There are however about 1400 mango trees, planted during World War II, that are considered a communal property. Mangos have become inedible since the introduction of Oriental fruit fly. The four fruit fly species that occurred until recently in Nauru have all been introduced from Micronesia, the South Pacific and probably Asia as well. Two species have been eradicated, one is nearly eradicated, the last remaining species will hopefully be eradicated during 2000. It is executed by the Department of Industry and Economic Development .
Every fruit fly species on Nauru was introduced from other countries.
Oriental fruit fly and melon fly have successfully been eradicated by male annihilation. The last flies were trapped in early 1999. Mango fly and Pacific fruit fly eradication is not as easy. Established and maintained a general fruit fly laboratory, including facilities for holding fruit samples collected in the field. Established 41 trapping sites on Nauru.
