Abstract : The flight activity of the oriental fruit fly (B. dorsalis) was observed for 24 h in a mango orchard using methyl eugenol-baited traps in Yunnan, China in 2004. The effects of light, temperature and relative humidity on the flight activity of the pest were also determined. Male adults fly during the daytime and not at night, with flying peaks at 8-9.00 and 18-20.00 h. The number of flights of the pest was lowest at 2.00 pm. The pest was more active at a light condition of 100-200 lux. Air temperature was generally suitable for the flight activity of B. dorsalis. Relative humidity of less than 60% adversely affected the flight activity of the fly.
