Publicación Acceso abierto Confirmación de la presencia de Lutzomyia Lutziana (Diptera: Psychodidae) en Colombia.(Bogotá, Colombia: Revista Caldasia, 2007., 2019-10-23) Bejarano, Eduar Elías; Duque, Patricia; Vélez, Iván DaríoThe presence of the sand fly Lutzomyia lutziana in Colombia is confirmed by one male specimen collected in the Serranía de La Macarena National Natural Park. This male was collected with a mouth aspirator, while resting in an armadillo nest. Lutzomyia lutziana resembles L. campograndensis, the former differing essentially by the slender tip of the genital filaments and the proportion of the length of the genital filaments and genital pump greater than 2,1.Publicación Acceso abierto Descripción del ARN de transferencia mitocondrial para Serina (UCN) de Lutzomyia columbiana (Diptera, Psychodidae).(Curitiba , Brasil: Revista Brasileira de Entomología, 2008., 2019-10-16) Pérez Doria, Alveiro; Bejarano, Eduar Elías; Vélez, Iván Darío; Sociedade Brasileira de Entomología.Description of the mitochondrial serine transfer RNA (UCN) of Lutzomyia columbiana (Diptera, Psychodidae). The sand fly Lutzomyia columbiana is considered a suspected vector of Leishmania mexicana and Leishmania braziliensis in Colombia. Lu. columbiana belongs to the Lutzomyia verrucarum species group, which included some sibling species. This has motivated the search for molecular markers to distinguish these taxa. In this paper, we described for the first time the putative secondary structure of the mitochondrial serine transfer RNA that recognizes the codon UCN of Lu. columbiana (tRNASer). DNA was extracted, amplified and sequenced from six individuals collected in human biting activity. The secondary structure of the tRNASer was inferred using the program tRNAscan-SE 1.21. The tRNASer gene length was 67 pair of bases (pb), and a single haplotype was detected among the six specimens sequenced. In the inferred secondary structure of the tRNASer of Lu. columbiana, the acceptor arm consisted of 7 bp, the dihydrouridine (DHU) arm of 3 pb, the anticodon arm of 5 pb, and the ribothymidine-pseudouridine-cytosine (TøC) arm of 5 pb. Similarity, the estimated size of the loops was 5 nucleotides in the DHU, 7 in the anticodon, 4 in the variable, and 7 in the TøC. Lu. columbiana differs from other Lutzomyia and Phlebotomus species sequenced to date by the presence of guanine in the nucleotide position 64, which induce a non-canonical base pair conformation type uracil-guanine in the acceptor arm. More studies are necessary to confirm the usefulness of the tRNASer as a suitable molecular tool for sand fly species identification.Publicación Acceso abierto Estimación del tiempo de desarrollo de Lutzomyia evansi bajo condiciones experimentales.(Barranquilla, Colombia: Salud Uninorte, 2012., 2019-10-08) Martínez Suárez, Claudia; Almanza Rodríguez, Carlos; Bejarano Martínez, Eduar ElíasThe objective of this research was to estimate the average development time of Lu. evansi, based on a laboratory colony composed of phlebotomineans from an urban area.Publicación Acceso abierto Primer Informe de Lutzomyia França en el Departamento de Guainía, Amazonia Colombiana, y de Brumptomyia mesai Sherlock (Diptera: Psychodidae) en el Litoral Caribe Colombiano.(Santo Antônio de Goiás ,Brasil: Neotropical Entomology , 2007., 2019-10-21) Bejarano, Eduar E; Castro, Mirley; Pérez Doria, Alveiro; Hernández Oviedo, Ela; Vélez, Andrés; Vélez, Iván D.; Sociedad Entomológica de Brasil.This is the first record of the presence of the medically important genus Lutzomyia França in the Department of Guainía, Colombia. Sand flies were collected biting humans in the surroundings of the urban area of the Municipality of Inírida. Three Lutzomyia species were taxonomically identifi ed as L. davisi (Root), L. olmeca bicolor Fairchild & Theodor, and L. antunesi (Coutinho). Additionally, Brumptomyia mesai Sherlock is cited for the first time in the Caribbean Coast of Colombia based on specimens collected with a modified CDC light trap in the Reserva Forestal Protectora Serranía de Coraza y Montes de María, Department of Sucre.Publicación Acceso abierto Primer registro de Lutzomyia scorzai y Lutzomyia reburra (Diptera: Psychodidae) en Antioquia, Colombia.(Bogotá, Colombia: Revista Colombiana de Entomologia, 2008., 2019-10-07) Vergara, Daniela; Bejarano, Eduar Elías; Carrillo, Lina María; Sierra, Diana; Vélez, Iván Darío; Sociedad Colombiana de Entomología.Seven species of Lutzomyia and one of Brumptomyia were collected while surveying two cutaneous leishmaniosis foci in the department Antioquia, Colombia, these are: Lutzomyia gomezi, Lu. scorzai, Lu. trapidoi, Lu. triramula, Lu. panamensis, Lu. aragaoi, Lu. reburra and Brumptomyia galindoi. Lu. scorzai (subgenus Helcocyrtomyia) and Lu. reburra (subgenus Trichophoromyia) are new records for the department. The specimens of Lu. scorzai were captured using a Shannon light trap in the municipality of Tarazá, while those of Lu. reburra were collected using CDC-like light traps near a nest of armadillo in the municipality of Urrao. The biogeographic importance of these findings is discussed given the limited distribution of both species in Colombia.
