Black fly
Pests damage the host by extracting sap from the lower surface of leaves, resulting in stunted leaves. Whereas curling and crinkling of leaf lamina may occur with heavy adult infestation (Das, 2010). Following adult emergence from puparia (last nymphal instar), the exuviae remain attached to the lower surface of the leaves, making the affected leaves unsuitable for consumption and marketing.
