巴西疟疾的主要媒介是达林伊按蚊。Aquasalis，以及一些种类的An.复杂的白化病，而其他的在疾病传播方面的重要性值得怀疑。为了在巴西帕拉州恶性疟原虫高流行地区识别这些媒介，捕获并鉴定了565条按蚊，同时测定了季节变化和每日叮咬活动。在7种按蚊中(An.Strodei，An.Albitarsis s.l，An.Rondoni，An.亲爱的，安。Triannulatus，An.Oswaldoi和An.其中3例检出环子孢子蛋白(CSP)，总感染率为6.2%。一种。最常见的种类是大林木(22.4%)，其次是An。白化病(5.2%)和An.隆多尼(3.6%)。一种。隆多尼是第一次被发现感染，这一点也通过PCR得到了确认。这一结果可能代表了一种新的疟疾媒介，基于其在疟疾传播高峰期的最高频率、叮咬和季节性活动。
The main vectors of malaria in Brazil are Anopheles darlingi, An. aquasalis, and some species of the An. albitarsis complex, whereas others have questionable importance with regard to the disease transmission. To identify these vectors in the State of Para, Brazil, in a high-prevalence P. falciparum area, 565 anophelines were captured and identified while the seasonal variation and daily biting activity were determined. Of the seven anopheline species (An. strodei, An. albitarsis s.l., An. rondoni, An. darlingi, An. triannulatus, An. oswaldoi, and An. nuneztovari), the plasmodia circumsporozoite protein (CSP) was detected in three of them, with a total infection rate of 6.2%. An. darlingi was the most prevalent species (22.4%), followed by An. albitarsis (5.2%) and An. rondoni (3.6%). An. rondoni was found to be infected for the first time, which was also confirmed through PCR. This result possibly represents a new malaria vector based on its highest frequency, biting and seasonal activities in the peak of malaria transmission.
