 en Anthropophilic Anopheles check for this species in other resources species composition and malaria in Tierradentro, Córdoba, Colombia
Schiemann, David Joachim; Pinzón, Martha Lucía Quiñones & Hankeln, Thomas

Abstract

Malaria is still a primary health problem in Colombia. The locality of Tierradentro is situated in the municipality of Montelíbano, Córdoba, in the northwest of Colombia, and has one of the highest annual parasite index of malaria nationwide. However, the vectors involved in malaria transmission in this locality have not yet been identified. In this study, the local anthropophilic Anopheles check for this species in other resources composition and natural infectivity with Plasmodium check for this species in other resources were investigated. In August 2009, 927 female Anopheles mosquitoes were collected in eight localities using the human landing catch method and identified based on their morphology. Cryptic species were determined by restriction fragment length polymorphism-internal transcribed spacer (ITS)2 molecular analysis. Eight species [ Anopheles nuneztovari s.l. check for this species in other resources (92.8%), Anopheles darlingi check for this species in other resources (5.1%), Anopheles triannulatus s.l. check for this species in other resources (1.8%), Anopheles pseudopunctipennis s.l. check for this species in other resources (0.2%), Anopheles punctimacula s.l. check for this species in other resources (0.2%), Anopheles apicimacula check for this species in other resources (0.1%), Anopheles albimanus check for this species in other resources (0.1%) and Anopheles rangeli check for this species in other resources (0.1%)] were identified and species identity was confirmed by ITS2 sequencing. This is the first report of An. albimanus, An. rangeli and An. apicimacula in Tierradentro. Natural infectivity with Plasmodium was determined by ELISA. None of the mosquitoes was infectious for Plasmodium. An. nuneztovari s.l. was the predominant species and is considered the primary malaria vector; An. darlingi and An. triannulatus s.l. could serve as secondary vectors.
