| Abstract: | A series of experiments using open-top fumigation chambers was carried out to investi gate the effect of SO2-polluted rape on performance of the turnip aphid, Lipaphis erysimi(Kaltenbach).Proper SO2 concentrations significantly enhances growth and reproduction of the aphid. Nymph MRGR and adult fecundity reached their maxima at 116 nl/L and 80 nl/L of the pollutant, respectively. Potential of the population growth got fully displayed at the latter dose because the highest survival rate of the nymphs also took place at this concentration.It is suggested according to changes in the plant chemistry that this indirect effect of SO2 pollution on the turnip aphid might involve variation in content of individual key free amino acid rather than total amount of all the amino acids in the leaves induced by the air pollutant. |
