1. A transformed potato plant comprising DNA as set forth in SEQ ID NO:
- 1 which encodes a Bacillus thuringiensis endotoxin, wherein five to ten copies of the DNA are integrated into the genome of the plant and wherein the endotoxin is expressed at a level such that the plant is resistant to Lepidopteran insects.

Abstract
Lepidopteran insect resistant transformed potato plants are described. In particular, the transformation of potato plants with five to ten copies of a translational fusion encoding the 68 kD lepidopteran-specific toxin from Bacillus thuringiensis var. kurstaki HD-73 and neomycin phosphotransferase II is described. The transgenic potato plants were resistant to the tobacco hornworm, a lepidopteran insect which is susceptible to Bacillus thuringiensis var. kurstaki toxin.
