.1 The sexual competitiveness of sterile melon fly males [ Ducus (Zeugodacus) cucurbitue Coquillett] was estimated under field conditions. 2 The value of competitiveness was about 0.8 for flies in the fifth to tenth generation from the beginning of mass‐rearing, but decreased to about 0.2 in the eighteenth generation. 3 The sexual competitiveness estimated using laboratory data was near unity even in the final stage of our study. 4 It was concluded that the field evaluation of sexual competitiveness is essential to determine the quality of the insects reared for purposes of pest control.
