The present invention addresses the problem of developing and providing a novel agricultural/horticultural insecticide in view of the fact that, in crop production, such as agriculture and horticulture, damage by harmful insects, etc., is still serious, and in view of factors such as the evolution of harmful insects that are resistant to existing chemicals. The present invention provides a benzoxazole compound represented by general formula (1) or a salt thereof, an agricultural/horticultural insecticide comprising the same as an active ingredient, and a method for using the same. (1) (In the formula, R1 represents a trifluoromethoxy group or a trifluoromethylsulfinyl group, R2 represents a hydrogen atom, and m represents 2.)
