Resistant status of complex species to different imagicides in Tehran, Iran.

Background & Objectives: Insecticides are the most important means of controlling pests in Iran especially for Culex pipiens complex species. The rational use of insecticides largely depends on understanding the susceptibility levels of these species. The study was designed to determine the susceptibility levels of Cx.

Current Susceptibility Status of (Diptera: Culicidae) to Different Imagicides in a Malarious Area, Southeastern of Iran.

Background: mosquitoes are an important group of arthropods due to their role in transmission of malaria. The present study was conducted for determination of susceptibility status of to different imagicides collected from malarious area in Chabahar city, Iran.

Methods: In the present study seven insecticides including: DDT 4%, lambdacyhalothrin 0.

High Insecticides Resistance in (Diptera: Culicidae) from Tehran, Capital of Iran.

Background: During recent years transmission of (dog heart worm) by and West Nile virus have been reported from Iran. The present study was preformed for evaluating the susceptibility status of collected from capital city of Tehran, Iran.

Methods: Four Insecticides including: DDT 4%, Lambdacyhalothrin 0.

Irritability Levels of Field and Laboratory Population of Culex pipiens Complex in Tehran to Different Groups of Insecticides.

Background: The irritant effect of some insecticides can cause a proportion of mosquitoes to leave the sprayed rooms before acquiring a lethal dose, so the repeated contact al sub-lethal dose may lead to extent the resistance.

Methods: Larvae and pupae of Culex pipiens complex were collected in mass from open canals of waste water in capital city Tehran and reared to obtain the first generation at laboratory. Sugar-fed 2-3 days female mosquitoes were used for the experiments and compared with laboratory strain.

Chemical Composition, Larvicidal and Repellency Properties of Cionura erecta (L.) Griseb. Against Malaria Vector, Anopheles stephensi Liston (Diptera: Culicidae).

Background: Application of plant derivatives have been suggested as alternative sources for mosquito control.

Methods: The root essential oil and methanol extract of Cionura erecta (L.) Griseb was tested under laboratory conditions for larvicidal and skin repelleny activities against Anopheles stephensi.

Baseline Susceptibility of Different Geographical Strains of Anopheles stephensi (Diptera: Culicidae) to Temephos in Malarious Areas of Irana.

Background: Malaria still remains a public health problem in Iran. There are different vector control interventions such as insecticide spraying. The present study was carried out to determine the susceptibility status of Anopheles stephensi larvae to temephos as a national plan for monitoring and mapping of insecticide resistance.

Wash Resistance and Bioefficacy of Alpha-cypermethrin Long Lasting Impregnated Nets (LLIN-Interceptor(®)) against Anopheles stephensi using Tunnel Test.

Background: The Long-lasing insecticide impregnated nets (LLINs) is considered as an effective tools for malaria vector control. The aim of this study was to evaluate the residual efficacy of alpha-cypermethrin long lasting impregnated nets (LLIN-Interceptor(®)) against Anopheles stephensi using tunnel test.

Methods: The wash-resistance of Interceptor(®) nets were assessed under laboratory conditions using tunnel test.
