A synthesis of the mayolenes, defensive lipids from the glandular hairs of the cabbage butterfly Pieris rapae (see above), has recently been described [174].

Glycosides are elaborated by a large number of plants, and within families are often diversified in structure considerably. This diversification seems correlated with the coevolution of groups of plants with specialist herbivores. Examples are found In the Passiflora-Heliconius interaction and in the association of Pieris and Brasslca The same phenomenon has recently been determined to occur in the Drosophila-cactus-yeast coevolved system (5,6) and may be present In the Danaiid-AscIepias and other systems (7). 

Enzyme preparations of three Pieris species each contained B-thioglucosidase activity, a fact previously reported (36), and each inhibited hydrolysis in one or more combinations with a plant enzyme-substrate system. These data are being quantified and extended to include insect/preferred host-plant pairs. 

The Pieris-crucifer interaction therefore seems to involve the same biochemical parameters as the P ssiflora-Heliconius interaction, and it is proposed that the evolution of host plant specificity has proceeded in an analogous fashion in both systems.

The cabbage worm butterfly Pieris rapae crucivora and the sulfur-colored Catopsilia crocale are both found to afford the anticancer component isoxanthopterin (67) (57). In addition, isoxanthopterin (67) from the skin of the European minnow, Phoxinus phoxinus, elicits the fright reaction and hence acts as the alarm substance (52). 

Isoguanine (94), which is found in Prioneris wings along with hypoxanthine (92), xanthine (91), and uric acid (95), shows antineoplastic activities (Table VI) (57). Isolation of urocanic acid (137) from this wing material represents the first detection of this histidine derivative in an arthropod (Table VIII). A nonpteridine pigment, xanthommatin (58) (cf. Section II,B,l,b), is found in the larval body of Pieris brassicae (Table V).

Grayanotoxins.—Pieris japonica (Ericaceae) contains a number of diterpenoid toxins. An X-ray analysis of pieristoxin G (100) has been published and the structures (101)—(103) have been assigned to asebotoxins VI, VIII, and IX respectively.
