Corn hybrids containing the Bt11 trait are designed to control the Asian Corn Borer
, the most damaging corn pest in ASEAN countries.
11 it is required by EU law to put an end to an approval process that began in 2001 when Dow Chemical and DuPont first submitted their product, a biotech corn variety called 1507 that has been developed to resist the European corn borer
She and her Japanese colleagues from University of Tokyo studied the two species, Asian corn borer
moth (Ostrinia furnacalis) and Japanese lichen moth (Eilema japonica).
Northrup King receives USDA approval to field test genetically-engineered corn to resist European corn borer
and dwarf maize virus.
The inch-long insect was identified as a corn borer
- a harmless caterpillar that feeds on the ears of corn and turns into a moth.
The fast food giant identified it as a corn borer
- a "harmless" caterpillar that damages the ears of corn, as well as the stalks, by chewing tunnels.
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.
MANY BIOTECH crops incorporate a bacterial gene that protects them against caterpillars such as the corn borer
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.
From corn rootworm and corn borer
protection to herbicide resistance and value-added food grade products, our new line-up of corn hybrids offers growers corn genetics paired with the right technology to thrive in this region," Becerra says.
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
