Nombre: Sternochetus mangiferae (F.)
Posición taxonómica:
Animalia: Arthropoda: Insecta: Coleoptera: Curculionidae
Nombre común: mango seed weevil; mango weevil; mango nut or stone weevil

The mango seed weevil's distribution in the Caribbean basin is increasing.

Preocupación: This pest is not known to occur in North America, except in Hawaii. Detections are problematic due to the cryptic nature of larvae within seeds. This weevil has been intercepted from the Caribbean Basin several times in Puerto Rico and the U.S. Virgin Islands, and is occasionally intercepted at mainland U.S. ports.

Hospedantes: Complete development is only achieved in mangoes. Laboratory reports of larvae on potatoes, peaches, Litchi chinensis, plums, Phaseolus vulgaris and apples all resulted in larvae unable to complete development.

Australasia and Oceania, Asia, Africa, North America (Hawaii), Caribbean (Previous: Barbados, Dominica, Guadeloupe, Martinique, St. Lucia, Trinidad and Tobago; New: British Virgin Islands, Grenada, Montserrat, St. Vincent and the Grenadines), South America (French Guiana)

Cuarentenas: The mango seed weevil is a quarantine pest for CPPC, IAPSC, NAPPO and OIRSA.

Estrategias de detección
The seed is generally the site of complete development. It is impractical to distinguish between infested and uninfested seeds unless they are cut open. As infected fruit is often not visibly damaged, a seed-splitting device is required for detection. A typical device is a guillotine made from a sharpened machete whose blade is anchored at its tip by a pin. USE EXTREME CAUTION WHEN SPLITTING SEEDS! Any seed suspected of infestation should be examined with a hand lens after splitting.

The complete distribution of this pest in the Caribbean is not currently known. USDA-PPQ officers at various ports of entry have commonly intercepted it in mangoes brought by air passengers from Caribbean countries listed in the distribution above.
