Development of permethrin resistance in Culex quinquefasciatus Say in Kuala Lumpur, Malaysia.
The resistance status towards permethrin among the laboratory strain, the permethrin-selected strain and four field strains of Culex quinquefasciatus collected in Kuala Lumpur, Malaysia was determined using three standard laboratory methods: WHO larval bioassay, WHO adult bioassay and biochemical microplate assay. Cx. quinquefasciatus permethrin-selected strain larvae were the least susceptible...
متن کاملUse of isogenic strains indicates CYP9M10 is linked to permethrin resistance in Culex pipiens quinquefasciatus.
Previous studies on a strain of Culex pipiens quinquefasciatus from Saudi Arabia indicated permethrin resistance was a result of cytochrome P450 mediated detoxification and kdr. The P450 detoxification was found to be larval specific and associated with a fitness cost in certain environments. The P450 responsible for resistance (and the fitness cost) has not been identified, but recently two ca...
متن کاملRESPONSE OF Culex quinquefasciatus LARVAE TO THREE INSECTICIDES
The adult females of Culex quinquefasciatus are vectors responsible for transmission of different arboviruses and lymphatic filariasis. The mosquito has anthropophilic and endophilics habits, their larvae develop in almost all habitats modified by humans. Different insecticides groups such as organophosphates, carbamates, and pyrethroids have been widely used in mosquito control, but in some pl...
متن کامل[Susceptibility of Culex quinquefasciatus larvae to different insecticides].
INTRODUCTION This study aimed to assess the susceptibility of Culex quinquefasciatus larvae to two pyrethroids (Cypermethrin and Deltamethrin), two derivatives of Avermectin (Ivermectin and Abamectin) and an organophosphate (Temephos). METHODS Third- and fourth-instar larvae of C. quinquefasciatus were exposed to different concentrations of insecticides (eleven repetitions) according to the W...
متن کاملInterspecies predation between Anopheles gambiae s.s. and Culex quinquefasciatus larvae.
Interaction of aquatic stages of coexisting mosquito species may have significant influence on resulting adult mosquito populations. We used two coexisting species, Anopheles gambiae s.s. and Culex quinquefasciatus to investigate whether third instars of one species consumed first instars of the other. First instars of one species were readily consumed by a third instar of the other species irr...
