An insect-resistant protein exhibiting a sufficient resistance to insects an insect-resistance gene encoding the insect-resistant protein a recombinant vector containing the insect-resistance gene a host cell and a plant cell having the recombinant vector transfected thereinto a transformant transformed by the insect-resistance gene and a method for producing the same a protein recovered thereby and an insect-resistant agent comprising them as active ingredients. In accordance with the present invention, the insect-resistant protein is derived from a plant.
