| Résumé : |
The scarab beetle Rhinyptia infuscata Burmeister and the millet head miner Heliocheilus albipunctella de Joanis are important panicle pests of pearl millet. Studies were conducted to better understand pest bioecologies and behavior as prerequisites to the development of improved control techniques. The scarab beetle is distributedin a large area in Niger and causes substantial damage to millet in most survey areas. Results showed that feedind and mating activities of the scarab beetle are more pronounced between 2000 and 2400 with peak activity around 2300. Larval behavior of the millet head miner with regard to migration was also studied. Results showed that larval migration occurred mostly between 2400 and 0600. The relevance of these findings to the management of these key millet pests is discussed. |
