The average concentrations of Cr, Cd and Pb in ectoskeleton, liver, and muscle were 4.03, 0.12 and 12.31 μgg^(-1), 3.88, 1.04 and 9.12 μgg^(-1), and 4.16, 0.09 and 0.72 μgg^(-1), respectively. Among the three test sites, there existed significant differences in the enrichment of Cr in ectoskeleton and muscle, and of Cr, Cd and Pb in liver. The enrichment of test heavy metals had no notable correlation with the body mass of P. clarkia, and no significant difference was found in the enrichment of the heavy metals between female and male individuals.

When the aphids were feeding on Ww2730 seedlings, the time to 1st probing was delayed compared to those on Xiaoyan22 and Batis, searching was interrupted before 1st probing, and 1st probing was shorter than that on Xiaoyan22 and Batis significantly. Duration of pd Ⅱ-1 on Ww2730 and Xiaoyan22 was much longer than that on Batis. Duration of pd in C waveforms on Ww2730 was longer than that on Xiaoyan22 and Batis remarkedly. Times and duration of G waveform on Ww2730 were more and longer. Times of spot G waveform on Batis were more than on Ww2730 significantly, but the duration was shorter than those on Xiaoyan22 and Ww2730. Total time of E1 waveform, max longest duration of E1 fractions and mean duration time of E1 fractions following E2 wavefrom on Xiaoyan22 and Batis were all longer than on Ww2730 statistically. There were no differenences among mean durations of 1st E1 wavefrom on three varieties, but mean durations of other E1 waveforms on Ww2730 and Xiaoyan22 were shorter than those on Batis. The other waveform parameters, include times and durations of F and E2 were all not different on three wheat varieties.It is suggested that the resistance mechanism of wheat variety Ww2730 to S.
