We here summarize work we have done with a moth, Utetheisa ornatrix, that has a dependence on certain plant alkaloids. The moth uses the compounds for defense and for production of a pheromone that plays a decisive role in sexual selection. The species has a broad range, extending through North America east of the Rockies and southward into Brazil, Argentina, and Chile. Our studies were done mostly with populations of the moth from central Florida. [Pg.129]

Figure 12.3 Utetheisa ornatrix that were offered to the orb-weaving spider Nephila clavipes. The specimen on the right, rejected intact, was raised on one of its normal, pyrrolizidine alkaloid-containing food plants (Crotalaria mucronata). The one on the left, raised on an artificial diet devoid of alkaloid, was eaten. See also Figure 12.4. (From Eisner, 1982. American Institute of Biological Science.)...

Recent studies have provided additional details of Type II pheromone biosynthesis in two other arctiid species. For example, injection of labeled 9Z,12Z,15Z-18 COOH into pupae of female Utetheisa ornatrix resulted in incorporation of label into 3Z,6Z,9Z-21 H as expected, and also into 1,3Z,6Z,9Z-21 H (Choi etal., 2007), supporting the chain elongation... [Pg.421]
