Haematobia irritans é uma mosca de grande importância na pecuária bovina. É responsável por causar estresse crônico ao rebanho causando desconforto e levando a redução da produção de carne e leite e depreciação do couro. Também são responsáveis por transmitir vírus, bactéria e facilitar ao desenvolvimento de míiases. O objetivo deste trabalho foi avaliar a eficácia de um produto ectoparasiticida contendo a associação de cipermetrina, clorpirifós, butóxido de pireronila e fluazuron na formulação "pour on" no controle da mosca H. irritans em bovinos naturalmente infestados. Foram utilizados 30 bovinos, mestiços, sem distinção de sexo ou idade. Todos os animais incluídos no estudo apresentaram pelo menos 50 moscas adultas de H. irritans de ocorrência natural. Os animais do grupo tratado foram medicados com a associação de cipermetrina (5 mg/kg), clorpirifós (7 mg/kg), butóxido de pireronila (5 mg/kg) e fluazuron (2,5 mg/kg), na dose de 1 mL para cada 10 quilos de peso vivo, pela via tópica ("pour on") em dose única. A eficácia mosquicida foi avaliada um, três, sete, 14 e 21 dias após o tratamento, a partir da contagem de moscas adultas sobre os animais dos dois os grupos. A eficácia da associação testada neste estudo foi de 98,65%; 96,69%; 92,01%; 87,79% e 76,43% nos dias +1, +3, +7, +14 e +21 respectivamente. A associação de cipermetrina, clorpirifós, butóxido de piperonila e fluazuron na formulação "pour on" é eficaz no controle de H. irritans em bovinos naturalmente infestados.Palavras-chave: controle, mosca do chifre, piretróide, organofosforado. AbstractHaematobia irritans is a fly of great importance in cattle breeding. It is responsible for causing chronic stress due to discomfort and leading to reduced meat and milk production and depreciation of leather. They are also responsible for transmitting viruses, bacteria and facilitating the development of myiasis. The objective of this study was to evaluate the efficacy of a product ectoparasiticide containing a association of cypermethrin, chlorpyrifos, butoxide pireronila and fluazuron in formulating "pour on" the fly control H. irritans in cattle naturally infested. Were used thirty crossbred cattle, regardless of sex or age. All animals included in the study had at least 50 naturally occurring adult H. irritans flies. The animals in the treated group were medicated with the combination of cypermethrin (5 mg/kg), chlorpyrifos (7 mg/kg), pireronyl butoxide (5 mg/kg) and fluazuron (2.5 mg/kg) at a dose of 1 mL for every 10 kg live weight, "pour on" in single-dose. Efficacy was evaluated one, three, seven, 14 and 21 days after treatment, from the adult flies count on the animals of the two groups. The efficacy of the association tested in this study was 98.65%; 96.69%;...

“…Atualmente já existem relatos de H. irritans resistentes a estes quatros princípios ativos citados anteriormente. Portanto a busca de novas moléculas ou associações são necessárias para o controle desta mosca (Sparks et al, 1985;Oyarzún et al, 2008;Stafford & Coles, 2017).…”

“…Cattle are continuously annoyed by the feeding activity of horn flies (Oyarzún et al 2008). Foil and Hogsette (1994) described that both male and female H. irritans spend their entire life on the host, feeding 24-38 times/day, using their piercing sucking proboscis.…”

“…An insect can consume between 11 to 21 mg blood/day, and an animal infected with 500 flies can potentially lose up to 7 ml blood/day (Cupp et al 1998;Tommasi, 1999). The economic impact of horn fly biting on weight gain in beef cattle and milk production has been reviewed by Oyarzún et al (2008). An infestation between 200 and 400 flies per animal can cause a 4-20% decrease in weight gain and 4-12% decrease in milk production (Guglielmone et al 1998;DeRouen et al 2003).…”

Background: The horn fly, Haematobia irritans, is an obligate bloodsucking ectoparasite of pastured cattle and is a major pest of livestock production in North and South America and Europe. In this study, we investigated the potential to use cattle pastures, infected with non-toxic, "friendly" fungal-endophyteinfected (E+) tall fescue, Festuca arundinacea Schreb., as a strategy for reducing horn fly loads in cattle, and to evaluate the possible bioinsecticide effect on horn fly larvae. Results: When cattle grazed in E+ tall fescue, a decrease in fly-load was observed, compared with other pastures (endophyte-free (E-) pastures). The infestation of horn fly load decreased according to an increase in the percentage of endophyte present in the different pastures (0 to 100%). Moreover, two groups of animals with significant differences in the fly-load (high and low fly-load) in the same herd were observed (P < 0.05). Additionally, it was possible to determine a bioinsecticide effect of cattle dung, upon horn fly larvae (80%), from animals fed E+ tall fescue. Conclusions: These results constitute the first report on the potential for exploiting pasture management for controlling 1) horn fly-loads on cattle and 2) the normal development of horn fly larvae. In conclusion, this information provides preliminary understanding of the role of cattle pasture diet management for controlling horn fliesas part of an integrated pest management strategy for this major pest of farmed livestock.

“…These flies' painful biting causes milk and meat production losses and affects leather marketing as well (GARCÍA et al, 2001;SCOTT et al, 2002). The resulting economic losses have intensified the use of insecticides to control horn fly infestation on cattle (MARTINS et al, 2002;SCOTT et al, 2002;OYARZÚN, et al, 2008). However, misuse or excessive use of insecticide products has selected flies for resistance to the active ingredients used (BARROS, 2004;OLIVEIRA et al, 2006;OYARZÚN, et al, 2008).…”

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.
