τ-Fluvalinate is a pyrethroid acaricide.1It induces tail currents in Western honeybee (A. mellifera) voltage-gated sodium channels (AmNav1) expressed inXenopusoocytes (EC50= 60 nM). It also induces tail currents in honeybee parasitic Varroa mite (V. destructor) Nav1 channels (VdNav1) expressed inXenopusoocytes (EC50= 160 nM) with a faster tail current decay than that of AmNav1 channels. Topical application of τ-fluvalinate (2 μl) in combination with coumaphos , atrazine , 2,4-DMPF, chlorpyrifos , and chlorothalonil does not affect honeybee queen mass, egg-laying patterns, or the mass of daughter worker bees at emergence.2Formulations containing τ-fluvalinate have been used to control Varroa mites in beehives.

DMSO/Ethanol/DMF
| |||||||||||||||||||||
Dissolve 2 mg of the compound in 100 μL DMSO
to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO
stock solution to 400 μL PEG300
and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O
and mix thoroughly until a homogeneous solution is obtained.
