“…It was described again by Boyé (1932) in Guiana and received the status of estival epidemics in Argentina by Jörg (1933). According to Hill et al (1948) such dermatitis also had periodical notoriety due to many accidents which happened to crews on oil tankers that called at the fluvial port of Caripito and surroundings in Venezuela, when thousands of moths of Hylesia urticans Floch and Abonnenc, 1944, nowadays Hylesia metabus Cramer, 1775, (Lemaire, 2002 were attracted by the lights of the boats causing serious dermatitis. It was so serious that it caused union conflicts and was acknowledged as a labor disease.…”

The aim of this work was to study biological aspects and the life cycle of Hylesia Metapyrrha in a laboratory. Laboratorial breeding was made at 25 ± 1 °C, 70 ± 10% UR and 14 hours of photophase, feeding the larvae with guava leaves (Psidium guayava L. -Myrtaceae). Time was evaluated on the days of all the development stages; morphometry was evaluated in millimeters and the pupa's mass in grams. The eggs were disposed in groups and covered by urticating abdominal hair. The incubation period lasted 52 days. The larvae, with gregarious habits, presented background black coloration, yellowish scoli and two orange longitudinal lines above and below the spiracles, during the development which lasted an average period of 74.59 days and went through seven instars. The pre-pupa and the pupa stages lasted on average 8.82 and 50.56 days, respectively; the female pupae presented a duration, weight and size which was significantly bigger. The adult stage lasted on average 5.50 days with periods of pre, post and oviposition of 2.30, 1.90 and 1.00 days, respectively. This study broadens the knowledge of the immature stages, biological, morphological and behavioral aspects, until then restricted to the morphology and to registers of the occurrence of the adult forms.Keywords: Biology, dermatitis, entomology, erucism, lepidopterism.Aspectos biológicos de Hylesia metapyrrha Walker (Lepidoptera; Saturniidae; Hemileucinae), em laboratório Resumo O presente estudo objetivou estudar aspectos biológicos e o ciclo de vida de Hylesia metapyrrha em laboratório. Para tanto, foi realizada uma criação laboratorial a 25 ± 1 °C, 70 ± 20% UR e 14 horas de fotofase, alimentando-se as lagartas com folhas de goiabeira (Psidium guajava L -Myrtaceae). Para todas as fases de desenvolvimento, foram avaliados o tempo em dias, a morfometria em milímetros e, para as pupas, a massa, em gramas. Também foram feitas observações sobre características morfológicas e etológicas. Os ovos, de formato subcilíndrico, são dispostos em grupos e recobertos por cerdas abdominais urticantes, o período de incubação foi de 52,00 dias. As lagartas, de hábito gregário, apresentam coloração de fundo negra, escolos amarelados e duas linhas longitudinais laranja dispostas acima e abaixo dos espiráculos, durante o desenvolvimento que teve um período médio de 74,59 dias, passaram por sete ínstares. As fases de pré-pupa e pupa duraram em média 8,82 e 50,56 dias, respectivamente, sendo que as pupas do sexo feminino apresentaram duração, peso e tamanho significativamente maiores que as dos machos. A fase adulta durou em média 5,50 dias, com períodos de pré, pós e oviposição de 2,30, 1,90 e 1,00 dias, respectivamente. Este estudo amplia os conhecimentos sobre as fases imaturas, aspectos biológicos, morfológicos e comportamentais até então restritos apenas à morfologia e registros da ocorrência das formas adultas.Palavras-chave: Biologia, dermatite, entomologia, erucismo, lepidopterismo.

“…Potent topical glucocorticoids applied for a short time are helpful for intensely pruritic lesions. In some cases, a short tapered course of oral glucocorticoids such as dexamethasone or prednisone 29 can be given for persistent cutaneous reactions 33 . Systemic intramuscular triamcinolone acetonide has been successfully used in the treatment of pain and dermatitis 29 .…”

“…28 It is generally known that topical application of analgesics, antibiotics, and antihistamines are of little value in dermatitis caused by Hylesia. 29 However, physical measures such as the use of cold compresses and calamine lotions can provide partial symptomatic relief. 9,11,25 It has been demonstrated that the use of warm compresses impregnated with sodium bicarbonate as well as local use of tetracaine unguents are helpful for relief of symptoms.…”
