title: [Epidemic outbreaks of dermatitis caused by butterflies of the genus Hylesia (Lepidoptera: Hemileucidae) in São Paulo State, Brazil].
abstract: Epidemic outbreaks of dermatitis caused by Hylesia sp which occurred in the coastal region of the State of S. Paulo during the period of December 1989 to December 1991 are confirmed. The incident assumed its greatest intensity in Bertioga, in Santos County, where 612 cases were registered. The outbreak also affected 12 other counties in that region and it was estimated that hundred of affected persons sought the Local Health Service Care. The majority presented with erythematous and prutiginous lesions and papula which lasted 7 to 14 days on average. Treatment consisted of systemic administration of antihistamines, and the use of topic corticosteroids and cold compresses. During the above-mentioned period, three epidemic episodes, coinciding with the rainy season (November to January), occurred. They were first observed in the northern part of the coastal area and then spread to the south. Information as to how avoid contact with the moth was the main prophylactic measure. In highly infested buildings the effectiveness of residual insecticide procedure was used in the attempt to reduce the level of moth infestation. Satisfactory results were obtained with deltametrin applied in a dosage of 50 mg/m2 of wall.
