“…The ND4 mitochondrial gene, which codifies the subunit 4 of the NADH dehydrogenase enzyme, is an effective tool to analyze genetic population structure and colonization events in A. aegypti. Such analyses were carried out in mosquito populations from Brazil (TWERDOCHLIB et al 2012), Bolivia (PAUPY et al 2012), Peru (YÁÑEZ et al 2013), Venezuela (URDANETA-MARQUEZ et al 2008) and Mexico (GORROCHOTEGUI-ESCALANTE et al 2002). So far, only RAPDs (Random Amplified Polymorphic DNA) (OCAMPO & WESSON 2004, MEJÍA et al 2011) and more recently the mtDNA (CALDERA et al 2013) have been used to analyze the genetic structure of A. aegypti populations in Colombia.…”

“…Low genetic diversity is most likely a result of a decline in population size caused by insecticide use, as it was observed in American A. aegypti populations [72][73][74] . However, some studies have revealed the presence of greater genetic diversity in areas that are frequently treated with insecticides, as shown in A. aegypti populations from French Polynesia and Brazil [75][76] .…”

Introduction: Aedes (Stegomyia) albopictus (Skuse, 1894) is a vector for dengue and chikungunya viruses in the field, along with around 24 additional arboviruses under laboratory conditions. Knowledge of the genetic diversity of insect vectors is critical for the effective control and elimination of vector-borne diseases. Objective: We determined the current scenario of the genetic diversity in natural populations of A. albopictus through a systematic review. Methodology: It was possible to establish the first reports and distribution of A. albopictus populations in the world, as well as its genetic diversity, population genetic structure and molecular markers used to determine its genetic diversity. Results: A. albopictus is distributed worldwide with genetically structured populations and low diversity; however, 89.5% of the genetic diversity known is based on the use of RFLP, allozymes, isozymes, and mtDNA molecular markers that exhibit significant problems according to the literature. After the results were obtained, a critical analysis was carried out and existing shortcomings were detected. Conclusion: The current knowledge of genetic diversity of A. albopictus is based on genetic markers that exhibit significant problems reported in the literature; therefore, vector control programs targeting A. albopictus populations, may be compromised.

“…En Lima se registró por primera vez en el año 2000 en cinco distritos (La Victoria, El Agustino, Rímac, San Juan de Lurigancho y Cercado de Lima), posteriormente se extendió a otros 26 distritos de Lima y 3 distritos del Callao (13) . Por otro lado, la identificación de cinco haplotipos de Aedes aegypti en nuestro país nos indica que esta variabilidad genética se debería tanto a la migración activa del vector como a la migración pasiva mediada por la actividad humana (14,15) .…”

Rev Peru Med Exp Salud Publica. 2015;32(1):146-56. RESUMENUn problema sanitario cada vez más frecuente y disperso en áreas tropicales y subtropicales del mundo, incluido el Perú donde ingresó en 1990, es el dengue. Es producido por el virus del dengue con cuatro serotipos y transmitido por el Aedes aegypti, vector que convive con los humanos y cuya presencia es favorecida por deficientes condiciones sanitarias, sociales y económicas. Manifestaciones de formas severas de la enfermedad como el choque y sangrado, están relacionadas con la frecuente cocirculación de los cuatro serotipos y la aparición de nuevos genotipos como el americano/asiático del serotipo 2. La nueva clasificación de la enfermedad por la OMS como dengue con o sin signos de alarma y dengue grave, está contribuyendo a un diagnóstico y tratamiento más oportunos, permitiendo reducir la letalidad. Debe destacarse la necesidad de la vigilancia del síndrome febril y los índices aédicos que contribuyan a un diagnóstico oportuno y orienten las medidas de control vectorial mediante educación sanitaria y manejo ambiental con participación comunitaria e intersectorial, de manera creativa según los nichos ecológicos. Una alternativa de prevención complementaria sería la vacunación utilizando vacunas tetravalentes cuya seguridad y eficacia deben estar garantizadas antes de su uso poblacional en el marco de estrategias integrales.

ABSTRACTA health problem each time more frequent and dispersed in tropical and subtropical areas of the world, including Peru where it entered in 1990, is dengue. It is produced by the dengue virus with four serotypes and transmitted by Aedes aegypti, a vector that coexists with humans and whose presence is favored by deficient sanitary, social and economic conditions. Manifestations of severe forms of the disease such as shock and bleeding, are related to the frequent co-circulation of the four serotypes and the emergence of new genotypes such as American / Asian serotype 2. The new classification of the disease by WHO as dengue with or without warning signs and severe dengue, is contributing to more timely diagnosis and treatment, enabling reductions in mortality. Of note is the need to highlight the surveillance of acute febrile illness and Aedes indices that contribute to a timely diagnosis and guide vector control measures through sanitary education and environmental management with community and intersectoral participation, in a creative manner according to ecological niches. An alternative for complementary prevention would be vaccination using tetravalent vaccines whose safety and efficacy must be guaranteed before its use in the population under the framework of comprehensive strategies.
