Fused heterocyclic compounds having a cycloalkylpyridyl group or salts thereof, agricultural and horticultural insecticides containing the compounds, and methods of use thereof
An object of the present invention is to provide and develop novel agricultural and horticultural insecticides in view of the still immense damage caused by insect pests etc. and the emergence of insect pests resistant to existing insecticides in crop production in the fields of agriculture, horticulture and the like. Provided are a condensed heterocyclic compound represented by the general formula (1): {wherein R 1 represents an ethyl group, R 2 represents a cycloalkyl group, R 3 represents a haloalkyl group, A, A 2 and A 3 each represent a nitrogen atom or a CH group, A 1 represents N-Me, m represents 0 or 2, and n represents 1} or a salt thereof； an agricultural and horticultural insecticide comprising the compound or a salt thereof as an active ingredient； and a method for using the insecticide.
