Se llevó a cabo un estudio faunístico en el estado de Quintana Roo para conocer la distribución, riqueza y abundancia de los flebotominos. Se observó una gran variabilidad del promedio de especies y abundancia dentro y entre tres diferentes zonas (sur, centro y norte) en el estado. La mayor abundancia y riqueza se registró en la zona norte, en la zona centro y sur se capturaron igual número de especies, y la zona centro tuvo la menor abundancia. En cada zona fueron diferentes las especies dominantes, aunque, Lutzomyia shannoni y Lutzomyia cruciata se registraron dentro de las más dominantes distribuidas en las tres zonas. Entre las especies dominantes que se presentan en el estado se encuentran aquellas que son incriminadas como vectores de leishmaniasis en la Península de Yucatán. Los factores ambientales que se presentan en el estado son reflejados en las abundancias encontradas en las diferentes zonas de Quintana Roo.

A faunistic study was carried out to gain insight into the distribution, species richness and abundance of sandflies in Quintana Roo, Mexico. There was a great intra-and interregional variability in mean species richness and abundance in Quintana Roo. The northern region appeared to have the highest species richness and abundance, followed by the central and southern regions, which exhibited an equal richness between them. Also, the central region showed the lowest sandfly abundance. Each region showed a rather distinctive dominant species composition, although two species, Lutzomyia shannoni and Lutzomyia cruciata, were among the most abundant in all three regions. In fact, some of the most abundant speciesare suspected vectors of leishmaniasis at the Yucatan Peninsula.

Effect of trapping methods on the estimation of alpha diversity of a phlebotomine sandfly assemblage in southern Mexico

“…The dominance of these three species may be due to their marked anthropophilic behaviour as observed in several previous studies (e.g. Biagi et al ., ; Rebollar‐Téllez et al ., ; Pech‐May et al ., , ; Sánchez‐García et al ., ; May‐Uc et al ., ). Furthermore, these species, together with L. olmeca olmeca , have been incriminated as vectors of Leishmania mexicana (Biagi et al ., ; Rebollar‐Téllez et al ., , , ; Pech‐May et al ., , ; Sánchez‐García et al ., ).…”

“…The present study, assessing the phlebotomine sandfly assemblage using 12 different traps, provided a species richness of 13 phlebotomine sandfly species, representing 26% of all Phlebotominae species reported so far in Mexico (Vargas & Díaz‐Nájera, ; Ibáñez‐Bernal, , ; Ibáñez‐Bernal et al ., ; , , ; Godínez‐Álvarez & Ibáñez‐Bernal, ; Ibáñez‐Bernal et al ., ), 50% in Yucatan Peninsula (Rebollar‐Téllez et al ., , , ; Ibáñez‐Bernal et al ., ; May‐Uc et al ., ) and 54% of species of Quintana Roo (Ibáñez‐Bernal et al ., ; May‐Uc et al ., ). Although 12 of the species collected were previously known in Mexico, Lutzomyia manciola (2♀) represents a new record for the country but was described by Ibáñez‐Bernal () in Belize.…”

“…Shannon traps were by far the most efficient sampling method in this tropical forest. Similar results were obtained in several studies in the Mexican southeastern states of Campeche (Rebollar‐Téllez et al ., ; Pech‐May et al ., , ), Yucatan (Rebollar‐Téllez et al ., ), Quintana Roo (Cruz‐Ruiz et al ., ; Sánchez‐García et al ., ; May‐Uc et al ., ) and Chiapas (Pérez et al ., ). It is important to highlight that Shannon traps were primarily developed to collect sylvan mosquitoes using a horse as a bait during an epidemic of jungle yellow fever in Mato Grosso and Rio de Janeiro, Brazil (Shannon, ), and many years later, Pérez et al .…”

“…Even though the study of May‐Uc et al . () shed light on the diversity structure of sandflies in the state of Quintana Roo, other questions remained unanswered. For instance, the diversity structure over a longer period (for instance an annual cycle) has not been documented.…”

Comparative Field Evaluation of Different Traps for Collecting Adult Phlebotomine Sand Flies (Diptera: Psychodidae) in an Endemic Area of Cutaneous Leishmaniasis in Quintana Roo, Mexico

“…The Disney trap (Disney, 1966) is a rodentbaited trap, which has been used with rodents species as baits (Rebollar-Téllez et al 2005, Pech-May et al 2010, Sá nchez-García et al 2010, May-Uc et al 2011, Pérez et al 2014, as well as with different species of mammals serving as baits (Disney 1968, Thatcher 1968, Christensen and Herrer 1973, Rebollar-Téllez et al 2005. The sticky trap is a common method of capture by passive interception is and easy to install in any remote region (Alexander 2000).…”
