The Rhipicephalus (Boophilus) microplus tick is responsible for considerable economic losses in Brazil, causing leather damage, weight loss and reduced milk production cattle results the transmission of pathogens. Currently, main method controlling this using acaricides, but their indiscriminate use one major causes resistance dissemination. In study, adult immersion test (AIT) was used to evaluate ticks from 28 properties located five different states (Mato Grosso do Sul, Mato Grosso,...
O carrapato bovino, Rhipicephalus (Boophilus) microplus, destaca-se dentre os ectoparasitas de importância econômica à pecuária nacional, tornando-se necessária a adoção medidas controle, particularmente em rebanhos Bos taurus e seus cruzamentos. controle do tem sido cada vez mais difícil devido constatação populações resistentes aos diversos produtos uso. Neste estudo, teve-se por objetivo conhecer suscetibilidade desse acaricidas Mato Grosso Sul. De outubro 2003 2006, testes...
Coprophagous beetles were collected from a pasture area using pitfall traps baited with cattle fresh manure, February to December, 1995.Twenty three species collected, comprising the following genera: Digitonthophagus, Onthophagus, Dichotomius, Ontherus, Canthon, Canthidium, Ataenius, Aphodius, Pedaridium, Ateuchus, Trichillum, Coprophanaeus, and Megathopomina.Among Digitonthophagus gazella (Onthophagus gazella) was most numerous, followed in decreasing order by Ontherus appendiculatus,...
Since horn fly populations became established throughout Brazil, complaints regarding control failure have increased around the country. A broad survey to evaluate susceptibility of flies both organophosphate (OP) and pyrethroid insecticides was conducted from October 2000 April 2003. Bioassays using filter papers impregnated with cypermethrin, permethrin or diazinon were on 154 in 14 states 78 municipalities. Resistance active ingredient present most insecticide products for detected 98.46%...
Cochliomyia macellaria (Diptera: Calliphoridae), known as the secondary screwworm, occurs in Americas and has medical-veterinary forensic importance. This study aimed to describe seasonal fluctuation of this species Pantanal region, Central-Western Brazil. From December 2004 November 2007 fly catches using four windoriented traps baited with decaying bovine liver were carried out at Nhumirim ranch, Nhecolândia subregion, Southern Pantanal. Traps remained active throughout period collections...
A mosca-dos-chifres (Haematobia irritans) é um dos principais ectoparasitos de bovinos no Brasil. Estudos epidemiológicos são exigidos devido às dificuldades crescentes do seu controle químico. Por isso, para melhor conhecimento da dinâmica populacional sazonal desta mosca foram realizadas contagens a cada 14 dias sobre corte, entre 7 e 30 meses idade, durante o período inverno 1996 até verão 2002. Foi verificada elevação nos níveis populacionais H. irritans (P<0,05), as estações...
A expansão da indústria sucroalcooleira tem levado à instalação de usinas álcool em áreas tradicionalmente ocupadas pela pecuária corte na região Centro-Oeste do País. Surtos mosca-dos-estábulos (Stomoxys calcitrans) bovinos Nelore têm sido relatados nos últimos dois anos Mato Grosso Sul, associados a estas usinas. Visitas propriedades pecuárias e foram realizadas meados novembro 2009, ao final surtos por S. calcitrans ocorridos municípios Angélica Ponta Porã, MS. Entrevistas, observações...
Horn fly susceptibility to insecticides was evaluated in the state of Mato Grosso do Sul, Brazil, from October 2000 September 2002. Insecticide bioassays (n=57) were conducted 38 ranches 14 municipalities throughout state. flies wild populations collected on cattle and exposed filter papers impregnated with cypermethrin, permethrin, or diazinon mortality assessed after two hours. Resistance cypermethrin detected all populations, resistance ratios (RR) ranging 27.6 91.3-fold. Permethrin...
Em 1989, o besouro Onthophagus gazella Fabr. foi importado dos Estados Unidos, para compor programa de controle integrado helmintos e da mosca-dos-chifres, Haematobia irritans L. Por não se ter conhecimento que os piretróides ou seus resíduos, quando eliminados pelas fezes, poderiam estar afetando africano, testaram-se alguns inseticidas "pour-on" vêm sendo utilizados no combate à mosca-dos-chifres. Quinze animais machos, Nelore com cerca 24 meses idade, foram distribuídos, aleatoriamente,...
Massas fecais semi-frescas a quase secas foram coletadas semanalmente, em uma pastagem de Brachiaria decumbens Stapf, maio 1990 abril 1992. Estas fezes colocadas baldes plásticos opacos (15 l), apresentando saída lateral e outra no topo, contendo frascos para coleta dos besouros coprófagos adultos presentes nas massas. Foram coletados 18.844 exemplares da família Scarabaeidae, pertencentes 37 espécies, seguintes gêneros: Ataenius, Aphodius, Agamopus, Pedaridium, Trichillum, Eurysternus,...
Species of the genus Chrysomya Robineau-Desvoidy 1830 (Diptera: Calliphoridae) play an important role in public health due to myiasis and transmission enteropathogens.This study aimed estimate relative abundance seasonality three species (C.albiceps, C. putoria, megacephala) that occur Pantanal region.The flies were caught by four Wind Oriented Traps, baited with decayed bovine liver.Traps kept active all over carried out from December 2004 November 2007 at Nhumirim ranch, located...
Horn fly resistance to pyrethroid insecticides occurs throughout Brazil, but knowledge about the involved mechanisms is still in an incipient stage. This survey was aimed identify of horn cypermethrin Mato Grosso do Sul state, Brazil. Impregnated filter paper bioassays using cypermethrin, synergized or not with piperonyl butoxide (PBO) and triphenyl phosphate (TPP), were conducted from March 2004 June 2005 populations (n = 33) all over state. All highly resistant factors (RF) ranging 89.4...

From October 2000 to April 2001, insecticide bioassays were conducted in 18 ranches from 10 counties the states of Mato Grosso and do Sul, Central Brazil. Horn flies wild populations exposed diazinon-impregnated filter papers immediately after collection on cattle, mortality was recorded 2 h. A high susceptibility diazinon observed all tested populations. The LC50s ranged 0.15 0.64 µg/cm², resistance ratios always lower than one (ranging 0.1-0.6). Pyrethroid products, most applied by...
