摘要

Farmers, industry, scientists and environmentalists—all are fighting about how to control insect pests. That's nothing new. What is new—and ironic—is that all the groups claim to fight for the same thing: for farmers to continue, or increase, their use of one of the first major products of agricultural biotechnology, Bacillus thuringiensis, or "Bt", for environmentally safe control of insect pests. The bacterium, found naturally in the soil, produces proteins that are toxic to many insects. Farmers and gardeners have used Bt in organic insecticide sprays for 50 years.
