“…Similarly, the ricestrain was more susceptible than the corn-strain to transgenic Bacillus thuringiensis Berliner (Bt) cotton (Adamczyk et al 1997). In addition, some bermudagrass cultivars bred for fall armyworm resistance showed differential effectiveness with respect to the two strains, with rice-strain larvae generally able to gain more weight and consume more plant material than their corn-strain counterparts (Jamjanya et al 1990;Leuck et al 1968;Lynch et al 1983;Pashley et al 1987a;. Clearly strain-identity must be taken into consideration when evaluating the effectiveness of new insecticides and "resistant" plant cultivars.…”

Several restriction sites in the cytochrome oxidase I gene of fall armyworm, Spodoptera frugiperda (J.E. Smith), were identified by sequence analysis as potentially being specific to one of the two host strains. Strain specificity was demonstrated for populations in Florida, Texas, Mississippi, Georgia, and North Carolina, with an AciI and SacI site specific to the rice (Oryjza spp.)-strain and a BsmI and HinfI site joining an already characterized MspI site as diagnostic of the corn (Zea mays L.)-strain. All four of these sites can be detected by digestion of a single 568-bp polymerase chain reaction-amplified fragment, but the use of two enzymes in separate digests was found to provide accurate and rapid determination of strain identity. The effectiveness of this method was demonstrated by the analysis of almost 200 adult and larval specimens from the Mississippi delta region. The results indicated that the corn-strain is likely to be the primary strain infesting cotton (Gossypium spp.) and that an unexpected outbreak of fall armyworm on the ornamental tree Paulownia tomentosa (Thunb.) Sieb. & Zucc. ex Steud. was due almost entirely to the rice-strain.

“…The two strains can be distinguished by strain-speciÞc allozyme variants and genetic markers (Pashley 1989, Lu et al 1992, 1994, Lu and Adang 1996, McMichael and Prowell 1999. Host strains differ in larval development on host plants (Pashley 1988, Pashley et al 1995, mating behaviors (Pashley and Martin 1987, Pashley et al 1992, use of food resources (Veenstra et al 1995), resistance to certain pesticides (Pashley et al 1987a), and susceptibility to different plant cultivars, including transgenic Bacillus thuringiensis Berliner plants (Pashley et al 1987b, Jamjanya et al 1990, Adamczyk et al 1997. Clearly strain-speciÞc differences have important ramiÞcations toward the development of effective control strategies, yet virtually nothing is known about the behavior of the two strains in the Þeld.…”
