Bionomy of Anicla mahalpa Schaus, 1898 (Lepidoptera: Noctuidae: Noctuinae), in the laboratory

Abstract

415as armyworms, cutworms, semiloopers and velvetbean caterpillars (Holloway et al., 1992;Scoble, 1995 Bionomia de Anicla mahalpa Schaus, 1898 (Lepidoptera: Noctuidae: Noctuinae), em laboratório Resumo O gênero Anicla Grote, 1874 é composto por onze espécies cujas lagartas são nocivas principalmente a gramíneas nativas e cultivadas, entretanto, até o momento só existem informações a respeito de duas espécies. Este estudo objetivou detalhar a bionomia de A. mahalpa Schaus cujos dados foram obtidos a partir de uma criação laboratorial feita sob condições de 20 2 °C, 70 10% UR e 12 horas de fotofase. As lagartas foram alimentadas com azevém, Lolium multiflorum Lam. (Poaceae). Os resultados expressos pela média e pelo respectivo erro-padrão para os períodos de cada fase, em dias, foram: ovo 6,00 0,00; larva 36,47 0,44; pré-pupa 5,23 0,21; pupa 23,60 0,37 e adulta: longevidade 15,24 0,75 com períodos de pré-oviposição 5,29 0,32; oviposição 9,64 0,81 e pós-oviposição 0,71 0,27 dias. O número médio de posturas por fêmea foi 7,36 0,20 e de ovos por fêmea, 2.014,21 78,93. Os ovos, de formato subesférico, apresentam diâmetro de 0,76 0,01 mm; as lagartas passaram por seis ínstares cujas médias da largura das cápsulas cefálicas proporcionaram razão média de crescimento de 1,482. As pupas apresentaram em média largura e comprimento 6,07 0,06 e 17,24 0,19 mm, respectivamente, e peso de 0,33 0,01 g.Palavras-chave: desenvolvimento, insecta, importância agrícola, lagarta.

Life cycle of Agrotis malefida (Lepidoptera: Noctuidae): a diapausing cutworm

“…However, it differs from the results of VILLATA et al (1988), who reported an average of only 474.5 eggs per fertile female. Our results are also consistent with values obtained for other Noctuinae, such as for A. ipsilon (SWIER et al 1976-1,423.53, ARCHER et al 1980-maximum average 1,984, SANTOS & NAKANO 1982-1,263, BENTO et al 2007, Agrotis ignicans (Guenée, 1852) (FOESTER & MELLO 1996 -1,807) and Agrotis mahalpa Schaus, 1898(SPECHT et al 2008.…”

“…The high survival of A. malefida pupae (Table I) was similar to that of most noctuids reared in the laboratory, such as A. ipsilon (REESE et al 1972, BENTO et al 2007 and A. mahalpa (SPECHT et al 2008).…”

Biological aspects of Tiracola grandirena (Herrich-Schäffer, 1868) (Lepidoptera: Noctuidae): a polyphagous armyworm

“…In the latter experiment, even though nearly all the eggs were fertile to begin with, adverse laboratory conditions such as low humidity and mechanical injuries during rearing prevented larvae from hatching. The observations of our study are consistent with field observations in which eggs from females collected in nature, including the first generation, are highly viable (viability percentages above 90%) (Specht et al, 2008).…”

“…The incubation period (Table 1) of T. grandirena was slightly shorter than that observed for T. plagiata reared in the laboratory (Temperley (1930) (Specht et al (2008) ~ 6.9%), reared under similar conditions. The incubation periods of T. grandirena in this work and T. plagiata reared in the laboratory (Temperley, 1930;Catley, 1963) were much longer than in the field (3.5 to 4 days according to Catley (1963)).…”

Reproductive potential of Spodoptera eridania (Stoll) (Lepidoptera: Noctuidae) in the laboratory: effect of multiple couples and the size

“…Teston et al, 2001;Santos et al, 2005;Specht et al, 2007Specht et al, , 2008Specht et al, , 2013 may have underestimated the reproductive and/or biotic potential of the species. In nature, females attract males with pheromones and through courtship behavior (Scoble, 1995;Young, 1997), being fertilized by several males immediately after emergence.…”
