Aspects of the biology and biological control of the European corn borer
in North Carolina.
steady decline in European corn borer
populations over the last decade
To understand the mating behavior of the European corn borer
, first, the researchers followed the flights of males to female pheromones in a wind tunnel.
Phenology and distribution level of the European corn borer
, Ostrinia nubilalis (Huebn.) (Lepidoptera: Pyralidae) in southern Manitoba.
However, the amount of feeding done by the cabbage looper and cabbageworm, cankerworms, corn earworms and the European Corn borer
, cutworms and the granddaddy of caterpillars, the tomato hornworm, which can grow up to 5 inches long, is extensive.
* Northrup King receives USDA approval to field test genetically-engineered corn to resist European corn borer
and dwarf maize virus.
Kauralexins and zealexins, members of a larger family of plant-defense compounds known as "terpenoid phytoalexins," are also partly triggered by insect chewing--with Ostrinia nubilalis, the European corn borer
, among species that find them distasteful.
This contains the gene of a bacterium producing Bt toxins, which destroy the larvae of a parasitic butterfly (the so-called caterpillar of the European corn borer
), infestation with which constitutes a danger for the development of the maize plant.
They said Midwestern states that planted corn genetically modified to make a toxin that fights off European corn borer
moths has dramatically cut the $1 billion in annual losses from the pest, even preserving crops that have not been altered.
Zhu and his collaborators also have investigated gene silencing in the European corn borer
and in grasshoppers, a major insect pest in China.
Furthermore, conventional corn has lower yields than Bt corn because it is more susceptible to the European corn borer
