“…Due to the great variability of BIOTIC POTENTIAL, FERTILITY AND LIFE TABLE OF S. albula hosts (Montezano et al 2013), it is expected that like other representatives of the same genus (Greenberg et al 2001, Bavaresco et al 2003, Barros et al 2010, Farahani et al 2011, the net reproductive rate (Ro) of S. albula varies greatly as a function of the hosts with higher values for preferred plants, both weeds and crops (i.e. Alcaraz Vieco 1962, González-B 1966, Gloria-B 1975, Hallman 1979, Novo Padrino et al 1984, Páez Gázquez and Novo Padrino 1987, Savoie 1988, Armstrong 1994, Teixeira et al 2001, Montezano et al 2013.…”

This study aimed to evaluate the biotic potential, life table parameters and fertility of Spodoptera albula (Walker, 1857) under controlled conditions (25 ± 1°C, 70 ± 10% RH and 14 hour photo phase). The longevity, pre, post and oviposition periods, fecundity and fertility of 13 couples were evaluated. The longevity of females (13.500 days) was significantly higher than those of males (11.154 days). The mean durations of the pre, post and oviposition periods were 2.615, 1.769 and 9.385 days, respectively. The mean fecundity was 1.417.69 eggs and mean fertility was 1.340.401 larvae, per female. On average, females copulated 1, 231 times. A strong positive correlation was observed between the number of copulations and fecundity (r = 0.847, p <0.001), as well as a strong negative correlation between the number of copulations and the duration of the pre-oviposition period (r = -0.762, p = 0.002), and longevity (r = -0.788, p = 0.001). The biotic potential of S. albula was estimated at 8.768 x 10 22 individuals / female / year. The net reproductive rate (Ro) was 353,904 times per generation and the mean generation time (T) was 37.187 days. The intrinsic rate of increase (rm) was 1,105, with a finite rate of increase (λ) of 3,019.

RESUMO: O presente estudo teve como objetivo determinar a flutuação populacional e caracterizar os parâmetros faunísticos das principais espécies de lepidópteros desfolhadores que ocorrem na cultura do amendoim no estado de São Paulo. Para tanto, o levantamento populacional foi realizado em cultivo comercial de amendoim, na safra 2017/2018. A amostragem das lagartas foi realizada a cada 3-4 dias no período de 15 a 96 dias após a emergência (DAE) das plantas. O pico populacional de

RESUMONão preferência para alimentação em genótipos de tomateiro por Spodoptera frugiperda e Spodoptera eridaniaLagartas do gênero Spodoptera spp. são altamente polífagas, podendo causar danos econômicos em diversas culturas agrícolas. Em vista de sua emergente importância na cultura do tomate, principalmente o destinado à indústria, este trabalho teve por objetivo avaliar a não preferência, para alimentação, de lagartas de Spodoptera frugiperda (J. E. Smith, 1797) e Spodoptera eridania (Cramer, 1782) por genótipos de tomateiro, e classificá-los quanto aos graus de resistência. Como padrão susceptível, utilizou-se o cultivar comercial Santa Clara e, como resistente, a linhagem PI 134417, sendo avaliadas, ainda, as linhagens PI 134418, PI 126931, LA 462 e LA 716. Realizaram-se testes de não preferência, para alimentação, com e sem chance de escolha, avaliando-se a atratividade dos genótipos de tomateiro para as lagartas, em tempos pré-estabelecidos após sua liberação, além da massa foliar consumida. Em geral, os Larvae of the genus Spodoptera spp. are highly polyphagous and can cause economical losses in several agricultural crops. Given their growing importance in the tomato crop, especially for industry, this work aimed to evaluate the feeding non-preference by larvae of Spodoptera frugiperda (J. E. Smith, 1797) and Spodoptera eridania (Cramer, 1782) on tomato genotypes and classify them by the levels of resistance. The commercial cultivar Santa Clara was set as the susceptible standard and line PI 134417 as the resistant standard to evaluate the lines PI 134418, PI 126931, LA 462 and LA 716. Feeding non-preference tests were performed under non-choice and free-choice conditions to evaluate the genotype attractiveness to larvae at predetermined times after their release, as well as the leaf area consumed. Overall, the genotypes LA 716 and PI 126931 were the least attractive to S. frugiperda, whereas Santa Clara was the most attractive and consumed. For S. eridania, the genotypes PI 126931, LA 462, LA 716 and PI 134418 were the least preferred for feeding, and Santa Clara and PI 134417 were the most attractive and consumed. The genotypes LA 716 and PI 126931 are moderately resistant to S. frugiperda and S. eridania; PI 134418 and LA 462 are moderately resistant to S. eridania; PI 134417 is susceptible to S. frugiperda and S. eridania; and Santa Clara is highly susceptible to both S. frugiperda and S. eridania.
