RESPONSE OF Culex quinquefasciatus LARVAE TO THREE INSECTICIDES
نویسندگان
چکیده
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 places, the temephos has shown ineffectiveness for effective control of C. quinquefasciatus as a result of resistance development. So, there is a need of monitoring the populations through periodic studies for the detection of susceptibility.

Larvicidal potential of Cyathea species against Culex quinquefasciatus
Resistance to insecticides has persuaded researchers to find new methods to control Culex quinquefasciatus proliferation. Plants may be a source of alternative agents for mosquito control due to ever-growing insecticide resistance in mosquito vectors and environmental imbalance caused by synthetic insecticides. The present study was intended to study the larvicidal activity of selected Cyathea ...

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 کاملRelative susceptibility of some common mosquito vector larvae to synthetic insecticidal compounds in north-western Rajasthan.
Relative susceptibility of three important mosquito vector larvae viz., Anopheles stephensi, Aedes aegypti and Culex quinquefasciatus, prevalent in the arid region was determined against four organophosphates (malathion, fenitrothion, fenthion, temephos) and three synthetic pyrethroid (alphamethrin, deltamethrin and fanvalerate) compounds. Studies were carried out on late 3rd or early 4th insta...

Background Culex quinquefasciatus (Diptera: Culicidae) is an important vector for many human diseases. The aim of this study was to evaluate the susceptibility level of larval and adult stages of Cu. quinquefasciatus to different groups of WHO recommended insecticides for vector control. Methods Larval stages of the Culex mosquitoes were collected from their natural habitats in Rafsanjan Coun...
متن کاملEfficacy of two organophosphorus insecticides, Reldan & Dursban against the larvae of Culex quinquefasciatus.
BACKGROUND & OBJECTIVES The resistance in vectors to conventional insecticides warrants development of newer insecticides for mosquito control besides use of other counter-measures. The present study was undertaken to test the efficacy of a new and toxicologically safe organophosphorus compound, Reldan (chlorpyrifos-methyl) and compare its efficacy with Dursban (chlorphyrifos-ethyl) against lar...
