15. A method of producing a transgenic plant with enhanced insecticidal properties, comprising introducing the nucleic acid molecule of claim 1 into a plant thereby producing a transgenic plant, wherein the nucleic acid molecule expresses effective insect-controlling amounts of protein.
16. A method of producing a transgenic plant with enhanced insecticidal properties, comprising the steps of:
a) providing the nucleic acid molecule of claim 1 ;
b) introducing into a plant, tissue culture, or a plant cell the nucleic acid molecule of step (a) to obtain a transformed plant, transformed tissue culture, or a transformed cell having enhanced insecticidal properties; and
c) growing said transformed plant or regenerating a transformed plant from the transformed tissue culture or transformed plant cell, so a transgenic plant with enhanced insecticidal properties is produced.

b) growing said plant under appropriate conditions to produce said transgenic seed.
18. A method of producing progeny of any generation of a fertile transgenic plant with enhanced insecticidal properties, comprising the steps of:
a) obtaining a fertile transgenic plant with enhanced insecticidal properties comprising the nucleic acid molecule of claim 1 ;
b) collecting transgenic seed from said transgenic plant;
c) planting the collected transgenic seed; and
d) growing the progeny transgenic plants from said seed, wherein said progeny has enhanced insecticidal properties relative to a non-transformed plant.
19. A method for producing a transgenic plant with enhanced insecticidal properties, comprising the steps of sexually crossing a first parent plant with a second parent plant, wherein said first or second parent plant is the plant of claim 8 , to produce a first generation progeny plant that comprises a nucleic acid sequence that is at least 98% identical to SEQ ID NO: 1 and encodes mCry3A and eCry3.1Ab insecticidal proteins, or the complement thereof.
20. A method for producing a transgenic plant with enhanced insecticidal properties, comprising the steps of:
