Structure-activity relationships of novel 1-alkoxymethyl-2,4,5-trihalimidazole compounds against a wild colony of German cockroaches resistant to pyrethroids (O-colony) are reported.Among them, 1-methoxymethyl-2-bromo-4,5-dichloroimidazole and 1-isopropoxymethyl-2-bromo-4,5-dichloroimidazole were very effective by a filter paper contact method.The variation in insecticidal activity is shown to be related to the length and branching of the alkyl chain of the 1-substituents.Above all, 1-(4-bromobutoxymethyl)-2-bromo-4,5-dichloroimidazole and 1-(4-bromo/chlorobutoxymethyl)-2,4,5-trichloroimidazole exhibited low acute oral toxicity to mice and good activity by a heating fumigant test, representing one of the practical applications.The trihaloimidazole derivatives had almost two-fold higher activity against O-colony insects than against the susceptible strain.

A bromodichloroimidazole derivative represented by the formula STR1 wherein R represents a C1 -C4 alkyl, C2 -C5 alkyl substituted by one or more halogen atoms, C3 alkenyl, C3 alkenyl substituted by one or more halogen atoms, C3 alkynyl or C3 alkynyl group substituted by one or more halogen atoms; its production; and an insecticidal and/or acaricidal composition containing it as an active ingredient.
