BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an attractant for attracting and capturing cockroaches.

0002

[Prior Art and Problems to be Solved by the Invention] Cockroaches are pests with high reproductive capacity, and their complete capture is extremely difficult.

[0003] In order to capture cockroaches, it is first necessary to attract the cockroaches. It has long been known that pests such as cockroaches collectively attract members of the same species with their secretions, feces, or extracts. It has been proposed to capture cockroaches by utilizing these properties (for example, Japanese Patent Publication No. 18518/1983). However, in order to capture and exterminate cockroaches by such a method, a large number of cockroaches are required, and it is extremely difficult and impractical to collect a large amount of insect feces.

[0004] It has also been proposed to use chemical substances and natural substances as attractants. Specifically, methyl or ethyl esters of fatty acids such as myristic acid and palmitic acid (Japanese Patent Publication No. 44-320), saturated or unsaturated aliphatic alcohols (Japanese Patent Publication No. 44-11920), and non-reducible starch hydrolysis. (Japanese Unexamined Patent Publication No. 50-88235), carboxylic acid esters having a cyclohexyl group (Japanese Unexamined Patent Publication No. 50-88234), aromatic aliphatic ketones, alcohols, aldehydes, lactones, esters (
JP 50-49434, JP 50-53540)
, Aloe plant and extract (Japanese Patent Application Laid-Open No. 61-291505
Publication No.), eucalyptus leaf or its extracted components, carbon number 7
1 to 9 ketones (Japanese Patent Publication No. 114904/1982), vanillin, ethylvanillin, isovanillin, piperonal, piperonal acetone, 2,6-nonadienal, 2,6-nonadienol (Japanese Patent Publication No. 1136/1982)
Publication No. 7), Kakitsubata seed oil, Iris seed oil, Iris seed oil, Astragalus japonica seed oil (Unexamined Japanese Patent Publication No. 1983-
No. 135403), pine resin (Japanese Patent Application Laid-open No. 125-1983)
041), sesame oil (JP-A-53-91140), general formula (1)

[0005]

[Chemical formula 1]

Compounds represented by (wherein R1 represents a linear or branched alkyl group having 3 to 7 carbon atoms, R2 represents a hydrogen atom or a methyl group, and R represents a hydroxyl group or an amino group) ( A method of attracting cockroaches using Japanese Patent Application Laid-Open No. 63-96101) is disclosed.

[0007] However, these substances have problems such as weak attraction, difficulty in manufacturing, and high cost.
None of them were fully satisfactory in practical terms.

Furthermore, milk, cheese, krill flour, powdered feed, bran, wheat flour, rice flour or a mixture thereof (
JP-A No. 62-278930), the combination of gelatin, fish protein, animal protein such as casein, animal meat, animal meat extract, and other substances hydrolyzed with acids, alkalis, enzymes, etc., and glucose and fructose. Thermal reaction products (JP-A No. 57-95904), compositions obtained by acid decomposition of defatted lees of grains such as soybeans, corn, cottonseed, rapeseed, and sesame, and then concentrated and neutralized (JP-A No. 53-15424) Publication No.), fishmeal,
A method of attracting with food such as a mixture of wheat flour, soybean oil cake, rice bran, feed yeast, and sesame oil cake (Japanese Unexamined Patent Publication No. 13227/1982) has been proposed, but food is easily deteriorated and the effect is not sustainable. There was a problem.

[0009]Therefore, there has been a desire for a cockroach attractant that does not have such drawbacks, has an excellent cockroach attracting effect, and is easily available.

0010

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present inventors investigated the effects of many substances in order to find a cockroach attractant. As a result, the present inventors found that the extract of a plant of the genus Tribulatum of the family Tribulaceae is effective against cockroaches. The present invention was completed based on the discovery that it has an excellent attracting effect regardless of the type of insect, larva or adult, and regardless of gender.

[0011] That is, the present invention provides a cockroach attractant containing an extract of a plant of the genus Tribulata of the family Tribulaceae as an active ingredient.

[0012] The plant of the genus Tribulaceae used in the present invention is not particularly limited as long as it belongs to this genus. Specifically, examples include the Japanese sagebrush, the Bahamas sagebrush, and the like.

[0013] There are no particular restrictions on the preparation of extracts of plants of the genus Prunus genus used in the present invention, but for example, the trunks, branches, leaves, roots, etc. of the plants of the genus Prunus genus mentioned above may be squeezed, or extracted using water or an organic solvent. This will be implemented by Examples of organic solvents used here include hydrocarbons, halogenated hydrocarbons, ethers, acetals, ketones, esters, alcohols, polyhydric alcohols, fatty acids, and phenols, which may be used alone or in combination of two or more. It may also be used with water. In the case of extraction using water or an organic solvent, the amount used is not particularly limited, but it is usually preferably about 1 to 20 times the weight of the plant of the genus Prunus. Moreover, pressing and extraction can be performed by conventional methods.

The extract thus obtained may be used as it is as a cockroach attractant, but if necessary, it may be further subjected to steam distillation, carbonization, fractionation with various organic solvents,
It is also possible to use those purified and fractionated by distillation or the like. Such fractions and components include, for example, Yusoubok oil (G
uaiac wood oil), α-guayen,
Examples include δ-guaien, β-brunessen, guaiol, and the like, and these components can be used alone or in a mixture of two or more. The extract thus obtained may be used as it is as a cockroach attractant, but it may also be used after being concentrated or diluted if necessary.

[0015] The amount of the cockroach attractant of the present invention to be used is not particularly limited, but it is preferably used at a relatively low concentration of 10% (w/v) or less as an extract of a plant of the genus Prunus cucumber, since it exhibits an attracting effect in a small amount. . Furthermore, the cockroach attractant of the present invention may be used by adsorbing, mixing or dispersing the active ingredient, an extract of a plant of the genus Prunus genus, on a suitable carrier or food. May be used together.

[0016]

EFFECTS OF THE INVENTION The cockroach attractant of the present invention is hard to change in quality, has a strong attracting force, and has a long duration, so if it is used, a large number of cockroaches can be efficiently attracted and captured.

[0017]

[Examples] Example 1 Production of cockroach attractant: Guajacum officiali Li
Nnaeus) was collected, finely crushed, and then steam distilled to obtain sagebrush oil.

Test Example 1 In the center of a plastic vat measuring 80 cm long x 45 cm wide x 20 cm high, two pieces of filter paper measuring 1.5 x 3 cm were placed approximately 30 cm apart. ,
A 1% (w/v) methanol solution of fragrant oil obtained in Example 1 and a 1% (w/v) methanol solution of α-guayene, δ-guayene, β-brunessen, and guaiol obtained by fractionating fragrant oil. ) 100 mg was added dropwise, and the other filter paper 1 was used as a control filter paper to which no sample was added. Next, 30 adult male American cockroaches were released into the vat in a dark room under the lighting of a darkroom lamp, and the cockroaches were released for 15 minutes.
The total number of cockroaches that gathered on each filter paper per minute was counted. Furthermore, the following equation (1)

[0019]

[Math 1]

The values obtained by [0020] were evaluated according to the following criteria. These results are shown in Table 1. -: 0% +: Less than 15% ++: 15% or more and less than 30% +++: 30% or more

[0021]

[Table 1]

[0022] As shown in Table 1, the five components contained in the extract of a plant of the genus Prunus genus are as follows:
Cockroach attracting activity was observed. From this, it has become clear that the use of a plant extract of the genus Prunus as a cockroach attractant is an extremely effective means.

Example 2 The methanol, ethanol and hexane extracts of crushed Porphyra spp. were evaluated in the same manner as in Test Example 1. The results are shown in Table 2.

[0024]

[Table 2]

[0025] As shown in Table 2, the cockroach attracting activity was also observed in the crude extract extracted with an organic solvent after crushing the Prunus nigra plant. From this, it was confirmed that the crude extract of plants of the genus Prunus genus also has effectiveness as a cockroach attractant.
