Abstract: The flight performance of laboratory-reared winged adults of the bird cherry oat aphid Rhopalosiphum padi (Linnaeus), was investigated with a flight-mill system at several temperature grades (8°C - 30°C ). The results showed that the temperature range of 12°C-20°C was suitable for flight of the bird cherry oat aphid, the average flight distance was 6. 614-8. 219km and the average time of flight was 5.074-7.003 h. At 15°C , the maximum flight distance and flight duration reached 26.231km and 21.53h respectively. It was difficult for the bird cherry oat aphid to take off at 8°C, and both the flight distance and flight duration were short after take-off. At 23°C and above, the aphid was easy to take off, but the flight distance and flight duration were becoming shorter gradually with the rise of temperature. At 30°C, the aphid stopped flying shortly after take-off. The flight speed increased with increase of temperature, the average speed was 0.781 km/h at 8°C and 1.605 km/h at 30°C.
