Abstract

Recently the gene producing Bacillus thuringiensis (Bt) endotoxins has been bioengineered to facilitate Bt expression in plants. The ability to transfer foreign genes among unrelated species represents a major technological advance in modern pest management. The performance of most commercially available Bt-plants has been generally outstanding in controlling the target insect pest(s). However, because at least 16 insect species have developed some level of resistance to Bt toxins, there is concern that resistance (virulence) to Bt plants may develop. Heavy selection pressure brought about by widespread adoption of these exceptionally effective control measures is expected to encourage resistance unless scientifically sound resistance management strategies are identified and implemented.
