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.

Pistillata. However, the mean growth rates of S. pistillata in two mesocosms at 25℃ were significantly different. The mean growth rates of S. hystrix in two mesocosms at 28℃ were significantly different and did not show a consistant relationship compared to those of S. pistillata. The mean growth rates of S. hystrix in two mesocosms at 20℃ were significantly different, but those of S. pistillata were the same.

在25℃的2个生态箱之间，尖枝列孔珊瑚的平均生长率相似，并且大部份都显著高於萼柱珊瑚，而萼柱珊瑚的平均生长率则显著不同；然而，在28℃的2个生态箱之间，尖枝列孔珊瑚的平均生长率变异较大，与萼柱珊瑚的平均生长率比较并无一致的趋势；在20℃的2个生态箱之间，萼柱珊瑚的平均生长率相似，尖枝列孔珊瑚却有显著不同。

The results showed that there were significant differences among parameters of texture feature of the different land utilization. In the desertification, the mean and variance were comparatively high. The gray level was asymmetry, the contrasts between neighboring pixels were significant; while in water and irrigable land, the mean, variance was a little bit low, the grey level was symmetry; the mean, variance and gray level in the forest and dry land was between the above (desertification and water and irrigable land).
