This paper described the effectiveness of immerged falling fruits in water and soil cover with plastic in orchard against oriental fruit fly, Bactrocera dorsalis. The results showed that all stages of the fruit fly larvae immerged in water directly were 100% killed after 4 days (96 hours), and fruit fly larvae were also 100% killed after the falling fruits were immerged in water for 20 days. All stages of the fruit fly larvae infested in falling fruits were also 100% killed after being keeped in the plastic bag 120hrs, exposed on the plastic covered on the orchard soil after 30 days were also 100% killed. It was concluded that both water immerge and plastic cover practices could control the population of fruit fly in orchard.
