Other claims from this paper (4)

Intervention effect Parasitized gypsy moth larvae fed tree foliage on all diets grew more slowly than control larvae.
Intervention effect Parasitized gypsy moth larvae had reduced food processing efficiencies relative to control larvae.
Intervention effect The magnitude of growth suppression of parasitized gypsy moth larvae was greater under elevated CO2 than under ambient CO2.
Association Parasitoid (Cotesia melanoscelus) performance varied in relation to host plant species.

Other claims from this paper (12)

Intervention effect Elevated CO2 reduced foliar nitrogen levels.
Intervention effect Elevated CO2 increased foliar carbon-based compounds including starch and phenolics.
Association Changes in foliage chemistry under CO2 altered gypsy moth growth and development slightly and variably across tree species.
Association Gypsy moth larvae feeding on high CO2 aspen had the largest performance reduction relative to larvae on birch, oak, or maple.
Association Parasitism by C. melanoscela prolonged gypsy moth development significantly.
Association Parasitism by C. melanoscela reduced gypsy moth growth rates.
Association The parasitism effect on gypsy moth performance did not differ between CO2 treatments.
Association Altered moth performance on high CO2 foliage affected parasitoid performance variably.
Association Parasitoid mortality increased under high CO2.
Association Adult female parasitoid size declined slightly under high CO2.
Association Adult male parasitoid size was unaffected under high CO2.
Observation The authors interpret third-trophic-level effects of CO2-driven chemistry changes as weak to nonexistent.
