“…Nas regiões Sudeste, Centro-Oeste e Nordeste do Brasil predomina o uso de aspersão com bombas costais, bem como a aplicação de um volume menor de inseticida/acaricida que o recomendado para o controle desses parasitos (Saueressig & Barros 2003, Rodrigues et al 2004, Rocha et al 2006, 2011b, Barros et al 2007, Mendes et al 2011. O mesmo método e problema de aplicação foram encontrados no presente estudo (Quadro 4) e, em última análise, contribuem para comprometer ainda mais a eϐicácia dos produtos utilizados.…”

“…De modo geral, os produtos inseticidas utilizados para o controle de H. irritans na região estudada (Quadro 5) coincidem com o observado em outros estados, onde predominam os piretróides e suas associações com os organofosforados (Saueressig & Barros 2003, Rodrigues et al 2004, Barros et al 2007). Segundo dados do Compêndio de Produtos Veterinários (2011), existem 95 produtos registrados para o controle da mosca-dos-chifres no Brasil, sendo 29 compostos por piretróides e 25 por associações entre piretróides e organofosforados.…”

“…O uso indiscriminado de tais produtos, juntamente com práticas inadequadas para o combate dos parasitos e a falta de especiϐicidade dos ectoparasiticidas, tem colaborado para a rápida seleção de populações resistentes (Santos Junior et al 2000, Saueressig & Barros 2003, Rodrigues et al 2004, Barros et al 2007, Santos et al 2009, Mendes et al 2011.…”

Pesq. Vet. Bras. 32(12):1246-1252, dezembro 2012 1246 RESUMO.-O controle eϐicaz de Haematobia irritans (mosca--dos-chifres) e Rhipicephalus (Boophilus) microplus (carrapato-do-boi) é um fator crucial à maior rentabilidade da pecuária brasileira, porém ainda constitui-se um desaϐio. Um maior conhecimento das práticas adotadas no combate destes parasitos faz-se necessário para que se possam estruturar estratégias de controle mais próximas da realidade do produtor rural e mais fáceis de serem executadas. The effective control of Haematobia irritans (horn ϐly) and Rhipicephalus (Boophilus) microplus (cattle tick) is crucial for increasing the productivity of livestock industry in Brazil, but still remains a challenge. A greater knowledge about parasite control in the ϐield is necessary to establish control strategies closer to farmer's reality and easier to be performed. This study characterized the practices adopted for controlling such ectoparasites on 23 cattle ranches from the Triângulo Mineiro and Alto Paranaíba region in the state of Minas Gerais, through interviews. Most interviewees recognized the importance of these parasites to livestock, however, many problems related to parasite control were observed. Control of horn ϐlies and cattle tick was a routine in 17.4% and 95.7% of the ranches, respectively, triggered by high infestations on animals. More than six insecticide/acaricide treatments were applied yearly in all cattle ranches controlling horn ϐlies and in 76.5% of the ranches controlling the cattle tick. Pesticide products were applied mostly by manual backpack sprayers (63.6%) without restraining the animals in 45.5% of ranches. Product dilution following manufacturer's recommendations was performed by 45.5% of interviewees, but 63.6% of them used lower doses per animal than technically recommended. Associations of organophosphates and pyrethroids were the main products used to control both parasites. Although pesticide use was a routine practice, the use of personal protective equipment (PPE) was not common among surveyed people. Most interviewees were able to recognize epidemiological characteristics of the parasites; however, parasite control measures adopted at most cattle ranches tend to jeopardize the efϐicacy of products, susceptibility of parasites and sustainability of control programs.

“…The current state of fly resistance in Brazil is due to more than a decade of chemical control, along with commercial dominance of pyrethroid-based products (BARROS et al, 2007).

The aim of this investigation was to evaluate the efficiency of partial treatment of animals infested with horn flies. Forty-five Guzerat cows between 4 and 7 years of age were divided into three groups (15 cows per group). The treatments were as follows: in groups G33 and G100, 33.3 and 100% of the cows were treated with one insecticide-impregnated ear tag/animal (40% diazinon), respectively, while in the group GC, the cows were not treated (control). The flies on the cervico-dorsal-lumbar region of the cows, in all three groups, were counted every 14 days. The experiment lasted from September 2006 to September 2009. Over this period, six four-month ear tag treatments, with intervals of one to two months, were conducted on both treated groups. The animals of group G33 had a higher infection than those of group G100, and the number of flies ranged from 12 to 27 (group G33) and from 3 to 11 (group G100). However, groups G33 and G100 had lower infection levels than group GC, which presented from 45 to 87 flies. Partial treatment of cattle infested with horn flies using 40% diazinon insecticide is an efficient alternative for controlling this ectoparasite.
