✦ Synopsis
Pyrrolizidine alkaloids are taken up from plants by various tain compounds from plants in a complex pattern, the leaf beetle Chrysomela lapponica follows a different strategy. butterflies and moths belonging to the Danainae, Ithomiinae, and Arctiidae, which use them for defence and for the pro-Glycosidically bound alcohols present in leaves of their hostplants are liberated and transformed into esters, which are duction of male pheromones. A complex distribution scheme of these plant alkaloids by the insect has been established in used for defence. Related beetles rely on host-derived single compounds such as salicyl aldehyde or de novo synthesized some species. The transformations involved include conversion into insect alkaloids, metabolism to male pheromones, iridoid monoterpenes. Several aspects of these insect-plant relations, including biosynthetic transformations of plant and transfer of alkaloids from males to females and further into eggs. While these lepidoptera selectively sequester cer-compounds by the insects, are discussed herein.
