(57) [Summary] [PROBLEMS] Conventional flea controlling agents for fleas parasitic on animals cannot be said to provide sufficient safety based on selective toxicity to living organisms to which they are applied, and their control effect and immediate effect As a result of intensive studies on the insecticidal activity of N-substituted indole compounds against fleas and safety against mammals including pets, N-substituted indole derivatives, For example, 1- (3-chloro-5-trifluoromethylpyridin-2-yl) -3- (dichlorofluoromethylthio) indole, 1- (2,6-dichloro-4-trifluoromethylphenyl) -3- (dichloro Fluoromethylthio) indole or 1- (2,6-dichloro-4-) Trifluoromethylphenyl) -3- (trifluoromethylthio) indole shows high insecticidal activity and immediate effect, Furthermore, it was found that the toxicity was low for mammals including pets. |
