The effect of transgenx Bt cotton on non-target insects The kinds of the dominant species of pests in transgenic cotton field had obvious change, in which the H. armigera was no longer the main pest and the piercing-sucking pests such as Aphis gossypii, Tetranychus urticae, Thrips tabaci etc. rose the main pests. The kinds of the dominant species of predatory natural enemies seemed to be no variation, which was still Propylaea japonica Thunberg. Because of the effect of transgenic Bt cotton on H. armigera laevae-the development delay, the weight reduction, which affected the qualities of parasitic enemies, leading to the reduction of the weight of cocoon and the weight of adult, and the reduction of H.

转Bt基因棉对节肢动物群落整体结构及时序变化的影响 2001保铃棉与冀抗668的相似系数最高(0.8246)，冀抗668、保铃棉与常规防治的相似系数依次0.6459、0.5829，保铃棉和冀抗668与常规不防治的相似系数为0.5669、0.4485.2002 年与冀杭668的相似系数最高(0 。6887)，保铃棉和冀抗668与常规防治相似系数为0.4739、 0.3828，保铃棉和冀抗668与常规不防治的相似系数为0.3124、0.3999，此结果表明，两转Bt 基因棉田节肢动物群落的整体结构一致，相似性较大，与常规防治相比，相似系数有所降低，表明常规功治棉田中人为控制因素对节肢动物有一定影响；转Bt基因棉对节肢动物群落有一定影响，但并不显著。

This character is same as the viscous dampers, can thus provides constant additional damping ratio independent of the movement amplitude and unchanging the vibration frequency of structures as well.

However, the limited spatial distribution and the unpredictable occurrence of earthquakes, as well as the errors in the location of their epicenters, all these unfavorable factors heavily restrict the application of earthquakes in understanding the subsurface structure and its temporal variation in regional scale.
