A curva de voo dos adultos de Mesapamea storai (Rebel, 1940), Phlogophora meticulosa (Linnaeus, 1758) e Sesamia nonagrioides (Lefebvre, 1827) (Lep., Noctuidae) foi estudada através de armadilhas luminosas do tipo Pensilvânia, instaladas em três localidades da ilha de São Miguel (Ribeira Grande, Arribanas e Lagoa do Congro), entre Julho de 1988 e Dezembro de 1989. Para as três localidades, foram evidenciadas flutuações de densidade consideráveis, sendo as espécies observadas continuamente (P. meticulosa) ou entre Setembro e Dezembro (s. nonagrioides). Contrariamente, M. storai foi capturada somente no fim do Verão de 1988 e na Primavera seguinte, isto na Lagoa do Congro. Para qualquer das espécies, ambos os sexos foram capturados simultaneamente, não se tendo verificado que o sex-ratio se desviasse significativamente de 1:1.
ABSTRACT: The adult flight periods of Mesapamea storai (Rebel, 1940), Phlogophora meticulosa (Linnaeus, 1758) and Sesamia nonagrioides (Lefebvre, 1827) (Lepidoptera, Noctuidae) were studied between July of 1988 and December of 1989, at Ribeira Grande, Arribanas and Lagoa do Congro on the island of São Miguel, using Pennsylvania black light traps. While there was evidence of considerable fluctuations in density, two species were present continuously (P. meticulosa) or between September and December (S. nonagrioides) at the three locations. In contrast M. storai was only captured at the end of the summer of 1988 and in the next spring at Lagoa do Congro. For any given species both sexes were captured simultaneously, and in no case did the sex ratio does deviate significantly from 1:1.
