PCT No. PCT/FR95/01116 Sec. 371 Date May 13, 1997 Sec. 102(e) Date May 13, 1997 PCT Filed Aug. 24, 1995 PCT Pub. No. WO96/06171 PCT Pub. Date Feb. 29, 1996The invention relates to a sequence of nucleotides characterized in that it corresponds to the fragment HindIII of about 4.3 kb which can be obtained from the plasmid pJEG80.1 which has been deposited at the CNCM on Aug. 23, 1994 with the number I-1469 or capable of hybridizing in stringent conditions with said plasmid. It also relates to polypeptides resulting from the expression of said sequence and their utilization in toxic compositions against insects.
