Repellent efficacy of DEET and KBR 3023 against Amblyomma hebraeum

The bont tick, Amblyomma hebraeum cooking is the main vector of Rickettsia africae, the etchant of African swine fever tick in southern Africa. Unlike most other hard ticks members Bont who are looking for a characteristic attack Bed behavior. The efficacy of topical lotions 20% DEET (diethyl-3-methylbenzamide), the reference substance currently repulsive viewed and KBR 3023, a compound piperidine recently developed was evaluated against A. nymphs high hebraeum laboratory on contracts fingers. Both substances repelled> 85% of the nymph attacks on 0 and 1 h after treatment. A 2, 3 and 4 hours were the repellent DEET efficiencies 84%, 68% and 71%, while the KBR 3023 were 56, 55 and 54%. The differences between the two test substances were statistically significant only for 2 h after treatment. This first study repellents against A. hebraeum topical indicates that 20% DEET and KBR 3023 Lotions for 2 h are effective or 1, but the decrease repellent efficiencies thereafter.
