2. Description of the Related Art In the field of agriculture and horticulture, various insecticides for controlling various pests have been developed and put to practical use. However, conventionally used agricultural and horticultural insecticides are not always satisfactory in terms of insecticidal effect, insecticidal spectrum, residual efficacy, and the like. In addition, it cannot be said that the requirements such as the reduction in the number of applications and the amount of applied medicine are satisfied. In addition, the appearance of pests that have acquired resistance to conventional pesticides has also become a problem. For example, vegetables,
In cultivation of fruit trees, flowers, tea, wheat and rice,
Various pesticides of various strains, for example, carbamates, pyrethroids, benzoylureas, organochlorines, and various pests that have acquired resistance to organophosphorus pesticides, have appeared in various places and are caused by these pests. The control of various pests is becoming more difficult year by year. There is a strong need for the development of a novel insecticide that exhibits a sufficient control effect at a low dose even with respect to various pests that have acquired resistance to conventional agricultural and horticultural insecticides, and that has little adverse effect on the environment. As for the acaricide, the development of a highly safe acaricide is also expected, which shows an excellent control effect on mites which are resistant to conventional acaricides.
