SALAZAR C, Neil et al. Comparación de dos métodos de colecta para Anophelinos (Cebo humano y trampa de luz CDC), durante la época seca y lluviosa, Yurimaguas, Perú 2005.. Rev. perú. med. exp. salud publica [online]. 2006, vol.23, n.2, pp.87-97. ISSN 1726-4634.

Objective: To assess the effectiveness of two collection methods for adult anopheline mosquitoes (human bait and light CDC traps) within households and in their surroundings during rainy and dry seasons between January and June 2005 in an endemic area for malaria in Yurimaguas District, Loreto Department, Peru. Material and methods: Adult mosquito collection using human bait and CDC light traps were performed in five locations: San Juan, Santa Rosa, Central, San Antonio, and Florida in Munichis Municipality in Yurimaguas. Nine households were selected for each collection method. Linear regression, quadratic and cubic equations were estimated for calculating the number of anopheline mosquitoes collected using human bait compared to data from capture using light traps. Results: 7790 anopheline mosquitoes were captured using human baits and 1252 using light traps. During the study nine Anopheles species were identified, and the four most frequently found were: Anopheles benarrochi Gabaldon, Cova & Lopez, 1941 (85,2%); Anopheles rangeli, Gabaldon, Cova & Lopez, 1940 (7,3%); Anopheles konderi, Galvao & Damasceno, 1942 (4,0%); and Anopheles triannulatus, Neiva & Pinto, 1922 (3,1%). CDC light traps captured 16,4%, 15,3%, and 17,1% of all anopheline mosquitoes, within the households and their surroundings, respectively, compared to those captured using human bait. There were no differences between dry and rainy seasons in any of assessed parameters. Conclusions: Three regression models are proposed for estimating the number of anopheline mosquitoes in human baits within the households and in their surroundings from the use of CDC light traps.
