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.

Abstract: (french)
L’étude, réalisée à l’ouest du Burkina Faso en conditions de laboratoire (température moyenne de 28,21°C et humidité relative moyenne de 73%), a visé à évaluer quelques paramètres biologiques de Antigastra catalaunalis. Ainsi, vingt couples de la pyrale ont été suivis pour l’étude de la ponte et soixante larves pour l’étude des caractéristiques et des durées des différents stades larvaires. De plus, les taux d’éclosion des œufs, de mortalité des larves, de chrysalisation des larves et d’émergence des adultes ont été évalués. Il ressort des travaux que les femelles de A. catalaunalis pondent en moyenne 299 œufs durant 5,5 jours avec un taux d’éclosion de 67,06%. En outre, la pyrale passe par cinq stades larvaires et a un cycle de développement moyen de 21,95 jours pour les mâles et 24,45 jours pour les femelles. Il faut noter que la sex-ratio est de 1: 1,58. Les larves L1 ont présenté la plus forte mortalité (23,33%). Par ailleurs, le taux de chrysalisation des larves a été de 90,37% et le taux d’émergence des adultes a été de 81,57%. Au terme de cette étude, il serait intéressant de quantifier l’impact de A. catalaunalis sur les différentes variétés de sésame vulgarisées au Burkina Faso.
