Abstract

The Senegalese grasshopper, Oedaleus senegalensis (Krauss, 1877) (Acrididae, Oedipodinae) survives the dry season under natural conditions as diapausing eggs. Females, reared under short photoperiod (10/24 hr), produced eggs which were mostly diapausing eggs, while those reared under long photoperiod (14/24 hr) laid essentially no diapausing ones (less than 3% of diapausing eggs). In addition, females submitted to a photoperiod of 10/24 hr, the percentage of diapausing eggs decreased with increasing female age.

Résumé

Le criquet sénégalais, Oedaleus senegalensis (Krauss, 1877) passe la saison sèche, en milieu naturel, à l'état de diapause embryonnaire. Femelles élevées, sous courte photopériode (10/24 hr) produisaient des oeufs majoritairement à diapause, alors que celles élevées sous longue photopériode (14/24 hr) pondaient essentiellement des oeufs à développement direct (moins de 3% de diapause). On constate par ailleurs que chez les femelles élevées à la photopériode 10/24 hr le pourcentage d'oeufs en diapause diminuait avec le vieillissement des femelles.
