Description

[Technical field]

[0001] The present invention relates to a method for preventing flying pests from approaching a building using a combustion type flying pest access deterrent agent, and more particularly to a method for preventing flying pests such as horseflies, black flies, and bees from approaching a building using a combustion type flying pest access deterrent agent. [Background technology]

[0002] Flying pests such as bees, horseflies, and blackflies that live outdoors are problematic because they cause damage by biting in areas around houses such as gardens, entrances, and under eaves. There are approximately 3,000 known species of bees in Japan, of which approximately 20 species are said to have strong stinging powers. In recent years, with the development of housing estates in hilly areas around cities, human damage caused by bees with strong stinging powers has increased, and as a result, many bee control products such as aerosols have been sold on the market.

[0003] Conventionally, various studies have been carried out on the extermination of bees. In particular, the use of a drug with a fast effect is required, and for example, a bee behavior stopping agent containing 4-methoxymethyl-2,3,5,6-tetrafluorobenzyl 3-(2-cyano-1-propenyl)-2,2-dimethylcyclopropanecarboxylate as an active ingredient has been proposed (Patent Document 1). In addition, compositions containing metofluthrin and tetramethrin as active ingredients have been disclosed as bee control compositions with a fast effect, but both are intended to be fast-acting (Patent Document 2). Although such products that are primarily intended for extermination may appear to be easy to use for general users because they actively kill bees, they also entail the risk of counterattack from bees, and therefore are not necessarily good methods for the general public to carry out. Furthermore, if there are bees that have not been sufficiently exterminated, they may nest in buildings such as houses, which may lead to secondary damage.

[0004] Therefore, it was thought that ordinary people would prefer a method of creating a space where bees would not come near, rather than actively exterminating bees. In this situation, the applicant has disclosed a spiral-shaped incense coil containing an active ingredient with a specific combustion base and a specific vapor pressure as a mosquito coil suitable for outdoor use (Reference 3). This mosquito coil is disclosed as a product for use in large spaces or outdoors, and is basically highly effective against pests such as mosquitoes. However, it was thought that more in-depth study was needed on how to use it effectively against larger pests such as wasps. [Prior art documents] [Patent documents]

[0024] [Method of preventing flying pests from approaching buildings] The method for preventing flying pests from approaching a building of the present invention involves burning a combustion-type flying pest access-preventing agent containing (a) a pyrethroid compound and (b) a combustion base material, such as the combustion-type flying pest access-preventing agent of the present invention, at a location away from the building. In addition, the building in the present invention includes a house, an apartment, a public toilet, a garage, a warehouse, a prefabricated shed, a vinyl greenhouse, etc. By using the method for preventing flying pests from approaching a building of the present invention, flying pests such as bees, horseflies, and blackflies can be prevented from approaching a building such as a house, so that the user can work or be active in the yard, at the entrance, under the eaves, etc. with peace of mind, and further, by repeatedly using the method, secondary damage caused by bees nesting in buildings such as houses can be prevented.

[0025] In the method for preventing flying pests from approaching a building of the present invention, the position away from the building is preferably a position within 10 m from the exterior wall, and more preferably a position within 5 m from the exterior wall. By burning at a position within 10 m from the exterior wall of the building, flying pests such as bees, horseflies, and blackflies can be more effectively prevented from approaching a building such as a house. In addition, the position away from the building is preferably a position slightly separated from the exterior wall or a position 0.1 m or more away from the exterior wall, more preferably a position 0.1 m or more away from the exterior wall, and even more preferably a position 0.5 m or more away.

[0026] The burning time in the method for preventing flying pests from approaching a building of the present invention can be adjusted depending on the form of the combustion type flying pest access-preventing agent, and the burning time can be set to about 1 to 60 minutes in the form of a small lump of incense such as a cone, and the burning time can be set to 1 to 14 hours in the form of a spiral incense. Since the method for preventing flying pests from approaching a building of the present invention uses the combustion type flying pest access-preventing agent by burning it during the day, the burning time is preferably within 14 hours, more preferably within 1 minute to 14 hours, even more preferably 3 to 12 hours, and particularly preferably 6 to 10 hours.

[0027] Effective target pests for the combustion type flying pest approach prevention method of the present invention include bees such as honeybees, carpenter bees, two-horned paper wasps, black paper wasps, paper wasps, small hornets, Japanese hornets, small hornets, giant hornets, Japanese yellow hornets, and brown hornets; flies such as the white banded fly, Japanese toad flies, cow flies, red cow flies, golden flies, two-spotted syrup flies, foot-and-foot syrup flies, and giant syrup flies; Examples of pests include black flies such as blackfly and blackfly, mosquitoes such as Culex pipiens quinquefasciatus, Culex tritaeniorhynchus, Aedes albopictus, and Culex pipiens molestus, mosquitoes such as Aedes albopictus and Aedes aegypti, midges, moths, planthoppers, leafhoppers, midges, and moths, and are suitable for use on bees, horseflies, black flies, moths, planthoppers, leafhoppers, midges, midges, and moths. Among them, it is more suitable for use on bees, horseflies, and black flies that approach buildings and may cause bite damage or nesting damage, and is particularly suitable for use on bees. EXAMPLES

[0028] The present invention will be specifically described below by way of examples, but the present invention is not limited to these examples in any way.

[0029] Example 1 (a) 0.2 parts of transfluthrin and 0.04 parts of BHT were uniformly mixed with (b) 99.76 parts of combustion base material (wood flour, pyrethrum meal powder, tabu powder, starch), and then water containing a preservative was added and kneaded. The mixture was extruded and punched into a spiral shape, cut to a certain length, and dried in air to produce the combustion type flying pest access deterrent (spiral type) of Example 1.

[0030] Example 2 (a) 0.1 parts of Metofluthrin and 0.02 parts of BHT were uniformly mixed with (b) 99.88 parts of the combustion base material (wood flour, pyrethrum meal powder, tabu powder, starch), and then water containing a preservative was added and kneaded. The mixture was molded into a spiral shape using an extruder and a punching machine, cut to a certain length, and dried in air to produce the combustion-type flying pest access deterrent (spiral type) of Example 2.

[0031] Example 3 0.3 parts of (a) dl·d-T80-allethrin was uniformly mixed with 99.70 parts of (b) combustion base material (wood flour, pyrethrum meal powder, tabu powder, starch), and then water containing a preservative was added and kneaded. The mixture was extruded and punched into a spiral shape, cut to a certain length, and dried in air to produce the combustion type flying pest access deterrent (spiral type) of Example 3.

[0032] <Test 1: Preventing flying pests from approaching buildings> (Test Example 1) The combustion type flying pest access deterrent of Example 1 was burned for 3 hours at a position 3 m away from the lateral outer wall of a vinyl house (2.5 m high, 5 m wide, 2 m deep) covered with plants, and the state was filmed with a video camera, and the number of times (X) that Polistes chinensis touched the attractant plant during the 3 hours of burning was confirmed. The same observation was conducted for 3 hours under the condition that the combustion type flying pest access deterrent was not burned, and the number of times (Y) that Polistes chinensis touched the attractant plant was confirmed. The approach deterrent rate was calculated using the following formula (I), and the approach deterrent rate was 93%. [Access prevention rate (%)]=(YX) / Y×100...(I)

[0033] (Test Example 2) In Test Example 1, the combustion type flying pest access deterrent of Example 2 was used instead of the combustion type flying pest access deterrent of Example 1, and the rest of the test was conducted in the same manner as Test Example 1.The access deterrent rate was calculated and was found to be 91%.

[0034] (Test Example 3) In Test Example 1, the combustion type flying pest access deterrent of Example 3 was used instead of the combustion type flying pest access deterrent of Example 1, and the rest of the test was conducted in the same manner as Test Example 1, and the access deterrent rate was calculated to be 86%.

[0035] (Test Example 4) In test example 1, the combustible flying pest access deterrent of Example 1 was burned for 3 hours at a position 6 m away from the exterior wall, and the rest of the test was conducted in the same manner as in test example 1.The access deterrent rate was calculated and was found to be 72%.

[0036] (Test Example 5) In test example 1, the combustible flying pest access deterrent agent of Example 1 was burned for 3 hours at a position 12 m away from the exterior wall, and the rest of the test was conducted in the same manner as in test example 1, and the access deterrent rate was calculated, which was 14%.

[0037] From the results of Test Examples 1 to 4, Test Examples 1 to 4 in which the combustion type flying pest access blocking agent was burned at a position 0.5 to 10 m away from the outer wall of the vinyl greenhouse, which is a building, all showed a high access blocking rate of 70% or more against Polistes chinensis. Among them, Test Examples 1 to 3 in which the combustion type flying pest access blocking agent was burned at a position 0.5 to 5 m away all showed a high access blocking rate of 80% or more against Polistes chinensis, and were found to be excellent methods for blocking flying pests from approaching buildings. In addition, Test Example 5 in which the combustion type flying pest access blocking agent was burned at a position more than 10 m away from the outer wall of the vinyl greenhouse, which is a building, showed a slight access blocking effect of Polistes chinensis to the building. From this, it was found that burning the combustion type flying pest access blocking agent at a position 0.5 to 10 m away from the outer wall of the building, particularly burning at a position 0.5 to 5 m away from the outer wall of the building, is important in improving the flying pest access blocking effect on the building in the present invention.

[0038] <Test 2: Preventing flying pests from approaching buildings> On a sunny day in September, the combustible flying insect deterrent of Example 1 was burned for 7 hours (from 9:00 a.m. to 4:00 p.m.) at a position 3 m away from the outer wall of the entrance of a wooden house. During that time, the person was working at the entrance, but was not bitten by Culex pipiens, Asian tiger mosquitoes, horseflies, blackflies, etc. Furthermore, no midges, moths, bees, etc. were seen approaching the entrance.
