background: human malaria remains a major malady in eastern iran. vector control interventions such as indoor residual spraying are used to fight with the disease. this study was undertaken to determine the lethal and residual effects of three different pyrethroid insecticides on adult mosquitoes of anopheles stephensi on different surfaces in iran, as part of a national program to monitor inse...

This article presents the development of a multiresidue method for the estimation of 30 insecticides, 15 organochlorine insecticides and 6 organophosphorus insecticides, 9 synthetic pyrethriods and 2 herbicides and their quantification in vegetables. The monitoring study indicates that though all the vegetable samples were contaminated with pesticides, only 31% of the samples contained pesticid...

The response of adult females of the mosquito Culex pipiens molestus to six insecticides was evaluated. Adults were collected from two locations in the Amman area from May to October 1983. The F1 generation was exposed to paper-impregnated insecticides using WHO test kits. At both locations, the most toxic insecticides were permethrin, propoxur and ferpropathrin. Malathion, dieldrin and DDT wer...

Insect pests are responsible for human suffering and financial losses worldwide. New and environmentally safe insecticides are urgently needed to cope with these serious problems. Resistance to current insecticides has resulted in a resurgence of insect pests, and growing concerns about insecticide toxicity to humans discourage the use of insecticides for pest control. The small market for inse...

Seven insecticides, viz. Megamos 20SL, Actara 25WG, Polo 500SC, Sitara 25WP, Nighaban 20EC, Thiodan 35EC and Confidor 200SL were evaluated at their field recommended doses for their efficacy against whitefly (Bemisia tabaci Genn.) on cotton, at the farmer’s field in Dera Ghazi Khan during 2007. The insecticides were applied at ETL’s of whitefly. All the test insecticides caused significant mort...

habrobracon hebetor say (hymenoptera: braconidae) as an ectoparasitoid of larval stage of lepidopterous pests is widely used in biological control programs. in the present research, the effect of field recommended doses of imidacloprid, indoxacarb and deltamethrin were studied on life table parameters of h. hebetor in pupal stage treatment. one hundred, two-day-old pupae were treated with 1 mic...

As with other insects, resistance to insecticides has become a limiting factor in the use of insecticides to control mosquitoes. Mosquito control depended on the use of insecticides for a long time (initially organochlorines, followed by organophosphates, carbamates and pyrethroids). This study aimed to determine the susceptibility of Anopheles arabiensis adult to the public health and agricult...

The effective management of emerging insect-borne disease is dependent on the use of safe and efficacious chemical insecticides. Given the inherent ability of insects to develop resistance, it is essential to propose innovative strategies because insecticides remain the most important element of integrated approaches to vector control. Recently, intracellular phosphorylation and dephosphorylati...

the residual activity and air-borne efficacy of etofenprox (trebon 20% wp) were studied on different surfaces in hut scale trial, in kazeroun south of iran, in 1992. the bio-assay contact mortality tests with trebon against anopheles stephensi showed similar responses on pluster, cement and mud surfaces (except wooden surfaces), i.e. at 250, 400 and 500 mg/m2, trebon had residual activity for a...

the first records of anopheles fluviatilis resistance to ddt was reported in 1963 from india and to dieldrin from eastern saudi arabia in 1959. in southern iran, antimalaria measures began in 1950 and up to 1957 the area was under ddt residual house spraying at the rate of 2g /m2 one round/year. during 1958-59 dieldrin was used at 0.5 g/m2, 1or 2 rounds/year was applied in the lowland areas. in...
