FIELD: organic chemistry.

SUBSTANCE: invention relates to a fused heterocyclic compound of general formula (1) or its salt, where R¹, R^2a and R^2b may be the same or different from each other and each represents (a1) a hydrogen atom; (a3) (C₁-C₆) an alkyl group; (a4) a halogen (C₁-C₆) alkyl group; or (a5) a phenyl group, except where R¹, R^2a and R^2b are all hydrogen atoms, Et is an ethyl group, and Q is any from the groups represented by the following Q-1–Q-3, where R³ represents (b1) halogen (C₁-C ₆) alkyl group; or (b4) a halogen (C₁-C₆) alkylsulfinyl group; each black circle represents a binding position and m represents 1. The invention also relates to an agricultural or horticultural insecticide, an agent for combating ectoparasites or endoparasites of animals based on the compound of formula (1), a method of using the said insecticide or agent.

EFFECT: development of an agricultural or horticultural insecticide, as well as an agent for combating ecto- or endoparasites based on the compound of formula 1, which has almost no effect on non-target organisms, such as natural predators and beneficial insects, and controls ectoparasites and endoparasites of animals.
