“…These results are in accordance to the ones found in our study because the highest activity of the leaf and flower essential oils occurred against bovine tick larvae. The susceptibility of adult bovine ticks seems to be substantially lower compared to larval bovine ticks submitted to essential oils (Castro et al, 2018). Bovine larvae are more vulnerable than adult females because their cuticle is thinner, allowing the active compounds to penetrate in the tick (El Amri et al, 2014).…”

Baccharis dracunculifolia, native to Brazil and the main source of “green propolis”, has been reported with several biological activities, and may be a source of bovine tick control substituting synthetic acaricides. Objective: to evaluate the in vitro and ex situ acaricidal activity of B. dracunculifolia leaf and flower essential oils against Rhipicephalus microplus. Methodology: the essential oils were extracted by hydrodistillation and analyzed by a gas chromatography coupled to mass spectrometry; the acaricidal activity of the essential oil was evaluated in vitro against adult females and against the egg hatchability; moreover, the acaricidal activity against tick larvae was evaluated in vitro and ex situ. Results: the major class of the essential oils was oxygenated sesquiterpene (55.1% leaves 50.4% flowers) and the main compounds were (21.5% leaves; 20.6% flowers) and spathulenol (21.8% leaves; 20.3% flowers). The essential oil at 500 mg/mL was effective to control egg hatchability with a reduction of egg laying capacity and decrease of number of adult ticks and larvae. The larvicidal activity of the essential oil had LC99.9 from 35 to 37 mg/mL by probit analysis, and the essential oil from 11 to 14 mg/mL presented 85 to 95% of treatment efficiency in the ex situ test. Conclusion: B. dracunculifolia leaf and flower essential oils are stable and have application potential to control bovine ticks.

Egyptian Journal of Veterinary Sciences https://ejvs.journals.ekb.eg/ 47 T HE use of traditional methods to control ectoparasites in livestock is a common practice among Fulani herdsmen. Such methods involve manual removal of ticks, avoidance of tick-infested areas, pasture burning and the use of plants with acaricidal activity. The aim of this study was to document and review acaricidal plants used for the control of ticks by Fulani herdsmen in Wukari Local Government Area (LGA), Taraba State, Nigeria. Open-ended questionnaires and guided dialogue techniques were used to interview 58 Fulani herdsmen across five districts in Wukari LGA. Information collected included the common/vernacular names of the plant species, parts used, methods of preparation and administration and toxicity of the plant species. Extensive literature search was conducted to find extra information on what is known about the identified plants. A total of 22 plant species belonging to 16 plant families were documented as being used for the control of ticks in livestock by the herdsmen interviewed. Information obtained from literature indicate that 86% of the plant species already have documented acaricidal and/or tick repellent properties and 50% have similar ethnomedical uses in other parts of the world. Most of the plants employed by the Fulani herdsmen for tick control appear promising as alternative source to commonly used synthetic acaricides.

Óleos Essenciais com Atividade Acaricida para Controle de Rhipicephalus (Boophilus) microplus no Brasil

No Brasil, a principal espécie de carrapato que compromete a produtividade na criação de bovinos é o ectoparasito hematófago Rhipicephalus (Boophilus) microplus, com perdas econômicas estimadas em aproximadamente 3,24 bilhões de dólares anuais. Tais prejuízos originam-se da perda de sangue do animal, da queda da produtividade, transmissão de agentes infecciosos, baixa eficácia de diversos de produtos carrapaticidas disponíveis no mercado devido ao fenômeno de resistência, entre outros. Este carrapato é vetor dos agentes patogênicos causadores de enfermidades que configura o complexo da tristeza parasitária bovina (TPB). Geralmente, o controle desse parasito ocorre através de acaricidas químicos convencionais. Todavia, o uso indiscriminado desses produtos tem acelerado no processo de seleção de carrapatos resistentes às bases químicas disponíveis. Além disso, existe uma inquietude progressiva relacionada à segurança do meio ambiente e às saúdes humana e animal. Portanto, na busca de novas possibilidades de controle de carrapatos, o emprego de produtos fitoterápicos e biológicos mostra-se como alternativo promissor para o controle. Investigações com plantas para identificar novos princípios ativos capazes de controlar os carrapatos têm sido o foco de extensa pesquisa. Neste estudo, revisou-se o conhecimento atual disponível sobre óleos essenciais (OEs) testados no Brasil como acaricidas sobre R. microplus. Além disso, analisou-se a eficácia de compostos puros isolados dos OEs com potencial atividade acaricida, incluindo as implicações inerentes à aplicação dos OEs como ativos presentes em formulações que poderiam estar disponíveis no mercado. Contudo, considerou-se também a possibilidade de associações dos OEs a agentes utilizados no controle biológico. Palavras-chave: Carrapato dos Bovinos. Controle. Óleo essencial. Abstract In Brazil, the main species of tick that compromises productivity in cattle breeding is the hematophagous ectoparasite Rhipicephalus (Boophilus) microplus, with economic losses estimated at approximately 3.24 billion dollars annually. Such losses originate from the blood loss of the animal, from the fall in productivity, transmission of infectious agents, low efficiency of several of the tick products available on the market due to the phenomenon of resistance, among others. This tick is a vector of pathogenic agents that cause diseases that make up the tick-borne diseases complex. Generally, the control of this parasite occurs through conventional chemical acaricides. However, the indiscriminate use of these products has accelerated the process of selecting ticks resistant to the available chemical bases. In addition, there is a progressive concern regarding the safety of the environment and human and animal health. Therefore, in the search for new possibilities for the control of ticks, the use of herbal and biological products is promising alternatives for control. Investigations with plants to identify new active ingredients capable of controlling ticks have been the focus of extensive research. In this study, the current available knowledge about essential oils (EOs) tested in Brazil as acaricides on R. microplus was reviewed. In addition, the effectiveness of pure compounds isolated from EOs with potential acaricidal activity was analyzed, including the implications inherent to the application of EOs as active ingredients in formulations that could be available on the market. However, the possibility of associating EOs with agents used in biological control was also considered. Keywords: Cattle tick. Control. Essential oil.
