Notes: Bifenthrin is a synthetic pyrethroid insecticide that prolongs opening of sodium channels resulting in membrane depolarization and conductance block in the insect nervous system.{36375} It is effective against A. gambiae and C. quinquefasciatus mosquitos (LD50s = 0.15 and 0.16 ng/mg, respectively) and increases O. insidiosus mortality in treated corn and sorghum plants.{41760,41761} Bifenthrin exhibits aquatic toxicity, inducing reproductive defects and lethality in D. magna (LC50 = 12.4 µg/L).{41762} Acute oral administration of bifenthrin induces fine tremor, decreases motor activity and grip strength, and increases pawing and head shaking behaviors in rats, indicating typical Type I pyrethroid neurotoxicity.{41763} Bifenthrin (8 mg/kg) also decreases locomotor activity, induces anemia, elevates white blood cell counts, alanine transaminase (ALT), and superoxide dismutase (SOD), as well as decreases glutathione peroxidase (Gpx) activity in mice.{41764} Formulations containing bifenthrin have been used as insecticides in residential and agricultural settings.
