La fauna flebotomica (Diptera: Psychodedae) de tres províncias de la region nor oriental del Marañon, Peru

Abstract

Two thousand seven hundred and seventy four sand flies were captured since 1987 to 1992 in endemic areas of human bartonellosis and Peruvian Verruga (district of San José de Lourdes, province of San Ignacio - 05 degrees 03' LS, and district of Lonya Grande, province of Utcubamba - 06 degrees 05'30" LS) belonging to the Northeast region of Marañon, Peru. Thirteen species were identified, 11 belonging to the genus Lutzomyia, 1 to Brumptomyia and the other to Warileya. Lutzomyia sp, close to L. serrana and L. maranonensis n. sp., Galatti, Cáceres & Le Pont are more prevalent (89.74% of the individuals captured). Suggests working of the kind. Lutzomyia verrucarum (Townsend, 1913) is reported in Utcubamba province for the first time.

Epidemiology of Andean Cutaneous Leishmaniasis: Incrimination of Lutzomyia Ayacuchensis (Diptera: Psychodidae) as a Vector of Leishmania in Geographically Isolated, Upland Valleys of Peru

“…ayacuchensis is that this species was found in two different areas of Peru separated by a considerable distance. One area was in the extreme northern part of Peru (inter-Andean valleys of Huancabamba, Huancabamba BGU, 9,20 inter-Andean valleys of Chinchipe 19 and Llaucano 20 ) and the other was in Ayacucho. These two areas are 1,200 km apart, without any reported Lu.…”

“…5,12 However, Lu. ayacuchensis was subsequently found in northern areas: 1) the North of Peruvian Andes (Piura in Huancabamba Province), 9 2) the neotropical rainforest (Cajamarca in San Ignacio Province), a Peruvian region located near the boarder with Ecuador, 19 3) areas endemic for Andean CL in the Llaucano Valley (Cajamarca in Chota Province), 20 and 4) the Andean valleys of Azuay and Chimborazo (Ecuador). 21,22 Despite extensive entomologic surveys, no specimens of Lu.…”

Estudio clínico epidemiológico de bartonelosis humana en el valle del Monzón, Huamalíes, Huánuco

“…Hasta hace algunos años, la mayor parte de las áreas endémicas se localizaba en los valles occidentales e interandinos, caracterizados por ser estrechos y profundos, de clima cálido que favorece la existencia de los vectores ( 13,15,16 ). Sin embargo, en los últimos años se ha notificado la existencia de nuevas áreas endémicas de bartonelosis y nuevos vectores de esta enfermedad, en zonas con ecología de selva alta, como en algunas provincias de la Región Nororiental del Marañón y en el Cuzco ( 17,18 ). Esto nos estaría indicando un cambio en la epidemiología de la enfermedad, asociado al contacto del hombre con nuevas fuentes de infección y vectores en las regiones selváticas, así como las migraciones humanas.…”

Taxonomy and Distribution of the Series <I>pia</I> of the <I>Lutzomyia verrucarum</I> Group (Diptera: Psychodidae), with a Description of <I>Lutzomyia emberai</I> n. sp.

“…This author also suggested that some Lutzomyia species could have crossed the Andes via the River Marañ on Valley in southern Ecuador and northern Peru during interglacial periods, when primary forests occupied the now dry valleys (Young 1979). Some evidence for this last route comes from the Þnding of pia series females in the Marañ on region of Peru (Cáceres et al 1995).…”
