“…Therefore, follow-up studies are needed to validate this strategy. The advantage of using plant extracts may be slow resistance development because the extracts are usually composed of a mixture of different active agents with different mechanisms of action (OLIVO et al, 2009).…”

“…Studies conducted by Olivo et al (2009) evaluated the action of four increasing concentrations (1.25 to 5%) of an aqueous extract of Nicotiana tabacum on naturally infested animals. The efficacies ranged from 62% at a concentration of 5% in the first week up to 77.5%, 14 days after treatment, at the lowest concentration.…”

“…One advantage from the use of those compounds is that resistance develops slowly because there is usually a mixture of different active agents with different mechanisms of action (BALANDRIN et al, 1985;CHAGAS et al 2003;OLIVO et al, 2009). Plant based formulations enable expansion of organic agriculture or may even be used as an auxiliary in conventional production systems (VIEIRA;CAVALCANTE, 1999;OLIVO et al, 2009).…”

“…Aproximadamente 55 espécies de plantas já foram testadas contra o R. microplus, incluindo Nicotiana tabacum L. (Solanales: Solanaceae) (Borges, Sousa, Barbosa, 2011). O efeito carrapaticida de N. tabacum sobre R. microplus já foi verificado predominantemente sobre fêmeas (Olivo et al, 2009;Rodríguez, Rodríguez, Cruz, 2010;Leal et al, 2014). Porém são necessários mais estudos, voltados principalmente para as diferentes formas de obtenção e aplicação dos extratos dessa planta (Olivo et al, 2009).…”
