The Culicoides (Diptera: Ceratopogonidae) of Arkansas: a species checklist and comparison of diversity across ecoregions and habitats.
Article in Journal of medical entomology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Culicoides biting midges (Diptera: Ceratopogonidae) are globally distributed hematophagous flies. They transmit arboviruses to wild and domestic ruminants, such as cattle, sheep, and white-tailed deer. Despite their importance in pathogen transmission, most work characterizing diversity and distribution in the United States has focused on the western United States and Florida. This study aimed to determine Culicoides species composition and distribution across Arkansas over a 3-yr trapping period (2022 to 2024). Culicoides were collected from the seven ecoregions within Arkansas at agricultural and natural areas. CDC-UV miniature light traps were set in May, July, and August/September/October for 5 consecutive nights at each study site. In total, 9,510 midges were collected, representing 15 species. The Ozark Highlands/Boston Mountains ecoregion had the highest abundance of Culicoides, and the collection was primarily composed of Culicoides biguttatus (Coquillett). The Arkansas Valley ecoregion was the most diverse, and the community composition between the agricultural and natural sites was similar. Parous females were tested for bluetongue virus and epizootic hemorrhagic disease virus using qRT-PCR; however, no positive pools were found. This study represents the first attempt to comprehensively describe the diversity of Culicoides in Arkansas. Future work should aim to continue collecting Culicoides across the state and testing them for pathogens.
