“…(B.) microplus (SRIVASTAVA et al, 2008;MAGADUM et al, 2009). The biochemical effects of this extract over the cattle tick remains unclear, but Habluetzel et al (2007) found that the extract produced a reduction in the survival of the larvae and adults and also interfered with oviposition and oogenesis, behavior, dietary process, and growth of arthropods (SCHMUTTERER, 1990;MORDUE;NISBET, 2000;BROGLIO-MICHELETTI et al, 2009.…”

The cattle tick Rhipicephalus (Boophilus) microplus is responsible for major losses in the Brazilian livestock, mainly due to reduction in cattle productive performance. Resistance development to major classes of acaricide widely used nowadays has been extensively reported, as well as the occurrence of residues from these compounds in animal products and the environment. This study aimed to evaluate the efficiency of acaricides on R. (B.) microplus collected from rural properties in the North-Central region of Bahia State. Ticks were collected in several cattle farms in the cited region, and an in vitro acaricide efficiency assay was performed based on the immersion of ticks in acaricide solutions made according to manufacturers' recommendations. The results obtained in the experiments indicated varying degrees of efficiency of the several bases studied, with the products benzofenilurea, macrocyclic lactone and fipronil showing the highest levels of efficiency, 100%, 100% and 97.34%, respectively. It was possible to conclude that, for the region studied, there are different degrees of commercial acaricides efficiency, and many present less than 95% effectiveness, value determined as acceptable by the Brazilian legislation.Keywords: Ticks, cattle, drug resistance, acaricide, Brazilian Northeast. ResumoO carrapato Rhipicephalus (Boophilus) microplus é responsável por grandes perdas na pecuária brasileira, principalmente devido à redução no desempenho produtivo dos animais. A resistência do parasita a diferentes classes de acaricidas tem sido amplamente relatada, bem como os problemas de ocorrência de resíduos desses compostos em produtos de origem animal e no ambiente. Esse estudo teve como objetivo avaliar a eficiência de diversos acaricidas sobre populações de R. (B.) microplus provenientes de propriedades rurais da Região Centro-Norte do Estado da Bahia, Brasil. Teleóginas ingurgitadas foram colhidas em diferentes propriedades da região e submetidas a ensaio in vitro de eficiência de acaricidas, baseado na imersão dos carrapatos em soluções de acaricidas feitas seguindo as recomendações dos fabricantes. Os resultados obtidos indicam níveis variados de eficiência das bases estudadas, com os acaricidas benzofenilureia, lactona macrocíclica e fipronil apresentando os índices mais altos de eficiência, 100%, 100% e 97.34%, respectivamente. Pode-se concluir que, para a região estudada, os acaricidas apresentam níveis diversos de eficiência, e muitos deles possuem eficácia de menos de 95%, como recomendado pela legislação brasileira.

This study was conducted to determine parasiticidal efficacy of seven ethnomedicinal plants against Sarcoptes scabiei var. caprae of goats using in vivo and in vitro techniques. In vitro techniques for evaluation of efficacy of medicinal plants essential oils and fixed oils of seven medicinal plant extracts diluted at different concentrations (essential oils from 2.5% to 0.15625% and fixed oils from 160 mg/ml to 5 mg/ml) were added to petridishes containing adult stage of Sarcoptes scabiei var. caprae. After 3 h of contact, all concentrations of essential oil of Eucalyptus globulus and Cymbopogon citractus showed a good in vitro acaricidal efficacy as compared with the non-treated controls (p<0.05). However, Nicotiana tobacum fixed oil had significant (P<0.05) effect at a concentration of 160 mg/ml and 80 mg/ml. Pyrethrum cineraria folium fixed oil showed lower acaricidal efficacy (P<0.05) in all the concentrations of the extract as compared to the reference drugs. In vivo techniques undertaken for evaluation of efficacy essential oil of Eucalyptus globulus and Cymbopogon citractus at a concentration of 0.625% in 2% Tween 80 on two groups of (six animals each) Sarcoptes scabiei var. caprae infested goats were topically treated two times at 14 days interval and its compared with non-treated and treated (diazinone and ivermectin) controls of six goats in each group. The infected goats treated with the essential oils were cured completely. Statistically insignificant (p>0.05) difference was never observed in mite count, Mean Recovery Response (MRR) and degree of Skin Lesion Quality (SLQ) between goats treated with plant extracts and those treated with diazinone and ivermectin. Therefore, Eucalyptus globulus and Cymbopogon citractus extracts should be licensed for the treatment of Sarcoptes scabiei var. caprae.

Different species from the genus Tephrosia were studied for larvicidal, insecticidal, and antifeedant activities.…”

Comparative in vitro anti-tick efficacy of commercially available products and newly developed phyto-formulations against field collected and resistant tick lines of Rhipicephalus (Boophilus) microplus

et al. 2016

Rhipicephalus (Boophilus) microplus is considered as one of the most widely distributed tick species ecto-parasitizing on livestock and causes fatal diseases with significant production loss. To address the problem of controlling acaricide resistant tick infestations on animals, attention has been paid to develop eco-friendly phytoacaricides. The present study was undertaken to evaluate the comparative anti-tick activities of commercially available herbal and chemical products with chemically characterized phyto-formulations developed recently against field ticks and resistant tick lines of R. (B.) microplus. The chemical product Butox Ò Vet was found nearly passive against all the tested resistant tick lines. However, one of the commercial polyherbal product, Zerokeet Ò showed an efficacy (E%) of 41.8-75.4 % ( X ¼ 63:5 AE 7:4 %) using recommended dilution (1:2) against field ticks and resistant tick lines. However, the other commercial product, Erina Ò EP has very limited efficacy against all the tested tick. In comparison, the newly developed phyto-formulation, NBA/13/B/2 and NAC-01 conferred an E% of 82.4-91.3 % ( X ¼ 85:9 AE 2:1 %) and 62.3-94.6 % ( X ¼ 80:0 AE 8:1 %), respectively, against tested resistant ticks. Results indicated higher marketing potentiality of newly developed formulation in the existing tick problem scenario.
