“…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).…”

“…for several crops of economic interest, this study compares the biology of the main representatives of Spodoptera occurring in the Americas, reared under the same conditions. This study complements previous contributions on the biology of immatures and adults of S. albula (Walker, 1857) (Montezano et al, 2013a(Montezano et al, , 2014a, S. eridania (Stoll, 1782) (Montezano, Specht, Sosa-Gómez, Roque-Specht, & Barros, 2013b, 2014b, S. dolichos (Fabricius, 1794) (Montezano et al, 2015a(Montezano et al, , 2015b and S. cosmioides (Walker, 1858) reared under the same conditions. Montezano et al (2013a) employed and validated a methodology that incorporated detailed rearing procedures not made by others studies, e.g., a larger number of neonates evaluated individually to adult emergence, including a more complete detailing of biological parameters, with minimal interference in its development.…”

“…The overall survival of immature of S. frugiperda reared on artificial diet under controlled conditions and minimal interference was approximately 93% (Table 1). The high survival observed for S. frugiperda in this study, as well as for other species reared under the same conditions: S. albula, S. eridania, S. dolichos and S. cosmioides (Montezano et al, 2013a(Montezano et al, , 2014b(Montezano et al, , 2015b, indicates the adequacy of the rearing method and the diet for comparative studies. These results can also be considered satisfactory based on a report from Singh (1983), which states that artificial diets should provide survival rates higher than 75%.…”

The fall armyworm, Spodoptera frugiperda (J. E. Smith, 1797), is the most important noctuid pest in the Americas and has recently become an invasive pest in Africa and in India. Having a detailed and standardized record of the biology and the larval development of S. frugiperda will be critical to further studies on integrated pest management, toxicology, and applied ecology. This study reports the temporal and morphological parameters of the immature stages of S. frugiperda for larvae fed on artificial diet under controlled conditions (25±1 °C, 70±10% RH and 14 hour photophase). The survival of the egg, larval, prepupal and pupal stages was 97.40, 98.33, 99.32 and 97.95%, respectively. The average duration of the egg, larval, prepupal and pupal stages were 2.69, 13.73, 1.43, and 9.24 days, respectively. All larvae passed through six instars, with significantly slower larval development for females. However, females had faster pupal development and heavier pupae, thus total time from egg to adult was not significantly different between sexes. With the growing importance of this highly polyphagous species, centralizing the fragmented information in the literature and standardizing its rearing methods will improve and facilitate future studies on this pest.

“…Thereby, according to Bernarys & Singer (2002), it can therefore also be considered polyphagous at the individual level. The number of host plants reported for S. frugiperda is higher when compared to other congeneric species of agricultural importance such as Spodoptera albula (Walker) (65), Spodoptera cosmioides (Stoll) (126), Spodoptera dolichos (Fabricius) (94) and Spodoptera eridania (Stoll) (202) (Montezano et al 2013(Montezano et al , 2014(Montezano et al , 2015Specht & Roque-Specht 2016).…”

“…Larvae need to quickly disperse (Pannuti et al 2016) in order to find food and avoid intraspecific competition and high levels of cannibalism (Bentivenha et al 2017a, b), increasing their chances of survival. Hence, the behaviour of ovipositing in large masses is related to polyphagy at the species and individual level, which is common within the Spodoptera genus (Pogue 2002;Montezano et al 2013Montezano et al , 2014Montezano et al , 2015Specht & Roque Specht 2016).…”

The fall armyworm, Spodoptera frugiperda (J.E. Smith, 1797) (Lepidoptera: Noctuidae), is the most important noctuid pest in the Americas and has recently become an invasive pest in Africa. A detailed record of S. frugiperda's host plants is essential to better understand the biology and ecology of this pest, conduct future studies, and develop Integrated Pest Management programmes. In this study, we collected and systematically arranged the fragmented bibliographic information on S. frugiperda feeding records. Furthermore, we registered new records of host plants for S. frugiperda based on eight years of surveys in Brazil. The literature review and surveys resulted in a total of 353 S. frugiperda larval host plant records belonging to 76 plant families, principally Poaceae (106), Asteraceae (31) and Fabaceae (31). The literature search revealed 274 (77 % of total) bibliographic records, while 82 (23 %) are new records from surveys in Brazil. The new comprehensive and updated host plant list will improve our understanding of pest biology and management, as well as facilitate future studies on this pest.

BACKGROUND: The invasion of Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) into the New World has made it possible for this pest to hybridize with a native American species, H. zea (Boddie), under natural conditions. We investigated the viability and development of hybrids of these two Helicoverpa species. We reared the parental species and evaluated crosses between H. armigera males and H. zea females and vice versa, two intercrosses between hybrids, and eight backcrosses between hybrids and parental species. We estimated the length of immature stages, fecundity, survival, sex ratio, and heterosis. RESULTS: Although hybridization occcurred, with heterosis during the development of immatures, reproductive incompatibilities also were observed between the parental species and between hybrids from subsequent crosses. The interspecific crosses between hybrids and backcrosses confirmed the possibility of introgression events and their perpetuation in field populations. The results indicate that hybridization events are favored at high population levels, while at low population levels the 'species identities' will be maintained. CONCLUSIONS:The possibility of interspecific gene flow and its perpetuation through successive crosses and backcrosses suggests several recommenations for management. Populations of both species should be maintained at an equilibrium level to reduce the chance of interspecific crosses, which are presumably more likely to occur during pest outbreaks. The existence of hybridization and resistance to different active pesticide ingredients should be monitored. All practices related to managing the resistance of these pests to chemical and biological insecticides should be systematized to reduce the chance of selecting for resistant individuals.
