Several studies have estimated yield loss caused by FAW especially surveys. Can loss assessment based on farmer perception overestimate the actual losses?

    This argument remains valid, especially with the sudden arrival of a dramatic invasive pest like FAW. The discussion can only be settled through a rigorous comparison of field trials with farmer estimates, preferably both with individual farmers and through community surveys.
