Abstract

PROBLEM TO BE SOLVED: To obtain the subject repellent by using an inexpensive natural material with slight problems including environmental pollution. SOLUTION: This repellent against Musca domestica contains at least geranium oil as repelling ingredient, wherein the geranium oil is a plant essential oil which is obtained by e.g. steam distillation of a plant belonging to the genus Pelargonium such as Pelargonium radula, is available relatively inexpensively, highly safe to humans and livestock, and slight in environmental influence as well.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a house fly repellent using natural materials.

[0002]

2. Description of the Related Art Heretofore, as one of means for controlling the damage of various pests, a search for a substance causing a negative running property, that is, a repellent has been widely performed. In particular, research on blood-sucking pests such as mosquitoes, lice, mites and the like has been advanced, and for example, dimethyl phthalate, 2-ethyl-1,3-hexanediol, indalone, dimethyl carbate, N, N-
Repellents containing repellent components such as propyl diethylsuccinate, benzyl benzoate, N-butylacetanilide, 2-butyl-2-ethyl-1,3-propanediol have been developed. Essential oils such as citronella oil and eucalyptus oil are also known to have a repellent effect on these blood-sucking pests.

[0003]

However, since insects and mites generally have specificity with respect to repellency, substances that are effective against mosquitoes, lice, ticks, etc. do not always exert repellent effects on other insects. Absent. For example, it was found that the above-mentioned various components did not show a sufficient repellent effect on house flies. on the other hand,
House flies are not blood-sucking pests, but they are pests that transmit various infectious diseases, etc., and because they are omnivorous and fly around human territories, causing discomfort. In addition to strong fertility and eradication, the use of powerful insecticides has recently become obsolete, and as a result repelling house flies made of natural materials that are safe, inexpensive, and have few problems such as environmental pollution. Agents are becoming more demanding. The present invention has been achieved as a result of research for solving the above-mentioned problems, and accordingly, an object of the present invention is to repel houseflies made of natural materials that are safe, inexpensive, and have few problems such as environmental pollution. To provide an agent.

[0004]

The above object can be attained by providing a house fly repellent containing at least geranium oil as a repellent component.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention has been achieved by the discovery that geranium oil, a natural essential oil, specifically exhibits a persistent repellent effect on house flies. Here, the geranium oil is a plant essential oil obtained from a plant of the genus Pelargonium, such as Niotei mulberry, by, for example, steam distillation.
It is relatively inexpensive, safe for humans and animals, and has little impact on the environment.

[0006] A test was conducted to compare the repellent effect of geranium oil on houseflies with other plant essential oils and a control sample without essential oil (control) as follows. Six plastic dishes (inner diameter 9 cm) were prepared, and geranium oil (Example 1), eucalyptus oil (Comparative Example 1),
A filter paper (diameter 9 cm) impregnated with a fixed amount of hinoki oil (Comparative Example 2), rose oil (Comparative Example 3), anise oil (Comparative Example 4), or citronella oil (Comparative Example 5) was spread, and the center of each was spread. A petri dish (diameter 6 cm) containing a mixture of sugar and powdered milk as a housefly feed was prepared. As controls, six samples (controls) prepared in the same manner except that water was impregnated instead of the essential oil described above were prepared.

A set of two wire mesh cages (22 cm × 22 cm × 22 cm) each containing 100 house flies, which were bred under fixed conditions and fasted with water only for 24 hours, were prepared.
Prepare a set, put each sample of Example 1 or Comparative Examples 1 to 5 in the center of one cage of each set, put a control sample in the center of the other cage, for each set, immediately after the start of the repellent test, After 5 minutes and 10 minutes, the number of house flies flying on each sample was counted. The repellent rate (%) after 10 minutes was determined by the following formula. Repellency (%) = (control-sample) / (sample + control) x 10
0 The results are shown in Table 1.

[0008]

[Table 1]

From the above results, it was clear that geranium oil had a specifically high repellent effect on house flies, and it was found that the effect was persistent.

The house fly repellent of the present invention may be in any product form as long as it contains at least geranium oil as one component. Examples of the product form containing geranium oil include, for example, a porous ceramic, a luminous cord (fluolite), a continuous foamed plastics, wood, absorbent cotton, a sponge, and a liquid containing geranium oil alone or a liquid containing at least geranium oil as one component. Solid products impregnated in a permeable carrier such as nonwoven fabric or paper, tablet products formed by mixing and compressing geranium oil with a powdered carrier such as talc, zeolite, wax, etc., and certain concentrations of geranium oil in an organic solvent such as alcohol Liquid or gel-like product dissolved in the above, or an aerosol product using the above-mentioned solution, an emulsion or cream-like product containing geranium oil and a surfactant, a smoked / fumigated product containing geranium oil, or a so-called fly ribbon Products such as paper ribbons and strings impregnated with geranium oil and suspended from the ceiling. Al are those both within the scope of the present invention.

[0011]

The repellent for houseflies of the present invention contains at least geranium oil as a repellent component, and therefore has a particularly high and long-lasting repellent effect on houseflies and is relatively inexpensive natural essential oil. Not only is it safer for humans and animals, but it can also be expected to increase the comfort of humans as a type of aromatherapy. The effect on the natural environment is small.
