Abstract

The biology of Scymnus (Pullus) argentinicus Weise on Schizaphis graminum at the temperatures 20, 25 and 30oC was studied. The temperatures of 25 and 30oC 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 25oC. The duration of the instars and pre-pupal and pupal periods was significantly shorter at 25 and 30oC. The percentage of emerging adults was higher at 30oC (98%) while at 20oC this percentual was 82%.
