| Résumé : |
The main panicle pests of pearl millet recorded during a National Resources Institute, (UK), project in North West Mali (1985-91) are listed. The importance of operational crop loss assessment, crop damage and pest monitoring is emphasized as a means of interpreting pest dynamics, detecting population trends and forecasting ahead of the next season. Some pearl millet varieties show pseudo-resistance to grasshoppers, panicle-feeding beetles and other pests. Sorghum varieties, however, combine this factor with intrinsic chemical defenses, making it possible to reduce pest damage to pearl millet by intercropping the two cereals. The importance of rainfall records is explained. Rainfall data may indicate when it is uneconomic to apply chemical insecticides for certain pests such as the millet head miner caterpillar. The difficulties inherent in monitoring concealed and overt damage to millet are discussed. Proposal are made for practical for IPM interventions against panicle pests. Long-term research into genetic engineering in pearl millet is tentatively proposed as the most effective way of improving IPM of panicle and foliage pests. |
