“…This is particularly relevant to this region because mosquito-borne diseases, including dengue virus, impose a substantial public health burden. Aedes aegypti is considered the primary dengue vector in Costa Rica, but the ongoing, patchily described invasion by the globally important vector species Aedes albopictus is potentially reshaping disease risk (Troyo et al ., 2006; Calderon-Arguedas et al ., 2010; Calderón-Arguedas et al ., 2015; Rojas-Araya et al ., 2017). Finally, a pioneering national Payment for Ecosystem Services program offers a well-established venue for translating research findings into land management policy, and evidence for additional ecological and human health benefits of local tree cover may help motivate enforcement of an existing law that protects riparian buffer zones up to 50m around rivers, which is expected to increase access to clean water for vulnerable populations, and pertains to a spatial scale at which tree cover has previously been shown to protect biodiversity for other taxa (Sánchez-Azofeifa et al ., 2007; Langhans et al ., 2022).…”

Land use change is an important driver of both biodiversity loss and zoonotic disease transmission in tropical countryside landscapes. Developing solutions for protecting biodiversity, public health, and livelihoods in working landscapes requires understanding the spatial scales at which habitat characteristics such as land cover shape biodiversity, especially for arthropods that transmit pathogens. A growing body of evidence shows that species richness for many taxa correlates with tree cover at small spatial scales of <100 m, indicating that local tree cover management is a promising conservation tool. To investigate whether mosquito species richness, community composition, and presence of specific disease vector species respond to tree cover— and if so, whether at spatial scales similar to other taxa—we surveyed mosquito communities along a tree cover gradient and across agricultural, residential, and forested land uses in rural southern Costa Rica. We found that tree cover was both positively correlated with mosquito species richness and negatively correlated with the presence of the common invasive dengue vectorAedes albopictus, particularly at small spatial scales of 80 – 200m. Beyond tree cover, land use type predicted community composition andAe. albopictuspresence, but not species richness. The results suggest that preservation and expansion of tree cover at local scales can protect biodiversity for a wide range of taxa and also confer protection against disease vector occurrence.

“…More recently, mosquito blood feeding patterns from several species were described at Lomas Barbudal, a wetland near Cuajiniquil (CU) in Costa Rica (21). Aside from these, more recent mosquito research in Costa Rica has focused mostly on primary vectors of Dengue (DENV), Zika (ZIKV) and chikungunya (CHIKV) viruses, Aedes aegypti and Aedes albopictus (22)(23)(24), due to their importance in public health.…”

Mosquitoes are vectors of several arboviruses belonging to the genus Alphavirus and Flavivirus. Costa Rica is endemic for several arboviruses. To described and analyze the community structure of vectors in the country, a sampling was performed in two different coastal locations with evidence of arboviral activity during rainy and dry seasons. Encephalitis vector surveillance Traps, CDC Female Gravid Traps and ovitraps were used. Viral detection for several arbovirus was attempted. Blood-meal identification was also performed. A total of 1802 adult mosquitoes belonging to 55 species were captured. Culex quinquefasciatus was the most captured. species The Normalized Difference Vegetation Index (NDVI) was estimated for each area during rainy and dry season. The higher difference between seasonal regional NDVI yield lower values of Chao- Sørensen Similarity Index. Chao2 values and Shannon Index for species diversity were also estimated. There was no viral detection for VEEV, WNV, Madariaga. Dengue virus and Zika virus were detected in two separate Culex quinquefasciatus. The main sources of bloodmeal chickens (60%) and humans (27.5%). Both sampled areas have different seasonal dynamics and population turnover reflected in the Chao2 species richness estimation values and Shannon diversity Index. NDVI influence the mosquito diversity at a regional scale more than at a local scale. However, yearlong continuous sampling is required for a better understanding of local dynamics.

Objetivo: Evaluar, bajo una perspectiva ecológica, la presencia de Aedes albopictus y su infección natural por virus dengue (DENV) en una zona de actividad piñera de Costa Rica.Métodos: Se colectaron mosquitos adultos en galerías forestales colindantes con piñeras, viviendas en proximidad a cultivos (<1 Km) y viviendas en lejanía (1-10 Km). Se empleó el índice de Shannon-Wiener para estimar biodiversidad. La infestación larvaria se evaluó en plantas de piña y viviendas, y se calcularon índices aédicos de viviendas (IV) y contenedores (IC). Mediante RT-PCR y secuenciación, se detectó DENV en adultos (cuerpos y cabezas) y larvas de Ae. albopictus.Resultados: Se colectaron 1376 adultos en total: Ae. albopictus (5,81%), Anopheles apicimacula (5,01%), Culex coronator (11,55%), Cx. inflictus (6,1%), Cx. nigripalpus (48,11%), Cx. quinquefasciatus (23,34%) y Limatus durhamii (0,07%). El índice de biodiversidad fue mayor en galerías forestales. Ae. albopictus adultos fueron colectados principalmente en el área de piñeras (73/80), aunque sólo 2 larvas en las plantas de piña. Los índices aédicos en proximidad (IV: 40,7%, IC: 26,9) y en lejanía (IV: 51,7%, IC: 29,6%) no mostraron diferencias (IV Z=0,56, p=0,58; IC Z=0,16, p=0,87). Se detectó DENV-2 y DENV-3 en 2/20 “pooles” de cabezas y DENV-1 en 2/74 “pooles” de larvas de Ae. albopictus.Discusión: Las galerías forestales próximas a cultivos de piña podrían considerarse “islas ecológicas” adecuadas para el refugio de Ae. albopictus. La presencia de DENV en adultos y larvas sugiere un papel activo de Ae. albopictus en la transmisión en este ecosistema.
