A nonspecific carboxylesterase (esterase 6) of Drosophila melanogaster shows greater activity in adult males than in females and is highly concentrated in the anterior ejaculatory duct of the reproductive tract of the male. Esterase 6 is depleted in males by copulation and is transferred to females early during copulation as a component of the seminal fluid. That esterase 6 may be involved in a system controlling the timing of remating is suggested by differences in the activity of this enzyme in a strain of Drosophila selected for a decrease in time to remating and by differences in the timing of remating in females initially inseminated by males lacking or having active esterase 6.
黑腹果蝇的一种非特异性羧酸酯酶（酯酶6）在成年雄性果蝇中的活性高于雌性，并且高度集中在雄性生殖道的前射精管中。酯酶6在雄性果蝇交配后会减少，并在交配早期作为精液的一部分转移到雌性果蝇体内。通过对一个为缩短再次交配时间而选择的果蝇品系中这种酶活性的差异，以及对最初由缺乏或具有活性酯酶6的雄性果蝇授精的雌性果蝇再次交配时间的差异，可以推测酯酶6可能参与了一个控制再次交配时间的系统。
