The present study aimed to evaluate the acaricidal action of the chemically modified essential oil of Cymbopogon spp. and Corymbia citriodora on Rhipicephalus (Boophilus) microplus. Citronellal was converted into N-butylcitronellylamine and in N-prop-2-inylcitronellylamine, analogs of juvenoids, by reductive amination using butylamine (N1 to N3) and propargylamine (N4 to N7). In vitro assays included the adult immersion, and larval packet tests. Engorged females were weighed in groups of 10 and tested in three replicates for six concentrations. They were immersed in the modified oils or control solution and incubated. In the larval packet test, the same substances and concentrations were evaluated in three replicates. In the in vivo test, six pastured heifers naturally infested with R. (B.) microplus were used per treatment: negative control, positive control (amitraz, Triatox®), original oil of C. citriodora at 1.5%, and modified oil containing 0.9% N-prop-2-inylcitronellylamine (N7). Ticks were counted in the right side of the body in 24 animals from day D-3 to D21. LC50 and LC90 were obtained by Probit analysis, while the in vivo results were log transformed and compared using the Tukey test. Among the nitrocellylamines tested in vitro, N6 was most effective on the engorged females (100% efficacy at 50 mg/mL) and N7 on the larvae (100% efficacy at 6.25 mg/mL). In the test with larvae, the original oil of C. citriodora was less effective than the counterpart modified oil (N7), proving that the chemical modification optimized its effect. In the in vivo test, no significant difference was observed between N7 and the negative control. The average numbers of ticks on the animals? right side were 32.8, 8.1, 37.9 and 35.4 for the negative control, positive control, original oil and N7, respectively. The chemical modification improved the efficacy in vitro, but it was not observed in vivo, perhaps due to the low stability of the amines under field conditions. The evaluation carried out here has not been previously studied, so this concept expands the horizon for research into chemically modified substances for parasite control and shed light on the challenges to find effective formulations and application methods.

O presente trabalho foi desenvolvido no municipio de Paranaita, norte de Mato Grosso, em regiao de Floresta Tropical Umida, tipo aberta, tendo com objetivo determinar a ocorrencia de epifitas vasculares, sua abundancia e distribuicao vertical nas plantas hospedeiras; realizado no mes de junho de 1995. Para tanto, amostraram-se plantas com CAP > 30cm estimando-se altura do hospedeiro metro a metro desde o solo ate a copa, numa area de floresta aberta (1 ha) e em duas areas de capoeiras de 5 e 12 anos (1 ha). Foram encontrados 321 individuos, dos quais 275 na Floresta, 46 na Capoeira II (12 anos) e nenhuma na Capoeira I (5 anos), pertencentes as familias Araceae, Bromeliaceae, Orquidaceae e a divisao Pteridophyta. Verificou-se que tanto na Floresta quanto na Capoeira II, a familia Araceae e as Pteridofitas, foram as mais importantes, concentrando-se nos estratos de 0 a 5 m, sendo que as familias Orquidaceas e Bromeliaceas ocorreram preferencialmente nos estratos superiores entre 7 a 10 m. Constatou-se que tanto na Floresta Aberta quanto na Capoeira II, em areas de vegetacao mais densa, proximas a rios e igapos, ha maior numero de epifitas comparadas as areas pertubadas com presenca de bambus e lianas. O maior numero de especies vasculares foi encontrado na floresta, o que pode estar relacionado a fatores abioticos e bioticos, bem como a conservacao desses ambientes que estao afetando e regulando a comunidade epifita. |
