Bridget F. O’Neill; Arthur R. Zangerl; Evan H. DeLucia; et al. Environmental Entomology 2008. doi:10.1603/0046-225x(2008)37[601:lafojb]2.0.co;2
Other claims from this paper (5)
- Intervention effect Japanese beetle lifespan was prolonged by 8-25% when beetles fed soybean foliage grown under elevated CO2, compared with ambient atmosphere.
- Intervention effect Soybean foliage grown under elevated O3 had no effect on Japanese beetle fecundity.
- Intervention effect Soybean foliage whose sugar content was raised by sugar solution to the level of elevated CO2 foliage had no effect on Japanese beetle fecundity or longevity.
- Intervention effect Total antioxidant content of soybean foliage did not differ significantly between ambient and elevated CO2 conditions.
- Mechanism Elevated CO2 may increase Japanese beetle populations, and their impact on crop productivity, by altering leaf chemistry other than sugar content; the precise mechanism is unclear.
