Spatial distribution and esterase activity in populations of Aedes (Stegomyia) aegypti (Linnaeus) (Diptera: Culicidae) resistant to temephos

Abstract: Introduction:The need for studies that describe the resistance patterns in populations of Aedes aegypti (Linnaeus) in function of their region of origin justified this research, which aimed to characterize the resistance to temephos and to obtain information on esterase activity in populations of Aedes aegypti collected in municipalities of the State of Paraíba. Methods: Resistance to temephos was evaluated and characterized from the diagnostic dose of 0.352mg i.a./L and multiple concentrations that caused mor… Show more

“…The scarcity of studies on Culicidae in Paraíba is one of the factors contributing to the lack of records of its species in the state. Many studies in the state are concentrated in the Aedes aegypti (Linnaeus, 1762) and Aedes albopictus (Skuse, 1894) species, dealing mainly with biological and bio-ecological studies on insecticide resistance [42][43][44][45], population [46] and competition genetics [47,48]. These both species were not founded during the catchings.…”

“…The intense and long-term use of chemical insecticides for vector control has selected for populations of resistant mosquitoes and reduced both the presence of susceptible individuals and the variability of field populations 1 . Chemical insecticides are still widely used in vector control programs, despite selection for resistant populations of Aedes aegypti and Aedes albopictus, which threatens the effectiveness of control programs 2 .…”

“…Temephos-containing larvicides in emulsifiable concentrate preparations, diluted solutions, granules, and slow release formulations 19 are commercially available, and can be applied in different ways depending on the place and rate of a required application 1 . Temephos-based larvicides have many advantages over other classes of insecticides, such as a low odor, low cost, and low toxicity 15 , and because they can be safely used in drinking water when the dosage do not exceed 56-112g/ha (5.6-11.2mg/m 2 ) or 1mg/l 20 .…”

“…Ciudades fronterizas de esta región, tales como Foz de Iguazú (Brasil) y Puerto Iguazú (Argentina) han reportado estudios de evaluación de resistencia de Ae. aegypti en los cuales hacen referencia a modificaciones en la susceptibilidad de las poblaciones naturales, identificando niveles bajos de resistencia a Temefos (12,20). Así, la aplicación de estos compuestos constituye una poderosa fuerza evolutiva, al permitir la sobrevivencia de aquellos individuos que poseen características fenotípicas de resistencia y éstos heredan esa capacidad a sus descendientes.…”
