    Were recorded for the first time Triatoma dispar species at an altitude of 1,200 masl in Milpe km 90, Canton San Miguel de los Bancos, Province of Pichincha and its geographical distribution is updated in Ecuador. Triatomines were collected during a sandflies study (Leishmania vectors) in peridomestic areas and forest remnants. Milpe km 90 did not present clinical evidence or transmission of the Chagas disease or enzootic circulation of Trypanosoma cruzi; however is in an area of high epidemiological risk. The present work contributes to the inventory of the Ecuador triatomine fauna and updating geographical distribution of T. dispar, a wild species with vectorial potential, which has already colonized domestic and peridomestic environments in Esmeraldas and Loja.

    Population variation of Rhodnius prolixus (Reduviidae: Triatominae) in Attalea butyracea (Arecaceae) in the Colombian Orinoquia región.
    (Universidad del Valle, 2018-12-31) Urbano, Plutarco; Hincapié, Eduwin; Angulo, Víctor Manuel; Esteban, Lyda; Núñez Avellaneda, Luís Alberto; Sociedad Colombiana de Entomología - Socolen; Universidad del Valle; Montoya Lerma, James
    The objective of this study was to determine the population density of Rhodnius prolixus and its developmental stages in natural forests of Attalea butyracea during a hydrological period in flooded savanna ecosystems of the Colombian Orinoquia region. One hundred twenty (120) palms were sampled over a period of one year using live bait traps for Triatomine bugs. Sampling showed that R. prolixus presents a high population density throughout the year, which increases during periods of low rainfall and decreases during the months of greatest precipitation. It was also found that all developmental stages of R. prolixus are presented throughout the year, although there are differences in their representation; showing decreases in density as developmental stages advance. Additionally, infestation, colonization and clustering were observed. The above suggests that the species presents population stability in A. butyracea forests without regard to climatic period, as well as reproductive success; thus individuals have the capacity to disperse and colonize other microhabitats at any time, regardless of climatic condition

    Primer registro del género Systelloderes (Hemiptera: Heteroptera: Enicocephalidae) en Guzmania multiflora (Bromeliaceae) en Colombia.
    (Universidad del Valle, 2018-07-08) Ospina Bautista, Fabiola; Llano, Camilo; Realpe, Emilio; Sociedad Colombiana de Entomología - Socolen; Universidad del Valle; Montoya Lerma, James
    Se conoce poco sobre la relación entre depredadores de la familia Enicocephalidae y plantas. Se reporta la presencia de dos especies de Systelloderes habitando en plantas de Guzmania multiflora (Bromeliaceae) en un bosque de montaña de Colombia. Este estudio se llevó a cabo en la Reserva Forestal Protectora de las Cuencas Hidrográficas de Rio Blanco y Quebrada Olivares Manizales, Caldas, Colombia, donde se recolectaron bromelias entre cero y tres metros de altura. Aunque especies de Systelloderes habían sido reportadas con anterioridad en Colombia, este género no había sido encontrado dentro de bromelias.
