Four species within the Anopheles punctulatus group of mosquitoes (Diptera: Culicidae) were identified by allozyme analysis of samples collected from thirty-three localities in Guadalcanal, Makira, Malaita, Temotu and Western Provinces in the Solomon Islands and six localities on Efate, Espiritu Santo, Maewo and Malekula Islands in Vanuatu. Three of these species are members of the An.farauti complex. A key is given to identify five species of the An.punctulatus group known to occur in the Solomon Islands using their isoenzyme characteristics. An.farauti No. 1 was widespread in coastal areas of the Solomon Islands and was the only species detected in Vanuatu, including Efate Island (where Faureville is the type locality of An.farauti Laveran sensu stricto). An.farauti No. 2 and An.punctulatus were common in the Solomon Islands in more inland areas. An.farauti No. 7, reported here for the first time, was found as larvae in freshwater at six localities on north Guadalcanal. Three other members of the An.punctulatus group which have been reported previously from the Solomon Islands: An.koliensis, An.renellensis and an electrophoretic variant of An.farauti sensu lato, were not found in our samples. Previously recognized vectors of malaria and bancroftian filariasis in the Solomon Islands are An.farauti No. 1 (i.e. An.farauti s.s.), An.koliensis and An.punctulatus s.s. Adult females of An.farauti No. 2 and An.farauti No. 7 were not attracted to human bait in areas where their larvae occurred, indicating that these two species are not anthropophilic and therefore unlikely to transmit human pathogens.
通过对从所罗门群岛瓜达尔卡纳尔岛、马基拉岛、马莱塔岛、泰莫图省和西部省的33个地点以及瓦努阿图埃法特岛、圣埃斯皮里图岛、马埃沃岛和马列库拉岛的6个地点采集的样本进行等位酶分析，鉴定出了按蚊属斑点按蚊组（双翅目：蚊科）中的4个物种。其中3个物种是法劳按蚊复合体的成员。给出了一个检索表，用于根据同工酶特征鉴定已知在所罗门群岛出现的5种斑点按蚊组物种。法劳按蚊1号在所罗门群岛沿海地区广泛分布，是在瓦努阿图检测到的唯一物种，包括埃法特岛（法勒维尔是狭义法劳按蚊的模式产地）。法劳按蚊2号和斑点按蚊在所罗门群岛更多的内陆地区很常见。本文首次报道的法劳按蚊7号，在瓜达尔卡纳尔岛北部的6个地点的淡水中发现其幼虫。此前报道来自所罗门群岛的斑点按蚊组的其他3个成员：科利按蚊、伦内尔按蚊和广义法劳按蚊的一个电泳变体，在我们的样本中未被发现。所罗门群岛先前确认的疟疾和班氏丝虫病媒介是法劳按蚊1号（即狭义法劳按蚊）、科利按蚊和狭义斑点按蚊。法劳按蚊2号和法劳按蚊7号的成年雌性在其幼虫出现的地区未被人饵吸引，这表明这两个物种不是嗜人血的，因此不太可能传播人类病原体。
