Wasp is a type of bee, meaning a large bee. Like bees, wasps are pollinating insects, but the main net function in the ecosystem of wasps is pest control. Wasps act as predators of insects in forests and are particularly important in controlling the explosive growth of forest pests, such as certain moth larvae. However, in order to obtain nectar and prey, they often attack beehives and hunt and eat insects such as warts, warts, spiders and cicadas. In addition, wasps are known as dangerous insects because they sting, which is deadly toxic to humans.

Recently, the appearance of wasps has increased significantly due to abnormal temperatures caused by global warming, and deaths have occurred due to the attacks of wasps. In 2016 alone, 119 mobilizations to remove wasps were counted at about 128,000, accounting for more than 80% of the firefighting activities from August to October, and human damage caused by wasps is becoming a serious problem. Also, because wasps kill bees, they cause great economic damage to beekeepers.

Conventionally, in order to combat such wasps, they were killed by electric shock using electricity, captured with dragonflies, etc., or removed by flame of insecticides (Korean Patent Registration No. 10-1052214, Korean Patent Laid-Open Patent No. 10-2016-0089888 No. and Korean Patent No. 10-1810676). However, the conventional wasp repelling technology requires the development of a safe and rapid wasp repelling method that can effectively improve the inconvenience and risk that the user must wear safety protective equipment and evacuate the surrounding people.

Gosam is a perennial herb belonging to the dicotyledonous rosewood leguminous family. It is a wild flower that grows wild in the mountains of the country.

Hereinafter, the present invention will be described in more detail through examples. However, the following examples are for illustrating the present invention, and the scope of the present invention is not limited thereto.

<Example>

1. Preparation of Gosam extract

The roots of Korean ginseng were thoroughly washed with water and naturally dried for 6 days, followed by cutting and grinding. To 5 kg of the pulverized Gosam pulverized to 1 to 2 mm, 10 times the weight of 50% ethanol was added, followed by cooling extraction under reflux for 5 hours in a constant temperature water bath at 80°C, followed by filtration. It was concentrated under reduced pressure, lyophilized and stored at room temperature.

2. Fabrication of foam-generating spray to combat wasps

In order to prepare a foam-generating spray for combating wasps, the freeze-dried Gosam extract was diluted with purified water to contain 1% by weight of Gosam solid, and 0.5% by weight of liquid soap and 0.2% by weight of lauramine oxide (foam accelerator) were added.

After putting the composition in an aluminum container for spraying of 500 ml, butane gas as a hydrocarbon propellant and dimethyl ether as a non-hydrogen propellant were filled as shown in Table 1 below, and the container was sealed by attaching an injection pipe, a nozzle part, and a valve to create a foam spray. Was produced.

Butane (% by weight) 0 3 4 5 8 Dimethyl ether (% by weight) 8 5 4 3 0 Spray distance (meter) 7 5 1.5 0.5 0.1 Bubble stability observation Bubble burst immediately Stable without swelling or collapse Fine bubble expansion Slight bubble swell Remarkable bubble expansion

As shown in Table 1, as the content of butane increased, the foam was continuously expanded and stable, but it was confirmed that the spraying distance significantly decreased. On the contrary, it was confirmed that the higher the content of dimethyl ether, the easier the bubble collapsed, but the spraying distance improved. Therefore, an optimal foam-generating spray for wasp repelling was prepared under the conditions of 3% by weight of butane and 5% by weight of dimethyl ether with a stable foaming distance of 5 meters.

3. Evaluation of the practicality of foam-generating spray to combat wasps

Before applying the foam-generating spray to the honeycomb, it was sprayed using a honeycomb-like egg plate. As a result of spraying by pressing the valve with a constant force for about 1.3 seconds, it was confirmed that a rich foam having a laminate thickness of 30 to 35 mm was generated (see FIG. 1). In addition, it was confirmed that the foam was maintained in shape for about 1 to 2 minutes. Through this, not only when the wasp is gliding, but also when it is inside the beehive, it will be surrounded by bubbles while coming out of the beehive, so that the wasps can be effectively eradicated.

In order to confirm the practicality of the foam generating spray, a simulation test was conducted to place the model honeycomb at a distance of 2.2 m, and 5 wasps collected from a nearby mountain were carefully injected, and then the foam generating spray was sprayed for 1 to 2 seconds. (See Fig. 2). As a result, it was confirmed that the foam-generating spray reached a beehive located at a distance of 2.2 m in a straight line with an injection angle of 5 to 10 degrees in 0.8 seconds, causing 3 out of 5 wasps in the model beehive to fall. In addition, it was confirmed that the crashed wasp showed an insecticidal effect of Gosam extract, a natural insecticide component, as the foam dries, and is suppressed within 3 minutes.

Therefore, it was confirmed that it is a very excellent and safe method compared to conventional methods that require a safety protection device to be worn and a professional manpower and a long time spent in that it can safely, accurately and quickly suppress wasps even at a distance of 2 meters or more. .
