Chagas' disease: Risk factors for house infestation by Triatoma dimidiata, the major vector of Trypanosoma cruzi in Costa Rica
(The Johns Hopkins University School of Hygiene and Public Health., 1991)The reduction of domiciliary infestation by insect vectors, the key to controlling Chagas' disease, depends on identification of housing features associated with infestation. In this study, log-linear modeling was used to ... -
Changes in Phlebotomine Sand Fly Species Composition Following Insecticide Thermal Fogging in a Rural Setting of Western Panamá
(PLOS ONE, 2013-01-09)American Cutaneous Leishmaniasis, ACL, is a zoonotic disease with a large richness of co-occurring vector species in transmission foci. Here, we describe changes in patterns of phlebotomine sand fly (Diptera: Psychodidae: ... -
Climatic variability and landscape heterogeneity impact urban mosquito diversity and vector abundance and infection
(Ecosphere, 2011-06-23)Urban habitat heterogeneity can modify interactions across species and lead to spatially fine grained differences in b-diversity patterns and their associated ecosystem services. Here, we study the impacts of landscape ... -
Cutaneous Leishmaniasis and sand fly fluctuations are associated with El Niño in Panamá
(PLOS ONE, 2014-10)Cutaneous Leishmaniasis (CL) is a neglected tropical vector-borne disease. Sand fly vectors (SF) and Leishmania spp parasites are sensitive to changes in weather conditions, rendering disease transmission susceptible to ... -
Demographic and pathogens of domestic, free-roaming pets and the implications for wild carnivores and human health in the San Luis Region of Costa Rica
(MDPI AG, 2021-04-20)Habitat loss and degradation, restricted ranges, prey exploitation, and poaching are important factors for the decline of several wild carnivore populations and additional stress from infectious agents is an increasing ... -
Detection of Rickettsia monacensis and Rickettsia amblyommatis in ticks collected from dogs in Costa Rica and Nicaragua
(Elsevier B.V, 2018-08-04)The neotropical climate of Central America provides ideal conditions for ticks, which may transmit several human pathogens, including spotted-fever group Rickettsia. Dogs may act as sentinels or reservoirs for human tick-borne ... -
Distribution of Culicoides sonorensis (Diptera: Ceratopogonidae) in Nebraska, South Dakota, and North Dakota: Clarifying the Epidemiology of Bluetongue Disease in the Northern Great Plains Region of the United States
(Entomological Society of America, 2011)The presence or absence of the biting midge Culicoides sonorensis Wirth & Jones (Diptera: Ceratopogonidae), a primary vector of bluetongue viruses (genus Orbivirus, family Reo viridae, BTV) in North America, was assessed ... -
Epidemiological, social, and control determinants of Chagas disease in Central America and Mexico - Group discussion
(Memórias do Instituto Oswaldo Cruz, 2007)The existence of Chagas disease in Central America was reported for the first time in El Salvador in 1913, four years after its discovery in Brazil. At that time only Triatoma dimidiata was known as a vector, but two ... -
Fine-scale variation in vector host use and force of infection drive localized patterns of West Nile virus transmission
(PLOS ONE, 2011-08-19)The influence of host diversity on multi-host pathogen transmission and persistence can be confounded by the large number of species and biological interactions that can characterize many transmission systems. For ... -
Flebótomos de Costa Rica (Diptera Psychodidae)
(Museo Nacional de Costa Rica, 1985-03)Esta monografía pretende dar a conocer y ampliar los conocimientos existentes sobre los flebótomos de Costa Rica, desde el punto de vista de su taxonomía, su distribución en el territorio nacional, y de algunos aspectos ... -
Genetic variability among populations of the sand fly Lutzomyia (Lutzomyia) Longipalpis (Diptera: psychodidae) from Central America
(Entomological Society of America., 1998-03)Eleven Central American populations of Lutzomyia longipalpis (Lutz & Neiva) were analyzed for genetic variation at 16 enzyme loci. The aim was to study the genetic structure among populations within this region and to ... -
Globally invasive, withdrawing at home: Aedes albopictus and Aedes japonicus facing the rise of Aedes flavopictus
(Springer, 2016)It has been suggested that climate change may have facilitated the global expansion of invasive disease vectors, since several species have expanded their range as tempera tures have warmed. Here, we present results from ... -
Increased adult Aedes aegypti and Culex quinquefasciatus (Diptera: Culicidae) abundance in a dengue transmission hotspot, compared to a coldspot, within Kaohsiung City, Taiwan
(MDPI, 2018-08-13)The assumption that vector abundance differences might drive spatial and temporal heterogeneities in vector-borne disease transmission is common, though data supporting it is scarce. Here, we present data from two common ... -
Leishmaniasis sand fly vector density reduction is less marked in destitute housing after insecticide thermal fogging
(BioMed Central, 2013)Background: Insecticide thermal fogging (ITF) is a tool to control vector borne diseases. Insecticide application success for vector control has been associated with housing materials and architecture. Vector abundance ... -
Macroecological patterns of American Cutaneous Leishmaniasis transmission across the health areas of Panamá (1980–2012)
(Elsevier B.V, 2016-03-18)American Cutaneous Leishmaniasis (ACL) is a neglected vector-borne zoonosis that persists despite increasing socio-economic development and urbanization in Panamá. Here, we investigate the association between environmental ... -
Modeling the association between Aedes aegypti ovitrap egg counts, multi-scale remotely sensed environmental data and arboviral cases at Puntarenas, Costa Rica (2017–2018)
(Elsevier, 2021-02)Problems with vector surveillance are a major barrier for the effective control of vector-borne disease transmission through Latin America. Here, we present results from a 80-week longitudinal study where Aedes aegypti (L.) ... -
Molecular characterization of Trypanosoma cruzi and infection rate of the vector Triatoma dimidiate in Costa Rica
(Universidad Nacional, Costa Rica, 2012-06-30)According to the genetic characterization by the analysis of the miniexon gene, strains of Trypanosoma cruzi can be classified into six discrete typing units (DTUs), and the DTU 1 into four distinct genotypes associated ... -
Mosquito species (Diptera: Culicidae) diversity from ovitraps in a Mesoamerican Tropical Rainforest
(Oxford University Press on behalf of Entomological Society of America, 2018-01-30)Mosquito sampling using efficient traps that can assess species diversity and/or presence of dominant vectors is important for understanding the entomological risk of mosquito-borne disease transmission.
