Most therories of chemical coevolution between plants and                  insects assume reciprocal genetic changes effected by the                       interacting species.  Definitive genetic changes, however, have                 rarely been examined in natural systems.  In the interaction                    between Depressaria pastinacella, the parsnip webworm, and                      Pastinaca sativa, the wild parsnip, herbivory varies according to               plant furanocoumarin content and webworms can exert sufficient                  selection pressure to cause changes in the distribution of these                genetically controlled chemical traits in plant populations.  In                this project, the extent to which physiological and behavioral                  responses to parsnip furanocoumarins are under genetic control in               parsnip worms and whether these chemicals can exert sufficient                  selection pressure to change the distribution of physiological                  and behavioral traits in webworm populations will be determined.                This study will therefore provide quantitative data for                         evaluating not only concepts of chemically mediated coevolution                 but also more general theories of host adaptation and speciation                in herbivorous insects.
