TLDR
Although this pyrethroid was recently started to be used in the country to control the dengue vector, a decrease in susceptibility was noted between both periods analyzed, particularly in the city of Rio de Janeiro, indicating that resistance is due at least in part to a target site alteration.Abstract:
Resistance to cypermethrin of different Aedes aegypti Brazilian populations, collected at two successive periods (2001 and 2002/2003), was monitored using the insecticide-coated bottles bioassay. Slight modifications were included in the method to discriminate between mortality and the knock down effect. Although this pyrethroid was recently started to be used in the country to control the dengue vector, a decrease in susceptibility was noted between both periods analyzed, particularly in the city of Rio de Janeiro. The results indicate that resistance is due at least in part to a target site alteration.read more

TL;DR: The insecticide Chlorpirifos is a good candidate to be used with cipermetrina, ciflutrina, s cifLutrina to delay the development of resistance to pyrethroids in Ae.

TL;DR: The results showed that the resistance of synthetic pyrethroid has not been found, and following research should be attempt with another proven primers that would able to detect the insecticide resistance, or the following sophisticated research that could detect a new point of mutation.

TL;DR: There is a general trend of loss of susceptibility to products used for the control of Aedes aegypti, indicating that resistance management must be adopted when insect populations are in the “reduced susceptibility” status.

Ion Channels as Targets for Insecticides
TL;DR: At field-use rates, a neurotoxic effect of the ecdysteroid agonist RH-5849 is observed that involves blockage of both muscle and neuronal potassium channels, and the future use of ion channels as targets for chemical and genetically engineered insecticides is discussed.

Ion channels as targets for insecticides
TL;DR: The method with which the percentage of sodium channel population that needs to be modified to cause repetitive after-discharges can be measured accurately is developed and is applicable to other neuroactive drugs that act through the threshold phenomenon.

TL;DR: Exposure of larvae to the diagnostic dose of temephos revealed resistance in all localities examined, with mortality levels ranging from 4% (Pilares district, Rio de Janeiro, RJ) to 61.9% (Campos dos Goytacazes, RJ).
