“…While adults of many Lepidoptera lose the irritating hairs at emergence, females of a few taxa are able to take up the poisonous hairs and cover their eggs with them. Females of the lymantriid genera Euproctis and Acyphas cover their eggs with venomous hairs obtained from the cocoon (Pesce and Delgado, 1971;Kawamoto and Kumada, 1984). The hairs of Euproctis are known to contain histamine ( Figure 3-2, [l]), and enzymes such as esterase, protease, and phospholipase A2 de Jong et al, 1982;Kawamoto and Kumada, 1984).…”

“…Estas liberan setas urticantes en el ambiente que al contacto con la piel causan dermatitis y prurito intenso en el hombre, por lo cual es considerada un problema de salud pública. En ciertos casos los síntomas están acompañados por una fuerte reacción alérgica, y se ha reportado inclusive trastornos respiratorios, fi ebre, dolor de cabeza, náuseas, queratitis y conjuntivitis, entre otros (Pesce & Delgado 1971, Benain-Pinto et al 1991, Rodríguez et al 2005. En algunos casos de altas poblaciones de la polilla, se produce inclusive la interrupción de la mayoría de las actividades sociales y económicas, especialmente la producción y exploración petrolera, pesca, agricultura, educación y el comercio en general.…”

-The moth Hylesia metabusCramer is considered a public health pest due to the release of urticating hairs by adult females during periodic invasions of towns and villages, producing dermatits in humans. We reported natural parasitism levels for this moth during six life cycles in two localities in northeastern Venezuela. Pupae were collected in the fi eld and maintained under laboratory conditions (27°C, 65% RH, 12L:12D photoperiod) until eclosion. In Mapire, parasitism increased from 33.0% to 91.1% in the three cycles studied, with the dipterans Belvosia spp. (Tachinidae) and Sarcodexia lambens Wiedemann (Sarcophagidae) and species from Ichneumonidae, Chalcidae, Perilampidae and Eulophidae being the most common. In Pedernales, parasitism decreased from 29.5% to 16.1%, and Belvosia spp. was the most abundant parasitoids, reaching parasitization levels between 70.7% and 96.2%. A signifi cative parasitization by Neotheronia sp. (Hymenoptera: Ichneumonidae) (27.1%) occurred only in third life cycle. All natural enemies observed were koinobionts, larval-pupa parasitoids. The variations in the populations of H. metabus and its parasitoids in the areas studied are discussed. Belvosia spp. and S. lambens may have potential for use in integrated management program of H. metabus.KEY WORDS: Parasitism, Tachinidae, Sarcophagidae, Hymenoptera, urticating hair RESUMEN -Hylesia metabus Cramer es una polilla considerada un problema de salud pública debido a que las hembras adultas liberan setas urticantes produciendo dermatitis y prurito intenso en el hombre. En la región nororiental de Venezuela, en dos localidades (Mapire y Pedernales) y durante seis ciclos, se registró el parasitismo natural sobre esta polilla. Para ello, se colectaron pupas en el campo y se mantuvieron bajo condiciones de laboratorio (27ºC, 65% humedad relativa y ciclo invertido 12L:12O) hasta la eclosión de los adultos. Se determinó que en Mapire el parasitismo aumentó de 33,0% a 91,1% en tres ciclos consecutivos estudiados y los principales parasitoides fueron los Diptera: Belvosia spp. (Tachinidae) y Sarcodexia lambens (Sarcophagidae) y diversas especies de Hymenoptera (Ichneumonidae, Chalcidae, Perilampidae, Eulophidae). En Pedernales en tres ciclos consecutivos el parasitismo disminuyó de 29,5% a 16,1%, el parasitoide más abundante fue Belvosia spp., con niveles de parasitismo entre 70,7% y 96,2%. Solamente durante el tercer ciclo, la contribución de otro parasitoide resultó signifi cativa y correspondió a Neotheronia sp. (Hymenoptera: Ichneumonidae), que causó 27,1% de parasitismo. Todos los parasitoides obtenidos fueron koinobiontes larva-pupa. Las variaciones poblacionales de H. metabus y sus parasitoides en las áreas estudiadas son discutidas. Belvosia spp. y Sarcodexia lambens son potenciales parasitoides a ser usados en programas de manejo integrado de este insecto plaga.
