Currently mango exports to major markets in the USA and Australia from Mindanao and the rest of the Philippines (with the exception of the small island of Guimaras) are prohibited, due to uncertainty over the reported presence of mango seed and pulp weevils. Since no effective control methods are available to provide quarantine security (either pre or post harvest), establishing accepted 'area freedom' status is seen as the only way to open export markets. This activity was a six month detection survey for both weevils. Scientists gathered evidence to establish that the weevils were absent from Sarangani Province and conducted low-level monitoring in Davao del Sur to complement internal quarantine measures being funded by that province. The longer-term intention was to provide information to support area freedom certification and thus promote the expansion of export opportunities for mango producers in Mindanao.
