Summary : In Benin, damage caused by stem borers are a threat to rice production. The present study aimed at evaluating farmer knowledge of these pests in order to find participative solutions for their monitoring and control in rural areas. An agronomic survey was carried out with 151 producers in the regions of Zou, Collines and Couffo where specimens of rice stem borers and samples of their damage were exhibited to farmers for identification. Field visits were also undertaken in order to observe farmer knowledge. The results recorded show that rice producers in Benin have good knowledge of the main rice stem borers such are Sesamia calamistis Hampson (Lepidopera : Noctuidae), Chilo zacconius Bleszynski (Lepidoptera : Pyralidae), Maliarpha separatella Ragonot (Lepidopera : Pyralidae) and Diopsis spp. (Diptera : Diopsidae). Damages caused by stem borers, such as white panicle and dead heart, are also very well recognized by the farmers. The proven knowledge of rice stem borers by farmers would allow agricultural services to take advantage of farmers’ experience and knowledge by associating them in local diagnosis and pest control measures. |
