The survey, achieved in the west of Burkina in laboratory conditions (average temperature of 28,21°C and average relative humidity of 73%), aimed to value some biologic parameters of Antigastra catalaunalis. Thus, twenty couples of the pyrale have been followed for the survey of the punter and sixty larvas for the survey of the features and the lengths of the different larval stages. Besides, the bursting rate of the eggs, mortality rate of the larvas, chrysalisation rate of the larvas and emergence rate of the adults have been valued. The results reveals that the females of A. catalaunalis lay 299 eggs on average during 5,5 days with a rate of bursting of 67,06%. Besides, the pyrale passes by five larval stages and has an average development cycle of 21,95 days for the males and 24,45 days for the females. It is necessary to note that the sex-ratio is 1: 1,58. the L1 larvas presented the strongest mortality (23,33%). otherwise, the chrysalisation rate of the larvas was 90,37% and the emergence rate of the adults was 81,57%. At last, it would be interesting to quantify the impact of A. catalaunalis on the different varieties of sesame popularized in Burkina.
