Abstract

A detection survey under the "Enhancing the Export Competitiveness of the Philippine Super Mango" program funded by USDA Food for Progress was undertaken in 7 regions of Luzon, 3 regions in Visayas and 6 regions in Mindanaoto determine the presence/absence of the Mango Pulp Weevil (MPW), Sternochetusfrigidus and Mango Seed Weevil (MSW), Stenochetusmangiferae. MPW and MWS are mango pests of quarantine significance. Strong scientific evidence that will prove absence of these pests in the Philippines (except for Palawan) will lead to area freedom certification which will allow sourcing of mangoes for export from different areas of the country. This will also allow access to potential markets which have restrictions on mango importation from countries where these weevils are present. The project covered a 10-month survey which included the "off" and "on" season production of mangoes from September 2006 to June 2007 (Luzon, excluding southern Palawan), October 2007 to June 2008 (Visayas)and November 2008 to August 2009 (Mindanao). The Bureau of Plant Industry was the lead-implementing agency. Low Monitoring Survey (LMS) was also conducted after the three year detection survey. About 234,306 bearing mango trees were examined by canopy beating and bark examination from 79 provinces and their fruits (2,688,975) were dissected for the presence of the weevils. Based on the results of the survey, not a single specimen (egg, larva, pupa, adult) of MPW and MSW was recovered. This indicated that both MPW and MSW are absent in the Philippines. This survey provided strong scientific evidence for the non-existence of mango pulp weevil (except in southern Palawan) and mango seed weevil in the country thus, this information will support the claim for area freedom from these weevils.
