Males of the melon fly make lek on which each male compete for good calling site where a female comes and copulation occurs. Mass-reared(R) males were inferior to the wild males in competing ability among males on lek. More over the rate of remating was higher and duration to remating was shorter when the females mated with R-males, showing that R-males were also inferior to the wild males in competing ability of post copulation.Two types of mating were discovered: 1) courtship type where a male engages in wing vibration after encounter with a female for some time and then try to mount for copulation, and non-courtship type where a male try to mount just after encounter without wing vibration. R-males could copulate with wild females only when engaging in non-courtship type but could not when engaging in courting type, suggesting that wild females discriminated against R-males through the courting wing vibration of males.When insects are reared under artificial conditions, some level of domestication would be expected, and the domestication could resulted in deterioration in quality of reared insects. So if we want to use the sterile insect technique, the releasing program should be terminated as possible as short.

瓜蝇的雄性在其上制造lek，每个雄性在其上竞争好的呼叫位置，在那里雌性到来并进行交配。大规模饲养（R）的男性不如野生男性之间的竞争能力列克。此外，雌虫与R-雄虫交配时，再交配率较高，再交配持续时间较短，表明R-雄虫在交配后的竞争能力上也不如野生雄虫。1）求偶型，雄性在与雌性相遇一段时间后进行翅膀振动，然后试图交配，和非求偶型，即雄鸟在没有翅膀振动的情况下尝试在相遇后立即登上。野生雄虫只有在非求偶型时才能与雄虫交配，而在求偶型时不能与雄虫交配，表明野生雌虫通过雄虫求偶时振动翅膀的方式来歧视雄虫。因此，如果我们想使用不育昆虫技术，释放程序应尽可能短的终止。
