Can the Amount of Corn Acreage Predict Fall Armyworm (Lepidoptera: Noctuidae) Infestation Levels in Nearby Cotton?

Abstract: Fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is a major pest of corn, Zea mays L., and a significant, but more sporadic, pest of cotton, Gossypium hirsutum L., in the Western Hemisphere. Previous studies showed that the cotton infestations primarily involve a fall armyworm subpopulation known as the "corn-strain" for which corn is the preferred host plant. It was suggested that the fall armyworm infesting cotton originated in corn and spread into secondary hosts as their numbers … Show more

“…They are commonly referred as the rice-strain (R-strain) and the cornstrain (C-strain) (Quisenberry, 1991;Nagoshi and Meagher, 2004). 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).…”

“…Spodoptera frugiperda Smith (Lepidoptera: Noctuidae) is a polyphagous and voracious pest that cause damage to several crops such as corn, cotton and soybean (NAGOSHI, 2009;BUENO et al, 2011). Currently, the most common control measure to manage S. frugiperda is insecticides (van LENTEREN & BUENO, 2003).…”

“…O plantio em áreas próximas de diferentes culturas com fenologias distintas, como é o caso da soja, do milho e do algodão que são cultivados no verão, além de plantas de cobertura na entressafra, como o milheto, pode favorecer o movimento de S. frugiperda entre os cultivos (Nagoshi 2009). Esse fato pode ser a causa da ocorrência mais frequente da praga em culturas onde anteriormente era considerada praga esporádica ou secundária.…”
