I think you may get some help from some former colleagues of mine at 
Rothamsted Research Station, Harpenden, Herts., U.K. The original 
pyrethroid insecticides were developed there some years ago.
Possibly Norman Janes or Bupinder Khambay, who work in that group, are 
possible sources. I don't have e-mail addresses, but you may be able to 
find them. They will be something like "????"
Best of luck.
