“…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.…”

“…Quando essa praga ataca plantas de até 30 dias, ela pode causar sua morte e reduzir o estande inicial e, em plantas maiores, pode comprometer a produtividade ao alimentar-se do parênquima das folhas, do broto central da planta (cartucho-do-milho) e dos grãos da espiga (Cruz & Turpin, 1983;Cruz et al, 1999).…”

“…Apesar dos avanços da pesquisa, S. frugiperda ainda é a praga que mais ataca a cultura do milho, não só no Brasil, mas em toda a América (Wiseman et al, 1966;Cruz, 1995;Cruz et al, 1999).…”

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.

“…O percentual de perdas independe do potencial de produção (Cruz et al 1999) e os prejuízos podem chegar a 500 milhões de dólares anuais . A espécie tem causado, também, sérios danos na cultura do sorgo, com perdas de cerca de 20% (Cortez & Waquil 1997), e do algodão (Gallo et al 2002).…”

“…This pest is polyphagous and is found in several countries such as Brazil, Argentina, and the USA (Prowell et al, 2004;Clark et al, 2007), causing economic losses in a variety of crops such as maize (Zea mays L.), soybean (Glycine max (L.) Merrill), cotton (Gossypium hirsutum L.), and beans (Phaseolus vulgaris L.) (Pogue, 2002;Nagoshi, 2009;Bueno et al, 2011). Because of its wide host range, S. frugiperda is one of the most harmful pests threatening annual crops in tropical regions (Andrews, 1980;Cruz et al, 1999). Control of this pest is challenging because possible host plants have different phenologies and are grown during different seasons of the year though in proximity to each other, which can facilitate movement of the pest between crops.…”

We studied Spodoptera frugiperda development using different food sources in the laboratory and field. Newly hatched larvae were fed soybean, cotton, maize, wheat, and oat leaves. An artificial diet was used as the control. Duration of pre-pupal, pupal, and larva-adult period, pupal weight, sex ratio, survival, larva feeding preferences, oviposition preferences, and nutritional quality of different hosts were evaluated. Insects fed on wheat showed the shortest larva-adult period. The insects fed on cotton and soybean had longer larval development cycles and pupae of lower weight. Feeding preference was evident for third instar larvae and did not differ between wheat, oat, maize, and soybean, which were the preferred hosts. Moths oviposited to a greater extent on the upper canopy of wheat than that of other plants in both the no-choice and free-choice tests. Treatments influenced insect growth, food consumption, and digestion when nutritional variables were analyzed. Thus, grasses were better hosts for S. frugiperda development. Cotton was the least preferred food, followed by soybean. The present study can improve our understanding of S. frugiperda in these different crops and help in developing management strategies. Even though S. frugiperda is considered to be polyphagous, this pest is closely associated with grasses (maize, wheat, oat) and has lower potential as a soybean or cotton feeder. Howerver, S. frugiperda food intake regulation appears to be triggered by a complex of different mechanisms. Thus, S. frugiperda can also damage soybean and cotton and adapt to them in the absence of preferred hosts.
