Abstract

Fertilidade e longevidade de Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) em genótipos de milho.Ciência Rural, v. 34, n. 2, mar-abr, 2004. Ciência Rural, Santa Maria, v.34, n.2, p.345-350, mar-abr, 2004 ISSN Fertilidade e longevidade de Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) em genótipos de milho (4,78; 3,94; 3,94 dias); oviposição (7,55; 6,5; 6,11 dias) e pós-reprodutivo (4,87; 4,64; 5,5 dias); número de posturas/fêmea (6,33; 5,25; 4,88) e de ovos/postura (216,72; 215,03; 226,02); viabilidade dos ovos (59,02; 69,76; 60,81%); intervalo entre oviposições (0,63; 0,86; 1,0 dias); longevidade dos machos (15,22; 13,62; 13,29 dias) e fêmeas (16,33; 14,06; 15,65 dias) com prole; e dos machos (19,17; 13,67; 13,86 dias) e fêmeas (16,43; 8,25; 19,37 400 and BR PAMPA, respectively, were not noticed, 3.94; 3.94 days); oviposition (7.55; 6.5; 6.11 days) and postreproductive (4.87; 4.64; 5.5 days) periods; number of ovipositions/female (6.33; 5.25; 4.88) and eggs/ oviposition (216.72; 215.03; 226.02); eggs viability (59.02; 69.76; 60.81%); interval between ovipositions (0.63; 0.86; 1.0 days); longevity of male (15.22; 13.62; 13.29 days) and female (16.33; 14.06; 15.65 days) with offspring and of the male (19.17; 13.67; 13.86 days) and female (16.43; 8.25; 19.37 days) without offspring. The incubation period of the eggs generated by females whose caterpillars were kept in BR 400 genotype was numerically longer than the others.

Developmental Parameters of Spodoptera frugiperda (Lepidoptera: Noctuidae) Immature Stages Under Controlled and Standardized Conditions

“…The relatively high egg viability (Table 1) is consistent with studies reported in the literature for S. frugiperda (e.g., Luginbill, 1928;Leiderman & Sauer, 1953;Busato et al, 2008;Milano, Berti Filho, Parra, & Cônsoli, 2008) and other species from the same genus (e.g., Sadek & Anderson, 2007;Montezano et al, 2013aMontezano et al, , 2014bMontezano et al, , 2015b. The egg incubation period of S. frugiperda ranged from two to three days (Table 1) and was similar to other reports for S. frugiperda reared under similar temperatures and conditions (e.g., Hynes, 1942;Veloso, Parra, & Nakano, 1983;Nieto-Hernández & Llanderal-Cázares, 1982;Machado, Giannotti, & Oliveira, 1985;Clavijo, Fernández, Ramírez, Delgado, & Lathullerie, 1991;Rizzo & La Rossa, 1992;Valverde, Toledo, & Popich, 1995;Santos, Redaelli, Diefenbach, & Efrom, 2004;Busato et al, 2005). This study also shows that the egg incubation period for S. frugiperda is shorter than the one observed for S. albula, S. cosmioides, S. dolichos and S. eridania reared under the same conditions (Montezano et al, 2013a(Montezano et al, , 2014b(Montezano et al, , 2015b).…”

Toxicidad sobre Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) de la proteína Bt expresada en hojas de diferentes eventos de maíz transgénico iberados en Paraguay

“…En cada columna, diferentes letras denotan diferencias significativas detectadas por el Test de Tukey P < 0,05. posible antibiosis por efecto de la toxina Bt. Alimentando larvas de S. frugiperda con diferentes genotipos de maíz convencional, Machado et al (2004) obtuvieron una duración de 3,94 ± 0,584 días en la pre-oviposición; una oviposición de 6,11 ± 0,469 días y post-oviposición de 5,50 ± 1,348 días; datos superiores a los obtenidos en esta investigación.…”
