Induction of alcohol dehydrogenase null mutants in the Mediterranean fruit fly Ceratitis capitata

Alcohol dehydrogenase null mutants have been induced with X rays in Ceratitis capitata, for use in a genetic sexing system. A combination of selective medium and electrophoretic screening was used to identify these mutants. The results indicate that they are probably large deletions since no homozygotes were found for any of the induced mutants.
