European Corn Borer and Bacillus thuringiensis
Date of this Version
Plant and Soil Sciences eLibrary (PASSeL) Lesson
This manuscript has been assigned Journal Series No. 04-09, College of Agricultural Sciences and Natural Resources, University of Nebraska.
This lesson contains information about the history, life cycle, and host plants of the European corn borer and information relating to the history and biology of Bacillus thuringiensis.
Overview and Objectives
This lesson discusses the origin and biology of European corn borer (ECB) (Ostrinia nubilalis) and Bacillus thuringiensis (Bt). ECB is a significant threat to many crops but especially to corn production. Bt has routinely been used as a spray to control insects such as ECB. Recently, genetic engineering has been employed to enable corn to produce its own resistance to ECB.
At the end of this lesson, learners should be able to:
- Describe the life cycle of the European corn borer
- List the number of ECB generations for the different regions within the United States
- Identify and describe damage caused by European corn borer
- Explain what Bt is and where it can be found
- Identify what insects are affected by Bt and how it kills European corn borer
- Identify benefits and concerns of inserting a Bt gene into corn
