Abstract : Field sanitation was evaluated in Hawaii as a method for reducing infestations of mangoes by the curculionid Cryptorhynchus mangiferae [Sternochetus mangiferae]. All fallen fruit and seeds from under 4 isolated orange trees were removed twice a week during the fruiting period. In the following season, infestation data from these trees were compared with those for an untreated orchard. Field sanitation did not reduce the incidence of the pest because the maximum infestation rates in fruits of all tested trees were greater than from those in the orchard. Evidently, adults can disperse further than previously thought.
