Abstract: Although a variety of pest control agents have been used for many years, many of these pest control agents have various problems, such as insufficient effectiveness, and restriction on use thereof due to resistance acquired by pests, and the like. Therefore, it is desired to develop a novel pest control agent that is less likely to have such drawbacks. One of objects of the present invention is to provide a highly active compound or a salt thereof against a pest. The present invention relates to an N-(4-pyridyl)nicotinamide compound represented by the following formula (I) (in the formula (I), for each substituent, see Description) or a salt thereof.
