“…The effect against engorged females was low (19.2%) at the highest concentration of the hexanic extract, but on other hand, it killed all larvae in all concentrations (RIBEIRO et al, 2007). Similar effects were observed with the hexanic extracts of stems and leaves of Calea serrata (Asteraceae) at the same concentrations (RIBEIRO et al, 2008a).…”

The evolution of resistance of Rhipicephalus (Boophilus) microplus to synthetic acaricides has given rise to the need for new scientific investigations on alternative ways to control this tick. In this regard, various studies on plants have been developed in an attempt to find extracts with acaricidal properties. Evaluations on plant extracts for controlling R. (B.) microplus have grown intensely over the last decade. There are many advantages from using plant extracts: for example, they can be used in organic cattle farming or even replace synthetic acaricides and they are associated with lower environmental and food contamination, slower development of resistance and lower toxicity to animals and humans. In vitro studies on plant extracts have shown promising results, but most of these extracts have not been tested on animals to validate their use. Difficulties in preparing proper formulations, differences in the chemical composition of plants of the same species due to extrinsic and intrinsic factors and sparse information on active acaricide compounds are hindrances that need to be addressed in order to enable progress within this scientific field.Keywords: Phytotherapy, cattle tick, Rhipicephalus (Boophilus) microplus, in vitro bioassays, in vivo bioassays. ResumoA evolução da resistência do Rhipicephalus (Boophilus) microplus aos acaricidas sintéticos tem impulsionado novas investigações científicas sobre métodos alternativos para controlar este carrapato. Considerando isso, vários estudos com plantas têm sido desenvolvidos numa tentativa de encontrar extratos com propriedades acaricidas. Avalições de extratos de plantas para o controle de R. (B.) microplus tem sido intensificadas nesta última década. Existem muitas vantagens com o uso de extratos de plantas no controle deste carrapato, como: eles podem ser utilizados na produção orgânica de bovinos, ou mesmo substituir os acaricidas sintéticos, além do mais, estão associados com baixa contaminação ambiental e dos alimentos, desenvolvimento mais lento de resistência e baixa toxicidade para animais e seres humanos. Estudos in vitro de extratos de plantas têm apresentado resultados promissores, mas a maioria destes extratos não têm sido testada em animais para validar estes resultados. Dificuldades para preparar formulações apropriadas, diferenças na composição química de plantas de uma mesma espécie devido a fatores intrínsecos e extrínsecos e informações esparsas.sobre os princípios ativos são entraves que precisam ser solucionados visando o desenvolvimento deste campo de pesquisa.Palavras-chave: Fitoterapia, carrapato de bovinos, Rhipicephalus (Boophilus) microplus, testes in vitro, testes in vivo.

“…The average weight of engorging ticks was 0.3 g. These females were incubated at 27-28 o C and 70-80% relative humidity for two weeks until the egg laying. These eggs provided the larvae used for the larval immersion test -LIT (Ribeiro et al 2007). The LIT was conducted by placing approximately 100 embryonated eggs (0.005 g) into pockets (1.0 cm x 1.5 cm) made with TNT fabric.…”

Among them, essential oils components are known to possess repellent, chemosterilant, antifeeding and biocidal activities against different acarus, showing promissory potential as products for tick control, since some of them are selective and have little or no harmful effects on non-target organisms (Facey et al 2005;Panella et al 2005;Dietrich et al 2006;Tunon et al 2006;Apel et al 2009).…”

“…O aumento do número de cepas de carrapatos resistentes aos acaricidas químicos realça a necessidade de se buscar métodos alternativos de controle do carrapato e os compostos bioativos naturais são uma alternativa promissora para esse controle (RibeiRo et al, 2007;FeRnandes;FReitas, 2007). Em todo o mundo, extratos de aproximadamente 55 espécies de plantas pertencentes a 26 famílias já foram avaliados contra Rhipicephalus (Boophilus) microplus (boRges et al, 2011).…”

Eficácia in vitro de extratos de Chenopodium ambrosioides sobre teleóginas de Rhipicephalus (Boophilus) microplus

RESUMOChenopodium ambrosioides L. (Amaranthaceae) (erva-de-santa-maria) é uma planta fortemente aromática usada popularmente por suas propriedades antiparasitárias. Avaliou-se com este estudo a eficácia in vitro de extratos hidroetanólicos de C. ambrosioides sobre a postura e a eclodibilidade larval de Rhipicephalus (Boophilus) microplus (Canestrini, 1888) (Acari: Ixodidae), usando o teste de imersão de fêmeas ingurgitadas adultas. Os tratamentos foram constituídos por extratos feitos com 5%, 10% e 25% de C. ambrosioides (massa/volume), água destilada e veículo (constituído de propilenoglicol a 5%, etanol a 25% e água destilada). Dez teleóginas foram distribuídas de forma homogênea para cada grupo e imersas por 5 minutos em cada um dos extratos testados. Os extratos feitos com 5%, 10% e 25% de C. ambrosioides apresentaram eficácias médias de 13,27%, 22,56% e 31,87%, respectivamente. Estes resultados indicam que, nas concentrações usadas, os extratos de C. ambrosioides não apresentam potencial para o controle das cepas pesquisadas de R. (B.) microplus.PALAVRAS-CHAVE: Erva-de-santa-maria, acaricida, fitoterapia, controle do carrapato bovino. ABSTRACT IN VITRO EFFICACY OF CHENOPODIUM AMBROSIOIDES EXTRACTS ON RHIPICEPHALUS (BOOPHILUS) MICROPLUS ENGORGED FEMALES. Chenopodium ambrosioides L. (Amaranthaceae)(wormseed) is a strongly aromatic plant employed popularly for its antiparasitic properties. This study evaluated the in vitro efficacy on laying and hatchability of eggs of Rhipicephalus (Boophilus) microplus (Canestrini, 1888) (Acari: Ixodidae) of hydroethanolic extracts from C. ambrosioides, using the adult immersion test. The treatments consisted of hydroethanolic extracts made with 5%, 10% and 25% of C. ambrosioides (weight/volume), distilled water and vehicle solution (consisting of propylene glycol at 5%, ethanol at 25% and distilled water). Ten ticks were distributed evenly for each group and immersed for 5 minutes in each of the tested extracts. The extracts containing 5%, 10% and 25% of C. ambrosioides showed average efficacies 13.27%, 22.56% and 31.87% respectively. These results indicate that extracts of C. ambrosioides, at the concentrations used, do not present potential for the control of the R. (B.) microplus strains researched.
