苏里南和法属圭亚那之间的边界地区被认为是南美洲受疟疾影响最严重的地区。2004年3月至2005年2月，两国在四个村庄进行了为期一年的疟疾病媒合作研究。达令按蚊是种类最多的按蚊。不同村庄的咬人率不同。高降雨量对村庄蚊子密度的不同影响表明滋生地点的差异。总的产次比率很低，每个研究地点的平均数从0.31到0.56不等。在采集的2045只达令氏按蚊中，发现13只感染了疟疾：10只恶性疟原虫，2只恶性疟原虫，1只混合间日疟原虫。全村年昆虫学接种率为8.7%~66.4%。疟疾病例数与蚊虫密度高发期之间明显缺乏联系。达林伊按蚊在睡觉时间咬人的倾向为使用浸渍蚊帐控制疟疾提供了机会，这是苏里南刚刚引入的一种策略，也可能进入法属圭亚那。(C)2009年皇家热带医学和卫生学会。爱思唯尔有限公司出版。保留所有权利。
The border area between Suriname and French Guiana is considered the most affected malaria area in South America. A one-year cooperative malaria vector study was performed by the two countries, between March 2004 and February 2005, in four villages. Anopheles darlingi proved to be the most abundant anopheline species. Human biting rates differed between villages. The differential effect of high rainfall on mosquito densities in the villages suggests variation in breeding sites. Overall parity rates were low, with means varying from 0.31 to 0.56 per study site. Of the 2045 A. darlingi mosquitoes collected, 13 were found to be infected with Plasmodium: ten P. falciparum, two P. malariae and one mixed P. malariae/P. vivax. The overall annual entomological inoculation rates in the villages ranged from 8.7 to 66.4. There was an apparent lack of relationship between number of malaria cases and periods of high mosquito density. The tendency of Anopheles darlingi to bite during sleeping hours provides opportunity for malaria control using impregnated bed nets, a strategy just introduced in Suriname that may also find its way into French Guiana.
