Aldrich doesn't list Tedion (A.K.A. 2,4,4',5-TetraChloroDiphenyl Sulfone) in its catalogue, but if you call their Rare Chemicals department, you can found out how much they currently have available. It is currently listed in the company computers, with catalogue number S42834-5 for five grams, and sells for $35 (their minimum price for rare chemical orders). Good luck with it. I've tried to use it recently against an infestation of what appear to be Histiostoma mites (but without the hypopal stage that drives the flies and us crazy). The mites ignore the paper impregnated with the Tedion. Oh, well ... Ian Boussy Biology, Loyola University .
