by the induction unit body.

Next, the rear opening (620) is formed as a frame located inside the upper space (102) of the housing (100), as shown in FIGS. 5b and 5c, and the frame forming the rear opening (620) is formed in a ring shape with a circular opening having a diameter of 10 to 25 mm.

In the embodiment of the present invention, the rear opening (620) is illustrated as a circle, but is not limited thereto, and if an opening area similar to that of the rear opening (620) described above is secured, there is no particular limitation on its shape. For example, it may be a polygon such as a square, pentagon, or hexagon, or various shapes such as an oval or a star.

In addition, the frame forming the rear opening (620) further includes an access barrier (670) formed of a plurality of bars along the perimeter of the frame.

As shown in FIGS. 5b and 5c, the above-described access barrier (670) comprises a plurality of bar-shaped bars formed by protruding from the perimeter of the frame or an adjacent portion of the perimeter along the perimeter of the frame.

The above-mentioned access barrier (670) is intended to prevent adult mosquitoes that have entered the internal space of the housing (100) along the guide path formed by the main body of the guide unit from going out again through the rear opening (620).

Therefore, among the plurality of bars forming the above-described access barrier (670), it is preferable that at least adjacent bars protrude in different directions.

Next, the induction pipe (630) is formed in a tubular shape by a wall that extends in a film shape from the entire frame forming the front end opening (610) to the entire frame forming the rear end opening (620) as shown in FIGS. 5a and 5b.

In addition, as shown in Fig. 5c, a plurality of air holes (631) are provided in the wall of the induction pipe (630) through which air from the internal space of the housing (100) and the external natural environment can circulate.

The above-mentioned plurality of air holes (631) are provided as holes penetrating the wall of the induction tube (630), and there are no special restrictions on their size and shape as long as only air can pass through them and adult mosquitoes cannot enter or exit.

Next, the induction unit body support member is configured to fix and support the induction unit body in position within the upper space (102) of the housing (100), and includes a plurality of horizontal frames (650) extending inward from each corner of the frame forming the shear opening (610) into the upper space (102) of the housing (100), a plurality of vertical frames (660) connecting horizontal frames (650) that are vertically adjacent to each other among the plurality of horizontal frames (650), and a plurality of inclined frames (640) connecting horizontal frames (650) that are inclined to each other among the plurality of horizontal frames (650).

At this time, it is preferable that the plurality of horizontal frames (650) are provided so as to be in close contact with each corner of the upper space (102) of the housing (100), the plurality of vertical frames (660) are provided so as to be in close contact with the side wall portions (111, 112) of the upper space (102), and the plurality of inclined frames (640) are provided so as to be in close contact with the roof portions (121, 122) of the upper space (102).

In the embodiment of the present invention, the induction unit body support member is described as being configured to include the plurality of horizontal frames (650), the plurality of vertical frames (660), and the plurality of inclined frames (640), but is not particularly limited as long as the induction unit body is positioned and supported within the upper space (102) of the housing (100).

[Experimental Example 1]

In order to investigate the oviposition environment of pregnant female forest mosquitoes, two oviposition tanks (A1, A2) containing only water were prepared as shown in (a) of Fig. 6, and two oviposition tanks (B1, B2) containing water were prepared with a black rubber plate (700) placed on the bottom of the oviposition tank (300) as shown in (b) of Fig. 6. At this time, commercially available ultra-pure water was used as the attractant water.

In addition, the forest mosquito attraction and capture traps (hereinafter referred to as “traps”) of the above-mentioned Example 1 were installed at four points (Pa, Pb, Pc, Pd) as shown in Fig. 8. The traps were installed on a mountain near Dujeong Industrial Complex 1-gil, Seobuk-gu, Cheonan-si, Chungcheongnam-do, and a 10-m interval was maintained between the traps.

In addition, two spawning tanks (A1, A2) containing only water were each installed in traps installed at points (Pa, Pb), and two spawning tanks (B1, B2) containing water and having a black rubber plate (700) laid on the floor were each installed in traps installed at points (Pc, Pd). Then, the number of eggs laid by forest mosquitoes in each spawning tank (A1, A2, B1, B2) was counted for one week from July 18 to 24, 2023, and the results are as shown in [Table 1] below.

Next, considering that the installation location (place) of the trap may affect the laying of forest mosquitoes, the eggs laid in each laying tank (A1, A2, B1, B2) were collected separately, and then two laying tanks (A1, A2) containing only water were installed at the installation locations, and two laying tanks (B1, B2) containing water and a black rubber plate (700) on the floor were installed at the installation locations intersecting each other.

That is, two spawning tanks (A1, A2) containing only water were each installed in traps installed at points (Pc, Pd), and two spawning tanks (B1, B2) containing water and having a black rubber plate (700) laid on the floor were each installed in traps installed at points (Pa, Pb). The number of eggs laid by forest mosquitoes in each spawning tank (A1, A2, B1, B2) was counted for one week from July 25 to 31, 2023, and the results are as shown in [Table 2] below.

[Table 1]

[Table 2]

As shown in [Table 1] and [Table 2] above, forest mosquito eggs were found in both two spawning tanks (A1, A2) containing only water and two spawning tanks (B1, B2) containing water and a black rubber plate (700) on the bottom. As shown in Fig. 9, the eggs of forest mosquitoes laid at this time were mainly attached to the walls of the spawning tanks (300).

Therefore, it was confirmed that when water is used as a attractant, it can provide a breeding site for forest mosquitoes that can compete with natural breeding sites for pregnant female mosquitoes.

In addition, as seen in [Table 1] and [Table 2] above, the number of forest mosquito eggs laid in each of the two spawning tanks (B1, B2) with black rubber plates (700) on the bottom and water was found to be greater than the number of forest mosquito eggs laid in each of the two spawning tanks (A1, A2) that only contained water for two weeks.

That is, as shown in [Table 1] above, the total number of forest mosquito eggs laid in two spawning tanks (A1, A2) containing only water for one week from July 18 to 24, 2023 was 269, and the total number of forest mosquito eggs laid in two spawning tanks (B1, B2) containing water and having a black rubber plate (700) on the bottom was 549.

In addition, as shown in [Table 2] above, the total number of forest mosquito eggs laid in two spawning tanks (A1, A2) containing only water for one week from July 25 to 31, 2023, when the installation locations were switched, was 226, and the total number of forest mosquito eggs laid in two spawning tanks (B1, B2) containing water and having a black rubber plate (700) on the bottom was 410.

That is, it was shown that the oviposition attraction effect on pregnant forest mosquitoes was more excellent when a black rubber plate (700) was placed on the bottom of the spawning tank (300) and water was added, as in (b) of FIG. 6, than when only water was added to the spawning tank (300) as in (a) of FIG. 6.

[Experimental Example 2]

In order to determine whether the presence of forest mosquito eggs has an oviposition attraction effect on pregnant female forest mosquitoes, four types of attractants were prepared, and a black rubber plate (700) was placed on the bottom of each oviposition tank (300), as shown in Fig. 7.

The above-mentioned attractants were prepared with one type of pure water and three types of water in which forest mosquito eggs were soaked and then removed. At this time, the three types of water in which forest mosquito eggs were soaked and then removed were used by putting 10, 20, and 50 forest mosquito eggs per 100㎖ of pure water, soaking them for three days, and then removing the eggs. The forest mosquito eggs used at this time were collected from the mountains around Dujeong Industrial Complex 1-gil, Seobuk-gu, Cheonan-si, Chungcheongnam-do. This was done in consideration of the high possibility that adult mosquitoes attracted to the attractant water by the forest mosquito eggs used in the attractant water are of the same species.

In addition, the spawning tanks containing pure water were classified as T1, and the spawning tanks containing water with 10, 20, and 50 forest mosquito eggs per 100 ml of pure water were soaked for 3 days. The spawning tanks containing the water from which the eggs were removed were classified as T2, T3, and T4, respectively.

In addition, the four traps installed at the four locations (Pa, Pb, Pc, Pd) in [Experimental Example 1] were used as is, and each trap was equipped with spawning tanks T1, T2, T3, and T4 containing each attractant to capture eggs laid by pregnant female forest mosquitoes.

The capture period was 4 weeks from August 8, 2023 to September 4, 2023, and the spawning tanks T1, T2, T3, and T4 containing each attractant were rotated at 4 points (Pa, Pb, Pc, Pd) at one-week intervals to change the installation location.

When the location of each spawning tank (T1, T2, T3, T4) was changed every week, a new spawning tank containing the same number of attractants was used, and the previously used spawning tanks were recovered and the captured forest mosquito eggs were counted. The results are as shown in [Table 3] below.

[Table 3]

As shown in [Table 3] above, from August 8, 2023 to September 4, 2023, for four weeks, a total of 372 Forest mosquito eggs were captured in the spawning tank (T1) containing pure water, a total of 758 Forest mosquito eggs were captured in the spawning tank (T2) containing water in which 10 Forest mosquito eggs per 100㎖ of pure water were soaked for 3 days, a total of 972 Forest mosquito eggs were captured in the spawning tank (T3) containing water in which 20 Forest mosquito eggs per 100㎖ of pure water were soaked for 3 days, and a total of 1,075 Forest mosquito eggs were captured in the spawning tank (T4) containing water in which 50 Forest mosquito eggs per 100㎖ of pure water were soaked for 3 days.

That is, it was confirmed that water soaked with forest mosquito eggs was more effective as an attractant for pregnant female forest mosquitoes, and the greater the number of eggs soaked, the more effective the attractant effect.
