“…Chemical ecology of tick-host interactions Rechav 1979). The principal components of the AAA pheromone for A. variegatum and A. hebraeum include 2-nitrophenol (o-nitrophenol), methyl salicylate, , 2,6-dichlorophenol, with some differences in presence and abundance between species (Diehl et al1991, Lusby et al 1991, Schöni et al 1984. In general, 2-nitrophenol and methyl salicylate stimulate long range, interspecific attraction and aggregation; whereas, methyl salicylate and nonanoic acid induce attachment (Lusby et al 1991).…”

“…Essa repelência foi acima de 80%. De acordo com Maranga et al (2003), na formulação de um feromônio sintético de atração-agregação-fixação para A. variegatum encontra-se o salicilato de metila e, de acordo com Schoni et al (1984), o salicilato de metila sozinho, testado sobre A. variegatum, não provocou nenhuma alteração comportamental sobre a espécie. Nesse mesmo trabalho, cita-se a mistura do σ nitrofenol com salicilato de metila e ácido pelargônico, uma vez que, para a ocorrência dessa atividade feromonial, é necessária a mistura desses três componentes.…”

Verificou-se a atividade repelente do timol, mentol, ácido salicílico e salicilato de metila sobre larvas de Boophilus microplus. Essas substâncias foram usadas em emulsões em dimetilsulfuxido aquoso a 1% ou solução aquosa. Para cada substância foram testadas três concentrações, 1,0%; 0,5% e 0,25%, com cinco repetições cada. Cerca de 100 larvas, com 21 dias de idade, foram inseridas na base de hastes de madeira para avaliação da repelência, a cada duas horas, totalizando 12 horas. As concentrações mais elevadas apontaram que as quatro substâncias causaram alteração no comportamento das larvas. Timol, com mortalidade de 65% e 35% de repelência e mentol e salicilato de metila, ambos com 80% de repelência foram os mais eficientes.

“…Here, samples of ground litter, animal burrows, and crevices in and under tree bark were made by means of the vacuum device, and by employing C02 traps that emitted synthetic pheromone vapors (Butler et al, 1984). The pheromone mixture used approximated the assembly-aggregation pheromone of Amblyomma variegatum (Schoni et al, 1984), which is known to strongly attract both sexes ofA. hebraeum on the host (Rechav et al, 1982).…”

No methods have previously been available for the field sampling of unfed adults of Amblyomma hebraeum. We released 2000 unfed adults into a 5-m2 area in mopane woodland in southeastern Zimbabwe. The ticks sought shelter beneath the debris on the soil surface but emerged and became active in host seeking when stimulated. Effective stimuli were the odours of cattle and sheep and high concentrations of carbon dioxide from dry ice. The ticks did not respond to low concentrations of carbon dioxide, vibrations generated by stamping the ground with poles, or two volatile components of ox breath known to attract tsetse flies. The presence of humans in the release area also had little or no effect in stimulating the ticks. As adults of A. hebraeum are large and conspicuous they can easily be collected from the soil surface, either manually or using a vacuum device, after stimulation by cattle or the release of high concentrations of carbon dioxide.
