Notes: Summary Aldehyde dehydrogenase (ALDH) activity is demonstrated in four strains ofD. melanogaster lacking active alcohol dehydrogenase (ADH-null mutants). In the four strains, ALDH activities are similar to those found in a wild strain. It is concluded that ADH-null flies are able to detoxify acetaldehyde. This finding is discussed in relation with the dual function of ADH proposed recently.

Description / Table of Contents: Résumé Les cristaux de deux mutants asporogènes obtenus après traitement à l'ozone ou au MNNG (N-méthyl-N′-nitro-N-nitrosoguanidine) deBacillus thuringiensis, ont démontré une toxicité accrue face à des larves deSpodoptera littoralis par rapport aux cristaux isolés à partir du type sauvage.

Notes: Abstract Crystals of two asporogenous mutants ofBacillus thuringiensis var.kurstaki strain HD-1 obtained following treatment with ozone and N-methyl-N′-nitro-N-nitrosoguanidine showed increased toxicity against larvae ofSpodoptera littoralis when compared to the wild-type crystal.
