Final Results of the 2001 European Corn Borer Fall Survey
This article presents the final results of the 2001 preharvest European corn borer survey. With a few exceptions, the 2001 level of European corn borers exceeded the density of this pest encountered by farmers in 2000.

Bt Corn Has Been Approved for Continued Use
On October 16, 2001, the EPA announced that it had approved the use of "corn genetically modified with Bacillus thursingiensis" (Bt corn) for another 7 years. This was good news for corn growers throughout the United States who have to contend with infestations of European and southwestern corn borers.

To ensure that Bt corn continues to be a safe and effective tool for farmers, EPA has mandated several provisions to strengthen insect resistance management, to increase research data on potential environmental effects, and to improve grower education and stewardship. This article discusses some of those provisions.

Observations on Soybean Aphids in Illinois in October
Soybean aphids leave soybeans in late summer and fall to fly to their primary host, Rhamnus species, also known as buckthorn. In 2000, after discovering the soybean aphid for the first time in North America, entomologists spent considerable effort looking for soybean aphids on Rhamnus in the fall and winter. Unfortunately, our efforts were mostly futile--very few soybean aphids were found on Rhamnus. However, the search for soybean aphids on Rhamnus this year has been more successful.

GAO Releases a Report Regarding IPM
In August 2001, the GAO released a report titled "Agricultural Pesticides: Management Improvements Needed to Further Promote Integrated Pest Management." A link to the full report is included in the article. The report is not flattering, especially to the USDA. Regardless of your reaction to these comments, you owe it to yourself to read the report.

Statistics About Agricultural Chemical Usage
This article has a link to report by the National Agricultural Statistics Service that features statistics about the use of agricultural chemicals in 2000 and previously.

Regional Reports
Extension Center educators, Unit educators, and Unit assistants in northern, west-central, east-central, and southern Illinois prepare regional reports to provide more localized insight into pest situations and crop conditions in Illinois. The reports will keep you up to date on situations in field and forage crops as they develop throughout the season.

This week's issue includes reports from northern and west-central Illinois.
