Zusammenfassung: | The bronze bug Thaumastocoris peregrinus is native from Australia and has been detected in Brazil since 2008, causing damages in eucalypt plantations. This insect feeds on the phloem-sap, preferentially on the oldest leaves, that evolves into chlorotic spots and later in bronze spots. In high infestations, plant defoliation may occur. Although the feeding damage results in losses, the efforts for monitoring are still scarce. Therefore, by using adhesive traps colored differently we sought to determine which color would be the best for monitoring this insect in eucalypt plantations. White and yellow traps are efficient for field monitoring and should be installed in the top of the trees located in the edge of the plots. Keywords: forest pests; Eucalyptus spp.; bug bronze. 0 percevejo-bronzeado-do-eucalipto Thaumastocoris peregrinus e originario da Australia e foi detectado no Brasil em 2008, causando danos em plantacoes de eucalipto. O percevejo suga a seiva, principalmente das folhas mais velhas, onde se formam pontos cloroticos que, posteriormente, tornam-se manchas bronzeadas. Em casos extremos pode ocorrer desfolhacao. Os trabalhos sobre o monitoramento do inseto ainda sao escassos perante os registros de danos em plantacoes de eucalipto. Diante disso, com o uso de diferentes cores de armadilhas adesivas, buscou-se determinar qual seria a melhor coloracao para uso no monitoramento de Thaumastocoris peregrinus em plantios de eucalipto. As armadilhas de cor branca e amarela sao eficientes para monitoramento de infestacoes no campo e devem ser instaladas proximo a copa das plantas e na borda dos talhoes. Palavras-chave: praga florestal; Eucalyptus spp.; percevejo bronzeado. |
