Resumo: The insect Tribolium confusum is considered one of the most important storage pests due to the significant reductions either in quantity or quality of cereal grains. Alternatives to chemical synthesis insecticides should be found due to their obvious disadvantages. Those alternatives should be specific to target plant enemies, with no risks to the ecosystem. Hence, the aim of this work was to study the insecticidal effect of a monoterpene, 2-methyl-5-(1-methylethenyl)-2-cyclohexenone, on Tribolium confusum. Acute essays were performed with the following monoterpene concentrations: pure 2-methyl-5-(1-methylethenyl)-2-cyclohexenone, 10, 1, 0.1 and 0.01%. To compare the monoterpene insecticidal activity, tests with a standard insecticide, pirimiphos-methyl, were also conducted. Mortality was observed at one, two, three, six, 12, 24, 36, 48 and 96 hours. The obtained results showed that 2-methyl-5-(1-methylethenyl)-2cyclohexenone behaviour was comparable to that of the pirimiphos-methyl. Therefore, further studies should be conducted to confirm the bioinsecticidal potencial of this monoterpene.

Perante as desvantagens do uso de insecticidas químicos de síntese, procuram-se alternativas específicas para os organismos - alvo, que causem o mínimo de prejuízos no ecossistema. O objectivo deste trabalho foi estudar, em laboratório, o efeito insecticida de um monoterpeno, 2-methyl-5-(1-methylethenyl)-2-cyclohexenone, sobre Tribolium confusum. Foram realizados ensaios de toxicidade aguda com as seguintes concentrações: 2-methyl-5-(1-methylethenyl)-2-cyclohexenone puro, 10, 1, 0,1 e 0,01%. Foi ainda estudada a actividade do insecticida padrão, pirimifos-metilo, puro. A mortalidade foi registada uma, duas, três, seis, 12, 24, 36, 48 e 96 horas após o início da experiência. Os resultados mostraram que o monoterpeno, na sua forma pura, teve um comportamento comparável ao do pirimifos-metilo, justificando-se, por isso, a realização de mais estudos, tendo em conta as características bioinsecticidas reveladas neste estudo.Sociedade de Ciências Agrárias de Portugal2019-01-03T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.19084/rca.16271eng2183-041X0871-018XCosta, MartaMartins, FilipeSilva, Aida Moreira daGalhano, Cristinainfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-09-06T09:24:15Zoai:ojs.revistas.rcaap.pt:article/16271Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T15:30:45.104311Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
