“…Portanto, o rendimento na produtividade para o híbrido triplo BRS 3123 foi comprometido em 54,49%. Esse resultado foi maior do que os obtidos por Cruz et al (1999, Cruz & Turpin (1983) e Marenco et al (1992), que relataram perdas ao redor de 20% devido ao ataque da praga. Nesses trabalhos, a praga estava sujeita à livre-ação de seus inimigos naturais.…”

Resumo -Este trabalho teve como objetivo quantificar as perdas na cultura do milho BRS 3123 decorrentes do ataque da lagarta-do-cartucho (Spodoptera frugiperda), na ausência e presença de seus inimigos naturais. Aos 15 dias depois da emergência da planta, foi realizada uma infestação artificial da praga (uma postura por metro quadrado). As lagartas alimentaram-se da planta, sem a interferência de seus inimigos naturais, pela utilização de uma gaiola de proteção (inicial, de dois dias depois da infestação, até uma proteção máxima de 16 dias). O dano da praga, determinado por uma escala de notas de 0 (plantas sem dano) a 5 (plantas mortas), foi em média de 4,01, 1,39, 1,09 e 0,93 para o período de proteção da praga de 16, 6, 4 e 2 dias, respectivamente. Na ausência de agentes de controle biológico, o ataque da praga ocasionou perdas na produção de matéria seca de 47,27% e perdas no rendimento de grãos de 54,49%. Os resultados evidenciaram a importância dos inimigos naturais na supressão de lagartas de S. frugiperda na cultura de milho.Termos para indexação: Spodoptera frugiperda, inimigos naturais, silagem, produtividade de milho. Relationship between fall armyworm and their natural biological control agents in the maize cropAbstract -This work had the objective of quantifying the losses in the maize hybrid BRS 3123 due to the attack of fall armyworm (Spodoptera frugiperda), in the absence or presence of its natural enemies. Fifteen days after the plant emergency, an artificial infestation (one egg mass per square meter) was accomplished. The larvae fed on the plant, without the interference of its natural enemies, by using an appropriated protection cage (initial protection for two days after infestation, until a maximum protection period of 16 days). The damage caused by the pest, determined through a visual scale from 0 (plants without damage) to 5 (dead plants), was on average, 4.01, 1.39, 1.09 and 0.93 for the pest protection period of 16, 6, 4 and 2 days, respectively. In the absence of the biological control agents, the attack of the pest caused losses of 47.27% in the dry matter production and losses of 54.49% in grain yield. The results evidenced the importance of natural enemies in the suppression of fall armyworm in maize crop.

Background: Annonaceous acetogenins enclose a large number of biological activities, among which the insecticidal stands out. Methods: We report herein the biocide effects of natural acetogenins from Annona squamosa, A. muricata and A. montana seeds: annonacin, cis-annonacin, cis-annonacin-10-one, asimicin, rolliniastatin-2, cherimolin-1, cherimolin-2, almuñequin, and two β-OH acetogenins: laherradurin and itrabin on Spodoptera frugiperda Smith (Lepidoptera: Noctuidae). Also, some acetylated and methoxy methylated ACG derivatives were synthesized and evaluated: annonacin (3 OAc), annonacin (4 OAc), asimicin (3 OAc), rolliniastatin-2 (3 OAc), rolliniastatin-2 (MOM), laherradurin (3 OAc) and itrabin (3 OAc). Results: The natural acetogenin rolliniastatin-2 (100 μg•g −1 of diet) produced the most important toxic action causing 100% mortality of early instar larvae. Derivatization of ACG yielded compounds that produced nutritional alterations. The incorporation of rolliniastatin-2 (3 OAc) and rolliniastatin-2 (3 MOM) (100 μg•ginto the artificial diet of Spodoptera frugiperda displayed the strongest antifeedant effects causing marked decreasings in larval growth and adult lethal malformations. Conclusion: Natural acetogenins are promising metabolites for insect control. Derivatization of these compounds reduces their toxicity to early instar larvae.

“…Diego M. Viteri 1, *, Angela M. Linares 2 , Irma Cabrera 3 , and Leidy Sarmiento 1 Corn earworm, Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), and fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), are important pests of sweet corn, Zea mays L. (Poaceae), in the tropics and elsewhere (Belay et al 2012;Bohnenblust et al 2013). Larvae of both species feed on different plant parts (e.g., leaves, tassels, and ears) during the entire growing season, causing yield losses of over 20% (Marenco et al 1992;Bohnenblust et al 2013;Aguirre et al 2016). The use of insecticides is the most effective strategy to control larvae of corn earworm and fall armyworm.…”
