    Bt corn is a variant of maize that has been genetically altered to express one or more proteins from the bacterium Bacillus thuringiensis including Delta protein is poisonous to certain insect pests. Spores of the bacillus are widely used in organic gardening, although GM corn is not considered organic. The European corn borer causes about a billion dollars in damage to corn. Insects and fungi from Europe became serious pests in the United States, too. Among these were the European corn borer, the gypsy moth, and the chestnut blight, which practically annihilated that tree. The first book to deal with pests in a scientific way was John Curtis’s Farm Insects, published in Though farmers were well aware that.

    Southern cornstalk borer (Diatraea crambidoides) and the stalk borer (Papaipema nebris) were once frequently found in fields across North Carolina. However, due to the widespread planting of hybrids expressing Bt toxins, they are rarely encountered and only in non-Bt refuge corn. Infestation of these insects in whorl stage corn is usually greatest under certain. in , European corn borer, Ostrinia nubilalis (Hübner), now has spread as far west as the Rocky Mountains in both Canada and the United States, and south to the Gulf Coast states. European corn borer is thought to have originated in Europe, where it is widespread. It also occurs in northern Africa. The North American European corn borer popula-.

These parasites kill the borer in May and form their white cocoons. In this stage the species is very sensitive to nioisturo. All emerging adults are females, and. the European corn borer {Pyrausta nubilcdis Hbn.) in France early in the investigations initiated by the Bureau of Entomology to study the parasite complex of this insect pest in its native home, and subse- quent extensive held observations (J, iY have shown it to be fairly generally distributed throughout Europe.

Thompson and Parker {6, p. To furnish parasites for release inoverwintering corn borer larvae were collected in two localities, central Connecticut and southeastern Massachusetts, in the fall of Several of the most important parasites of the European corn borer imported from Europe and the Orient are established and abundant in these localities.

Collections were made in central Connecticut during the period Author: Charles A. Clark, Stanley W. Carter. Current Status of European Corn Borers Reports during the first full week of July and the early part of the second week confirmed our assessment of European corn borer infestations in Illinois.

In some areas of the state, infestations were quite heavy; and, in other areas, corn borer activity was minimal. Corn Borers European and southwestern corn borers occur statewide and are generally present from light to heavy numbers except in early planted corn.

The southwestern corn borer is the more destructive of the two pests due to greater lodging. The European corn borer overwinters in any part of the corn plant – stubble, stalks or cobs.

The larva. The European corn borer (Ostrinia nubilalis), also known as the European corn worm or European high-flyer, is a moth of the family Crambidae which includes other grass moths.

It is a pest of grain, particularly corn (maize or Zea mays).The insect is native to Europe, originally infesting varieties of millet, including broom European corn borer was first reported in North America in. There are three major insect pests of sweet corn in New England: European corn borer, corn earworm and fall armyworm.

All spend their adult life as moths, but the damaging stage of the insects are the larvae or caterpillars, commonly referred to as “worms,” which feed on the leaves, stalks and ears of the corn.

European Corn Borers are a voracious pest of corn, potatoes and many other commercial crops causing large-scale yield loss. Control of the damaging larval stage is imperative, but egg and adult moth control should not be overlooked.

Following Integrated Pest Management practices will allow you to control multiple life stages of the European Corn Borer without the use of heavily toxic chemical.

The results of the modeling effort will contribute to Objectives 2 and 3. Results will also likely influence U.S. EPA regulation of transgenic insecticidal corn and decisions by the seed industry concerning resistance management.

European Corn Borer Introduction The European corn borer (ECB, family Pyralidae, order Lepidoptera) arrived in North America dur-ing the early s, probably in broom corn imported from Hungary and Italy for the manufacture of brooms.

First noticed near Boston inECB has since become one of the most destructive pests of corn throughout. Although relatively few attempts have been made to control native and imported pests with parasites and predators of species allied to the pest species, the proportion of successes is surprisingly high.

This invasive pest is present in limited distribution in the United States. Some states may wish to seek federal recognition of a state-managed program to justify action at ports of entry.

The Formosan termite is not a candidate for the FRSMP program. Field corn (grain and silage), popcorn and seed corn. Apply in a minimum of 2 - 5 gallons of spray per acre by aircraft or 10 gallons per acre with ground equipment. Do not apply within 30 days of harvest.
