Anopheles longipalpis (Theobald) (Diptera: Culicidae) is a predominantly zoophilic mosquito that has not been implicated in malaria transmission. However, this species was collected indoors with An. funestus s.l. in southern Zambia, where transmission of Plasmodium falciparum is hyperendemic, and we initially misidentified it morphologically and molecularly as An. funestus s.l. The indoor resting density and blood-feeding behaviour of An. longipalpis were investigated during the 2004-05 and 2005-06 transmission seasons in Mufwafwi village in southern Zambia. Numbers of endophilic An. longipalpis increased towards the end of the rainy season. Although specimens were collected during human landing catches, the feeding behaviour of An. longipalpis was significantly biased towards cattle (88.7%), with other bloodmeals originating from dogs, goats and chickens. None of the 177 specimens of An. longipalpis were infected with P. falciparum. These data are consistent with existing reports that An. longipalpis is not involved in malaria transmission. However, more extensive sampling is necessary. Importantly, the correct identification of An. longipalpis is crucial for malaria control programmes in areas where An. funestus s.l and An. longipalpis exist sympatrically so that scarce resources are not wasted on the control of a non-vector.
长须按蚊（Theobald）（双翅目：蚊科）是一种主要嗜动物血的蚊子，尚未发现其参与疟疾传播。然而，在赞比亚南部恶性疟原虫传播高度流行的地区，该物种与嗜人按蚊复合组一同在室内被采集到，我们最初在形态学和分子学上都将其误鉴定为嗜人按蚊复合组。在赞比亚南部穆夫瓦夫伊村2004 - 05年和2005 - 06年传播季节期间，对长须按蚊的室内栖息密度和吸血行为进行了调查。嗜室内栖息的长须按蚊数量在雨季末期增加。尽管在人饵诱捕期间采集到了标本，但长须按蚊的吸血行为明显偏向于牛（88.7%），其他血餐来源为狗、山羊和鸡。177只长须按蚊标本均未感染恶性疟原虫。这些数据与现有报道一致，即长须按蚊不参与疟疾传播。然而，需要进行更广泛的采样。重要的是，在嗜人按蚊复合组和长须按蚊同域存在的地区，正确鉴定长须按蚊对于疟疾控制项目至关重要，这样就不会将稀缺资源浪费在控制一种非传播媒介上。
