A recent study supported by the NPA and the MAES Hatch
Grant has been published in Pesticide Biochemistry and Physiology 66, 130-143, 2000.
This study has reinforced earlier findings by identifying permethrin resistance
in various strains of head lice.
Perhaps most important in this work is
the trail blazing research that will enable resistance in lice to be identified
by genetic mutations rather than the tedious and often difficult collection of
live lice and assay method. Thanks to this research, it is now
possible to identify resistance efficiently and objectively, allowing for
routine monitoring and early identification of resistance problems.

Analysis of kdr-like Resistance in Permethrin-Resistant Strains of Head
Lice, Pediculus capitis, can be obtained at
