The aim of the present work was to study the deltamethrin susceptibility of eggs from populations of Triatoma infestans and contribution of pyrethroid esterases to its degradation. Insects were from sylvatic areas Veinte ...

The cattle tick Boophilus microplus causes great damage in livestock and is considered one of the most important tropical ectoparasites. The traditional method of control is based on the intensive use of pesticides, however ...

Recently, high resistance to pyrethroid insecticides has been associated with ineffective field treatments against Triatoma infestans (Klug) in northern Argentina. Samples were collected from two areas in Argentina (Salta ...

Chagas disease is a zoonosis transmitted to man by blood-sucking triatomine bugs found in the Americas. Triatoma infestans (Klug, 1834) is the main vector of Chagas' disease in Argentina. The control of this illness relies ...

Objective: The ecotoxic effects of pesticide used for mosquito’s control TRISADA ® (TRI) [deltamethrin (D) 1%+tetramethrin (T) 0.33%, and piperonyl butoxide (PB) 0.29%] on amphibian larvae were investigated. Methods: In ...

The use of chemical insecticides is the main control method for Blattella germanica worldwide. The prolonged and frequent use of insecticides produced the selection of insecticide-resistant individuals. The German cockroach ...

Esterases are a group of enzymes that are reportedly associated with acaricide resistance in Riphicephallus (Boophilus) microplus. A comparative analysis was made of the esterase patterns in malathion and deltamethrin-sensitive, ...
