Suppliers of beneficial organisms in North America

Biological controls that are single-celled organisms such as bacteria, fungi, protozoans, and viruses are defined as pesticides by the United States Environmental Protection Agency (U.S. EPA). In the United States of America (U.S.A.), the sale and use of these organisms are governed by U.S. EPA and state laws and regulations applicable to chemical pesticides. These organisms are widely available commercially and are not listed in this publication except in some instances in the comment sections of some suppliers.

This edition lists 142 suppliers and over 130 different species of beneficial organisms. Only commercial suppliers are listed. The suppliers are listed by country. The listing of Canadian suppliers begins on page 3, followed by Mexican suppliers beginning on page 5, and U.S.A. suppliers beginning on page 10. All the information on Mexican suppliers was obtained from Centro Nacional de Referencia de Control Biologico de la Direccion General de Sanidad Vegetal.
