“…The number of copulations obtained in this study is within the range described for S. frugiperda by Murúa et al (2008), who found very discordant values between different populations of S. frugiperda in Argentina (0.78 to 2.32 spermatophores per female). Regarding the absence of copulation in some couples of S. eridania, these same authors reported that in some groups of S. frugiperda more than 20% of the females did not mate.…”

“…However, this variation can be attributed to several factors such as the conditions of each experiment, the biotypes related to the different host plants or different geographical regions (Giolo et al 2002;Murúa and Virla 2004;Sadek and Anderson 2007;Busato et al 2008;Murúa et al 2008). The number of eggs obtained in this study indicates that the diet and the methodology employed to rear the immature stages and the adults were suitable for the development of S. eridania in the laboratory.…”

“…However, one must consider that there are large variations between the values for the same species, especially as a function of temperature, of host plant or of an artificial diet (Parra et al 1977;Mattana & Foerster 1988;Ali & Gaylor 1992;Greenberg et al 2001;Bavaresco et al 2003Bavaresco et al , 2004Busato et al 2005;Santos et al 2005;Azidah & Sofian-Azirun 2006;Sá et al 2009;Barros et al 2010;Farahani et al 2011). Moreover, population variations should be considered, and in this sense Murúa et al (2008) indicated large variations between biological and reproductive parameters between cohorts of S. frugiperda from different locations and host plants in Argentina.…”

“…The insects used belong to the first generation obtained from 32 caterpillars collected in a soybean field crop in Jataizinho/Ibiporã municipalities, Paraná State, Brazil (23°11'11.9"S, 51°01'58.3"W, 424 m.a.s.l. ), to rule out possible mating incompatibilities, as previously described Biotic potential and reproductive parameters of Spodoptera eridania (Stoll) (Lepidoptera, Noctuidae) in the laboratory (Murúa & Virla 2004;Murúa et al 2008;Sadek & Anderson 2007).…”

“…Such differences may be attributed to the methodologies employed, the host plants, and the differences among populations, as observed for S. frugiperda (Smith, 1797) (Busato et al 2005(Busato et al , 2008Murúa et al 2008). The present work is part of a series of studies which compare different aspects of the biology of S. albula (Walker, 1857) (Montezano et al 2013), S. cosmioides (Walker, 1858), S. dolichos (Fabricius, 1794), S. eridania, and S. frugiperda under the same conditions.…”

ABSTRACT. Biotic potential and reprodutcive parameters of Spodoptera eridania (Stoll) (Lepidoptera, Noctuidae) in the laboratory: This study aimed to evaluate the biotic potential and reproductive parameters of Spodoptera eridania (Stoll, 1782) under controlled conditions (25 ± 1°C, 70 ± 10% RH and 14 hour photophase). The longevity, pre-, post-and oviposition periods, fecundity and fertility of 15 couples was evaluated. The longevity of females (10.80 days) was not significantly higher than those of males (9.27 days). The mean durations of the pre, post and oviposition periods were 2.067, 0.600 and 8.133 days, respectively. The mean fecundity per female was 1,398 eggs and the mean fertility was 1,367.50 larvae. On average, females copulated 1.133 times. A strong positive correlation was observed between the number of mating and fecundity (r = 0.881, P <0.001). However a strong negative correlation was observed between the number of copulations and the duration of the pre-oviposition period (r = -0.826, P = 0.002) and longevity (r = -0.823, P = 0.001). The biotic potential of S. eridania was estimated at 1.894 x 10 25 individuals/female/year. The net reproductive rate (Ro) was 560.531 times per generation and the mean generation time (T) was 35.807 days. The intrinsic rate of increase (rm) was 0.177, with a finite rate of increase (l) of 1.193, per week.

Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) represents a pest of economic importance in all Western Hemisphere. This polyphagous species has diverged into two populations that have been mainly recognized with various mitochondrial and nuclear molecular markers and named "the rice" and "the corn" strains. In Colombia, both strains have evolved prezygotic and postzygotic isolation. They differ in tolerance to Bacillus thuringiensis (Cry1Ac and Cry1Ab endotoxins) and the insecticides lambda-cyhalothrin and methomyl. In 2014, a wing morphometric analysis made in 159 individuals from a colony showed that both strains significantly differ in wing shape. The species also exhibits sexual dimorphism in the rice strain as in females wing size is larger than in males. Here, we continued this work with another wing morphometric approach in laboratory-reared strains to calculate wing size and shape heritabilities using a full-sib design and in wild populations to determine if this method distinguishes these strains. Our results show that male heritabilities of both traits were higher than female ones. Wild populations were significantly different in wing shape and size. These results suggest that wing morphometrics can be used as an alternative method to molecular markers to differentiate adults from laboratory-reared populations and wild populations of this pest, particularly in males of this species. Finally, Q ST values obtained for wing size and shape further demonstrated that both strains are genetically differentiated in nature.
