Description

[Technical Field]

[0001] This patent application claims priority under the Paris Convention to and the benefit of Japanese Patent Application No. 2020-217328 (filed December 25, 2020), the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to a method for controlling harmful annelids using natural pyrethrins. [Background technology]

[0003] Various compounds have been investigated to date for the purpose of controlling harmful annelids. For example, Patent Document 1 describes deet and synthetic pyrethroids, particularly metofluthrin and transfluthrin, as repellent components for leeches. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-202629 Summary of the Invention [Problem to be solved by the invention]

[0005] However, while the conventional control methods mentioned above can repel harmful annelids approaching the human body, they are not suitable for eliminating harmful annelids from their habitats. Furthermore, even if they are repelled once, they are not killed, so their density in their habitat does not decrease, and once the repellent effect wears off, they will return to the human body or the area to be controlled.

[0006] Therefore, an object of the present invention is to provide a method for quickly exterminating harmful annelids from their habitats.

[0007] An object of the present invention is to provide a method for exterminating harmful annelids. [Means for solving the problem]

[0008] The present invention is as follows. [1] A method for exterminating harmful annelids, comprising applying an effective amount of natural pyrethrin to the harmful annelids, or to a place where the harmful annelids live or where they are expected to appear. [2] The method of [1], wherein the harmful annelid is a member of the class Hirudinida and order Arhynchobdellida. [3] The use of natural pyrethrins to control harmful annelids. [4] The harmful annelids are of the class Hirudinida and order Arhynchobdellida. [3] [Effects of the Invention]

[0009] According to the present invention, harmful annelids can be rapidly and effectively exterminated. DETAILED DESCRIPTION OF THE INVENTION

[0010] The natural pyrethrins (hereinafter sometimes referred to as "the present compounds") of the present invention are described below. Natural pyrethrins include six types of compounds: pyrethrin I, pyrethrin II, cinerin I, cinerin II, jasmoline I, and jasmoline II. Natural pyrethrins are typically obtained as an extract or as a dried powder of pyrethrum, which is obtained by extracting only the flower buds of pyrethrum (scientific names: Tanacetum cinerariifolium or Chrysanthemum cinerariaefolium) from the dried and pulverized flower buds using an appropriate solvent capable of dissolving the active ingredient, such as an organic solvent such as methanol. In addition to the six types of compounds, natural pyrethrins may also contain plant-derived impurities (such as fatty acids and flavonoids).In addition to the white daisy, plants from which natural pyrethrins can be obtained include Calendula officinalis, Chrysanthemum coccinum, Tagetes erecta, Tagetes minuta, Zinnia elegans, and Zinnia linnearis (Reference 1: Adnane, H. Alain, C. & Chantal, B. 2000. The Production of Pyrethrins by Plant Cell and Tissue Cultures of Chrysanthemum cinerariaefolium and Tagetes Species. Critical Reviews in Plant Sciences, 19(1):69-89; Reference 2: Kudakasseril, GJ and Staba, EJ 1988. Insecticidal phytochemicals. In: Cell Culture and Somatic Cell Genetics of Plants. pp. 537-552. Constabel, F. and Vasil, I.K., Eds., Academic Press, New York. Reference 3: John E. Casida, Gary B. Quistad. 1995. PYRETHRUM FLOWERS, Production, Chemistry, Toxicology, and Uses. pp. 123-125, Oxford University Press.) The plant species and varieties that serve as the source of the natural pyrethrins used in the present invention are not limited to those mentioned above. The plant cultivation method, cultivation conditions (weather, place of origin, soil type, etc.), harvest time, harvest part, harvesting method, washing method, extraction method, and purification method are not particularly limited. In addition, the natural pyrethrins used in the present invention also include, for example, natural pyrethrins obtained using a vector into which a gene encoding a pyrethrin biosynthetic enzyme has been inserted. The weight ratios of the six compounds in natural pyrethrins, pyrethrin I, pyrethrin II, cinerin I, cinerin II, jasmolin I, and jasmolin II, are not particularly limited and may be set at any weight ratio within the range of 0.001 to 99%, but are typically contained in weight ratios of 10 to 70% pyrethrin I, 10 to 70% pyrethrin II, 1 to 20% cinerin I, 1 to 20% cinerin II, 1 to 20% jasmolin I, and 1 to 20% jasmolin II. Specific examples of the blending ratios (parts by weight) are as follows: Weight ratio [pyrethrin I:pyrethrin II:cinerin I:cinerin II:jasmolin I:jasmolin II] = 38.0:35.0:7.3:11.7:4.0:4.0 (Reference 3) Furthermore, natural pyrethrins are usually plant extracts, and therefore may contain, in addition to the six compounds, plant-derived impurities and auxiliary ingredients such as solvents, stabilizers, etc. The content of the six compounds in natural pyrethrins is usually 10 to 99%, preferably 15 to 90%, and more preferably 20 to 85%. Examples of natural pyrethrins include those containing pyrethrin I (total amount of pyrethrin I, cinerin I, and jasmolin I) and pyrethrin II (total amount of pyrethrin II, cinerin II, and jasmolin II) in amounts of 20 to 40% pyrethrin I and 12 to 31% pyrethrin II.

[0044] Formulation Example 6 0.1 parts of the present compound and 39.9 parts of kerosene are mixed and dissolved, placed in an aerosol container, and filled with 60 parts of liquefied petroleum gas (a mixture of propane, butane, and isobutane; saturated vapor pressure: 0.47 MPa (25°C)) to obtain a formulation.

[0045] Formulation Example 7 0.2 parts of the present compound, 50 parts of pyrethrum extract residue powder, 30 parts of Tabu powder, and 19.8 parts of wood flour are mixed, an appropriate amount of water is added, and the mixture is kneaded. The mixture is then extruded into a plate-shaped sheet, and then wound into a spiral shape using a die-cutting machine to obtain a formulation.

[0046] Next, the efficacy of the present compound against harmful annelids will be shown by test examples. In the following test examples, the tests were carried out at 25°C.

[0047] Test Method 1 Acetone solution prepared so that the test compound was 50 ppm was poured into a 20 mL container, and the test compound was 2.5 mg / m 2 The inner surface of the container is uniformly coated with the solution, and then dried. A leech (Haemadipsa zeylanica) approximately 1-3 cm in total length is placed in the container and the lid is closed. After a predetermined time has passed, the condition of the leech is examined and the mortality rate is calculated using the following formula. Individuals that do not respond normally to breath blowing on them (no active exploration, inability to walk, writhing around, lethargic and unresponsive, etc.) are considered dead. Mortality rate (%) = (number of deaths / number of test insects) × 100

[0048] Test Example 1-1 The results of the test carried out according to Test Method 1 are shown in Table 1. [Table 1] The total concentration of natural pyrethrins, pyrethrins I and II, was set at 50 ppm. This indicates that natural pyrethrins have a faster-acting extermination activity against harmful annelids than the repellent components described in Patent Document 1, such as deet, metofluthrin, or transfluthrin.
