On Tereia Island, Rangiroa Atoll, 14,321 land crab burrows were treated with the copepod Mesocyclops aspericornis from January to June 1986, to control larvae of Aedes polynesiensis marks. In October 1987, the entire island of Tereia was retreated (17,300 burrows), and the neighboring island, Voisin, was left untreated as a control. From 5 to 15 mo after treatment, burrows with M. aspericornis contained an average of 2 Ae. polynesiensis immatures compared with 97 immatures from untreated burrows. Long-term larval control was successful in low-lying areas where burrows remained wet or were reflooded. Although there may have been other contributing factors, the major reason for lack of persistence of M. aspericornis in burrows over the entire island appeared to be poor resistance to desiccation. From all treated burrows in October 1987, M. aspericornis subsequently was found in 89.5, 39.1, and 24.1% of burrows sampled 5, 8, and 15 mo after treatment, respectively. The broad-scale results for Tereia indicated that there was no reduction of adult biting indices when compared with Voisin. Mark-release experiments on four occasions indicated that Ae. polynesiensis had a limited flight range and that the probability for interisland movement was low.
1986年1月至6月期间，在朗伊罗阿环礁的泰雷亚岛上，对14321个陆地蟹洞穴用挠足类动物粗糙中剑水蚤进行处理，以控制波利尼西亚伊蚊幼虫。1987年10月，泰雷亚岛全岛再次进行处理（17300个洞穴），而邻近的瓦赞岛未作处理作为对照。处理后5至15个月，有粗糙中剑水蚤的洞穴平均有2只波利尼西亚伊蚊未成熟个体，而未处理的洞穴有97只未成熟个体。在地势低洼、洞穴保持湿润或再次被水淹没的地区，长期幼虫控制取得成功。尽管可能还有其他促成因素，但粗糙中剑水蚤在全岛洞穴中难以持久存在的主要原因似乎是对干燥的抵抗力较差。在1987年10月所有处理过的洞穴中，处理后5、8和15个月分别在89.5%、39.1%和24.1%的采样洞穴中发现了粗糙中剑水蚤。泰雷亚岛的大规模结果表明，与瓦赞岛相比，成蚊叮咬指数没有降低。四次标记释放实验表明，波利尼西亚伊蚊飞行范围有限，岛屿间移动的可能性较低。
