susceptibility tests were carried out on anopheles stephensi with d.d.t(4%), dieldrin (4%), malathion(5%), propoxus (0.1%), primphos-methyl (o.lmg/cm2), lambda-cyhalothrin (0.1%), permethrin (0.25%) and deltamethrin (0.025%) during 1990-94 in minab county, soutern iran, using w.h.o standard method. results showed that an. stephensi was susceptible to malathion, propoxur, primphos - methyl, lamb...

malaria has recently been resurged in some parts of iran which is bordered with armenia, naxcivan and turkey. an attempt was made to asses the current status of insecticide resistance in the main malaria vector , an.sacharovi. adult engorged mosquitoes were collected from dwellings during the seasonal activity of the vector, which is synchronized in summer 2001. mosquitoes were subjected to the...

the aim of this study was to determine the environmental risk of pesticide a.i. applied to control insects and fungus in cereal farming in sanliurfa, turkey. in 2013, 8 active ingredients (a.i.) in cereal farming were applied for insect and fungus control in sanliurfa, turkey. these a.i. were alpha-cypermethrin(ec), chlorpyrifos(ec;wp), difenoconazole(ec), indoxacarb(wg), lambda-cyhalothrin(ec)...

BACKGROUND Understanding the feasibility of achieving widespread coverage with Insecticide-Treated Nets has to be preceded by learning how people value the Insecticide-Treated Nets and estimating the potential demand and willingness to pay so that sustainability of the intervention can be assured. The objective of this study was to determine willingness to pay for Insecticide-Treated Nets among...

Coptotermes formosanus workers were treated topically with insecticide and subsequently held individually or in groups to examine possible effects on insecticide toxicity. Chlorpyrifos, cypermethrin and chlordane toxicities were 1.4-, 1.5-, and 1.3-fold greater, respectively, among workers held in groups compared with those held individually after insecticide treatment. Experiments were conduct...

Competition is a driving force regulating communities often considered an intermittent phenomenon, difficult to verify and potentially driven by environmental disturbances. Insecticides are agents of environmental disturbance that can potentially change ecological relationships and competitive outcomes, but this subject has seldom been examined. As the co-existing cereal grain beetle species Si...

background: malaria is the most important vector-borne disease in many tropical countries all over the world. because of the widespread use of pyrethroid insecticide treated mosquito nets in the world, the effects of excito-repellency (er) phenomenon of pyrethroids against main malaria vector, anopheles stephensi were studied. methods: the er phenomenon of three concentrations of two synthetic ...

The performance of five insecticides (bendiocarb, deltamethrin, DDT, malathion, and imidacloprid) using three application methods (oil-based insecticide films on filter paper, and acetone-based insecticide deposits on two substrates: filter paper and glass) was assessed against a susceptible strain of Cimex lectularius (L.) and two resistant strains of Cimex hemipterus (F.). Substrate type sign...
