 Title    Die Verbreitung des /?-Cyan-L-alanin bei cyanogenen Lepidopteren The Distribution of /J-Cyano-L-alanine in Cyanogenic Lepidoptera  
 Abstract    The toxic amino acid /?-cyano-L-alanine is shown to be present in 21 species o f the Zygaenidae, which are known to produce and store the cyanoglucosides linam arin and lotaustralin. /?-Cyano-alanine is also reported for the first time from other cyanogenic Lepidoptera, i.e. the

 Title    A ctive Cyanogenesis — in Zygaenids and Other Lepidoptera  
 Abstract    The liberation of hydrocyanic acid by intact not damaged living insects is described as "active cyanogenesis". This phenomenon — as in contrast to "passive cyanogenesis" observed in plants, where enzyme and substrate get in contact only after tissue damage — is reported from the Zygaenidae. Quantitative data demonstrate that the Zygaenidae can increase the amount of emitted HCN upon irritation. The significance of this phenomenon as a mean of defense is discussed.

 Title    /?)MandeIonitrile and Prunasin, the Sources of Hydrogen Cyanide in All Stages of Paropsis atomaria (Coleoptera: Chysomelidae  
 Abstract    Mandelonitrile, Pruna­ sin (/?)Mandelonitrile and the cyanogenic glucoside prunasin have been established as the source of HCN in all stages of the Australian beetle Paropsis atomaria. Quantitative data for both compounds and all life stages are presented. The larvae contain a ß-glucosidase activity capable of hydrolysing prunasin and also ß-cyanoalanine synthase activity enabling the disposal of free cyanide.
