In crop production in the fields of agriculture, horticulture and the like, the damage caused by insect pests etc. is still immense, and insect pests resistant to existing insecticides have emerged. To solve the problems, the present invention has been made, and an object of the present invention is to develop and provide a novel agricultural and horticultural insecticide. The present invention provides a heterocycle-bound condensed heterocyclic compound represented by the general formula (1): ##STR00001##
{wherein R.sup.1 represents an ethyl group, R.sup.2 represents a haloalkyl group, A.sup.1 represents a N-methyl group, A.sup.2 and A.sup.3 represent a nitrogen atom, n represents 1, m represents 2, and Q represents an oxadiazole}, 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.

The present invention relates to compounds of Formula (I), wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4 and G are as defined herein. The invention further relates to herbicidal compositions which comprise a compound of Formula (I), to their use for controlling weeds, in particular in crops of useful plants.
