Monitoring of resistance to the pyrethroid cypermethrin in Brazilian Aedes aegypti (Diptera: Culicidae) populations collected between 2001 and 2003

Abstract

Resistance to cypermethrin of different Aedes aegypti Brazilian populations, collected at two successive periods (2001 and 2002/2003)

Variation in Aedes aegypti(Diptera: Culicidae) container productivity in a slum and a suburban district of Rio de Janeiro during dry and wet seasons

“…In Rio de Janeiro, mosquito control activity faces several drawback to be surpassed, such as (a) differences in the urbanization degree and socio-economic status of adjacent neighborhoods turn Rio de Janeiro into a mosaic, where vector control in each area require specific approaches (Luz et al 2003); (b) the high refusal of inhabitants to allow the entrance of control teams because they are afraid of urban violence; (c) the insecticide resistance of Ae. aegypti populations (Braga et al 2005, Da-Cunha et al 2005; and (d) the high genetic differentiation between Ae. aegypti populations within Rio de Janeiro city, what could lead to differences in mosquito ecology, behavior, and vectorial competence (Luz et al 2003, CostaRibeiro et al 2006.…”

Phenotypic and genotypic profile of pyrethroid resistance in populations of the mosquito Aedes aegypti from Goiânia, Central West Brazil

“…Worldwide, pyrethroids (PYs) are the most common class of insecticides used to control adult insects (2) . However, prolonged use of these insecticides has resulted in the evolution of PY-resistant mosquito populations in many countries, including Brazil (3) (4) .…”

Temporal variation of wing geometry in Aedes albopictus

“…For instance, the evolutionary changes within a species may produce populations that are resistant to insecticides (Braga et al 2004, da-Cunha et al 2005, Gómez et al 2011, Fontoura et al 2012 or may alter their vectorial capacity (Almeida et al 2005, Freitas 2010). Although microevolution has been investigated in the congeneric dengue vector Aedes aegypti (Lourenço-de-Oliveira et al 2004, Costa-Ribeiro et al 2007, Vidal & Suesdek 2012, the knowledge of microevolution in Ae.…”
