Resumo: | In this work, we studied the toxicity of mustard oil to 18 populations of Tribolium castaneum (Coleoptera: Tenebrionidae) collected in Brazil, and the correlation with their resistance and phosphine. There is relationship between toxicity of mustard oil and respiratory rate; we were seeking evidence that would be determinant of susceptibility to mustard oil. Additionally, evaluated the toxicity of mustard oil to immature stages of T. castaneum and was investigated of respiratory rate and body mass of insects, and relationship between respiratory rate and oil in the toxicity study. The mustard oil, with 90% of the volatile component ITCA was diluted in vegetable oil from soybeans, in the proportion of 0.5:9.5v/v, to get on oily solution 4.5% of ITCA. The concentrations were used to assess the adult and immature stages ranged from 2.25 to 5.62 μL L-1. Results of mortality were used to generate the concentration-response curves. LC50 and LC95 were estimated too and their used to calculate reasons of toxicity (RT). Patterns of instantaneous rate of growth instantaneous (ri), respiratory rate (CO2 production) and body mass were assessed to each adult. Last two parameters were used to immature stages evaluation. Nonresistance was showed in all populations of T. castaneum to mustard oil, and no cross-resistance between phosphine and mustard oil was showed too. We observed different reproductive patterns, respiratory and body mass among adult populations. However, no relationship was found between these variables and toxicity of mustard oil. The essential oil of mustard showed toxicity to all immature stages of T. castaneum evaluated. The toxicity data also indicated difference remarkable in susceptibility among stages of development in insect populations evaluated. In insect stages, eggs and young larvae were more susceptibility and more tolerant, respectively. The respiratory rate was influenced by stage of development of insects and their body mass. However, no relationship was observed between respiratory rate of insects and toxicity of mustard oil. All populations not showed any resistance to mustard oil and cross-resistance between mustard oil and phosphine that was toxic to all stages of development of insects. Wherefore, may be possible mustard oil will become an important alternative fumigant and is use in management programs of resistance to phosphine. |

Verificaram-se a relação da toxicidade do óleo de mostarda e a taxa respiratória buscando-se evidenciar se esta última seria determinante de susceptibilidade ao óleo de mostarda. Adicionalmente, avaliou-se o efeito tóxico do óleo de mostarda para as fases imaturas de T. castaneum e foi averiguada a massa corpórea e a taxa respiratória dos insetos, bem como a relação da taxa respiratória com a toxicidade ao óleo em estudo. O óleo de mostarda, com 90% do componente volátil ITCA, foi diluído em óleo vegetal de soja, na proporção de 0,5:9,5 v/v, para obter solução oleosa de 4,5% de ITCA. As concentrações utilizadas para avaliar as populações adultas e fases imaturas do inseto variaram entre 2,25 a 5,62 μL L-1. Os resultados de mortalidade obtidos foram utilizados para gerar as curvas de concentração-resposta, e as CL50 e CL95 foram estimadas e usadas para calcular as respectivas razões de toxicidade (RT). Os padrões de taxa instantânea de crescimento instantâneo (ri), taxa respiratória (produção de CO2) e massa corpórea foram avaliados para cada população adulta, além de estes dois últimos parâmetro terem sido avaliados para as fases imaturas. Nenhuma das populações estudadas apresentou resistência ao óleo de mostarda e não houve resistência cruzada entre o óleo de mostarda e a fosfina. Foram observados diferentes padrões reprodutivos, respiratórios e de massa corpórea entre as populações adultas. Porém, não houve relação destas variáveis e a toxicidade do óleo de mostarda. O óleo essencial de mostarda se apresentou tóxico para todas as fases imaturas de T. castaneum avaliadas. Os dados de toxicidade indicaram também uma notável diferença na susceptibilidade entre os estágios de desenvolvimento do inseto nas populações avaliadas, tendo os ovos sidos mais susceptíveis e as larvas jovens mais tolerantes. A taxa respiratória foi influenciada pelo estágio de desenvolvimento do inseto e por sua massa corpórea. No entanto, não foi observada relação entre as taxas respiratórias dos insetos e a toxicidade ao óleo de mostarda. Como nenhuma população apresentou resistência ao óleo de mostarda e resistência cruzada entre óleo de mostarda e à fosfina, e o mesmo foi tóxico para todas as fases de desenvolvimento do inseto, é possível que o óleo de mostarda se torne um importante fumigante alternativo e seja usado nos programas de manejo de resistência à fosfina.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de ViçosaMestrado em EntomologiaUFVBRCiência entomológica; Tecnologia entomológicaÓleo de mostardaManejo de resistênciaPragas de grãos armazenadosOil of mustardResistance managementStored grain pestsCNPQ::CIENCIAS AGRARIAS::AGRONOMIA::FITOSSANIDADE::ENTOMOLOGIA AGRICOLASusceptibilidade de Tribolium castaneum ao óleo essencial de mostarda e persperctivas de manejo de resistênciaSusceptibility of Tribolium castaneum to essential oil of mustard and perspectives resistance managementinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFVORIGINALtexto completo.pdfapplication/pdf960144https://locus.ufv.br//bitstream/123456789/3887/1/texto%20completo.pdf411396927d616d5dfb046fc14f5485d5MD51TEXTtexto completo.pdf.txttexto completo.pdf.txtExtracted texttext/plain75897https://locus.ufv.br//bitstream/123456789/3887/2/texto%20completo.pdf.txt307e3119751a58b444b14543513a4631MD52THUMBNAILtexto completo.pdf.jpgtexto completo.pdf.jpgIM Thumbnailimage/jpeg3711https://locus.ufv.br//bitstream/123456789/3887/3/texto%20completo.pdf.jpg013c5f6392f949a57f08827a30a3ee79MD53123456789/38872016-04-10 23:00:46.864oai:locus.ufv.br:123456789/3887Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452016-04-11T02:00:46LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
