“…microplus larvae. Extracts of O. diospyrifolia, for example, produced mortality above 95% in the larval immersion test (LIT) at 40% concentration (Santos et al, 2013). O. aciphylla also had efficacy higher than 90% in the LPT at 50 mg/mL (Conceição et al, 2017).…”

Rhipicephalus (Boophilus) microplus is responsible for reducing animal welfare, causing a drop in productive performance and transmitting hemoparasites. The main strategy of tick control is application of synthetic acaricides. However, parasite resistance to these compounds is a major concern. Therefore, the acaricidal and repellent in vitro effect of the Ocotea elegans essential oil on larvae and adult females of R. (B.) microplus were evaluated. The larval packet test (LPT), larval repellency test (RT) and adult immersion test (AIT) were performed. The essential oil was analyzed by gas chromatography (GC/FID) and the structure of the oil's major constituent (92.2% sesquirosefuran) was elucidated by nuclear magnetic resonance. In the AIT, efficacy higher than 90% was detected from the concentration 25 mg/mL upward. In both LPTs performed after 48 h, only the 100 mg/mL concentration resulted in mortalities above 70%. On the other hand, the essential oil caused an average of 95.8% repellency from 0.78 to 100 mg/mL. The LC in the two LPT (48 h) tests were 59.68 and 25.59 mg/mL, respectively. The LC and LC in the AIT were 4.96 and 17.37 mg/mL, and in the RT they were 0.04 and 1.24 mg/mL respectively. We conclude that the essential oil of O. elegans leaves has a significant acaricidal effect on engorged females and on larval repellency of R. (B.) microplus ticks, and can be a promising alternative for the control of this ectoparasite.

“…(B.) microplus engorged females and larvae (Barbosa et al 2013;Santos et al, 2013). Likewise, Conceição et al (2017) evaluated hexane, ethyl acetate and ethanol extracts of Ocotea acidophyla leaves and all of them demonstrated acaricidal activity against different stages of the cattle tick.…”

“…However, in Pakistan, only a handful number of plants have been used against R. microplus (Zaman et al, 2012a;Sindhu et al, 2012;Nawaz et al, 2015) in contrast to more extensive investigations elsewhere (Chen et al, 2011;dos Santos et al, 2013;Nyahangare et al, 2015;Fouche et al, 2016a,b (Chagas et al, 2016;Vudriko et al, 2016). Briefly, larvae were inserted into drug impregnated filter paper for 24 hrs at certain temperature (27-29°C) and relative humidity (80-85%).…”

Geo-climatic and socio-economic conditions provide a favourable environment for parasitic population of livestock in Pakistan. Hard ticks (Ixodidae) and gastrointestinal nematodes pose most serious threats to livestock industry. Stackholders rely on synthetic drugs to control these parasites. Emergence of drug resistance in these parasites; however, has provoked interest in alternate of synthetic drugs. Testing of plants used in ethnoveterinary medicine for their antiparasitic activity employing standard procedures has been reported to be promising. Plants have been most frequently used for deworming purposes followed by as acaricides and insecticides; whereas, reports as to their antiprotozoal use are relatively less. Use of plants as antiparasitics is more frequent in developing countries having low accessability to the modern parasite control practices. Likewise, validation studies on the use of plants as antiparasitics have been more frequently carried out in the developing countries compared with those having livestock farming as commercial enterprise. This article presents an overview of the plants having acaricidal and anthelmintic activity, limitations as to the application of phytotherpay to control parasites and future prospects of the use of plants as antiparasitics.

The objective of this study was to identify the main chemical components of the essential oil of Cuminum cyminum L. (cumin) and of the fixed oils of Bertholletia excelsa (Brazil nut) and of Helianthus annuus (sunflower seed). As well as testing the three oils and three different commercial synthetic acaricides against engorged females of Rhipicephalus (Boophilus) microplus in order to explore their acaricidal efficacy. Six different concentrations of the oils (200, 100, 50, 25, 12.5 and 6.25 mg/mL) and the active principles were evaluated with the Adult Immersion Test (AIT). The two main chemicals components of C. cyminum L. were the cuminaldehyde and the γ-terpinene. In both B. excelsa and H. annuus were the linoleic and oleic acid. C. cyminum L. showed high acaricidal activity (100%) over the engorged females and on their reproductive characteristat from the concentration of 100 mg/mL. B. excelsa and H. annuus had low acaricidal activity (39.39% and 58.75% in the concentration of 200 mg/mL respectively). The amidine and the pyrethroid (35.12% and 1.50% respectively). It can be concluded that the oil of C. cyminum L. may be a phytoterapic alternative for the cattle's tick control.
