Seeds of P. lanceolata were collected from a local population and 4 replicates of 42 maternal families were grown for 90 days in the greenhouse with at two levels of supplemental UVB radiation (6 and 12 kJ day[sup [minus]1] BE[sub 300]). Higher UVB radiation increased leaf hair density and decreased plant size during early growth; family identity affected these also. Leaves excised from a subset of the plants were fed to ultimate instar larvae of J. coenia and assayed for iridoids. Increased UVB radiation did not alter the iridoid content of the leaves or the growth of the larvae. In a separate experiment, P. lanceolata growing under the two levels of UVB irradiation were infested with neonate larvae and larval growth was monitored. Larval growth was not markedly altered by enhanced UVB. These findings suggest that increased UVB is unlikely to alter the suitability of P. lanceolata as a host for J. coenia.
