[Background] Bactrocera cucurbitae is the important pest of Amphisarca in Sourthern China. The objective of this study was to examine the fly movement of B. cucurbitae to between control this fly. [Method] Based on the known biological characteristics, artificial climate chamber and some other equipment were used to study the effects of temperature and light changes on fly behavior activity of B. cucurbitae. [Result] The results showed that the fly activities increased with temperature starting at 15℃ with an optimum temperature between 20 and 30℃. Flying activities were obviously the greatest at temperatures above 35℃ and the least when temperatures dropped under 10℃. The activity percent of B. cucurbitae is more than 50% at 25~40℃, but it is 0% at 10、15 and 45℃ respectively. Light intensity also affected fly behavior with fly activities increasing over 2400 lx and reaching a peak at 9600 lx. Extreme light intensity (12000 lx) inhibited flight behavior. The number of take-off activity of B. cucurbitae increased with the increase of light intensity. [Conclusion and significance] Extremes in temperature and light intensity may limit flight activity of B. cucurbitae. Moderate high temperature can encourage fly behavior.
