Abstract

Neotropical Entomology 36(1): 001-004 (2007) Aspectos Biológicos de Autoplusia egena (Guenée) (Lepidoptera: Noctuidae, Plusiinae) RESUMO -Autoplusia egena (Guenée) é uma mariposa distribuída em todo continente americano. Suas lagartas alimentam-se de plantas pertencentes a diversas famílias incluindo cultivos de grande importância como soja e feijão. Objetivando contribuir para o conhecimento da sua biologia em laboratório, considerando duração e morfometria de cada fase de desenvolvimento, foi realizada uma criação laboratorial a 25 ± 1°C, 70 ± 10% UR e 14h de fotofase. As lagartas foram alimentadas com folhas de feijão-preto e os adultos com solução de mel a 10%. Os resultados expressos pela média (± EP) para os períodos de cada estágio, em dias, foram: ovo 3,0 ± 0,00; lagarta 15,7 ± 1,25; pré-pupa 1,9 ± 0,05; pupa 8,8 ± 0,09 e adulta: longevidade 12,1 ± 0,95, pré-oviposição 5,4 ± 0,50, oviposição 6,3 ± 1,10 e pós-oviposição 1,4 ± 0,87. As lagartas passaram por cinco ínstares cujos valores médios das larguras das cápsulas cefálicas, em mm foram 0,302 ± 0,001; 0,500 ± 0,003; 0,854 ± 0,008; 1,424 ± 0,011 e 2,744 ± 0,053. As pupas apresentaram comprimento, largura e peso médio de 16,965 ± 0,003 mm, 4,674 ± 0,040 mm e 0,217 ± 0,003 g, respectivamente.PALAVRAS-CHAVE: Desenvolvimento, inseto, morfometria, Phaseolus vulgaris, falsa-medideira ABSTRACT -Autoplusia egena (Guenée) is a moth distributed throughout the Western hemisphere. The larvae have already been found feeding on several different plant families, including important crops such soybeans and beans. To contribute to the knowledge of its biology in laboratory conditions, and considering the duration and the morphometry of each development stage, a laboratorial rearing was accomplished at 25 ± 1°C, 70 ± 10% RH and 14h photophase. The larvae were fed with black bean leaves and the adults were fed with a honey solution at 10%. The results, expressed by the mean (± SE), for the periods of each stage were: egg 3.0 ± 0.00 d; larva 15.7 ± 1.25 d; pre-pupa 1.9 ± 0.05 d; pupa 8.8 ± 0.09 d and adult: longevity 12.1 ± 0.95 d, pre-oviposition 5.4 ± 0.50 d, oviposition 6.3 ± 1.10 d and post-oviposition 1.4 ± 0.87 d. The larvae went through fi ve instars, for which the mean width of the cephalic capsules were 0.302 ± 0.001 mm; 0.500 ± 0.003 mm; 0.854 ± 0.008 mm; 1.424 ± 0.011 mm and 2.744 ± 0.053 mm. The average length, width, and weight of the pupae were 16.965 ± 0.003 mm, 4.674 ± 0.040 mm and 0.217 ± 0.003 g, respectively.

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.…”

Biotic Potential and Life Tables of Chrysodeixis includens (Lepidoptera: Noctuidae), Rachiplusia nu, and Trichoplusia ni on Soybean and Forage Turnip

“…Loopers (Lepidoptera, Noctuidae, Plusiinae) are an important group in this scenario because many of these species feed on a wide variety of crop species (Shorey et al 1962, Biezanko et al 1974, Boldt et al 1975, Herzog 1980, Bercellini and Malacalza 1994, Pastrana 2004, Bentancourt and Scatoni 2006, Bueno et al 2011, Moscardi et al 2012, Specht et al 2015, Santos et al 2017, Detoni et al 2018). The looper complex in soybean is composed of Argyrogramma verruca (Fabricius, 1794), Autoplusia egena (Guenée, 1852), Chrysodeixis includens (Walker, [1858]), Ctenoplusia oxygramma (Geyer, 1832), Enigmogramma admonens (Walker, [1858]), Rachiplusia nu (Guenée, 1852), and Trichoplusia ni (Hübner, [1803]) (Eichlin and Cunningham 1978, Herzog 1980, Lafontaine and Poole 1991, Specht et al 2007, Formentini et al 2015). All these species are abundant in a wide variety of agricultural ecosystems (Lafontaine and Poole 1991).…”

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

“…A. infecta ~ 1.5 - Teston et al (2001), A. mahalpa ~ 1.5 - Specht et al (2008)). The growth rate of our subjects approximated that of the noctuid Autoplusia egena (Guenée, 1852) (~ 1.7) (Specht et al, 2007), which goes through only five larval instars and was greater than that predicted for Lepidoptera [~ 1.4] (Dyar, 1890).…”
