Adult female mosquitoes were collected in Mahdia, Guyana, to determine the incidence of malaria in Anopheles species found during the month of June 2000. Centers for Disease Control miniature white (incandescent) light traps, model 512, and miniature black (ultraviolet) light traps, model 912, were used to capture female mosquitoes. Numbers of mosquitoes collected were compared between white and black light traps and between traps set outside and inside of buildings. Adult female Anopheles mosquitoes were identified and an ELISA dipstick test for Plasmodium vivax and Plasmodium falciparum was performed on each mosquito. An aquasalis, An oswaldoi, and An braziliensis were attracted to white light traps. An triannulatus and An darlingi were collected from black light traps. Approximately the same numbers of all female Anopheles mosquitoes 28/45 (62%) were caught inside buildings as outside. Numbers of female non-anopheles mosquitoes captured in light traps varied between the traps set outside of buildings and inside of buildings with bright light traps collecting 91/122 (75%). A total of 45 Anopheles mosquitoes were captured and 122 non-anopheles species. Of the two known vectors of malaria in Guyana, An darlingi mosquitoes were not infected with P vivax but An aquasalis was found to be a carrier. The findings of this study suggest a need for further surveying and identification of current malaria vectors in Guyana.
在圭亚那的马赫迪亚收集成年雌性蚊子，以确定2000年6月发现的按蚊种类中疟疾的发病率。使用疾病控制中心的512型微型白色（白炽灯）诱蚊灯和912型微型黑色（紫外线）诱蚊灯捕捉雌性蚊子。比较了白色和黑色诱蚊灯以及设置在建筑物内外的诱蚊灯捕获的蚊子数量。对捕获的成年雌性按蚊进行鉴定，并对每只蚊子进行间日疟原虫和恶性疟原虫的ELISA试纸检测。嗜人按蚊、奥斯瓦尔多按蚊和巴西按蚊被白色诱蚊灯吸引。环纹按蚊和达林按蚊是从黑色诱蚊灯中收集到的。在建筑物内和建筑物外捕获的所有雌性按蚊数量大致相同，为28/45（62%）。在建筑物外和建筑物内明亮的诱蚊灯中捕获的非按蚊雌性蚊子数量有所不同，明亮诱蚊灯捕获了91/122（75%）。总共捕获了45只按蚊和122只非按蚊。在圭亚那已知的两种疟疾传播媒介中，达林按蚊未感染间日疟原虫，但发现嗜人按蚊是携带者。这项研究的结果表明，需要对圭亚那目前的疟疾传播媒介进行进一步的调查和鉴定。
