The results showed that the semivariogram of S.granarium was described by a spherical model,and indicated an aggregated special pattern ranging from 21 to 61cm. The semivariogram of Aphidius sp.could be also well described by spherical model, and indicated an aggregated spatial pattern ranging from 36 to 55cm.The amount and spatial distribution of Aphidius sp. w...
结果表明，不同时期麦二叉蚜种群的半变异函数曲线皆为球型，其空间格局为聚集型，变程在 2 1～6 1cm之间；蚜茧蜂种群的拟合半变异函数曲线也表现为球型，呈聚集空间格局，空间变程在 36～ 5 5cm之间，并与麦二叉蚜种群在数量和空间上有较强的追随关系，说明蚜茧蜂种群是麦二叉蚜种群的优势种天敌。

However, few studies have investigated the consequences of induced plant response due to previous insect attack on phloem-feeding insects. Herein we address whether the feeding behaviour and growth of a phloem-feeding insect are affected by host plant changes with scientific research methods using three varieties resistant wheat 98-10-30, Amigo and Batis, which are from three different countries.
本研究通过严谨的实验方法，即选定3个不同国家的小麦抗性品种98-10-30、Amigo和Batis，在所有条件严格统一的人工智能控制温室内，通过各处理在同一植株上先后不同的接蚜方式，分别测定了麦二叉蚜Schizaphis graminum和麦长管蚜Sitobion avenae Fab。

In addition this study suggested that the wheat variety 98-10-30 and Batis had the same resistance when no aphids fed on them. However, the variety 98-10-30 had better resistance for S. graminum, and the variety Batis had better resistance for S. avenae when they were fed by aphids. The variety Amigo had better resistance for S. graminum under all situations.
同时明确了3个品种对两种蚜虫的抗性状况，即在前期无蚜虫危害时，品种98-10-30和Batis对两种麦蚜的抗性相当；在前期有麦蚜危害时，品种98-10-30对麦二叉蚜的抗性较好，而品种Batis对麦长管蚜的抗性较好；品种Amigo无论在任何处理下均对麦二叉蚜的抗性较好。

The results showed that the aphids were either restrained or promoted when they fed on different treatment crops, compared with the control not fed by aphids and the corresponding treatment previously fed by different aphid species. S. avenae restrained the growth of S. graminum (MRGR=0.0974±0.0071) on 98-10-30, but S. graminum promoted the growth of S. avenae (MRGR=0.1614±0.0048) on 98-10-30. Penetrations of aphids promoted the growth of S. avenae on Amigo, while promoted growth of S. graminum on Batis.
结果表明：品种不同，蚜虫在不同处理条件下取食作物时受到的影响也不同，即在品种98-10-30上，通过与前期不接虫的对照及前期接不同麦蚜的相关处理比较，麦长管蚜对后期取食的麦二叉蚜(MRGR=0.0974±0.0071)具有抑制作用，而麦二叉蚜对后期取食的麦长管蚜(MRGR=0.1614±0.0048)却有促进作用；在品种Amigo上，前期麦蚜的危害对麦长管蚜的取食具有促进作用，而在品种Batis上前期危害对麦二叉蚜的取食具有促进作用。

Our study designed two pairs of specific primers and cloned two molecular weight of 63ku from Schizaphis graminum, and Rhopalosiphum maize utilizing PCR technique and have done the prokaryotic expression, the main results are as follows:(1)Amplified the Buchnera groEL of Schizaphis graminum, and Rhopalosiphum maize Yangling Biotype at first time all over the world ,and sequenced the full lenghth gene.
本研究设计了特异性引物，利用PCR技术从玉米蚜和麦二叉蚜中克隆出蚜虫Buchnera groEL基因并进行原核表达研究，主要结果如下：(1)从杨凌生物型玉米蚜和麦二叉蚜中在国内外首先扩增出Buchnera groEL基因，测定了全长基因序列，并对相关的同源基因核苷酸进行了比较。

The cloned Buchnera groEL genes of Schizaphis graminum and Rhopalosiphum maize were ligated into pBV221,pET30a and pTrcHisA expression vector for construction of pBVRM,pBVSG, pETRM,pETSGPR,pTrcRM and pTrcSG. They were transformated into E. coli BL21(DE3),DH5a and JM109 for studying their expression.
2将克隆的玉米蚜和麦二叉蚜Buchnera groEL基因连接到原核表达载体pBV221、pET30a和pTrcHisA上，构建了含2个目的基因的6个表达原核表达载体：pBVRM、pBVSG，pETRM、pETSG和pTrcRM、pTrcSG。
