“…In the case of yellow fever, Haemagogus spegazzinii was identi ed as the possible vector during an outbreak in Costa Rica in 1953 (20). 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.

Background Mosquitoes are vectors of various arboviruses belonging to the genera Alphavirus and Flavivirus, and Costa Rica is endemic to several of them. The aim of this study was to describe and analyze the community structure of such vectors in Costa Rica. Methods Sampling was performed in two different coastal locations of Costa Rica with evidence of arboviral activity during rainy and dry seasons. Encephalitis vector surveillance traps, CDC female gravid traps and ovitraps were used. Detection of several arboviruses by Pan-Alpha and Pan-Flavi PCR was attempted. Blood meals were also identified. The Normalized Difference Vegetation Index (NDVI) was estimated for each area during the rainy and dry seasons. The Chao2 values for abundance and Shannon index for species diversity were also estimated. Results A total of 1802 adult mosquitoes belonging to 55 species were captured, among which Culex quinquefasciatus was the most caught species. The differences in NDVI were higher between seasons and between regions, yielding lower Chao-Sørensen similarity index values. Venezuelan equine encephalitis virus, West Nile virus and Madariaga virus were not detected at all, and dengue virus and Zika virus were detected in two separate Cx. quinquefasciatus specimens. The primary blood-meal sources were chickens (60%) and humans (27.5%). Both sampled areas were found to have different seasonal dynamics and population turnover, as reflected in the Chao2 species richness estimation values and Shannon diversity index. Conclusion Seasonal patterns in mosquito community dynamics in coastal areas of Costa Rica have strong differences despite a geographical proximity. The NDVI influences mosquito diversity at the regional scale more than at the local scale. However, year-long continuous sampling is required to better understand local dynamics. Graphical Abstract
