Abstract

The present invention relates to an acid amid derivative of the formula (I) or a salt thereof:

wherein A is phenyl which may be substituted by X, benzyl which may be substituted by X, naphthyl which may be substituted by X, a heterocyclic group which may be substituted by X, a fused heterocyclic group which may be substituted by X, indanyl (the indanyl may be substituted by halogen, alkyl or alkoxy) or tetrahydronaphthyl (the tetrahydronaphthyl may be substituted by halogen, alkyl or alkoxy), B is alkyl, cycloalkyl, phenyl which may be substituted by Y, a heterocyclic group which may be substituted by Y, or a condensed heterocyclic group which may be substituted by Y, each of R₁ and R₂ is alkyl, cyano or —CO₂R₁₄, or R₁ and R₂ may together form a 3- to 6-membered saturated carbocyclic ring, R₃ is hydrogen, alkyl, alkoxyalkyl, alkylthioalkyl, —COR₁₅, —S(O)mR₁₆ or —S(O)nNR₁₇R₁₈, which is useful as an active ingredient of pesticides.
