Pyrrolizidine alkaloids in arctiid moths (Lep.) with a discussion on host plant relationships and the role of these secondary plant substances in the Arctiidae
Pyrrolizidine alkaloids (PA) have been identified in six species of Arctiidae reared on Senecio and Crotalaria. These include senecionine, seneciphylline, integerrimine, jacobine, jacozine, jacoline,… Expand

The biological roles of pyrazines: evidence for a warning odour function
Recently it has been shown that pyrazines are associated with many aposematic, chemically defended insects. We have demonstrated that naive hatchling chicks, when offered drinking water to which… Expand
Cannabis sativa: volatile compounds from pollen and entire male and female plants of two variants, Northern Lights and Hawaian Indica
Sixty-eight compounds were identified by coupled gas chromatography and mass spectrometry (GC-MS) in the chemosphere of Cannabis sativa L. pollen and entire male and female plants of two cultivated… Expand
Callimorphine: identification and synthesis of the cinnabar moth “metabolite”.
Abstract Callimorphine, a putative pyrrolizidine alkaloid metabolite found in some Arctiid moths which feed as larvae on plants containing pyrrolizidine alkaloids, has been identified and synthesised.

Abstract. 1. Animals and plants may gain protection by reminding would‐be aggressors of failure, or an unpleasant experience following an attempt at capture and ingestion. Thus they need not be… Expand
Carotenoids of butterfly models and their mimics (Lep: Papilionidae and Nymphalidae)
Carotenoid concentration in model swallowtail butterflies is exceptionally high; it is suggested that they may exert a photo-protective function in species storing nitrophenanthrenes. Carotenoid… Expand
