This study evaluates the importance of native bromeliads growing on rocky outcrops interspersed with urbanized areas as breeding sites for the Aedes aegypti (L.) in Vitória, state of Espírito Santo, Brazil. Oviposition traps were installed in backyards of houses in two separate zones. In the first zone houses were up to 50 m away from the rocky outcrops, while in the second zone they were at least at 200 m from the rocky outcrops. Aedes aegypti was significantly more abundant in the latter zone. The finding was that rocky outcrops with native bromeliads, even with the greater availability of potential breeding sites, do not play an important role as breeding sites for A. aegypti. This conclusion supports the hypothesis that the macrobiota of native bromeliads plays an important role in the natural control of A. aegypti. Besides, the interspecific competition between species of mosquitoes and the attractiveness of bromeliads could also be important factors.
本研究评估了生长在散布于城市化区域中的岩石露头处的本地凤梨科植物作为巴西圣埃斯皮里图州维多利亚市埃及伊蚊（L.）繁殖场所的重要性。在两个不同区域的房屋后院设置了产卵诱捕器。在第一个区域，房屋距离岩石露头最多50米，而在第二个区域，房屋距离岩石露头至少200米。埃及伊蚊在后者区域明显更为丰富。研究发现，即使有更多潜在繁殖场所，带有本地凤梨科植物的岩石露头作为埃及伊蚊的繁殖场所并不起重要作用。这一结论支持了以下假设，即本地凤梨科植物的微生物群落在埃及伊蚊的自然控制中发挥着重要作用。此外，蚊子物种之间的种间竞争以及凤梨科植物的吸引力也可能是重要因素。
