Four acaricides (amitraz, cyfluthrin, permethrin, and pyrethrins) were studied for their efficacy in the rapid killing of Amblyomma americanum, A. cajennense, and A. maculatum (Acari: Ixodidae) and eight acaricides (amitraz, carbaryl, chlorpyrifos, cyfluthrin, fipronil, permethrin, pyrethrins, and selamectin) for their efficacy in the rapid killing of Rhipicephalus sanguineus (Acari: Ixodidae)....

Given the widespread use of insecticides in the environment, it is important to perform studies evaluating their potential effects on humans. Organophosphate insecticides, such as chlorpyrifos, are being phased out; however, the use of pyrethroids in household pest control is increasing. While chlorpyrifos is relatively well studied, much less is known about the potential neurotoxicity of cyflu...

Toxic and feeding inhibition effect of cyfluthrin treated nets was assessed and compared with the activity of deltamethrin impregnated nets, before and after 2 and 4 washes against Phlebotomus papatasi. Impregnated cyfluthrin nets (50, 25, 12.5 mg active ingredient (a.i.)/m2) caused knock down and mortality rates higher than 90%, being of 100% at the highest dose, while the nets impregnated wit...

Pyrethroid insecticides and heavy metals frequently co-exist in aquatic systems, due to intensive anthropogenic activities, their effects on organisms are needed be investigated. In the present work, single combined of environmentally realistic concentrations cyfluthrin copper digestive gland histology freshwater pond snail (Lymnaea stagnalis) were evaluated. Snails exposed 1 µg/L cyfluthrin, 1...

Cyfluthrin was evaluated in the field as a residual insecticide to develop a new strategy for control of Old World phlebotomine sand fly vectors of leishmaniasis, which live and rest inside termite mounds and animal burrows. This insecticide was evaluated as a residual spray in Baringo District, Kenya, during 1993. Termite mounds and animal burrows were treated with a cyfluthrin/corn oil mixtur...

Use of pyrethroid pesticides, which are highly toxic to aquatic organisms, has increased substantially over the past decade. In 2006, the pyrethroid pesticides cyfluthrin and permethrin were measured in Sacramento-San Joaquin (SSJ) Delta (CA, USA) water at 5 and 24 ng/L (pptr), respectively. To elucidate any interactions between the two pyrethroids, a 10-d laboratory exposure was performed with...

The lesser mealworm, Alphitobius diaperinus (Panzer), is an important pest in poultry facilities. The toxicity of cyfluthrin and tetrachlorvinphos to five strains of the lesser mealworm was compared with the toxicity to a susceptible laboratory strain. Bioassays were carried out with both larvae and adults. For the susceptible strain, cyfluthrin and tetrachlorvinphos had similar toxicity to adu...

To further elucidate the possible involvement of intracellular protein catabolism in the development of insecticide resistance, we determined in vivo effect of the potent synthetic pyrethroid, ß-cyfluthrin on the activities of cytoplasmic and lysosomal proteolytic enzymes in insecticide-resistant and susceptible strain of housefly, Musca domestica. ß-Cyfluthrin at LC50 dose after 48 hour treatm...

Cyfluthrinm[cyano[4-fluoro-3-phenoxyphenyl]-methyl-3-[2,2-dichloroethenyl]-2,2-dimethyl-cyclo propane carboxylate] is a synthetic pyrethroid insecticide, that has both contact and stomach poison action. The present study evaluated the long-term toxic effects of cyfluthrin on antioxidant status in buffalo calves. Oral administration of cyfluthrin at a dose rate of 10 and 20 mg/kg/d for 11 consec...

Environmental pollution by pesticide residues is a major environmental concern due to the extensive use of these substances in agriculture. The insecticide beta-cyfluthrin is a synthetic pyrethroid widely used in agricultural and other domestic activities. The aim of the present study was to assess the genotoxic effects of a sublethal exposure of the fish Bryconamericus iheringii (Characidae) t...
