Abstract:

Objective　To measure the sex-specific flight behavior of Musca domestica for the formulation of prevention and control strategies. Methods　The tethered flight of female and male adults of M. domestica aged 1, 5, 9, 13, 17, 21 and 25 days were measured. Flight behaviors including; longest distance, longest duration and average speed in the longest journey of a single flight, were compared between sexes. Results　Significantly different flight capacities were seen between male and female adult flies. Newly eclosed males were far behind the females of the same age in this regard. The highest flight capacity occurred at different ages between sexes. In female flies, the highest flight capacity occurred on day 9, with a distance and duration of 438.72 m and 818.01 s, respectively. In contrast, two days of high flight capacity were observed in male flies, on days 9 and 17. The highest flight capacity in males was on day 17, with a distance and duration of 642.91 m and 1385.21 s, respectively. As for the average speed in a single farthest flight, the male flies recorded the highest value on day 9 with a rate of 0.66 m/s while females presented with two peaks on day 9 and day 17, with a rate of 0.58 m/s on day 17. Conclusion　The flight capacities of M. domestica are significantly different between sexes.
