“…microplus specimens from the states of São Paulo, Ceará, Minas Gerais and on many properties in Mato Grosso do Sul (Tables 2 and 3), with these products exhibiting efficacy ranging from zero to 100% for the three analyzed active ingredients (alpha-cypermethrin, cypermethrin and deltamethrin). These results confirmed the results obtained by Koller et al (2009), Gomes et al (2011) and Mendes et al (2013) in Mato Grosso do Sul and those obtained by Mendes et al (2001Mendes et al ( , 2011 and Pereira (2006) in the state of São Paulo. There are no reports of such resistance in Ceará (HIGA et al, 2015), but it has been reported in other states in the northeastern region of Brazil, including Bahia (CAMPOS & OLIVEIRA, 2005;RAYNAL et al, 2013) and Pernambuco (SILVA et al, 2005).…”

“…microplus specimens from 6 of the 24 (25%) properties evaluated, with an average efficacy of 88.13%. These data confirmed the results of Koller et al (2009) and Gomes et al (2011), who also tested this product using the "Adult Immersion Test" and found unsatisfactory average efficacies of 85.64% and 85.28%, respectively.…”

“…According to Gomes et al (2011), in addition to reducing meat and milk production, the skin lesions caused by tick infestation affect leather prices and contribute to the development of myiasis. This ectoparasite has also been associated with the transmission of pathogens, such as Babesia bovis, B. bigemina and Anaplasma marginale (Bovine Babesiosis and Anaplasmosis Complex).…”

The Rhipicephalus (Boophilus) microplus tick is responsible for considerable economic losses in Brazil, causing leather damage, weight loss and reduced milk production in cattle and results in the transmission of pathogens. Currently, the main method for controlling this tick is using acaricides, but their indiscriminate use is one of the major causes of resistance dissemination. In this study, the adult immersion test (AIT) was used to evaluate resistance in ticks from 28 properties located in five different states (Mato Grosso do Sul, Mato Grosso, Ceará, São Paulo, e Minas Gerais) and the Distrito Federal (DF) of Brazil. The resistance was found in 47.64% of the repetitions demonstrating an efficacy of less than 90% in various locations throughout the country. The larvae packet test was used to evaluate samples from ten properties in four states (Mato Grosso do Sul, Mato Grosso, Minas Gerais and Espírito Santo). Spray products belonging to the main classes of acaricides, including combination formulations, were used in both types of test. New cases of resistance were found on properties within the states of Ceará, Espírito Santo and Mato Grosso, where such resistance was not previously reported.

“…However, the indiscriminate use of these substances has been conducted to the appearance of several cases of tick resistance (Arantes et al, 1995). This phenomenon has been widely reported (Li et al, 2004;Rosado-Aguilar et al, 2008), including various descriptions in Brazil (Campos Júnior;Oliveira, 2005;Gomes et al, 2011), where there are reports in Rio Grande do Sul (Patarroyo;Costa, 1980), Minas Gerais, Espírito Santo (Leite et al, 1995), São Paulo (Soares et al, 2001), Bahia and Pernambuco (Santana et al, 2013).…”

Evaluation of the efficacy of cypermethrin and amitraz against Rhipicephalus (Boophilus) microplus, in the State of Pernambuco, Brazil

et al. 2016

The Rhipicephalus (Boophilus )microplus is an important tick species which affect bovines in tropical areas. Its control is based on the use of chemical acaricides, but the frequent use of these substances has been conducted to the development of tick resistance. The aim of this study was to assess the efficacy of cypermethrin and amitraz against R. (B. )microplus collected of bovines from different municipalities of the state of Pernambuco. From August 2009 to July 2011, engorged females were collected and subjected to the "Adult Immersion Test" in order to evaluate the efficacy of cypermethrin and amitraz. The results indicate that populations of R. (B. )microplus from Pernambuco present resistance to acaricides (i.e., cypermethrin and amitraz). In this study, a single population (Brejo da Madre de Deus) was susceptible to cypermethrin, whereas two (Timbaúba and Limoeiro) were susceptible to amitraz. Data herein reported follow a pattern observed in other regions of Brazil and alert to the fact that alternative measures of control should be implemented in this area studied.

“…(B.) microplus to almost every chemical group in Mato Grosso do Sul State has been demonstrated; this situation is detrimental to Brazil as a whole (GOMES et al, 2011) and affects several other countries (FAO, 2004). Due to this reduction in the susceptibility to current acaricidals, there has been an increase in the development of studies using natural products to search for new active ingredients (NEEWMAN;CRAGG, 2012).…”

This research evaluated the in vitro acaricidal activity of extracts from 21 plant species from the Pantanal of Mato Grosso do Sul. During stage I, a larval immersion test was performed using three extract concentrations (5%, 20%, and 40%). During stage II, we used only plants that showed over 95% efficiency at the 40% concentration in stage I in an amount sufficient for the adult immersion test. Aeschynomene denticulata, Angelonia hirta, Aspilia latissima, Caperonia castaneifolia, Centratherum punctatum, Crotalaria micans, Diodia kuntzei, Echinodorus paniculatus, Hyptis mutabilis, Lantana canescens, Melanthera latifolia, Ocotea diospyrifolia, Richardia grandiflora, Sebastiana hispida, Tocoyena formosa, Zanthoxylum rigidum, and Sesbania virgata (fruit extract) showed acaricidal activity against the larval stage of Rhipicephalus (Boophilus) microplus higher than 95% at a 40% (w/v) concentration, while Hippocratea volubilis and Randia armata showed moderate efficacy and Croton glandulosus and Senna obtusifolia had no effect. The M. latifolia, A. hirta, R. grandiflora, and A. latissima raw extracts were evaluated for their activity against adults, and only A. hirta showed an efficacy close to 90%. Eighteen extracts had an efficacy of up to 95% against larvae at a 40% concentration, seven extracts were effective at 20%, and only one (Sebastiana hispida) was effective at a 5% concentration.Keywords: Cattle tick, natural compounds, phytotherapy, parasites.

Os extratos brutos de M. latifolia, A. hirta, R. grandiflora e A. latissima foram avaliados sobre adultos e A. hirta apresentou eficácia próxima de 90%. Dezoito extratos apresentaram eficácia de até 95%, contra larvas, na concentração de 40%, sete extratos foram eficazes a 20% e apenas um (Sebastiana hispida) foi eficaz na concentração de 5%.Palavras-chave: Carrapato bovino, compostos naturais, fitoterapia, parasitas.
