Biological aspects of Dirphia moderata (Lepidoptera: Saturniidae) on Eucalyptus cloeziana and Psidium guajava

Abstract

An egg mass of Dirphia moderata Bouvier was collected around a branch of

Desenvolvimento e reprodução de Dirphia moderata (Lepidoptera: Satutniidae) em Eucalyptus cloeziana e Psidium guajava em laboratório

“…Além disso, essa última espécie foi relatada em 700 ha, com desfolha total de 300 ha de Eucalyptus grandis Hill ex Maiden e E. saligna na região de Buritizeiro, Minas Gerais (ZANUNCIO, 1993). Dirphia moderata Bouvier, 1919 (Saturniidae) (PEREIRA et al, 2008), coletada em Montes Claros, Minas Gerais, foi criada em Eucalyptus urophylla (ZANUNCIO et al, 1994) e relatada como D. avicula, sendo essa sinonímia corrigida após uma revisão desse gênero. Uma espécie próxima, Pseudodirphia (Dirphia) eumedidoides (Vuillot, 1892), foi estudada (SANTOS et al, 1993).…”

Observaciones del parasitismo de Palmistichus elaeisis (Hymenoptera: Eulophidae) sobre pupas de Quadrus cerialis (Lepidoptera: Hesperiidae) en Piper reticulatum (Piperaceae) en la Reserva Biológica Dr. Rodrigo Tarté, Ciudad del Saber, Panamá.

“…Esta especie es un endoparasitoide polífago gregario, se ha encontrado parasitando especies de lepidópteras nativas e introducidas (Tavares et al, 2011). También, se puede desarrollar en pupas de lepidópteros de las familias Arctiidae (Pereira et al, 2008), Bombycidae (Pereira et al, 2010;Crambidae Bittencourt y Berti-Filho, 2004;Chichera et al, 2012), Lymantriidae (Tavares et al, 2011;Zaché et al, 2012), Noctuidae (Bittencourt y Berti-Filho, 2004;Andrade et al, 2010;Pereira et al, 2013), Nymphalidae (Tavares et al, 2013a), Notodontidae (Zanuncio et al, 2015), Papilionidae (Tavares et al, 2013b), Saturniidae (Pereira et al, 2008); en algunas especies como Thyrinteina arnobia (Stoll, 1782) y Thyrinteina leucoceraea (Rindge, 1961) (Geometridae), estas dos especies asociadas a cultivos de plantas de Eucalipto. También, se desarrolla en pupas de coleópteros de la familia Tenebrionidae (Zanuncio et al, 2008) y pupas de moscas Muscidae (Zaché et al, 2013).…”

Bionomic Aspects of <em>Cerodirphia opis</em> (Schaus, 1892) (Lepidoptera: Saturniidae, Hemileucinae) and Identification of Its Natural Enemies

“…The sex ratio of this insect was also 0.48 in E. urophylla, which demonstrates that eucalyptus species do not change this biological aspect. Pereira et al [17] found a higher sex ratio of 0.48 and 0.46 for adults obtained with larvae fed by E. cloeziana and P. guajava. Pereira et al [25] who obtained a sex ratio of 0.59 for Hylesia paulex and Specht et al [16], observed a sex ratio of 0.505 for A. illustris, that is, about twice the number of females obtained in the present work.…”

“…The larvae of C. opis started the pupation on 08/X/2019, therefore 23 days after field collection. Pupation usually occurs within a cocoon of silk stuck to dry leaves found in the substrate in the work by Pereira, et al [17] who performed the biology of a Saturnidae, the duration (days) and larval viability (%) of D. moderata were 53.00 ± 0.09 and 80.00 ± 0.99 and for larvae of this species reared with E. cloeziana with six instars. The fully sclerotized cuticle does not expand, therefore, the growth of hard parts only occurs when there is a "mute", when a new one cuticle is produced and expanded.…”
