    A local isolate of Bacillus thuringiensis,designated L1-2, that is toxic to Chilo partellus was found to be toxic to the adult tsetse fly, Glossina morsitans morsitans. The delta-endotoxin crystals derived from the isolate gave a major protein band with a molecular weight of Mr 130,000-140,000 on denaturing polyacrylamide gel electrophoresis. The sequence of the cloned gene was found to be similar to that of the B. thuringiensis subsp. kurstaki HD-73 cryIA(c) gene, having one amino acid difference at position 148 and four additional DNA differences.
