“…In the search for new methods to control these ectoparasites, medicinal plants emerge as a viable and promising alternative, due to the great variability of species, low cost and accessibility in particular regions (Agnolin et al, ). Over the last years, many essential oils and extracts of natural plants have showed promising effects to control R. microplus (Castro et al, ; Garcia et al, ; Singh and Chaturvedi, ).…”

The present study analyzed the effects of different concentrations of the hexane extract of A. oleraceae (HEAO) (Jambú) on the germ cells of semi-engorged Rhipicephalus microplus female ticks, through a morpho-histological study, evaluating the effectiveness of the extract in the genesis of the individuals. To perform this analysis, 100 semi-engorged females were divided into five groups with 20 individuals each: groups I and II, respectively constituted by distilled water control and 50% ethanol + 1% DMSO, and groups III, IV, and V constituted by treatment with HEAO in the concentrations of 12.5, 25.0 and 50.0 mg/mL, respectively. All the ticks were immersed in the different concentrations of the extract or in distilled water for 5 minutes, dried and conditioned in BOD incubator for 7 days. The individuals of the treatment groups revealed the action of this extract showing alterations in the germ cells of the females from the different groups when compared with those from the groups I and II (control groups). These alterations were mainly related to the size and shape of the oocytes; number of yolk granules; presence, number, size and location of vacuoles in the cytoplasm of all the germ cells; and the presence of nuclear alterations in these cells as well. Thus, it was demonstrated that the concentrations of HEAO affected the germ cells of R. microplus ticks. The effects of the extract are similar to those caused by renowned and efficient chemical products used to control these ticks. Microsc. Res. Tech. 79:744-753, 2016. © 2016 Wiley Periodicals, Inc.

“…In many countries, Brazil included, the acaricide-resistant tick population has been increasing, to the point that few acaricides have efficacy of more than 75% of the tick population (GRAF et al, 2004;MENDES et al, 2011). On the other hand, the results of certain studies suggest that environmentally friendly acaricides can be obtained from plants (GHOSH et al, 2011;GARCIA et al, 2012). As an alternative, plant extracts are used to manage animal health and parasite control in several regions in the world (GITHIORI et al, 2006;TAMIRU et al, 2013;NYAHANGARE et al, 2015).…”

The aim of this study was to assess the activity of aqueous (AE) and ethanolic extracts (EE) and pilocarpine hydrochloride, which were extracted and isolated from Pilocarpus microphyllus (Jaborandi), respectively, on Rhipicephalus (Boophilus) microplus. High performance liquid chromatography (HPLC) was performed to quantify these compounds. Larval packet and adult immersion tests were conducted with different concentrations. Five AE and EE concentrations, ranging from 6.2 to 100.0 mg mL–1, and six concentrations of pilocarpine hydrochloride, ranging from 0.7 to 24.0 mg mL–1, were tested. The lethal concentration (LC50) of each extract for larvae and engorged females was calculated through Probit analysis. The concentration of pilocarpine hydrochloride obtained from the EE and the AE was 1.3 and 0.3% (m/m), respectively. Pilocarpine hydrochloride presented the highest acaricidal activity on larvae (LC50 2.6 mg mL–1) and engorged females (LC50 11.8 mg mL–1) of R.(B.) microplus, followed by the EE which presented LC50 of 56.4 and 15.9 mg mL–1, for larvae and engorged females, respectively. Such results indicate that pilocarpine hydrochloride has acaricidal activity, and may be the primary compound responsible for this activity by P. microphyllus EE.

“…In the last decades, plant extracts were widely used against phytophagus pests and mosquitoes (Balandrin et al, 1995). The effect of neem extract on hard ticks was investigated by Rice, (1993), Magadum et al, 2009, BroglioMicheletti et al, (2010) and Garcia, (2012 and their results revealed a considerable efficacy against ticks.…”

“…This result is similar to results obtained by Kaaya and Saxena, (2000) who also found that feeding neem seed powder mixed with rabbit pellets (100:400 g) to goats daily for three weeks completely inhibited attachment and development of B. decoloratus larvae. Also with Garcia, (2012) who recorded 100% efficacy of commercial neem oil (Azadirachta indica) on A. miniatus larvae using the larval packet test (LPT). On contrast, Al-Rajhy et al (2003) concluded that azadirachtin showed some effects on larvae of camel tick, Hyalomma dromedarii.…”

Key words:Comparison, Butox ® , Diazinon, Achook, Acaricidal ActivityCommercially available preparations including Butox ® 50% (containing 5% deltamethrin), Diazinon 15% and Achook 0.15% (containing 0.15% Azadirachtin) were compared for their acaricidal activity against Rhipicephalus (Boophilus) annulatus engorged females obtained from naturally infested cattle from Rashid city, Behera Province, Egypt, and other developmental stages using immersion test. It was found that the highest mortality (86.6%) was achieved by using Diazinon 15% and Achook at concentrations of 4 ml/l and 0.15%, respectively. The complete inhibition of oviposition was observed when using Butox ® 50% and diazinon 15% at all used dilutions while Achook caused drop in reproductive index (RI) of tested females reached 75% at concentration of 0.075%. On the other hand, the bioassays on eggs and larvae revealed the superior effect of Achook over Butox ® 50% and Diazinon 15%; as the lowest hatchability (0%) of eggs and highest mortality (100%) within the first 24 hours post treatment on unfed larvae was achieved in Achook at both concentrations of 0.15% and 0.075% azadirachtin. Finally, it was concluded that Butox ® 50%, Diazinon 15% and Achook 0.15% commercially available pesticides showed variation in percentages of adult tick and larval mortalities, inhibition of oviposition and hatching of laid eggs. Promising results of Achook which is a product for agricultural use and does not have recommended dose for veterinary application yet needs further investigations to be recommended.
