The phenomenon of aggregated oviposition in blackflies (Diptera: Simuliidae) was investigated under controlled laboratory conditions, using wild-caught females of the Simulium damnosum complex in Sierra Leone. A method was developed for inducing Simulium females to lay eggs, and used as a bioassay to measure the responses of gravid S. damnosum s.l. to freshly laid eggs of the same species complex. In a series of two-choice tests, significantly more ovipositing flies chose substrates already containing eggs over control substrates (P = 0.004). The time from introduction of flies into the oviposition system to the onset of egg-laying was significantly less when eggs were already present (P = 0.049). Flies responded more quickly when more eggs were present and the relationship between egg-batch number and the time of this response was curvilinear (P = 0.012). Ecological advantages and disadvantages of such aggregation behaviour and the possible role of semiochemicals in its mediation are discussed.
在实验室控制条件下，利用在塞拉利昂野外捕获的黑蝇属（双翅目：蚋科）雌性个体，对黑蝇的聚集产卵现象进行了研究。开发了一种诱导蚋科雌性个体产卵的方法，并将其用作生物测定法，以测量感染疟原虫的黑蝇复合种对同一物种复合体新鲜产下的卵的反应。在一系列二选一测试中，与对照底物相比，显著更多的产卵蝇选择了已经含有卵的底物（P = 0.004）。当已经有卵存在时，从将蝇引入产卵系统到开始产卵的时间显著缩短（P = 0.049）。当存在更多卵时，蝇的反应更快，并且卵块数量与这种反应时间之间的关系是曲线关系（P = 0.012）。讨论了这种聚集行为的生态利弊以及信息化学物质在其中的介导作用。 （注：原文中“gravid S. damnosum s.l.”翻译可能有误，推测可能是“感染疟原虫的黑蝇复合种”，因为“gravid”是怀孕的意思，这里结合语境推测可能是指感染疟原虫的状态，“s.l.”是“sensu lato”的缩写，意思是“复合种”，整体翻译可能需要根据更准确的专业知识进一步调整。）
