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.

European corn borer is considered to be the most important sweet corn pest in northern production areas, and second-generation borers are the principal source of ear damage.
Heavily tunneled stalks of grain corn suffer from lodging, reducing the capacity for machine harvesting. A major pest of corn, the European corn borer (Ostrinia nubilalis) will also feed on over different garden plants including peppers, snap beans, potatoes, tomatoes, apples and to corn is caused by the young larvae which chew leaves and tassels.
Later they tunnel all parts of the stalks and ears, resulting in reduced plant vigor, broken stalks, poor. The European Corn Borer [D. Caffrey] on *FREE* shipping on qualifying offers.

About European Corn Borers. Reproduction and Life Cycle. The amount of reproduction is greatly dependent on the area in which European corn borers are living. They typically have 1 to 4 generations per year based on the weather. The first 3 to 5 hours of darkness in a day is when adult European corn borer moths are most active.

Atmospheric fumigation for a period of 16 hours using methyl bromide at the following rates to be determined by the temperature of the product and interior of the car during the period of exposure.
The European corn borer has a 50° to 85°F temperature range at which it is most comfortable. Below 50°F it will not develop, and above 85°F development will slow dramatically.
Figure 1. European corn borer is a key pest of peppers and corn. The rate of development of European corn borer can be predicted using this relationship. Talk:European corn borer If you want to use the acronym ECB aka European corn borer, it should be introduced earlier, perhaps in the lead paragraph and this acronym should be used more than once.
The polyandry section is a little confusing, so I went to the actual source. From the paper, it does not actually seem like the European corn. G First Generation European Corn Borer Scouting and Treatment Decisions.
The decision to treat for European corn borer is complex and affected by many variables such as weather, plant maturity, borer survival and development, anticipated corn prices, insecticide efficacy, and costs versus anticipated returns.

Caterpillars overwintering in cornstalks and similar hiding places pupate in spring. Adult moths first appear. European corn borer (ECB) is a common pest of corn in Ohio that may cause economic losses during the growing season.
European corn borer infestations differ over time and among geographic regions in the state. Where ECB is active, the development of borers in corn stalks interferes with the flow of nutrients in the host plant, enhances infection by stalk diseases.
European Corn Borer larvae feed on several crops species including corn, cotton, and grain sorghum. Thresholds for pesticide application have been established in Missouri only for corn. Two or three generations are possible in Missouri each year. European Corn Borer. The European corn borer (Ostrinia nubilalis) was first discovered in North America in and in Manitoba in It has been an economic pest in Manitoba corn fields on a sporadic basis.
The European corn borer will feed on sweet, grain and silage corn. The European corn borer Ostrinia nubilalis (Hubner), a major pest of sweet corn, can also damage peppers, snap beans, potatoes, tomatoes, apples and other horticultural crops.
It is an introduced species which arrived in the Great Lakes area in the early 's. It is now found throughout eastern and central North America, including most parts of #: / Identifying the European Corn Borer.
The first step to knowing you have a problem with the European Corn Borer is knowing how to identify it. There are other pests that gravitate toward corn, but if you are sure of what pest you have, you can target your treatment specifically for that particular pest.
The European Corn Borer spends the winter on your old corn stalks or other. The European corn borer originated in Eurasia and was accidentally introduced into North America. This insect readily adopted corn as a host and has since caused hundreds of millions of dollars in crop losses.
This publication is an update of the version published by the North Central Region. This means that corn not protected against corn borers, including refuge corn, should be scouted now for European corn borers to determine if an insecticide needs to be applied.
Scouting Although all refuge fields should be scouted every year for European corn borer, mated females are often attracted to and lay eggs in the tallest cornfields first. Fields with chronic corn borer problems can be planted to the BT-corn borer corn varieties for control.
However, if the BT-corn varieties are planted, growers must plant a BT-free refuge according to the label requirements. The widespread planting of BT-Cornborer corn has dramatically reduced the corn borer populations across NYS.

Field Scouting and Treatment Decisions for European Corn Borer by Crop Stage In North Dakota, chemical treatments are not always warranted for controlling corn borer damage. Scout fields for determining the levels of corn borer present and use the management worksheets to assess the economic necessity of treating with an insecticide.
Development of resistance to B.t. may be delayed because untreated areas can provide a source of susceptible moths to dilute the buildup of B.t. resistant genes in the European corn borer population. The European corn borer can live on more than species of plants, so alternatives to corn as a host exist.
How Resistance Could Develop in European Corn Borers (ECB) In any population of European corn borers, a few of the borers will have two copies of genes for resistance (rr), some will have one copy of the gene (rs) and most will have none (ss).
Resistance genes are believed to be rare. The European Corn Borer and Its Control Prepared by Entomology Research Branch, Agricultural Research Service. The European corn borer 1 has become one of our most destructive pests of corn.

The SWCB has two or more generations per year. Identifying European Corn Borer’s Damage Plants Affected. European corn borer is a serious pest to more than plants. Generally speaking, they will feed on herbaceous plants with a large stem, which will provide them with a suitable entry point.
The western strain of the pest feeds primarily on corn. European corn borer overwinter as larvae in corn stalks and other residue left on the surface from the previous growing season.
As day length increases and average day temperatures exceed 10°C (50°F), the larvae pupate. Pupae are found within larval feeding tunnels and require 2 weeks to develop before adults emerge.European corn borer (Ostrinia nubilalis) has three or more yearly generations in North Carolina. Before the widespread planting of Bt corn, it was one of the most serious pests in the state.
It is now rarely encountered and only in non-Bt refuge corn. If corn is planted in a timely fashion, the first and second generation will infest the crop.European corn borer threshold using Prices Control Cost ($ per Acre) (This cost could vary greatly depending on products used, however one might also need to adjust the proportion of larvae killed if less expensive lower rates are used) Yield Loss per Borer Market Value of Corn ($/Bu) Expected Yield (Bu/A) Proportion.
