The Relations of Some Native Insects to Introduced Food Plants

Coevolution of Pierid Butterflies and Their Cruciferous Foodplants. Ii. The Distribution of Eggs on Potential Foodplants

“…Butterflies first encountering T. arvense undoubtedly laid eggs on it. This response to novel potential foodplants which contain secondary compounds similar to those in normal foodplants (in this case, glucosinolates) has been extensively documented in Pieris and other Lepidoptera (e.g, Hefley, 1937;Straatman, 1962;Sevastopulo, 1964;Bowden, 1971). However, the sporadic but locally abundant distribution of this annual weed throughout its naturalized range suggests that the relative advantage accorded females which discriminate against T. arvense may not have been persistent or consistent during this period.…”
