Adeloneivaia schubarti Rêgo Barros & Mielke e seus estágios imaturos (Lepidoptera, Saturniidae, Ceratocampinae)

Abstract

Neste trabalho descreve-se pela primeira vez os estágios imaturos desta espécie. Imaturos e adultos são ilustrados a cores, e a traço (primeiro ínstar e pupa). MATERIAL E MÉTODOSDiversas possíveis plantas hospedeiras foram oferecidas às larvas, que imediatamente aceitaram Stryphnodendron adstringens (Mart.) Coville (Leguminosae-Mimosoideae). Parte das larvas foi criada em caixas plásticas no laboratório, e parte em viveiros de tela plástica, montados sobre ramagens vivas na planta hospedeira. Estas últimas tiveram um desenvolvimento mel hor, foram mais saudá-veis, e proporcionaram imagos com tamanho maior e melhor aparência, a maioria dos quais foi liberada na natureza com o objetivo de manter e ampliar o equilíbrio populacional da espécie. (Fig. 1) Elipsóide com as duas faces fortemente achatadas e com a área central côncava. Face maior verde-clara translúcida; a menor verde-amarelada. Comprimento: 2,2 mm; largura: 2,0 mm; espessura: 1,0 mm . Período embrionário: sete dias . RESULTADOS Ovo

Immature Stages ofAdeloneivaia fallax(Lepidoptera: Saturniidae)

“…The duration of the final larval feeding period was roughly the same for both species. Other behavioral characteristics of A. fallax resembled some notes on A. schubarti by Furtado (2001).…”

“…The egg of A. fallax does not differ greatly from eggs of other Ceratocampinae, such as A. schubarti, P. walkeri and M. pulchra, sharing with these species the greenish coloration and discoidal shape (Furtado 1999(Furtado , 2000(Furtado , 2001. As far as we know, the present study is the first detailed description of the egg ultrastructure of a ceratocampine moth.…”

“…Pupation occurred in the soil, without a well-defined pupal chamber. Similar behavior was observed in A. schubarti and Megaceresa pulchra (Bouvier, 1923) (see also Furtado 1999Furtado , 2001. In contrast, larvae of Psilopygida (Psigida) walkeri (Grote, 1867) use debris and their own secretions to fashion a pupation chamber (Furtado 2000).…”

“…Few studies have discussed general aspects of the morphology of the egg, larvae and pupa, and development patterns in Saturniidae (Packard 1905;Crotch 1956;Furtado 2000Furtado , 2001Fronza et al 2005). The morphology and biology of the immature stages of A. fallax are discussed and compared with other species of the genus and subfamily of these little-known moths.…”

“…isara (Dognin, 1905), A. subangulata and A. schubarti. The first of these was studied by Lampe (1987), the next two by Packard (1905: only A. subangulata) and Lemaire (1988), and the fourth by Furtado (2001). Although Balcázar-Lara & Wolfe (1997) did not include any information on the immature stages of Adeloneivaia in their cladistic study, their placement of the genus as a sister-group of the clade formed by Adelowalkeria-Citioica (sensu Balcázar-Lara & Wolfe, 1997) makes the prospect of obtaining and studying their immature stages even more attractive.…”
