Abstract: 
  • The biology of Scymnus (Pullus) argentinicus Weise on Schizaphis graminum at the temperatures 20, 25 and 30°C was studied. The temperatures of 25 and 30°C were favorable to S. (Pullus) argentinicus development. The average of the incubation period was 3.24 days and the larval development was 8.43 days at 25°C. The duration of the instars and pre-pupal and pupal periods was significantly shorter at 25 and 30°C. The percentage of emerging adults was higher at 30°C (98%) while at 20°C this percentual was 82%.
  • Estudou-se a biologia de Scymnus (Pullus) argentinicusWeise sobre a presa Schizaphis graminum a 20, 25 e 30oC. As temperaturas de 25 e 30oC foram favoráveis ao desenvolvimento de S. (Pullus) argentinicus. O período embrionário médio foi de 3,24 dias e o estádio larval de 8,43 dias a 25oC. A duração média dos ínstares e os períodos pré-pupal e pupal foram significativamente menores a 25 e 30oC. O percentual de adultos emergidos foi maior a 30oC (98%) ao passo que a 20oC houve 82% de emergência.
