Area repellents are materials that are intended to keep animals away from a broad area. They include predator scent such as Hon or tiger manure, blood meal, tankage such as putrefied slaughterhouse waste, bone tar oil, rags soaked in kerosene or creosote, and human hair (84). Although few controlled tests have been mn on these materials in the past, more recent investigations of predator odors have shown promise (85).

The occurrence of pyrrolizidine derivatives in the Lepidoptera is not confined to butterflies, but has also been observed in the tiger moth, where their function may be similar to that established in one species of butterfly. Male tiger moths (fam. Arctiidae) possess scent organs in the form of inflatable coremata which have a pheromone-distributing function. Some of these species are known to use plants containing pyrrolizidine alkaloids, e.g. Heliotropium europaeum and Echium...
