[Anopheles darlingi (Diptera: Culicidae) Rood 1926: Morphometric variations in wings and legs of populations from Colombia].

Introduction: Natural populations of Anopheles darlingi, the main malaria vector in Colombia, have shown phenotypic variations in some of their diagnostic characters.

Objective: To characterize morphometric variations in wing spot patterns and diagnostic characters of the hind leg of adult females of An. darlingi collected in areas where malaria is endemic.

Territorial analysis of Aedes aegypti distribution in two Colombian cities: a chorematic and ecosystem approach.

A territorial analysis of Aedes aegypti density was conducted in two Colombian cities using an ecosystem and chorematic approach. Entomological and behavioral data (by cluster) and information on the urban context were used to analyze the relationship between territorial structures and dynamics and vector density. The results were represented in graphic (chorematic) models.

First published record of urban malaria in Puerto Gaitán, Meta, Colombia.

Patterns of malaria cases were compared between the department of Meta and the municipality of Puerto Gaitán, Colombia, to examine temporal change in malaria from 2005-2010. During this time frame in Meta the mean ratio was 2.53; in contrast, in Puerto Gaitán it was 1.

[Susceptibility of natural populations of dengue vector to insecticides in Colombia].

Introduction: Physiological resistance of natural population of Aedes aegypti to insecticides contribute to the decreased efficacy of chemical control as a main control strategy during dengue outbreaks.

Objective: The susceptibility status of Ae. aegypti was assessed for the carbamate propoxur, the adulticide malathion and the larvicide temephos on 13 natural populations of Ae.

[Susceptibility of Aedes aegypti to DDT, deltamethrin, and lambda-cyhalothrin in Colombia].

Objectives: To assess the susceptibility status of 13 natural populations of Aedes aegypti (collected from sites in Colombia where dengue is a serious public health problem) to the pyrethroids, deltamethrin and lambda-cyhalothrin, and to the organochlorine, DDT, and to identify any biochemical mechanisms associated with resistance.

Methods: Immature forms of the vector were collected from natural breeding spots at each site and then raised under controlled conditions. Using the F2 generation, bioassays were performed using the World Health Organization's 1981 methodology (impregnated paper) and United States Centers for Disease Control and Prevention's 1998 methodology (impregnated bottles).
