摘要 雄性苹果蛆蝇，Rhagoletis pomonella (Walsh)，与单独笼养时相比，与 1 只或更多雌性或与其他几只雄性一起笼养时，出现在地蜡圆顶（产卵部位和交配聚集部位）上的相对频率要高得多。随后的现场和实验室实验表明，引起这种更大程度的雄性聚集的主要刺激因素是一种未知的化学物质，该化学物质由两性沉积在苹果和地蜡圆顶的表面（但成熟雌性的沉积量更大），导致到达的雄性在那里花费的时间是未经处理的水果的两倍。这种化学物质的存在并没有引起雄性对这种水果的更大的吸引力。与未经处理的圆顶相比，雄性在含有化学物质的圆顶上居住时间较长的结果是雄性聚集，并且随之而来的相互相遇和尝试交配的频率更高。虽然这种化学物质可以逮捕雄性，但我们推测，仅仅检测到它的存在就足以使雄性留在附近并监视雌性。
Abstract Male apple maggot flies, Rhagoletis pomonella (Walsh), were present on ceresin wax domes (the site of oviposition and the site of assembly for mating) in much greater relative frequency when caged with 1 or more females or with several other males than when caged alone. Field and laboratory experiments subsequently revealed that a principal stimulus eliciting this greater degree of male assembly was an unidentified chemical(s) deposited on the surface of apples and ceresin domes by both sexes (but in greater amount by mature females) causing arriving males to spend up to twice as much time there as on untreated fruit. The presence of the chemical did not elicit any greater attraction of males to the fruit. The consequence of the longer male residency on domes with the chemical was male aggregation and an ensuant higher frequency of mutual encounter and attempted copulation than on untreated domes. While the chemical acts to arrest males, we theorize that mere detection of its presence may be sufficient to cause males to remain in the vicinity and watch for females.
