The efficacy of Diflubenzuron against the body louse (Damalinia limbata) of Angora goats.
The efficacy of an insect growth regulator, Diflubenzuron, to control biting lice (Damalinia limbata) on Angora goats was investigated. Lice on goats which were dipped in a concentration of 625 g Diflubenzuron to 1,000 1 water and then kept in quarantine was eradicated after a single treatment. Nymphs remained present on these goats up to 4 weeks and adult lice up to 8 weeks post-treatment. A single treatment provided greater than 90% reduction in nymphal stages from Week 6 to Week 16 post-treatment in treated goats continuously exposed to reinfestation. The treatment reduced adult louse infestations on these goats by 78-94% through Weeks 6-16 post-treatment. At the end of the trial (24 weeks post-treatment), these goats had 88% fewer nymphs and 84% fewer adult lice compared with untreated control goats.
