The latter is a new record for the country.

Los Calliphoridae se encuentran en una gran variedad de hábitats, mostrando preferencia por los ambientes humanos, fenómeno conocido como sinantropía. La importancia de estas moscas, a nivel ecológico, médico y sanitario, radica en que sus hábitos de alimentación y desarrollo tienen lugar en excretas, basuras, materia orgánica en descomposición y cadáveres de animales. Además, son vectores mecánicos de patógenos y causantes de miasis. El propósito de este estudio fue determinar el índice de sinantropía (SI) de adultos de Calliphoridae presentes en La Pintada-Antioquia, Colombia, mediante muestreos mensuales simultáneos en tres ambientes (urbano, rural y bosque), para lo cual se utilizaron trampas van Someren Rydon cebadas con excremento humano, vísceras de pollo, pescado y cebolla en descomposición. En cada zona se pusieron cuatro trampas (una por atrayente), durante 48 horas cada mes, realizando colectas cada 12 horas. Se colectaron 2406 individuos, pertenecientes a 10 especies. Chysomya megacephala (SI = + 96,47) mostró fuerte preferencia por asentamientos urbanos densos. Cochliomyia macellaria (SI = + 78,1), Lucilia eximia (SI = + 74,94) y Chysomya albiceps (SI = + 59,12) tuvieron preferencia por asentamientos humanos (eusinantrópicas). Hemilucilia semidiaphana (SI = -50) mostró rechazo por los asentamientos humanos (asinantrópica). Por su parte, Cochliomyia hominivorax, Chloroprocta idioidea, Lucilia cuprina, Hemilucilia segmentaria y Paralucilia pseudolyrcea fueron poco abundantes y no se determinó su SI. La abundancia mensual y la eficiencia en la atracción de cebos, se discutieron de acuerdo con su importancia médica y sanitaria. Se registra por primera vez Paralucilia pseudolyrcea en Colombia. Las especies sinantrópicas podrían estar involucradas en la transmisión de patógenos en esta localidad.

Calliphoridae are found in a variety of habitats, showing preference for human environments, a phenomenon known as synanthropy. The medical, ecological and sanitary importance of these flies resides in their feeding and development habits, which occur in excrement, garbage, decomposing organic matter and animal carcasses. In addition, they are mechanical vectors of pathogens and causal agents of myiasis. The objective of this study was to determine the synanthropic index (SI) of adult Calliphoridae in La Pintada-Antioquia, Colombia, through simultaneous monthly samplings in three environments (urban, rural, and forest) using van Someren Rydon traps baited with human excrement, decomposing chicken viscera, fish and onion. Four traps (one for each bait) were placed in each environment for 48 hours each month, making collections every 12 hours. A total of 2406 individuals was captured belonging to 10 species. Chysomya megacephala (SI = + 96.47) showed the strongest preference for dense human settlements. Cochliomyia macellaria (SI = + 78.1), Lucilia eximia (SI = + 74,94) and Chysomya albiceps (SI = + 59.12) had preferences for human settlements (eusynanthropic). Hemilucilia semidiaphana (SI = -50) showed a preference away from human settlements (asynanthropic). Cochliomyia hominivorax, Chloroprocta idioidea, Lucilia cuprina, Hemilucilia segmentaria and Paralucilia pseudolyrcea were collected in small numbers, and their SI could not be determined. The monthly abundance and the efficiency of the attractiveness to baits are discussed according to their medical and sanitary importance. Paralucilia pseudolyrcea is recorded for first time in Colombia. Synanthropic species could be involved in the transmission of pathogens in this locality.

The finding of Panstrongylus geniculatus nymphs inside a house in northeastern Antioquia, Colombia, and the reports related to their increasing presence in homes suggest the need for surveillance methods for monitoring the invasion processes. We analyzed the morphological differences between a wild population and its laboratory descendants, using the techniques of geometric morphometry, with the idea that such differences might parallel those between sylvatic and synanthropic populations. The analyses over five generations showed differences in size but not in shape. Head size and wing size were both reduced from sylvatic to laboratory populations, but the decrease in head size occurred only up to the second generation while the decrease in wing size proceeded up to the fifth generation. In contrast, although a decrease in sexual size dimorphism has been proposed as a marker of colonization in human dwellings, we did not detect any significant loss of dimorphism between sexes of P. geniculatus over the five generations studied. We conclude that size changes may have a physiological origin in response to a change of ecotopes, but more than five generations may be required for the expression of permanent morphological markers of human dwellings colonization.
