title: Preliminary studies of Anopheles mosquitos in eight provinces in Lao PDR.
abstract: Malaria vector surveys were carried out in 8 provinces in Lao PDR in 1999. The surveys were conducted in 4 provinces - Savannakhet, Champasak, Luang Perbang and Sayaboury in May and in another 4 provinces - Bolikhamsay, Sarvan, Sekong and Vientiane in December 1999. Bare leg collection were carried out indoors and outdoors from 6 pm to 5 am. All anopheline mosquitos were identified, dissected and the gut, gland and ovaries were examined. A total of 438 Anopheles mosquitos belonging to 19 species were obtained. Of these only 3 species were found to be infected with oocysts - An. maculatus, An. dirus and An. minimus. All these species were found biting both indoors and outdoors. An. aconitus was the predominant species obtained in the December collection but its vectorial status remains unknown.
