Anopheles mosquitoes in Mondulkiri forest, Cambodia: abundance, distribution, seasonal patterns and Plasmodium prevalence.
Article in Malaria journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMosquitoes are important drivers of infectious diseases transmission, with Anopheles mosquitoes being responsible of malaria transmission. In Cambodia, where malaria is prevalent in forested regions, understanding the ecology of these vectors is crucial. This study aimed to investigate the abundance, distribution, seasonal patterns, biting behaviour of Anopheles mosquitoes, and prevalence of Plasmodium, in Mondulkiri province, Northeastern Cambodia.
methodsConducted in 9 sites, seven in forested and two in neighbouring villages, over one year, the collection of Anopheles mosquitoes was made hourly for a 72-h period every month, using a human-baited double net trap. Each mosquito was collected using a mouth-aspirator and identified morphologically, and screened for the presence of Plasmodium.
resultsPrimary vectors, including Anopheles baimaii, Anopheles dirus, Anopheles maculatus, and Anopheles minimus, constituted 11.1% of all female mosquitoes, while 12 secondary vector species represented 29.4% of the overall collection. Anopheles species were more prevalent during the late rainy season (August to November), with year-round activity observed. Primary vectors were predominantly found in forest sites, while other vector species were found in both village and forest environments. Notably, primary vectors exhibited a preference for nocturnal biting, yet a significant proportion (19.2%) displayed daytime activity, highlighting a potential risk of daytime malaria transmission. Among 5,056 Anopheles specimens tested, only 36 Plasmodium spp.-infected samples were detected, mainly in forest sites (94%), and in specimens collected at night. This study provides essential insights into the ecology of Anopheles in Mondulkiri Forest.
conclusionsThe identification of primary and secondary vectors, their seasonal dynamics, and biting behaviour contribute to enhances our understanding of malaria transmission risks in these areas, guiding future strategies toward effective and context-specific control measures, while stressing the need for individual protection during daytime.
