As armadilhas luminosas e sexuais como meio de estudo das populações de Mythimna unipunctata (HAW.) (Lep., Noctuidae).

Abstract

Armadilhas luminosas e sexuais foram instaladas em diferentes localidades da ilha de São Miguel (Lagoa do Congro, Altiprado, Ribeira Grande, Caldeiras, Remédios, Ponta Garça, Povoação), funcionando como a técnica básica do método de previsão dos riscos devidos às populações de Mythimna unipuncta (Haworth) (Lep., Noctuidae), e permitindo ainda efectuar um estudo concernente à eficácia destes dois tipos de armadilhas. O número de machos capturados nas armadilhas luminosas foi globalmente superior ao das armadilhas sexuais. Por outro lado, à excepção de uma ou outra semana, houve uma coincidência temporal quanto às capturas obtidas num e noutro tipo de armadilhas. A utilização das armadilhas sexuais, tal como a das luminosas, permite estudar a dinâmica de populações de M. unipuncta e elaborar uma previsão dos riscos para uma dada região. Esta técnica é assim essencial para um serviço de avisos agrícolas, tendo em vista a prática da luta integrada.
