High-Resolution Genetic Mapping Combined with Transcriptome Profiling Reveals That Both Target-Site Resistance and Increased Detoxification Confer Resistance to the Pyrethroid Bifenthrin in the Spider Mite Tetranychus urticae
Biology (Basel)
SIMPLE SUMMARY: The two-spotted spider mite Tetranychus urticae is an important pest on agricultural crops worldwide. The widespread application of pyrethroid acaricides—such as bifenthrin—to control this pest has resulted in the development of r...

Nanomolar Bifenthrin Alters Synchronous Ca(2+) Oscillations and Cortical Neuron Development Independent of Sodium Channel Activity
Mol Pharmacol
Bifenthrin, a relatively stable type I pyrethroid that causes tremors and impairs motor activity in rodents, is broadly used. We investigated whether nanomolar bifenthrin alters synchronous Ca(2+) oscillations (SCOs) necessary for activity-dependent ...

Stimulation of Erythrocyte Membrane Blebbing by Bifenthrin Induced Oxidative Stress
Dose Response
BACKGROUND: Bifenthrin is an insecticide and anti-estrogenic compound primarily used to control residential pests by depolarizing sodium gated voltage channels in the nervous system. Eryptosis, the suicidal death of erythrocytes, featured by PS expos...

Bifenthrin Diminishes Male Fertility Potential by Inducing Protein Defects in Mouse Sperm
Toxics
A synthetic pyrethroid pesticide, bifenthrin, has been commonly used as an effective exterminator, although the rise in its usage has raised concerns regarding its effects on the environment and public health, including reproduction, globally. The cu...

Pyrethroid neurotoxicity studies with bifenthrin indicate a mixed Type I/II mode of action
Pest Manag Sci
BACKGROUND: Bifenthrin is usually considered a Type I pyrethroid, because it lacks an α‐CN group present in Type II pyrethroids, but some previous studies suggest a mixed Type I/II mode‐of‐action. Results are presented for bifenthrin in a rat ...

Microbial Detoxification of Bifenthrin by a Novel Yeast and Its Potential for Contaminated Soils Treatment
PLoS One
Bifenthrin is one the most widespread pollutants and has caused potential effect on aquatic life and human health, yet little is known about microbial degradation in contaminated regions. A novel yeast strain ZS-02, isolated from activated sludge and...

The Use of Non-targeted Lipidomics and Histopathology to Characterize the Neurotoxicity of Bifenthrin to Juvenile Rainbow Trout (Oncorhynchus mykiss)
Environ Sci Technol
[Image: see text] Due to the detection frequencies and measured concentrations in surface water, the type I pyrethroid insecticide, bifenthrin, has been of particular concern within the Sacramento-San Joaquin Delta in California. Concentrations have ...

Transcriptomic and Histopathological Effects of Bifenthrin to the Brain of Juvenile Rainbow Trout (Oncorhynchus mykiss)
Toxics
The increased global use of pyrethroids raises concern for non-target aquatic species. Bifenthrin, among the most predominantly detected pyrethroids in the environment, is frequently measured in water samples above concentrations reported to induce n...

Correlation of tissue concentrations of the pyrethroid bifenthrin with neurotoxicity in the rat
Toxicology
The potential for human exposure to pyrethroid pesticides has prompted pharmacodynamic and pharmacokinetic research to better characterize risk. This work tested the hypothesis that blood and brain concentrations of the pyrethroid bifenthrin are pred...

Bifenthrin causes transcriptomic alterations in mTOR and ryanodine receptor-dependent signaling and delayed hyperactivity in developing zebrafish (Danio rerio)
Aquat Toxicol
Over the last few decades, the pyrethroid insecticide bifenthrin has been increasingly employed for pest control in urban and agricultural areas, putting humans and wildlife at increased risk of exposure. Exposures to nanomolar (nM) concentrations of...

Sub-Lethal Effects of Bifenthrin and Imidacloprid on Megacephala carolina carolina L. (Coleoptera: Carabidae) in Turfgrass
Insects
SIMPLE SUMMARY: Tiger beetles are important predators in turfgrass in Georgia, USA. Many insecticides are sprayed on turfgrass to manage pests. Among them, bifenthrin and imidacloprid are the most commonly used insecticides in turfgrass. These insect...

Preparation of biodiesel oil-in-water nanoemulsions by mixed surfactants for bifenthrin formulation
RSC Adv
Although several approaches have been reported on the development of nanoemulsions over the last few years, studies on the formation of biodiesel nanoemulsions for bifenthrin formulation by the low-energy phase inversion composition (PIC) method are ...
