“…The Instituto de Investigaciones Biológicas del Trópico conducted an investigation for the surveillance of alphaviruses in mosquitoes in three areas of Córdoba between August 2012 and January 2013, in which Psorofora confinnis were captured, one of the most important species in the epizootic cycle of the VEEV (Ferro et al, 2015), as well as the species Mansonia indubitans, Culex quinquefasciatus, Mansonia titillans, all these species are related to transmission of epizootic strains IAB, VEEV IC (Acha and Szyfres, 2003;Mesa et al, 2005). The species C. nigripalpus, Aedes scapularis, C. vomerifer, C. panocossa, which have been involved in the Americas with the maintenance of enzootic VEEV strains, were also captured during that entomological surveillance.…”

Objective: To study the eco-epidemiology of alphaviruses in bats of departments of Córdoba and Sucre, Colombia. Methodology: A prospective descriptive cross-sectional study with a non-probabilistic sampling, in 12 localities of Córdoba and Sucre was carried out. Using mist nets capture of the specimens was carried out. The size of the sample was 286 bats, each specimen captured was taxonomically classified. The bats were immobilized with anesthetic and analgesic treatment according to the ethics committee of the University of Córdoba, morphometric measurements and blood samples were taken, later they were necropsied in the field to obtain a collection of tissues which were preserved in liquid N 2 −190°C. The averages of the climatic conditions of the sampling sites were extracted from the WorldClim database (http://www.worldclim.org/). The open source software QGIS (Quantum GIS Development Team.2015) was used to map and visualize bioclimatic regions of Córdoba. We used descriptive and retrospective information about the equine population and reports of foci of equine encephalitis. Results: In Córdoba and Sucre, 286 bats were captured and 23 species were classified, Artibeus and Phyllostomus discolor were the most frequent captured genus. The geographic ranges of the captured species were variable, some had a wide distribution and others were restricted to some areas. Venezuelan equine encephalitis virus RNA was detected in Artibeus planirostris and Sturnira lilium (2/286 = 0.70%) from Cordoba -Colombia. The univariate descriptive analysis showed no significant association for any of the analyzed variables climatic. Conclusions: Frugivorous bats from the Caribbean area of Colombia may be involved in the Venezuelan equine encephalitis virus enzootic cycle.

“…In South America the MAYV is considered arthrogenic. The reemergence of CHIKV reiterates the potential threat posed by alphaviruses to human health, and the need to understand mechanisms involved in their biology (Simon et al, 2006;Ferro et al, 2015). Many of these viruses circulate permanently in an enzootic cycle that involves wild animals that live in nearby environments where anthropic activities take place.…”

“…Aedes aegypti (Diptera: Culicidae) es un vector de gran importancia en la salud pública en regiones tropicales y subtropicales, relacionado con la transmisión de diversas enfermedades, principalmente arbovirosis (Gómez, 2018), donde resaltan el dengue, chikungunya, zika y la fiebre amarilla (OPS, 2022). Adicionalmente, se ha sugerido su papel como vector potencial del virus de la encefalitis equina venezolana (Ferro et al, 2015), el virus mayaro (Huancas de la Cruz et al, 2019) y estudios de competencia vectorial in vitro han mostrado que es también susceptible al virus del occidente del Nilo (Gómez, 2018). Comprender el papel vectorial de Ae.…”

Finding alternatives for the control of Aedes aegypti transmitter of various arboviral diseases is essential in public health. As an objective, it was proposed to determine the effectiveness of repellency and protection time of soaps based on natural essences against Ae. aegypti. The study was descriptive-experimental. Three soaps made with 20% of the extract + Neutral liquid soap (Mentha piperita L, Lavandula angustifolia) and one mixed (Lavandula angustifolia + Vanilla planifolia) were studied, as a positive control commercial repellent OFF (20% DEET) and 70% alcohol were used. % as Negative Control. The mosquito population used was 50 females of Aedes aegypti (New Orleans strain), the volunteers were 5 men between 25-35 years old. The data was stored in Microsoft Excel and processed with SPSS, Percentage repellency (PRp), Percentage protection (PP) or repellent efficiency and bites/day were calculated. As a result, the (PP) of the Mint soap was 100% at min1, 12% at min60 and 25% at min120, the Lavender soap had 100% protection at min1, 72% at min60 and 20% at at min120, the Lavender+Vanilla soap had a % repellency of 100% at min 1, 99% at min 60 and 87% at min 120. In conclusion, the findings of this study suggest the possibility of replacing synthetic repellents with repellents with essences extracted from plants, however, it is essential to continue with research in various areas of Peru where cases of dengue, Zika and Chikungunya are increasing.
