Abstract
Alguns aspectos biológicos de Trichogramma galloi Zucchi, 1988 (Hymenoptera: Trichogrammatidae) criados em ovos de Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae), foram estudados em laboratório a 26±2ºC; UR 60±10% e fotofase de 12 horas. Os resultados obtidos mostraram um período médio de desenvolvimento pré-imaginal de 9,46±0,7 dias e uma viabilidade média de 78,05%. O número médio de T. galloi emergido por ovo do hospedeiro foi de 2,29. Nas criações em laboratório, as fêmeas de T. galloi foram predominantes. A longevidade de machos e fêmeas foi, em média 3,26±0,12 dias (sem alimento) e 6,36±0,19 dias (alimentando-se com mel). Os ovos de D. saccharalis de primeiro dia apresentaram parasitismo médio de 79,3±5,25% e os de segundo dia 55,2±2,33%.
Some biological aspects of the parasitoid Trichogramma galloi Zucchi, 1988 (Hymenoptera: Trichogrammatidae) reared on eggs of Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) were studied in the laboratory, at 26ºC, UR 60±10% and 12 hours photophase. The studies showed a life cycle, from egg to adult, of 9.46±0.7 days and a survival rate of 78.05%. The mean number of T. galloi emerged by egg of sugar cane borer was of 2.29. Females were predominant in the laboratory rearing and the longevity of males and females was, on the average, 3.26±0.12 days (without feeding) and 6.36±0.19 days (feeding with honey). The parasitism was between 79.3±5.25% and 55.2±2.33%, in eggs of first and second days, respectively.
