RESISTANCE PREVENTION

Risk of resistance? YES

There are no reports on resistance of horse body lice to triflumuron. However, sheep body lice of the same genus (Bovicola) have developed resistance to several benzoylureas (diflubenzuron, triflumuron) and it must be assumed that horse body lice may develop resistance if submitTed to prolonged selection pressure with such products. Thus it is a good idea to periodically change the active ingredient (rotation) used against these parasites.

COMMENTS

LICE 'N' SIMPLE is a pour-on for horses from JUROX that containins generic trifumuron.

Triflumuron is a broad-spectrum insect growth regulator (IGR) belonging to the benzoylphenyl-ureas introduced in the 1980s (by BAYER). It is effective against immature stages (larvae, nymphs, etc.) of numerous insects but not against adult stages. It is scarcely used in sheep and horses but only in Australia and New Zealand, not in Europe or the US. It is not used so far in other livestock or in pets. It is also used moderately against agricultural and household pests.

It is important to understand that this and other products containing insect growth regulators do not kill adult lice that may infect animals at the moment of treatment, i.e. they don't have a knock-down effect. What they do is to prevent further development of immature stages. Larvae and/or nymphs fail to molt to the next stage and die. Thus infected animals treated may need a few weeks to become free of lice.
