Abstract/Contents:"Two host strains of the fall armyworm, Spodoptera frugiperda (J. E. Smith), specializing on corn (corn strain) or forage grasses and rice (rice strain), were reared on bermudagrass and corn to assess larval performance and the correlation between performance and adult fitness traits. Traits measured included larval weight and duration, pupal weight and duration, survival to adulthood, adult longevity, preoviposition period, oviposition period, fecundity, percentage of hatch, and number of progeny. None of the immature stage traits were correlated with adult traits for either strain. Specifically, pupal weight was not correlated with number of progeny produced. A quantitative genetic analysis indicated genetic control of larval but not adult traits; however, variation was not additive. The rice strain was more affected by larval host than the corn strain and performed better on its preferred host, bermudagrass, than on corn. However, larval performance on the 2 hosts is not mirrored by host specificity in nature. The rice strain is more specialized physiologically but occurs in both habitats in nature, whereas the corn strain is less specialized physiologically but rarely occupies both habitats. Thus, host-plant specialization is likely mediated by behavioral traits in adults rather than physiological ones in larvae."
