Multi-state trials of Bt sweet corn varieties for control of the corn earworm (Lepidoptera: Noctuidae).
Field tests in 2010-2011 were performed in New York, Minnesota, Maryland, Ohio, and Georgia to compare Bt sweet corn lines expressing Cry1A.105 + Cry2Ab2 and Cry1Ab with their non-Bt isolines, with and without the use of foliar insecticides. The primary insect pest in all locations during the trial years was Heliocoverpa zea (Boddie), which is becoming the most serious insect pest of sweet corn...

متن کاملField-Evolved Resistance in Corn Earworm to Cry Proteins Expressed by Transgenic Sweet Corn
BACKGROUND Transgenic corn engineered with genes expressing insecticidal toxins from the bacterium Bacillus thuringiensis (Berliner) (Bt) are now a major tool in insect pest management. With its widespread use, insect resistance is a major threat to the sustainability of the Bt transgenic technology. For all Bt corn expressing Cry toxins, the high dose requirement for resistance management is n...
متن کاملSupplemental Control of Lepidopterous Pests on Bt Transgenic Sweet Corn with Biologically-Based Spray Treatments
Biologically-based spray treatments, including nucleopolyhedroviruses, neem, and spinosad, were evaluated as supplemental controls for the fall armyworm, Spodoptera frugiperda (J. E. Smith), and corn earworm, Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), on transgenic sweet corn, Zea mays (L.) (Poales: Poaceae), expressing a Cry1Ab toxin from Bacillus thuringiensis Berliner (Bacillales: Ba...
متن کاملA gene controlling biosynthesis of isoorientin, a compound in corn silks antibiotic to the corn earworm
The corn earworm (Helicoverpa zea Boddie) is an important pest of corn (Zea mays L.), and its larvae sometimes cause severe ear damage to hybrids grown in the southeastern United States. The antibiotic compound isoorientin is present in silks of some corn inbreds at a concentration that is harmful to corn earworm larvae. The inbred T218, which produces biologically active levels of this compoun...
