On-Plant Larval Movement and Feeding Behavior of Fall Armyworm (Lepidoptera: Noctuidae) on Reproductive Corn Stages.
Spodoptera frugiperda J.E. Smith (fall armyworm) is considered one of the most destructive pests of corn throughout the Americas. Although this pest has been extensively studied, little is known about its larval movement and feeding behavior on reproductive compared to vegetative corn stages. Thus, we conducted studies with two corn stages (R1 and R3) and four corn plant zones (tassel, above ea...
متن کاملPlant-incorporated Bacillus thuringiensis resistance for control of fall armyworm and corn earworm (Lepidoptera: Noctuidae) in corn.
Fall armyworm, Spodoptera frugiperda (J.E. Smith), and corn earworm, Helicoverpa zea (Boddie), perennially cause leaf and ear damage to corn, Zea mays L., in the southeastern United States. Transgenic Bacillus thuringiensis (Bt) hybrids with the Bt11, MON810, or 176 events expressing the Cry1Ab insecticidal endotoxin from were evaluated for control fall armyworm and corn earworm at seven locati...
متن کاملBIOLOGICAL CONTROLÐMICROBIALS Enhanced Activity of the Nucleopolyhedrovirus of the Fall Armyworm (Lepidoptera: Noctuidae) on Bt-Transgenic and Nontransgenic Sweet Corn with a Fluorescent Brightener and a Feeding Stimulant
The effects of a nutrient-based feeding stimulant, Coax, and a stilbene-based optical brightener, Blankophor P167, on the activity of the nucleopolyhedrovirus of the fall armyworm, Spodoptera frugiperda (J. E. Smith) (SfMNPV) on transgenic sweet corn, Zea mays L., expressing a CryIA(b) toxin from Bacillus thuringiensis (Berliner), were studied in the laboratory. Both Coax and Blankophor P167 in...
متن کاملCan the amount of corn acreage predict fall armyworm (Lepidoptera: Noctuidae) infestation levels in nearby cotton?
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 ...
متن کاملComparison of haplotype frequencies differentiate fall armyworm (Lepidoptera: Noctuidae) corn-strain populations from Florida and Brazil.
Fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is a major economic pest throughout the Western Hemisphere. Populations can be subdivided into 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 using polymorphisms in the mitochondrial cytochrom...
