在印度西南部、斯里兰卡和东南亚，7种疟疾自然感染8种猕猴。在疟疾流行地区，受感染猕猴的感染频率从9%到61%不等。猕猴的自然疟疾感染是相对良性的。猕猴疟疾的已证实或可能的媒介是属于按蚊属Leucosphyrus组的七种蚊子。猕猴疟疾的地理分布显然是由白腹蚊群的分布决定的，而白腹蚊群的分布又显然是由热带万年青雨林的分布决定的。实验性感染三种猕猴疟疾，对于居住在寄生虫地理范围以外地区的猕猴种群或种属来说，往往是致命的。在与实验上的疟疾毒力种同域分布的猕猴种群或种中，部分抗性可能是自然选择作用于有利突变的结果。
Seven species of malaria naturally infect eight species of macaques in southwestern India, Sri Lanka, and Southeast Asia. Within malarious areas, the frequency of infections in infected species of macaques varies from 9 to 61%. Natural malarial infections in macaques are relatively benign. The proved or probable vectors of macaque malaria are seven species of mosquitoes that belong to the Leucosphyrus Group of the genus Anopheles. The geographic distribution of macaque malaria apparently is determined by the distribution of the Leucosphyrus Group of mosquitoes, which in turn apparently is determined by the distribution of tropical evergreen rain forest. Experimental infections with three species of macaque malaria frequently are lethal to populations or species of macaques that inhabit areas outside the geographic ranges of the parasites. In populations or species of macaques that are sympatric with experimentally virulent species of malaria, partial resistance probably evolved as a consequence of natural selection acting on favorable mutations.
