    Description / Table of Contents: Zusammenfassung Der Malathionmetabolismus wurde mit Hilfe der Radioisotopentechnik in normal empfindlichen und organophosphatresistenten Stubenfliegenstämmen in vivo und in vitro untersucht Die beiden malathionresistenten Stämme konnten Malathion besser in seinen Monocarboxylsäure-Abkömmling abbauen. Es wurde versucht, die hierfür verantwortliche Carboxyesterase hinsichtlich ihrer Hitzestabilität, pH-Abhängigkeit und Hemmbarkeit durch Organophosphate zu charakterisieren und ihre Bedeutung in der Resistenzbildung durch Kreuzungsresistenz- und Synergismusversuche zu bestimmen. Die Beziehung der besonders in den malathionresistenten Stämmen gefundenen malaoxonabbauenden Enzyme zu den Carboxyesterasen und ihre mögliche Identität mit denselben wird diskutiert.
    Notes: Abstract The metabolic fate of malathion in susceptible and organophosphate resistant strains of houseflies was studied by means of radioisotope-techniques, in vivo and in vitro. The main interstrain difference was the superior ability of the two malathion resistant strains to degrade malathion to its monocarboxylic acid derivative. Attempts were made to characterize the carboxyesterases responsible for this difference with respect to heat stability, pH dependency and organophosphate inhibition, and to estimate their importance in causing resistance by means of cross-resistance and synergism experiments. The relation to, and possible identity of the carboxyesterases with, the malaoxon degrading enzymes previously found in the malathion resistant strains is discussed.
