Preliminary data on the vector competence of Aedes caspius for Dirofililaria immitis in a traditionally endemic area of northern Italy.
Article in Parasites & vectors, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 4 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
backgroundDirofilaria immitis, the agent of canine and feline heartworm disease, and Dirofilaria repens, the agent of subcutaneous dirofilariosis, are widespread mosquito-borne helminths. The present study is aimed at updating current knowledge of the composition of potential vector species in the northern region of Emilia-Romagna, a traditionally endemic area for D. immitis and D. repens.
methodsMosquitoes were collected in 2022 and 2023 as part of the regional surveillance plan for West Nile Virus (WNV). The capture zones included peri-urban and rural areas and mosquitoes were captured with CDC-CO
resultsA total of 140 pools (~ 20 mosquitoes each) in 2022 and 133 in 2023 have been analyzed. DNA of D. immitis was identified in 14 pools in 2022 and in 15 pools in 2023. None of the pools was positive for D. repens. In 2022, about 85% of the positive pools belonged to Ae. caspius species (11/13) and the other three pools to Ae. vexans. In 2023, 73% of the positive pools belonged to Ae. caspius, followed by Ae. vexans and Ae. albopictus (both 13.3%). A significant overlap emerged from the same traps positioned in Ferrara and Bologna provinces, which tested positive for D. immitis in both 2022 and 2023.
conclusionsThese data highlight how, despite the abundance of Cx. pipiens captured, the most receptive species for D. immitis appear to be Ae. caspius and Ae. vexans. Furthermore, the geographical data highlights how the areas of the province of Ferrara and Bologna are the main geographical reservoirs of the parasite.
