The efficiency of extracts of Dahlstedtia pentaphylla (Leguminosae, Papilionoidae, Millettiedae) on Boophilus microplus (Canestrini, 1887) in artificially infested bovines

Perspectives for the use of plant extracts to control the cattle tick Rhipicephalus (Boophilus) microplus

“…Similar results were observed by Magadum et al (2009), also using neem seeds at the same concentration as Srivastava et al (2008). Pereira and Famadas (2006) tested the root extract of D. pentaphylla at concentrations of 1:10 and 1:20 mL, on artificially infested bovines. The highest efficacies were observed on the third and seventh days after treatment, reaching 76% in the group treated with the lowest concentration.…”

“…The main compounds found in these plants were α-pinene, β-pinene, sabinene, menthofuran and 1,8-cineole (APEL et al, 2009). Pereira and Famadas (2004) evaluated the action of the ethanolic root extract of Dahlstedtia pentaphylla (Leguminosae) against two strains of tick: one acaricide-sensitive Mozo strain, and one from the field. The plant was less efficient against the field strain.…”

Efficiency of the latex from Euphorbia splendens var. hislopii (N.E. Br.) Ursch & Leandri, Euphorbiaceae, in the control of Rhipicephalus (Boophilus) sanguineus (Latreille, 1806) (Acari: Ixodidae)

“…As from day 21 the latex became less effective for all treatments, and by day 28 the product already had no effect whatsoever. These results suggest a better effect of the latex against engorged larvae, this because according to Pereira & Famadas (2004), scientific studies have proved that the larval stage of Boophilus microplus (Canestrini, 1887) is about eight times as sensitive to the product as the adult stage. In another study, Pereira & Famadas (2006) observed that the efficiencacy of Dahlstedtia pentaphylla (Leguminosae, Papilionoidae, Millettiedae) at in the concentrations of (1:10 and 1:20 mL) persisted up to day 7, and as from day 14, the product became less effective.…”

“…On the first 1 day after treatment the effect of product proved to be was very small or negligible in the treated groups treated with 25 µL/L (4), 125 µL/L (3.33) and 250 µL/L (1.66). Pereira & Famadas (2004), observed mortality of engorged females of Boophhilus microplus (Canestrini, 1887) subjected to treatment with root extract from Dahlstedtia pentaphylla (Leguminosa, Papilionoidae, Millettiedae), which only becomes evident as from second day of exposure to the product. In the present study the best result obtained was seen 1 and 3 days after the application of the extract at a concentration of 100 µL/L (9.66 and 8.66) and 500 µL/L (5.66 and 9.33) respectively when compare to the control group.…”

Comparative in vitro anti-tick efficacy of commercially available products and newly developed phyto-formulations against field collected and resistant tick lines of Rhipicephalus (Boophilus) microplus

“…Extensive work has been done on plant based natural products having acaricidal activities against many species of ticks (Borges et al 2003;Pereira and Famadas 2006;Fernandes and Freitas 2007;Kamaraj et al 2010;de Souza Chagas et al 2012;Juliet et al 2012;Sunil et al 2013) including acaricide resistant species as the natural products can delay the development of resistance due to the presence of a number of active molecules having different mode of action (Wang et al 2007).…”
