In remote areas with endemic and vulnerable indigenous population, it is necessary to implement measures that help to offset the increase of malaria, in addition to theearly diagnosis, treatment and vector control. Here, we evaluate a classroom project to change levels of knowledge, attitudes and practices (KAP) in relation to the prevention and control of malaria in amerindian school population of primary level. We carried out a quantitative assessment, under a quasi-experimental "before and after" design, with children from 3rd and 4th grades in five Ye'kwana communities inthe Caura River Basin (Bolivar State, Venezuela). According to previously informed community consent, intercultural bilingual teachers performed and evaluated results of the educational intervention using a questionnaire on knowledge, attitudes and practices translated into Ye'kwana language. Intervention data were analyzed by Wilcoxon signed pairedtests. We compared differences between before intervention (T1), immediately after (T2), and also some time afterthe intervention (T3 = 45-60 days).In the T1-T3 interval significant improvements (P<0.05) were recorded in all questions of knowledge and a positive, non-significant changes in all attitude questions. Changes in practices for malaria prevention were mixed.The results show thepotentialforthe classroom-teaching project tested toassist in the prevention and control of malaria at indigenous community schools.

Anopheles albitarsis F and Anopheles oswaldoi B were first recorded from collections in Sucre and Cedeño Municipalities, Bolivar State. Morphometric analysis of dark and pale spots on wing Costa and hind tarsomeres of adult females, showed that the range of variation for An. albitarsis F are within the reported ranges for An. marajoara sensu latu For An. oswaldoi B the range of variation are within the ranges reported for An. oswaldoi s.l., An. oswaldoi sensu stricto from Brazil and An. konderi. DNA mitochondrial analysis (Barcode region 658 bp) showed 3.2% of genetic divergence between An. oswaldoi B and An. oswaldoi s.s., while this divergence was 5.2% between An. albirtarsis F and An. marajoara s.s. Both these values are above the proposed limits for species delimitation. Source

This is the first report of anophelines and culicines species in the indigenous territory of the Lower Caura River, Bolívar State. A total of 8 species of anophelines belonging to the subgenus Anopheles Meigen, Lophopodomyia Antunes, Stethomyia Theobald, Nyssorhynchus Blanchard of the genus Anopheles Meigen and Chagasia bathana Dyar and 10 genera of culicines were collected and 7 species identified. Larval habitats were identified and characterized based on the hidrology in stream, small river, spring, lagoon, swamp and pool. Culicines were also collected in artificial and natural containers. The most abundant species in collections of inmature stages was Anopheles triannulatus (Neiva & Pinto), while in adult collections on human landing catches and CDC light traps the most abundant species was the malaria vector An. darling Root. Ultra violet up draft light traps were inefficient to collect anophelines and culicines. It is reported for the first time the presence in Bolívar State of the genus Coquillettidia Dyar and Johnbelkinia Zavortink, and the species Aedes (Ochlerotatus) fulvus (Wiedemann) and Ae. (Och.) serratus (Theobald). Source

Adaptive management and ecohealth frameworks were developed for malaria elimination in Amerindian riparian communities of Venezuela. These frameworks were developed as a strategy to capture, organize, and communicate connections among key factors related to local malaria complex systems. Important causal relationships between social, economic, and environmental stressors which are determinant of malaria were identified at different levels and assumptions that guide interventions are offered, based on available scientific knowledge and input from stakeholders. Drawing on our experience of action research committed to the health of Amerindian populations and conservation of areas with biodiversity value, the authors provide lessons to strengthen the practice of an ecohealth approach. First, conservation targets were considered as a way to achieve sustainable human well-being rather than as a consequence of well-being. Second, the effectiveness and sustainability of technical solutions generally proposed for malaria control depend largely on individual knowledge, attitudes, and practices. Hence, it is necessary to look at the real opportunities of choices that Amerindian people have for attaining a life without malaria, and therefore pay attention to local capabilities, needs, and freedom to choose. The ecohealth approach can benefit from the capability approach, and we explain why. © 2015, International Association for Ecology and Health. Source

Aedes aegypti (L.) is first recorded from a remote area in the amerindian territory of the Erebato river basin, Sucre Municipality, Bolívar State. One specimen was collected during the malaria entomological surveillance using the Mosquito Magnet™ trap between 21:30 and 01:30 hrs. This finding alerts about the risk of the introduction of Ae. aegypti in selvatic remote areas and subsequent introduction of dengue, which might have a major health impact among the amerindian population.
