Propylaea japonica is one of important predatory natural enemies in arid and semi-arid area China, especially those preying on younger larvae and eggs of insect pest in orchards and cotton fields.

龟纹瓢虫Propylaeajaponica是我国干旱、半干旱地区农林果蔬生产中重要的捕食性天敌之一，尤其在夏季高温、干旱的情况下，对果园、棉田的幼龄害虫和卵的捕食作用非常明显。

The evaluated model of dominant predatory enemies to Aphis gossypii was constructed considering the number, temporal and spatial niche, predatory capacity of dominant predatory enemies at the same time, and based on model the control effect of Propylaea japonica was maximum, arriving at 19.82%.

综合分析了捕食性天敌优势种群的数量、与棉蚜发生在时间上同步性和空间上同域性以及捕食量大小，建立了捕食性天敌优势种群对棉蚜控制作用模型，以龟纹瓢虫控制作用指数最大，达19.82%。

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。

There were certaineffects such as Orius similis, Propylaea japonica, Misumenopos tricuspidatus.

小花蝽、龟纹瓢虫、三突花蛛等捕食性天敌也有一定控制棉铃虫幼虫的作用。

Research results indicated that the underground biomass changes of three species differed obviously under different traffic treatment. Poa pratensis and Zoysia japonica underground biomass increased at the light traffic then declined. 'Barlexas' Tall fescue decreased with increasing traffic stress. Obvious root shallowing phenomenon is displayed through the increase of roots percent in surface layer and decline in deep layer. Moreover, traffic made the soil density and hardness increase.

结果表明：践踏胁迫下，3种草坪草地下生物量变化表现出较大差异，草地早熟禾和日本结缕草先增加后下降，高羊茅一直呈下降趋势；3种草坪草表层根系（0~5cm）所占比重明显增加，深层根系所占比重减小，根系的表层化现象明显；研究还表明，践踏使表层土壤容重和硬度增加，物理性质恶化。
