Larvae of C. scripta grown on 2X-treated leaves had a significantly reduced consumption efficiency compared with larvae on 1X-treated leaves in the field study.

e1“Ramets of Populus trichocarpa Torr. & Gray (black cottonwood) were subjected to near zero (0X), ambient (1X) or twice ambient (2X) doses of biologically effective UV-B radiation (UV-B(BE))”
e4“In feeding preference trials, adult C. scripta chose 2X-treated tissue almost twice as often as 1X-treated tissue in both greenhouse and field studies, but differences were not statistically significant (P = 0.12)”
e5“In the field study, first instar larvae grown to adult eclosion on 2X-treated leaves had a significant (P < 0.001) reduction in consumption efficiency compared with larvae grown on 1X-treated leaves”

Other claims from this paper (7)
- Intervention effect Enhanced UV-B increased foliar nitrogen and chlorophyll concentrations in young leaves in the greenhouse study.
- Intervention effect Enhanced UV-B slightly decreased tannins in young leaves in the greenhouse study.
- Intervention effect Enhanced UV-B increased methanol-extractable foliar phenolics in both greenhouse and field studies.
- Intervention effect Adult C. scripta chose 2X-treated tissue almost twice as often as 1X-treated tissue in feeding preference trials; the difference was not significant.
- Intervention effect Enhanced UV-B had minimal effects on photosynthesis.
- Intervention effect Enhanced UV-B had minimal effects on growth, leaf area and biomass distribution.
- Intervention effect In the field study, enhanced UV-B had no significant effect on these leaf parameters (foliar nitrogen, chlorophylls and tannins).
