Publication on Alternatives to Pesticides for Insect Control

Alternatives in Insect Management: Biological and Biorational Approaches, NCR 401, by Rick Weinzierl and Tess Henn, is a well-written 73 page extension bulletin that provides background information and evaluations of the safety and effectiveness of several alternative products and practices that are available for use in insect pest management. The publication is divided into four chapters on microbial insecticides, botanical insecticides and insecticidal soaps, insect attractants and traps, and beneficial insects and mites. An extensive table in Chapter 3 presents suggested guidelines for specific uses of attractants and traps. The basic principles of biological control are briefly presented, and a wide variety of commercially available and naturally occurring natural enemies are discussed. Line drawings accompany the descriptions of common natural enemies. Another large table in Chapter 4 provides information on the use of beneficials against pests on a variety of crops, adapted from scientific literature and supplier's recommendations.

This publication is available through most North Central states extension bulletin offices. If they do not have copies, contact
