A milenar tecnica da queimada usada pelos agricultores primitivos donos de pequenas culturas, e a mesma ainda empregada hoje em dia, para facilitar e agilizar a limpeza dos cerrados com o objetivo de se formar pastagens e agricultura. Alem das particulas e aerossois, as queimadas emitem para a atmosfera uma grande quantidade de gases, dentre eles o dioxido de carbono (CO2), principal gas, de origem antropogonica do efeito estufa, e o monoxido de carbono (CO), gas reativo e toxico quando em concentracoes elevadas. A emissao destes gases, sob a acao do ultravioleta, pode produzir grande quantidade de ozonio (O3) troposferico, o qual alem de toxico, em altas concentracoes, traz serios danos aos ecossistemas. Diante do exposto, procurou-se atraves deste Workshop, reunir tecnicos e pesquisadores de varias instituicoes, direta ou indiretamente envolvidos com o tema central, e assim, atraves de suas apresentacoes e debates, contribuir para melhor elucidar o assunto e nortear futuras decisoes neste ambito. |

BACKGROUND - The control of ticks is challenged by the resistance of tick populations to chemical acaricides. In this study, we evaluated, under laboratory conditions, the efficacy of Heterorhabditis bacteriophora against Rhipicephalus (Boophilus) microplus engorged females with varying body weights (150, 200, 250, 300 or 350 mg per female) or from eight different geographical populations. We also determined the efficacy of H. bacteriophora for tick control under field conditions. RESULTS - R. microplus engorged females with varying body weights exposed to 150 juveniles of H. bacteriophora resulted in a high control efficacy (97.5% to 98.4%). Tests with females from different geographical populations comprised eight tick strains treated with H. bacteriophora and their respective control groups. The biological parameters of females exposed to nematode treatments did not differ significantly and resulted in 89% to 99% of control efficacy. Trials conducted under field conditions were performed in field plots with Megathyrsus maximus grass. Treatment groups received eight cadavers of Tenebrio molitor fully colonized with H. bacteriophora at 1 week prior to the release of female ticks, whereas control groups were untreated. On the first day of the experiment, six engorged females were distributed in each plot. On day 42 and day 63, the apical portion of the grasses with R. microplus larvae were collected and quantified. The population of R. microplus larvae was reduced up to 73.1% in plots treated with H. bacteriophora at day 63 after treatment. CONCLUSION - R. microplus engorged females with varying body weights or from different geographical populations were highly susceptible to H. bacteriophora. The field test demonstrated the efficacy of H. bacteriophora in reducing R. microplus larvae in infested pastures.
