“…In addition, these two species showed a high preference to bite humans in most of the sampled locations, with very few specimens collected in livestock corrals (figure 2). Besides, the natural infection of A. nuneztovari and A. darlingi with the Plasmodium parasite, together with the data showing that both species presented the highest mean mosquito densities (up to 14.2 mosquitoes/person/night and 6.9 mosquitoes/person/night, respectively), are two important results that reinforce reports on their highly anthropophilic feeding habits and their role as primary malaria vectors (5)(6)(7)16).…”

“…In seven of the nine locations sampled during March and May, 2015, A. nuneztovari mosquitoes were present except in El Rayo-TAZ (Antioquia) and San Francisco de Tauchigadó-MAT (Chocó). Similarly, other studies have found A. nuneztovari in some locations of Antioquia and Chocó (6,7,11,16,26). Interestingly, the last report of A. nuneztovari in Chocó dates from 2004 (26), which evidences the importance of continuously listing malaria vectors present in the different regions of Colombia and keeping updated information for vector control strategies.…”

“…In this study we analyzed species abundance and composition, biting preferences and natural infection with Plasmodium of Anopheles mosquitoes from nine locations of two malaria-endemic regions of Colombia. Results showed a predominance of A. nuneztovari mosquitoes (53.5%), followed by A. darlingi (34.5%), known as the main malaria vectors in the country (5)(6)(7)16). In seven of the nine locations sampled during March and May, 2015, A. nuneztovari mosquitoes were present except in El Rayo-TAZ (Antioquia) and San Francisco de Tauchigadó-MAT (Chocó).…”

“…However, species composition and frequencies vary among sampling sites and seasons, rendering constant monitoring of these parameters essential (7,12).

“…Anopheles species reported until now (3,4); based on entomological and epidemiological data, three of them have been recognized as primary malaria vectors: Anopheles albimanus, A. darlingi and A. nuneztovari (3,(5)(6)(7). Other species have been incriminated as secondary or local vectors, among them, A. pseudopunctipennis, A. punctimacula, A. neivai, A. rangeli, A. oswaldoi (8,9).…”

Introduction:In Colombia there are three Anopheles species implicated in malaria transmission as primary vectors; however, the local role of some Anopheles species must still be defined. Objective: To determine the abundance, composition and natural infection rates for Anopheles mosquitoes with Plasmodium spp. in two malaria-endemic regions of Colombia. Materials and methods: Anopheles mosquitoes were collected using the human-landing catches and while resting in livestock corrals in nine localities of two malaria-endemic regions of Colombia. Mosquitoes were morphologically identified and confirmed by PCR-RFLP-ITS2. Identified mosquitoes were processed and tested for Plasmodium parasite infection by ELISA and ssrRNA-based nested PCR. Results: We collected 1,963 Anopheles mosquitoes corresponding to nine species. The most abundant species were Anopheles nuneztovari (53.5%) and A. darlingi (34.5%), followed by A. triannulatus s.l. (6%), and other species (≈5.9%). Three species were naturally infected with Plasmodium spp.: A. darlingi, A. nuneztovari and A. triannulatus s.l. Conclusions: Natural infection of A. darlingi and A. nuneztovari indicate that these malaria vectors continue to be effective carriers of Plasmodium in the localities under study in Valle del Cauca and Chocó. Additionally, the infected A. triannulatus s.l. collected in livestock corrals in the locality of the department of Córdoba suggests the need for further studies to define the epidemiological importance of this species given its abundance and opportunistic anthropophilic behavior.

Blood feeding habits of mosquitoes: hardly a bite in South America

2022

Mosquito blood feeding plays a key role in epidemiology. Despite its importance and large number of studies worldwide, less attention has been paid in South America. We summarized some general concepts and methodological issues related to the study of mosquito blood feeding habits, and compiled and analyzed all published information regarding the subject in the continent until 2020. Available literature comprised 152 scientific studies, that pursued different approaches: human landing catches (102 studies), baited trap (19), and blood meal analyses of collected specimens (38). Among the latter, 23 used serological and 15 molecular techniques. Species most frequently studied were those incriminated in malaria transmission, whereas relevant vectors such as Aedes aegypti , Ae. albopictus , and Haemagogus janthinomys were surprisingly neglected. Brazil was the leading country both in number of works and species studied. For over 70% of the species and three out of 13 South American countries there is no single information on mosquito blood feeding habits. Data from baited traps included 143 mosquito species, 83.9% of which were attracted to humans, either exclusively (10.5%) or in combination with other vertebrates (73.4%). Host blood identification of field collected specimens provided data on 102 mosquito species, and 60.8% of these fed on humans (55.9% combined with other vertebrates). Only 17 of the 73 species assessed by both methods yielded similar feeding patterns. Finally, supplementary tables are provided in a comprehensive summary of all information available and information gaps are highlighted for future research in the continent. Supplementary Information The online version contains supplementary material available at 10.1007/s00436-022-07537-0.
