The invention provides a triazole derivative represented by a general formula ##STR1## (wherein R.sup.1 is an alkyl group, X is a hydrogen atom, a halogen atom or an alkyl group, n is an integer of 1-5, Y is a halogen atom, a nitro group or an alkyl group, and m is an integer of 2-5) as well as insecticide and acaricide containing the same as an active ingredient. The triazole derivatives according to the invention exhibit an excellent effectiveness against harmful pests, particularly aphids and mites.

Triazole derivatives, insecticide, acaricide and methods thereof

A novel triazole derivative for use in an insecticide or an acaricide has a general formula [I]: ##STR1## (wherein R.sup.1 is an alkyl group, X is a hydrogen atom, a halogen atom or the like, n is an integer of 1-5, A is an oxygen atom, a sulfur atom or the like, k is 0 or 1, R.sup.2 is a hydrogen atom, a halogen atom or the like, m is an integer of 1-5) and controls various injurious insects and mites, particularly mites and aphids without damaging crops.
