The flavonoids that provide insecticide-like protection to some corn lines against corn earworm larvae also provide pigments to the plants that show up in the silks, husks and kernels. Pictured here ...

Sweet corn farms in Olathe are facing a slew of bitter problems as a rise in crop pests has drastically impacted this year’s harvest. An infestation of helicoverpa zea — better known to the public as ...

Some of the most persistent pests in grain sorghum are headworms. Headworms are a class of worms that include corn earworm, fall armyworm and webworm. Webworms are more of an occasional pest and are ...

Eating a blend of non-toxic corn and genetically modified toxic corn can result in corn earworm pests (Helicoverpa zea) developing longer, more narrow and more tapered wings—shaped like the wings of a ...

Sweet corn season is here, and there's nothing like eating freshly harvested ears – unless you find a worm when peeling back the husks! That unwanted intruder is usually the corn earworm. These ...

Early corn earworm damage is evident on the leaf of a cotton plant (at left), and a sample of B. Bassiana, a parasitic fungus that attacks insects, is prepared for ...

As for insect pests, Bt (Bacillus thuringiensis) corn can help control some insect pests. Francis Reay-Jones, Clemson entomologist and Integrated Pest Management (IPM) program coordinator housed at ...

Researchers used genomics to investigate the genetic changes causing resistance to transgenic crops in field populations of the corn earworm, also known as cotton bollworm or Helicoverpa zea. They ...

Selecting an insecticide for controlling late-season insects in any crop out right now isn’t always easy or cheap. Broad spectrum insecticides, like synthetic pyrethroids or chlorpyrifos, can result ...

Researchers have developed a strategy for using genomics to monitor for and identify emerging resistance to pesticides, helping farmers prolong the effectiveness of pest management tools. Farmers rely ...

If left unchecked, insect pests can devastate crops. To minimize damage and reduce the need for insecticide sprays, crops have been genetically engineered to produce bacterial proteins that kill key ...
