PORTUGUES: Em campos de tomate, localizados em diferentes locais e destinados a estudos de avaliacao da eficacia de insecticidas para combater a Heliothis armigera Hbn., foram incluidas parcelas nao tratadas. Proximo dos campos de ensaio, instalaram-se armadilhas luminosas (1982-1984) e com feromonas sexuais INRA (1985-1987 and 1989) para determinacao da curva de voo com base na captura dos adultos. Durante o mesmo periodo de tempo obtiveram-se dados sobre o ataque provocado no tomate pela H. armigera nas parcelas nao tratadas. Os resultados apontam para a possivel existencia de dois voos e, por vezes, inicio de um terceiro.

Trials in tomato, grown under field conditions, were set up in different places for the efficacy evaluation of insecticides to control Heliothis armigera, and untreated plots were included. Near the trial areas, two trap types were set up in the following periods: light traps, 1982-1984; pheromone traps, 1985-1987 and 1989. Adult flight curves were drawn on the basis of weekly catches. At the same time observations carried out in the untreated plots allowed the assessment of the attack of the pest on the fruits throughout the crop development. Results showed that two adult flights and sometimes the beginning of a third one might be found.
