Bionomics of Anopheles gambiae complex (Diptera: Culicidae) and malaria transmission pattern in a pre-elimination area in South-Western Senegal.
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 2 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
backgroundMalaria remains a public health problem in many African countries. In Senegal, the Southern region had the highest malaria incidence and malaria-related deaths. The relationship between vector density and malaria transmission remains poorly understood in some specific areas. The aim of this study was to characterize the current entomological and transmission parameters with special emphasis on the Anopheles gambiae complex in the malaria pre-elimination area of Mlomp south-western Senegal.
methodsThe study was conducted from July 2020 to February 2021 in Djicomol and Cadjinolle in the commune of Mlomp region of Ziguinchor, Senegal. Sampling was carried out using Human Landing Catches (HLC) and Pyrethrum Spray Catches (PSC). Ovaries were dissected to determine female parity rate. Infection status, blood meal sources and species molecular identification were determined using Enzyme-Linked Immunosorbent Assay (ELISA) and Polymerase Chain Reaction (PCR) techniques respectively.
resultsA total of 6956 mosquitoes of the An. gambiae complex were collected, of which 6739 were by HLC (96.88%) and 217 by PSC (3.12%). The mean human biting rate was 36.98 bites/person/night (b/p/n) indoors and 43.25 b/p/n outdoors. Female biting activity was more frequent during the second half of the night. Mean parity rates were 24.83% indoors and 18.94% outdoors. The human blood index was estimated at 76.09%. Overall, An. gambiae sensu stricto (s.s.) was the most common species (75.08%). No female An. gambiae was found to be infected with Plasmodium falciparum in the sub-sample tested, thus no malaria transmission was recorded in Mlomp during the study period.
conclusionsThe results alert malaria control programme to develop additional strategies for controlling these vectors, which show exophagic behaviours to effectively combat malaria.
