Corn Insects & Pests:

Bt Corn & European Corn Borer: Long-Term Success Through Resistance Management. Maintained by Extension Service, University of Minnesota, USA. The document was coordinated by Information Development for Extension Audiences (IDEA). This document covers Bt corn topics and problems. You will find information from "What is Bt?" over "Are other insect pests or mites controlled by Bt corn?" to "Can resistance development be monitored?". Where appropraite figures are included as text links and a glossary is also available. This document is very informativ especially for those not familiar with Bt corn and it is kept short, so that you will easily found the information you are looking for. I would recommend this website to those who want to get very well-founded extension information.

An insecticide and a bibliography section as well as links to the company are also available. The provided information and the organization of this easy to use guide makes it a tip for this section.
