Leafminers feed between the upper and lower surfaces of plant leaves. Such damage, as shown on the tomato plant (right), is negligible as long as it is confined to the leaves. However, in the case of snow peas, these pests attack the product as well. Since they have quarantine status in many European Union countries, leafminers are one of the causes for the reject of many consignments of snowpeas from Africa. icipe’s goal is to assist small-scale farmers in producing immaculate snowpeas, such as the ones pictured (extreme right) graded, and ready for export to EU supermarkets (photo: icipe Horticulture Team).
