Resistance of Aedes aegypti to temephos and adaptive disadvantages
OBJECTIVE To evaluate the resistance of Aedes aegypti to temephos Fersol 1G (temephos 1% w/w) associated with the adaptive disadvantage of insect populations in the absence of selection pressure. METHODS A diagnostic dose of 0.28 mg a.i./L and doses between 0.28 mg a.i./L and 1.40 mg a.i./L were used. Vector populations collected between 2007 and 2008 in the city of Campina Grande, state of P...
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 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 کاملTemephos resistance in two forms of Aedes aegypti and its significance for the resistance mechanism.
Aedes aegypti, at the larval stage, has been subjected to the temephos selection in laboratory. The level of temephos resistance was detected in a microplate by biochemical assay using WHO bioassay technique. The major enzyme-based resistance mechanisms involved in temephos resistance include elevated nonspecific esterase, oxidase and insensitive acetylcholinesterase. After 19 generations of te...
متن کاملResistance Status to the Insecticides Temephos, Deltamethrin, and Diflubenzuron in Brazilian Aedes aegypti Populations
Insecticides are still largely applied in public health to control disease vectors. In Brazil, organophosphates (OP) and pyrethroids (PY) are used against Aedes aegypti for years. Since 2009 Insect Growth Regulators (IGR) are also employed in the control of larvae. We quantified resistance to temephos (OP), deltamethrin (PY), and diflubenzuron (IGR) of A. aegypti samples from 12 municipalities ...
