“…Abdel-Shafy and Zayed (2002) and Williams (1993) also concluded that neem oil could be used for tick control at economical concentrations of 1.6 to 3.2%. Souza et al (2000) produced a concentrated emulsion of green fruits that was tested at concentrations of 0.25 and 0.5% and showed efficacies ranging from 46.7 to 82.6% and from 16.6 to 89.0%, respectively. Broglio-Micheletti et al (2010) analyzed the efficacies of a neem hexane extract and a 2% oil concentration against R.…”

The control of tick species that affect animal production is vital for the economic welfare of the cattle industry. This study focused on testing the acaricidal activity of the essential oil from the leaves and stems of Tagetes minuta against several Brazilian tick species, including Rhipicephalus (Boophilus) microplus, Rhipicephalus sanguineus, Amblyomma cajennense and Argas miniatus. The chemical composition of the essential oil was determined by chromatography and spectroscopy analyses, which revealed the presence of monoterpenes. The adult immersion test (AIT) and the larval packet test (LPT) were used to evaluate the efficacy of T. minuta essential oil in tick management at concentrations of 2.5, 5, 10, 20 and 40%. The results demonstrated that the T. minuta essential oil had over 95% efficacy against four species of ticks at a concentration of 20%. These results suggest that the essential oil of T. minuta could be used as an environmentally friendly acaricide.Keywords: Tagetes minuta, ticks, phytotherapy, control. ResumoO controle de carrapatos que causa impacto na produção de bovinos possui importância econômica para a cadeia produtiva. Neste trabalho objetivou-se testar a atividade acaricida do óleo essencial das folhas e caules de Tagetes minuta contra várias espécies de carrapatos brasileiros, incluindo Rhipicephalus (Boophilus) microplus, Rhipicephalus sanguineus, Amblyomma cajennense e Argas miniatus. A composição química do óleo foi determinada por GC-MS e análises de espectroscopia de RMN, que revelaram a presença de monoterpenos. Na avaliação destas substâncias no controle do carrapato foram empregados os testes de imersão de adulto (TIA) e o de pacote de larvas (TPL) para o extrato de óleo de T. minuta nas concentrações de 2,5%; 5%; 10%; 20% e 40%. Os resultados do TPL e TIA demonstraram que o óleo essencial na concentração de 20% de T. minuta apresenta eficácia superior a 95% nas quatro espécies de carrapato. Estes resultados sugerem que o óleo essencial de T. minuta pode ser usado como um acaricida eficaz e com baixo impacto ambiental.

“…minuta has been shown to be antimicrobial (SOUZA et al, 2000), insecticidal and acaricidal (TOMOVA et al, 2005;. The terpenes in the T. minuta oil are toxic to mosquitoes (MACÊDO et al, 1997) and have been reported to have aphicidal properties (TOMOVA et al, 2005).…”

“…camara, belonging to the Verbenaceae family, exhibits antimicrobial activity (DEENA;THOPPIL, 2000), efficacy against termite workers (VERMA; VERMA, 2006) and has a nematostatic effect on the phytonematode Meloidogyne incognita (DIAS et al, 2000). T. minuta, from the Asteraceae family, has fungitoxic effects (ROZWALKA et al, 2008), activity against Anopheles stephensi larvae (HADJIAKHOONDI et al, 2005), antibacterial activity (SOUZA et al, 2000) and effect on H. contortus egg and larvae (MACEDO et al, 2012). A. zerumbet, from the Zingiberaceae family, exhibits antioxidant (ELZAAWELY et al, 2007), antibacterial and antifungal activities (VICTÓRIO et al, 2009).…”

In vitro effects of AbstractPhytotherapy can be an alternative for the control of gastrointestinal parasites of small ruminants. This study evaluated the efficacy of Alpinia zerumbet, Coriandrum sativum, Tagetes minuta and Lantana camara essential oils by two in vitro assays on Haemonchus contortus, an egg hatch test (EHT) and larval development test (LDT). No effect was observed for L. camara in the EHT. A. zerumbet, C. sativum and T. minuta essential oils exhibited a dose-dependent effect in the EHT, inhibiting 81.2, 99 and 98.1% of H. contortus larvae hatching, respectively, at a concentration of 2.5 mg mL -1 . The effective concentration to inhibit 50% (EC50) of egg hatching was 0.94, 0.63 and 0.53 mg mL -1 for A. zerumbet, C. sativum and T. minuta essential oils, respectively. In LDT, L. camara, A. zerumbet, C. sativum and T. minuta at concentration of 10 mg mL -1 inhibited 54.9, 94.2, 97.8 and 99.5% of H. contortus larval development, presenting EC50 values of 6.32, 3.88, 2.89 and 1.67 mg mL -1 , respectively. Based on the promising results presented in this in vitro model, it may be possible use of these essential oils to control gastrointestinal nematodes. However, their anthelmintic activity should be confirmed in vivo.Keywords: Phytotherapy, anthelmintic, gastrointestinal nematodes. ResumoFitoterapia pode ser uma alternativa para o controle de parasitas gastrintestinais de pequenos ruminantes. Este estudo avaliou a eficácia dos óleos essenciais de Alpinia zerumbet, Coriandrum sativum, Tagetes minuta e Lantana camara sobre Haemonchus contortus através de dois testes in vitro, teste de eclosão dos ovos (TEO) e teste de desenvolvimento larval (TDL). Nenhum efeito foi observado para L. camara no TEO. Os óleos essenciais de A. zerumbet, C. sativum e T. minuta exibiram um efeito dose dependente no TEO inibindo a eclosão das larvas de H. contortus em 81,2, 99 e 98,1%, respectivamente, na concentração de 2,5 mg mL -1 . A concentração efetiva para inibir 50% (CE50) da eclosão dos ovos foi de 0,94, 0,63 e 0,53 mg mL -1 para os óleos essenciais de A. zerumbet, C. sativum e T. minuta, respectivamente. No TDL, 10 mg mL -1 de L. camara, A. zerumbet, C. sativum e T. minuta inibiram em 54,9, 94,2, 97,8 e 99,5% do desenvolvimento larvar, apresentando valores de CE50 de 6,32, 3,88, 2,89 e 1,67 mg mL -1 , respectivamente. Com base nos resultados promissores apresentados neste modelo in vitro, pode ser possível a utilização destes óleos essenciais para controlar os nematoides gastrintestinais. No entanto, a sua atividade anti-helmíntica deve ser confirmada in vivo.Palavras-chave: Fitoterapia, anti-helmínticos, nematoides gastrintestinais.

“…This picture requires control of the use of antimicrobials and research into new antimicrobials, with focus on human health and to reduce losses in animal production. Some studies (SOUZA et al, 2000;AVANCINI et al, 2000;CIRAJ et al, 2001;LOGUERCIO et al, 2005) have demonstrated the potential use of plant extracts with bactericidal or bacteriostatic for Salmonella. In the search for alternatives to conventional antibacterials, new plant species should be tested in order to identify which are more efficient as antimicrobial agents.…”
