Three species of the family Phyllodocidae and two of Hesionidae were found in colonies of the bryozoan Schizoporella unicornis (Johnston) on the beaches of Ubatuba and São Sebastião, São Paulo State, Brazil. Among these, Eumida sanguinea (Phyllodocidae) is registered for the first time on the Brazilian coast. Among the other species Ophiodromus pugettensis (Hesionidae) was one of the most abundant polychaetous annelids of the bryzoan fauna.Resumo em Inglês:
Natural occurrence of nuclear polyhedrosis viruses were detected in populations of some Heliconiini in the field as well as in the laboratory. The epizootics appeared under field conditions in populations of Dione juno juno, D. moneta and Agraulis vanillae maculosa. In the laboratory, however, larvae of Heliconius numata mirus, H. hecale vetustus and H. erato phyllis in addition to two hybrids and Eueides Isabella dianasa, all suffered the same disease. The effect of several factors which might contribute to the occurrence of the disease are discussed. Symptoms, histopathology and description of viral particles and polyhedra are given.Resumo em Inglês:
