Farmers' perceptions of yield losses due to insect pests and methods for assessment in pearl millet uri icon


  • On-farm surveys conducted in western Niger to establish a better understanding of millet farmers'' perceptions of crop loss and methods for assessment indicated that farmers were aware of the benefits to be derived from crop loss assessment. Findings from these surveys also showed that on average 82.6% viewed crop loss assessment as important versus 17.4% who viewed loss assessment as unimportant. Among sample farmers, an average of 85.3% assessed crop loss qualitatively versus 14.7% quantitatively. Visual assessment of damage was most preferred, followed by insect numbers as a means for assessing crop losses. On average, 50.6% versus 40.9% of sample farmers across village farms attributed crop losses primarily to the pest damage, then insect numbers, respectively. Implications of these findings and applications for pearl millet pest management are discussed
