Toxicity of spinosad to temephos-resistant Aedes aegypti populations in Brazil
The mosquito Aedes aegypti is the primary vector of different arboviruses and represents a major public health problem. Several Brazilian populations of Ae. aegypti have developed resistance to temephos, the most used organophosphate larvicide. New tools which are less harmful to the environment and safer for humans are becoming increasingly important to control this insect vector. Spinosad, an...
متن کامل[Susceptibility of Aedes aegypti to temephos and cypermethrin insecticides, Brazil].
Bioassays were performed in order to detect the susceptibility of Aedes aegypti to the chemical insecticides temephos and cypermethrin. The results showed that this species is susceptible to temephos and presents resistance to cypermethrin.
متن کاملLarvicidal Efficacy of Temephos against Aedes Aegypti
Three new formulations of temephos (LAVIFOS SG 1%, MOSQ SG 1% and AZAI-SS ZG 1%) were evaluated for larvicidal efficacy against larvae of Aedes aegypti (L.) in waterstorage jars under field-simulated conditions. LAVIFOS SG 1% and MOSQ SG 1% are sand granule formulations, whereas AZAI-SS ZG 1% is zeolite granule formulation. Each formulation contained 1% temephos as an active ingredient. Each fo...
متن کاملSpatial distribution and esterase activity in populations of Aedes (Stegomyia) aegypti (Linnaeus) (Diptera: Culicidae) resistant to temephos.
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...
متن کامل[Susceptibility of Aedes aegypti larvae to the insecticide temephos in the Federal District, Brazil].
OBJECTIVE To study the susceptibility status of Aedes aegypti to the organophosphate insecticide temephos. METHODS Samples of Ae. aegypti larvae were obtained, using ovitraps, from eight cities of the Federal District, central Brazil, in 2000 and 2001. Larvae were submitted to the diagnostic dose of 0.012 mg/l temephos, as recommended by standard World Health Organization methodology. Field p...
