Detailed Description
The present invention will be described below, but the present invention is not limited to the following embodiments and can be implemented in any modification.
The flying pest attractant of the present invention contains an aliphatic alcohol (A) having 2 to 6 carbon atoms and/or an aliphatic acid ester (E) having 3 to 8 carbon atoms, and a specific carboxylic acid (H) which is a keto acid or a hydroxy acid having 3 to 5 carbon atoms, or acetic acid.
The flying pest attractant of the present invention contains a specific carboxylic acid (H) as an essential component. The specific carboxylic acid (H) is a keto acid or hydroxy acid having 3 to 5 carbon atoms, or acetic acid.
Several carboxylic acids are known to have an action of attracting pests and the like, but depending on the number of carbon atoms or the kind of substituents and the kind of pests, pests and the like may be repelled.
When the specific carboxylic acid (H) is a keto acid (carboxylic acid having a keto group), the number of carbon atoms may be 3, 4, or 5.
The keto group of the keto acid may be located at the α -position, the β -position or the γ -position.
The carbon chain of the keto acid may or may not have a branch. The keto acid may have an unsaturated bond between carbon atoms or may not have an unsaturated bond between carbon atoms.
Specific examples of such a keto acid having 3 to 5 carbon atoms include 2-oxopropanoic acid, 2-oxobutanoic acid, 3-oxobutanoic acid, 2-oxopentanoic acid, 3-oxopentanoic acid, 4-oxopentanoic acid, and 2-oxo-3-methylbutyric acid, and 1 or more of these keto acids may be used alone or 2 or more of them may be used in combination.
When the specific carboxylic acid (H) is a hydroxy acid (carboxylic acid having a hydroxyl group), the number of carbon atoms may be 3, 4, or 5.
The hydroxyl group of the hydroxy acid may be located at the α -position, the β -position, the γ -position, or the δ -position.
The carbon chain of the hydroxy acid may or may not have a branch. The hydroxy acid may have an unsaturated bond between carbon atoms or may not have an unsaturated bond between carbon atoms.
Specific examples of such hydroxy acids having 3 to 5 carbon atoms include 2-hydroxypropionic acid, 3-hydroxypropionic acid, 2-hydroxybutyric acid, 3-hydroxybutyric acid, 4-hydroxybutyric acid, 2-hydroxy-2-methylpropionic acid, 3-hydroxy-2-methylpropionic acid, 2-hydroxypentanoic acid, 3-hydroxypentanoic acid, 4-hydroxypentanoic acid, 2-hydroxy-2-methylbutyric acid, 3-hydroxy-2-methylbutyric acid, 2-hydroxy-3-methylbutyric acid, 3-hydroxy-2, 2-dimethylpropionic acid, and the like, and these hydroxy acids may be used alone in 1 kind or in a mixture of 2 or more kinds.
Particularly preferred attractant ingredients vary from pest to pest. Even the same compound may be highly palatable (easily attracted) at a certain concentration, and may be averted when the concentration is increased. Therefore, when two or more compounds are used in combination as the specific carboxylic acid (H), the concentration can be easily adjusted to a high concentration, and the effect on various pests can be easily exerted.
The flying pest attractant of the present invention contains at least either one of an aliphatic alcohol (a) having 2 to 6 carbon atoms and an aliphatic acid ester (E) having 3 to 8 carbon atoms as an essential component.
Among the aliphatic alcohol (a) and the aliphatic acid ester (E), there are known components as perfume components and components used as attractants for pests and the like. However, these components have an increased effect of repelling pests and the like due to the number of carbon atoms and the like.
In the flying insect pest attractant of the present invention, the specific carboxylic acid (H) is used in combination with the aliphatic alcohol (a) or the aliphatic acid ester (E) to synergistically enhance the insect pest attracting effect.
In particular, the case where 3 components of the aliphatic alcohol (a), the aliphatic acid ester (E), and the specific carboxylic acid (H) are contained is particularly preferable because the synergistic attraction effect is extremely strong.

Particularly preferred attractant ingredients vary from pest to pest. Even the same compound may be highly palatable (easily attracted) at a certain concentration, and may be averted when the concentration is increased. Therefore, when two or more compounds are used in combination as the aliphatic alcohol (a), the concentration can be easily adjusted to a high preference concentration, and the effect on various pests can be easily exerted.
In the present invention, the "aliphatic acid ester (E)" refers to an ester having a structure obtained by dehydration condensation of an aliphatic acid (E1) and an alcohol (E2), but is not limited to an ester produced by dehydration condensation of an aliphatic acid (E1) and an alcohol (E2).

Therefore, when two or more compounds are used in combination as the fatty acid ester (E), the concentration can be easily adjusted to a high preference concentration, and the effect on various pests can be easily exerted.
The flying pest attractant of the present invention contains, as active ingredients, both "an aliphatic alcohol (a) having 2 to 6 carbon atoms and/or an aliphatic acid ester (E) having 3 to 8 carbon atoms" and "a specific carboxylic acid (H) (which is a keto acid or a hydroxy acid having 3 to 5 carbon atoms, or acetic acid)" wherein the content ratio (on a mass basis) of the aliphatic alcohol (a), the aliphatic acid ester (E), and the specific carboxylic acid (H) is preferably 0.1 ≦ (H)/[ (a) + (E) + (H) ] ≦ 0.9, more preferably 0.2 ≦ (H)/[ (a) + (E) + (H) ] ≦ 0.8, and particularly preferably 0.3 ≦ (H)/[ (a) + (E) + (H) ] ≦ 0.7.
When the content ratio is within the above range, a sufficient attracting effect to various pests is easily exerted.
The content ratio of the fatty alcohol (a), the fatty acid ester (E), and the specific carboxylic acid (H) as the active ingredients in the flying pest attractant of the present invention is preferably 0.1 mass% to 20 mass%, more preferably 0.5 mass% to 10 mass%, and particularly preferably 1 mass% to 5 mass%, based on the sum of (a), (E), and (H) in the whole flying pest attractant.
When the content ratio is not less than the lower limit, a sufficient attracting effect can be exhibited. When the content ratio is not more than the upper limit, a suitable volatilization speed can be achieved, and the duration of the effect becomes sufficiently long.
As described above, the flying pest attractant of the present invention has a very strong synergistic attraction effect when it contains 3 components of the aliphatic alcohol (a), the aliphatic acid ester (E), and the specific carboxylic acid (H), and in this case, the content ratio (on a mass basis) of the aliphatic alcohol (a) to the aliphatic acid ester (E) is preferably 0.05 ≦ (a)/[ (a) + (E) ] ≦ 0.95, more preferably 0.10 ≦ (a)/[ (a) + (E) ] ≦ 0.90, and particularly preferably 0.20 ≦ (a)/[ (a) + (E) ] ≦ 0.80.
The flying pest attractant of the present invention may contain a solvent in addition to the aliphatic alcohol (a), the aliphatic acid ester (E), and the specific carboxylic acid (H) as the active ingredients, within a range not interfering with the effects of the present invention; other attractant components such as perfume and essential oil; a pesticidal component for killing the attracted pests; additives such as emulsifiers, dispersants, retention agents, preservatives and the like; and so on.
As the solvent, water may be mentioned; monohydric alcohols such as methanol, ethanol, propanol, isopropanol, and butanol; polyhydric alcohols such as ethylene glycol and propylene glycol; ketones such as acetone and methyl ethyl ketone; ethers such as tetrahydrofuran, dioxane, and diethyl ether; aliphatic hydrocarbons such as hexane, kerosene, and paraffin; aromatic hydrocarbons such as benzene and toluene; halogenated hydrocarbons such as chloroform and dichloroethane; esters such as ethyl acetate and butyl acetate; and the like, and these may be used alone in 1 kind, or may be used in combination in 2 or more kinds.
The flying pest attractant of the present invention can be used in general households and the like, and is preferably water, monohydric alcohol, polyhydric alcohol, or a combination thereof because safety to solvents is required. Water, ethanol, propylene glycol or a combination thereof is particularly preferred.
The optimum concentration of the active ingredient (the specific carboxylic acid (H), the aliphatic alcohol (a), and the aliphatic acid ester (E)) may vary depending on the type of the insect pest, and the flying insect pest attractant of the present invention can exert an attracting effect on various insect pests by appropriately diluting it with the solvent.
The form of the flying pest attractant of the present invention is not particularly limited, and the flying pest attractant may be used in the form of, for example, a liquid, a gel, a granule, a powder, or the like, or may be used by being sprayed.
The invention also relates to a method for repelling flying pests, which is characterized by using the flying pest attractant.
The method of repelling is not particularly limited, and an insecticidal component may be added to the flying insect attractant to kill the attracted insects by the action of the insecticidal component, or the attracted insects may be caught and repelled by a trap using an adhesive or the like, as shown in examples described later.
Pests tend to favor foods such as honey, saccharides, fruits, fruit-processed products, dairy products, fish-shellfish-processed products, fish-shellfish extracts, meat-processed products, meat extracts, liquors, lees, and grains, and therefore the attracting effect can be improved by using these foods in combination.
The above foods can be used alone 1 kind, or mixed 2 or more kinds.
It is particularly preferable that the flying pest attractant contain honey that most pests prefer.
The food component may be contained in the flying pest attractant of the present invention, or may be separately provided in the vicinity of a place where the flying pest attractant of the present invention is applied or provided.
The flying pest attractant of the present invention exerts an attracting effect particularly on flying pests such as flies, mosquitoes and flies, and is therefore preferably used for these pests.
Particularly, the fly bait is preferably used for flies such as houseflies, toilet flies and the like; mosquitoes such as culex pipiens pallens, aedes albopictus and the like; fruit flies, flea flies, agromyzidae, muscid mosquitoes, mothflies and other small flies.

That is, when the test chamber is viewed from above, the pieces (traps) provided with the attractant into which the test substance a (or the test substance H) permeates are disposed at the upper left (position <1>) and the lower right (position <4>), and the pieces (traps) provided with the attractant into which the test substances a + H permeate are disposed at the upper right (position <2>) and the lower left (position <3 >).
Approximately 100 drosophila melanogaster flies were housed in the test chamber. The number of flies (number of insects caught) caught by the adhesive sheet was investigated after about 24 hours after stocking.
In order to eliminate the influence of the difference in pest collection easiness due to the difference in position in the test chamber (the detailed reason is not clear, and it is considered that the influence is caused by the light irradiation method or the like), the same test was performed by reversing the positional relationship between the sheet (trap) provided with the attractant impregnated with the test substance a (or the test substance H) and the sheet (trap) provided with the attractant impregnated with the test substances a + H, and the number of flies trapped in the adhesive sheet was examined.
In the test performed with the positional relationship of the pieces (traps) being 2, the number of insects caught at the position where each piece (trap) was installed was accumulated, and the enhancement rate was calculated as the number of insects caught when the test substance a + H was used divided by the number of insects caught when the test substance a was used.
The test results in the case of using the combination of test substances of No.61 of Table 4 are shown in tables 5 and 6.
[ Table 5]
The reinforcing rate is 73/51-1.43
[ Table 6]
The reinforcing rate is 80/61-1.31
As can be seen from tables 5 and 6, in the case where ethanol was mixed with 3-hydroxybutyric acid, a synergistic attracting effect was exhibited on fruit flies as compared with the case where ethanol or 3-hydroxybutyric acid was used alone.
Table 7 shows the test results when the combinations of the other test substances shown in table 4 were used.
[ Table 7]
From table 7, it was confirmed that the mixture of the aliphatic alcohol (a) and the specific carboxylic acid (H) had a synergistic attracting effect on fruit flies as compared with the case of using the aliphatic alcohol (a) or the specific carboxylic acid (H) alone.
In addition, it was also confirmed that the aliphatic acid ester (E) and the specific carboxylic acid (H) have a synergistic attraction effect when a mixture of these is used, as compared with the case where they are used alone.
Further, it is found that when 3 combinations of the aliphatic alcohol (a), the aliphatic acid ester (E) and the specific carboxylic acid (H) are mixed, the reinforcing ratio is very high, and the synergistic attraction effect tends to be further enhanced.
Next, a fruit fly attraction test was performed by using a mixture of two or more compounds as at least one of the "test substance a or the test substance E" and the test substance H.
Table 9 shows the test results in the case of using the combinations of the test substances shown in table 8.
[ Table 8]
[ Table 9]
From table 9, it was also confirmed that when a mixture of two or more compounds was used as the test substance a or the test substance E, a synergistic attracting effect was exhibited on the fruit flies when the aliphatic alcohol group having 2 to 6 carbon atoms or less and the aliphatic acid ester group having 3 to 8 carbon atoms or less were mixed, as compared with the case where the aliphatic alcohol group or the aliphatic acid ester group was used alone.
From table 9, it was also confirmed that a synergistic attracting effect was exhibited on fruit flies in the case of using a mixture of two or more compounds as the test substance a, the test substance E, and the test substance H, as compared with the case of using the aliphatic alcohol (a) or the specific carboxylic acid (H) alone.
The same tendency was observed for the aliphatic acid ester (E) and the specific carboxylic acid (H).
Furthermore, when 3 combinations of the aliphatic alcohol (a), the aliphatic acid ester (E), and the specific carboxylic acid (H) are mixed, the enhancement rate is very high in the same manner, and the synergistic attraction effect is further improved.
Test example 2 (attracting test for mothflies)
Using 582mm (length) x 900mm (width) x 600mm (height) (0.31 m)3) The same test as in test example 1 was carried out using mothflies as test insects for the plywood container of (1).
The results of the tests in the case where one compound was used as each of the test substance a, the test substance E, and the test substance H (the case where the combination of the test substances shown in table 10 was used) are shown in table 11.
[ Table 10]
[ Table 11]
From table 11, it was confirmed that, in the case of mothflies as well as in the case of fruit flies, the fatty alcohol (a) and/or the fatty acid ester (E) has a synergistic attracting effect when used in combination with the specific carboxylic acid (H). When 3 combinations of the aliphatic alcohol (a), the aliphatic acid ester (E), and the specific carboxylic acid (H) are mixed, the reinforcement ratio is very high.
Next, a mothfly attraction test is performed by using a mixture of two or more compounds as at least one of the "test substance a or the test substance E" and the test substance H.
Table 13 shows the test results in the case of using the combinations of the test substances shown in table 12.
[ Table 12]
[ Table 13]
From table 13, even when a mixture of two or more compounds is used as the test substance a, the test substance E, and the test substance H, the same tendency is exhibited as in the case where a single substance is used as the test substance.
Test example 3 (attraction test for culex pipiens pallens)
The test substance a (aliphatic alcohol (a)), the test substance E (aliphatic acid ester (E)), the test substance H (specific carboxylic acid (H)), the test substance a + H (mixture of aliphatic alcohol (a) and specific carboxylic acid (H)), the test substance E + H (mixture of aliphatic acid ester (E) and specific carboxylic acid (H)), and the test substance a + E + H (mixture of aliphatic alcohol (a), aliphatic acid ester (E), and specific carboxylic acid (H)) shown in table 14 were mixed with sugarcane black honey at 2.0% respectively to prepare liquid attractants.
The prepared liquid attractant was charged in 10.0g each in a circular container of 60mm (inner diameter) × 45mm (height).
[ Table 14]
Using 850mm (length) × 1500mm (width) × 820mm (height) (1.04 m)3) The plywood container of (1) was used as a test chamber. The 2 sides of the container were covered with wire mesh and a transparent plastic plate was placed on top for easy viewing.
4 adhesive sheets (4 holes of 5mm in diameter) of 100mm × 80mm were prepared, and 2 of these were set on a circular container to which a liquid attractant with test substance A (or test substance H) was added, to prepare a trap. The other 2 were placed on a circular container to which a liquid attractant with test substance a + H was added to make a trap.
4 traps were placed across the test chamber at 300mm intervals. That is, when the test chamber is viewed from above, traps using a liquid attractant with test substance a (or test substance H) are provided at the upper left (position <1>) and lower right (position <4>), and traps using a liquid attractant with test substances a + H are provided at the upper right (position <2>) and lower left (position <3 >).
Approximately 100 culex pipiens pallens were housed in the test chamber. The number of culex pipiens pallens captured by the adhesive sheet was investigated after about 24 hours after stocking.
In addition, the same test was performed by reversing the positional relationship between the trap using the liquid attractant with the test substance a (or the test substance H) and the trap using the liquid attractant with the test substances a + H, and the number of culex pipiens pallens trapped by the adhesive sheet was examined.
The test results in the case of using the combination of test substances of No.81 of table 14 are shown in tables 15 and 16.
[ Table 15]
The reinforcing rate is 83/64-1.30
[ Table 16]
The reinforcing rate is 85/62-1.37
From tables 15 and 16, it was confirmed that 1-butanol and 2-oxopropanoic acid were mixed together to provide a synergistic attraction effect against Culex pipiens pallens, as compared to the case of using 1-butanol or 2-oxopropanoic acid alone.
Table 17 shows the test results when the combinations of the other test substances shown in table 14 were used.
[ Table 17]
From table 17, it was confirmed that the synergistic attraction effect was exhibited when the aliphatic alcohol (a) and/or the aliphatic acid ester (E) was used in combination with the specific carboxylic acid (H) in the same manner as in the case of fruit flies in the case of culex pipiens pallens. When 3 combinations of the aliphatic alcohol (a), the aliphatic acid ester (E), and the specific carboxylic acid (H) are mixed, the reinforcement ratio is very high.
Next, a mothfly attraction test is performed by using a mixture of two or more compounds as at least one of the "test substance a or the test substance E" and the test substance H.
Table 19 shows the test results in the case of using the combinations of the test substances shown in table 18.
[ Table 18]
[ Table 19]
From table 19, even when a mixture of two or more compounds is used as the test substance a, the test substance E, and the test substance H, the same tendency is exhibited as in the case where a single substance is used as the test substance.
