2. Description of the Related Art Conventionally, for the purpose of protecting plants and grains, humans and livestock from hygiene pests such as flies and cockroaches, an extremely large number of sanitary substances such as amides, esters, glycols, synthetic pyrethroids and imidazoles have been used. Pesticides have been used. However, these sanitary pest control agents are not always satisfactory, not only in terms of efficacy such as insecticidal effect, insecticidal spectrum, residual effect, etc., but also in terms of safety such as toxicity to aquatic animals and warm-blooded animals or environmental pollution due to residues. It doesn't work. In addition, as a result of repeated use of these drugs, resistance to the drug develops in various sanitary pests, the efficacy decreases, or the effect is hardly recognized at the usual treatment dose, making it difficult to control Is often the case. In addition, some of these drugs have a repellent effect against pests, making it difficult to use preparations mixed with bait of target pests. It is difficult to reach a fundamental decrease.
