“…Similar results were obtained by Bosio et al (1990). Our results differ from those obtained by Quisenberry et al (1988), because they did not find differences in mortality caused by diets containing water extracts of different varieties of Bermudagrass, Cynodon dactylon (L.). Their results suggested that the water extractable factors did not contribute to FAW resistance in the grasses evaluated.…”

“…These have been characterized as a rice-strain that is associated with rice, pasture, and turfgrasses, and a cornstrain that predominates on corn, sorghum, and cotton. The two strains are morphologically identical, but they differ in certain physiological characteristics, including rates of development, plant host ovipositional preference, and mating preference, although there is considerable within strain variation (Pashley 1988;Quisenberry et al 1988;Whitford et al 1988Whitford et al , 1992Pashley et al 1992). …”

Fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is a major economic pest throughout the Western Hemisphere. There exist two morphologically identical but genetically distinct strains (corn-strain and rice-strain) that differ in their host plant preferences. These strains can be distinguished by polymorphisms in the mitochondrial cytochrome oxidase I gene. There is also a tandem-repeat genetic element called FR that is found in large sex-linked clusters primarily in the rice strain, as characterized by sampling of fall armyworm populations in the southeastern United States. It was recently shown that the FR element is also present in Brazil, where it exhibits a similar strain-biased distribution. In this article, the analysis of FR was extended to populations in southern Texas, one of the principle overwintering locations for fall armyworm that infests the continental United States. DNA sequence analysis and an optimized polymerase chain reaction (PCR)-based method demonstrated that FR sequences are present in Texas and show the same distribution pattern as observed in Florida. The distribution of FR in Florida has remained relatively unchanged over a 4-yr period, suggestive of polymorphic equilibrium and the existence of at least partial barriers to the generation of interstrain hybrids. The implications of these findings on our understanding of interstrain mating behavior and the utility of the modified detection method to study fall armyworm populations are discussed.

“…Specific plant cuticular lipids can contribute to resistance to insect pests by affecting insect feeding behavior, such as palpation, biting, and movement (Bernays et al, 1976(Bernays et al, , 1985Chapman, 1977;Eigenbrode et al, 1991). The addition of cuticular lipids to the diet of lepidopteran insects inhibits larval growth, and genotypic variation in these lipids may also play a role in host plant resistance (Quisenberry et al, 1988;Yang et al, 1991). In the present paper we characterize the cuticular lipids from the silks of seven corn genotypes, and we compare the growth of corn earworm larvae on these corn silks to the growth of larvae reared on silks from which the cuticular lipids have been removed.…”

Cuticular lipids were extracted from the silks of seven corn genotypes, GT201wx, GT202wx, GT210wx, GT113, GT115, Antigua 2D-118, and Pioneer X304C. These lipids were identified by combined gas chromatography-mass spectrometry. There were compositional differences between genotypes, but the major components for each extract were n-alkanes, alkenes, aldehydes, fatty acids, and fatty alcohols. Alkenes comprised a much higher percentage (between 3 % and 15 %) of the surface lipids than they do in most plant cuticular lipids. Corn earworm larvae, Helicoverpa zea, were reared on meridic diet containing either chloroform-extracted or unextracted silks from the seven genotypes. Growth of larvae was monitored and shown to be significantly greater when larvae were reared on diet containing silks from which the cuticular lipids had been removed than when they were reared on diet containing unextracted silks.
