EMISSION OF VOLATILE SULPHIDE FROM RESIDUES OF DISEASED HONEYBEE LARVAE
T. A. GOCHNAUER AND V. J. MARGEITS
American foul brood scales and chalk brood mummies produced a volatile sulphide which was detected by lead acetate strips. A positive reaction required a minimum of 0·03-0·1 g larval residue per ml volume of container and an exposure time of 2-4 weeks. However, the method proved to be non-specific and is not sufficiently sensitive for detection of disease in honeybee colonies.
