title: [Pruriginous dermatitis due to Pyemotes zwoelferi Krczal, 1963. About several cases in the Alpes-Maritimes (France) (author's transl)].
abstract: In September 1978, people having had contacts in the neighbouring of Nice with an everlasting flower package (Helichrysium angustifolium) from Jugoslavia, complained of prurigo. The erythematous lesions with a central vesicle regressed during the second week but did not fade out until the third week. Among the everlasting flowers were found numerous and swiftly mowing fasting females of Pyemotes zwoelferi. Those mites are usually parasitic on phytopathogenic insects. Their aggressiveness against human beings is related to sudden development of their population and, also to the specific toxicity of their venom. Systematically P. zwoelferi comes in the same species group as P. tritici.
