Aucula magnifica (Schaus, 1904) (Lepidoptera: Noctuidae: Agaristinae): morphology of egg and last instar larvae

Abstract

Aiming to contribute to knowledge of the immature instars of Neotropical Lepidoptera, this study details the morphology of the egg and last instar larvae of Aucula magnifica (Schaus, 1904) (Lepidoptera: Noctuidae: Agaristinae), emphasising the structures of the corium and the chaetotaxy. There is also a report of the occurrence of entomopathogenic action of Nomuraea rileyi (Farlow) Samson fungi on the larva.Keywords: caterpillar, entomopathogenic fungi, morphology, chaetotaxy.Aucula magnifica (Schaus, 1904) (Lepidoptera: Noctuidae: Agaristinae): morfologia do ovo e da larva de último ínstar ResumoEste estudo objetiva contribuir para o conhecimento dos estágios imaturos dos lepidópteros neotropicais. Nele é feito o detalhamento da morfologia das fases de ovo e de larva de Aucula magnifica (Schaus, 1904) (Lepidoptera: Noctuidae: Agaristinae), dando ênfase ao estudo das estruturas do córion e da quetotaxia da larva de último ínstar. Além disso é relatada a ocorrência da ação entomopatogênica do fungo Nomuraea rileyi (Farlow) Samson sobre suas larvas.Palavras-chave: lagarta, fungo entomopatogênico, morfologia, quetotaxia.

Infestation of Portulaca oleracea (Portulacaceae) plants by Neotuerta platensis (Lepidoptera: Noctuidae) larvae in Brazil: evaluations for five consecutive years

“…The high variation in the number of eggs and egg masses per female and without covering its eggs with pubescence by N. platensis is characteristic of noctuids, such as Aucula franclemonti Todd &Poole, 1981 andAucula magnifica (Schaus, 1904) (Lepidoptera: Noctuidae) in the laboratory on plants of Vitis labrusca L. (Vitaceae) in Bento Gonçalves, Rio Grande do Sul State (Poletto et al, 2010). The duration of the pupa stage of N. platensis was similar to that of other noctuid species, such as the velvet armyworm, Spodoptera cosmioides Walker, 1856 (Lepidoptera: Noctuidae) fed with plants of P. oleracea in laboratory in Planaltina, Distrito Federal, Brazil (Specht and Roque-Specht, 2016).…”
