The project aimed to determine the major pest fruit fly species, and their preferred fruits, in the regions of Vietnam to introduce suitable pre-harvest control by bait-spraying.
Vietnam needs comprehensive information about local fruit fly species in order to develop an export trade in fresh fruits and certain vegetables. Also, in north-western Vietnam new plantings of temperate and subtropical fruits, established partly for development of poor areas and partly for opium substitution, are suffering close to 100% fruit fly damage. Farmers have become disillusioned and will abandon the development schemes unless solutions are found quickly. This project ascertained the economically important species of fruit fly and the host fruits of every species in each region studied. It also measured damage levels of the major species and their seasonality, and introduced environmentally friendly, pre-harvest control by bait-spraying. Training programs assisted with identification, biological studies, and development and implementation of field control campaigns. The project was conducted alongside an AusAID initiative that aimed to implement field control of fruit flies and included the results of the ACIAR work.
