在昆虫中，雄性已经进化出辨别潜在配偶的能力，以避免徒劳的交配尝试。在双翅目，求偶和交配行为的物种，不歧视潜在的配偶很少被研究。在这项研究中，我们调查了交配尝试的柄眼苍蝇，Sphyracephala detrahensmales，不从事任何可观察到的交配前求爱行为。我们发现，性成熟的男性试图与成熟的男性和不成熟的成年人交配的性别，经常与成熟的女性。成功的交配只发生在成熟的雌性。不成熟的女性拒绝安装男性振动他们的身体和不成熟和成熟的男性弯曲他们的腹部向下。不同性别和成熟度个体表皮碳氢化合物组成的比较表明，表皮碳氢化合物的配置文件是相似的，无论性别和性成熟。因此，我们认为视觉或化学信息对男性没有多大用处。区分可接受的同种配偶。由于复杂的配偶歧视行为导致额外的时间和精力成本时，歧视是困难的，S。通过增加交配尝试的次数，生殖成功率可能会增加。与本文相关的数字视频图像可在 http://www.momo-p.com/showdetail-e.php? movieid=momo211123sd01a , http://www.momo-p.com/showdetail-e.php? movieid=momo211123sd02a , http://www.momo-p.com/showdetail-e.php? movieid=momo211123sd03a 得双曲正弦值. http://www.momo-p.com/showdetail-e.php? movieid=momo211123sd04a .
Among insects, males have evolved the ability to discriminate potential mates to avoid vain mating attempts. In Diptera, courtship and mating behaviors of species that do not discriminate potential mates have rarely been studied. In this study, we investigated copulation attempts of the stalk-eyed fly,Sphyracephala detrahensmales, which do not engage in any observable pre-copulatory courtship behavior. We found that sexually mature males attempted to copulate with mature males and immature adults of both sexes, as frequently as with mature females. Successful copulation only occurred with mature females. Immature females rejected mounting males by vibrating their bodies and immature and mature males by incurving their abdomen downward. Comparison of the cuticular hydrocarbon components of individuals of different sexes and maturity levels indicated that the cuticular hydrocarbon profiles were similar regardless of the sex and sexual maturity. Therefore, we suggest that visual or chemical information are of little use for malesS. detrahensin discriminating receptive conspecific mates. Since elaborate mate discrimination behaviors lead to additional time and energy costs when discrimination is difficult,S. detrahensmay increase reproductive success simply by increasing the number of copulation attempts.
