Acaricidal activity of leaves of Morus nigra against the cattle tick Rhipicephalus microplus Arq. Bras. Med. Vet. Zootec.
Dantas,A.C.S.; Freire,D.P.; Souza,G.R.; Almeida,J.R.G.S.; Rolim,L.A.; Castro,R.N.; Horta,M.C..
ABSTRACT The acaricidal activity of crude ethanolic extract and fractions from the leaves of Morus nigra (Moraceae) was carried out on female cattle ticks Rhipicephalus microplus, using the adult immersion test. The mortality and fertility of females exposed to different concentrations of hexane, chloroform and ethyl acetate fractions, as well as ethanolic extract of M. nigra with concentrations of 5, 10 and 25mg/ml were evaluated using three treatment groups, two control groups and triplicate tests. The study also identified the main phenolic compounds of the extract and fractions of this species by HPLC. The chloroform fraction of leaves of M. nigra (25mg/mL) showed the best results for this species, obtaining 62.6% of inhibition of oviposition, 39.3% of...

Acaricide activity of leaves extracts of Sambucus australis Schltdl. (Caprifoliaceae) at 2% on engorged females of Rhipicephalus (Boophilus) microplus Ciência Rural
Krawczak,Felipe da Silva; Buzatti,Andréia; Pivoto,Felipe Lamberti; Sangioni,Luís Antônio; Vogel,Fernanda Silveira Flores; Botton,Sônia de Avila; Zanetti,Gilberto Dolejal; Manfron,Melânia Palermo.
Parasite infections caused by Rhipicephalus (Boophilus) microplus are responsible for the most of economic losses in producing-cattle countries in tropical and subtropical areas. Indiscriminate uses of chemical acaricides have contributed with the appearance of tick resistance to many drugs available in the marketplace, and it is a serious problem in the tick control. Flowers of Sambucus australis (South America), called "sabugueiro-from-Brazil", are used on infusions or decoctions forms in the folk medicine with diuretic, antipyretic, anti-inflammatory, and laxative purpose, also employed for treating respiratory diseases in human. The main goal of this study was to evaluate in vitro potential of S. australis leaves extracts as an acaricide agent. Ethanol...

APPLICATION OF TICK SAMPLING ON ACARICIDAL BATH FREQUENCY IN Rhipicephalus (Boophilus) microplus (ACARI: IXODIDAE) Rev Salud Anim.
de la Vega,R; Díaz,G; Camejo,A; García,I.
In this paper, a tick sampling method developed by authors was employed with the purpose of saving acaricides and decreasing environmental pollution by the use of acaricidal dip control bathing bovines in relation to a critical number of estimated ticks. Twenty-six Jersey cows in production were sampled. The selected sampling regions were: rear leg, udder, perinea and tail. Samplings were done from 7 to 8 am, and female tick standard size pattern was 6 mm or longer. Every two weeks approximately, samplings and acaricidal baths were done (13 samplings in total). Only cows with 10 or more ticks received acaricidal baths. Results showed that the procedure allows saving 50% of acaricides.

Effect of oral exposure to the acaricide pirimicarb, a new varroacide candidate, on apis mellifera feeding rate ArchiMer
Riva, Clemence; Sokolowski, Michel B. C.; Normand, Julien; Santos, Jana Sopkova-de Oliveira; Halm-lemeille, Marie-pierre.
BACKGROUND The ectoparasitic honey bee mite Varroa destructor is one of the main causes related to the gradual decline of honey bees Apis mellifera. Nowadays, beekeepers utilize a wide range of different synthetic acaricides, organic acids and essential oils to keep mite populations under control. A previous work had shown that pirimicarb could be a new varroacide candidate. The aim of this study was to observe the chronic effects on worker honey bees feeding activity after an oral exposure to 1.05 mM of pirimicarb. Long-term effect of a 24 hours exposition to pirimicarb were also tested. RESULTS After three successive trials were performed, no mortality could be detected at the tested concentration, oral exposure to pirimicarb had significant effect on...

Emergence of multi-acaricide resistant Rhipicephalus ticks and its implication on chemical tick control in Uganda OAK
Vudriko, Patric; Okwee-Acai, James; Tayebwa, Dickson Stuart; Byaruhanga, Joseph; Kakooza, Steven; Wampande, Edward; Omara, Robert; Muhindo, Jeanne Bukeka; Tweyongyere, Robert; Owiny, David Okello; Hatta, Takeshi; Tsuji, Naotoshi; Umemiya-Shirafuji, Rika; Xuan, Xuenan; Kanameda, Masaharu; Fujisaki, Kozo; Suzuki, Hiroshi.
Background: Acaricide failure has been on the rise in the western and central cattle corridor of Uganda. In this study, we identified the tick species associated with acaricide failure and determined their susceptibility to various acaricide molecules used for tick control in Uganda. Methods: In this cross sectional study, tick samples were collected and identified to species level from 54 purposively selected farms (from 17 districts) that mostly had a history of acaricide failure. Larval packet test was used to screen 31 tick populations from 30 farms for susceptibility at discriminating dose (DD) and 2 x DD of five panels of commercial acaricide molecules belonging to the following classes; amidine, synthetic pyrethroid (SP), organophosphate (OP) and...

In vitro effects of Pilocarpus microphyllus extracts and pilocarpine hydrochloride on Rhipicephalus (Boophilus) microplus. Repositório Alice
CASTRO, K. N. de C.; LIMA, D. F.; WOLSCHICK, D.; ANDRADE, I. M. de; SANTOS, R. C. dos; SANTOS, F. J. de S.; VERAS, L. M. C.; COSTA-JÚNIOR, L. M..
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...

In vitro evaluation of the effects of some acaricides on life stages of Rhipicephalus sanguineus (Acari: Ixodidae) Arq. Bras. Med. Vet. Zootec.
Bicalho,K.A.; Ferreira,F.; Borges,L.M.F.; Ribeiro,M.F.B..
The action of five acaricides was evaluated on eggs, larvae, nymphs and adults of the ixodid tick Rhipicephalus sanguineus. The acaricides tested were: high cis-cypermethrin (0.01%) + DDVP (0.11%), coumaphos (0.05%), deltamethrin (0.0025%), amitraz (0.025%) and cypermethrin (0.015%). Eggs treated with high cis-cypermethrin and cypermethrin showed eclosion inhibitions of 72.1% and 67.3%, respectively, whereas coumaphos was much less effective (only 11.7%). Except for coumaphos, which resulted in 63.3% and 80.0% mortality of nymphs and unfed females, respectively, all compounds tested killed 100% of all tick stages to which they were exposed.
