性蚜

Indoor research indicates that there are remarkable differences in non-preference, antibiosis and tolerance to M. avenae, respectively, among 27 cultivars or lines of spring wheat seedlings, but no remarkable difference in the total resistance.

室内研究表明，在不选择性、抗生性和耐害性方面，27个供试小麦品种幼苗对麦长管蚜的抗性存在显著差异，但总的抗性不存在显著差异。

To probe into either the attractiveness to or avoidance from phylloxera of grape rootstocks and cultivars with different tolerance, as well as into the volatile components from their roots, the method of invitro root segment culture was used to investigate the selectivity of Phylloxera viticola Fitch to the roots of grape rootstocks '5BB' and '140Ru' and cultivar 'Kyoho'.

为了探讨不同抗性水平砧木及品种对根瘤蚜吸引及驱避效应以及鉴定挥发性物质组分，采用离体根段培养法测定葡萄根瘤蚜Phylloxera viticola Fitch对砧木5BB，140 Ru及栽培品种巨峰的选择性，发现根瘤蚜对栽培品种巨峰的根段具有很强的选择性，至接种后3d，67.13%的根瘤蚜优先选择巨峰；而对5BB和140 Ru的选择性却很差，分别有15.29%和17.58%的根瘤蚜选择5BB及140 Ru。

Electroantennogram responses to several chemical volatiles of soybean plant were investigated for the following four species of insects: 1 Aphis craccivora Koch and Macrosiphum avenae; 2 Lysiphlebus fabarum Marshall, the common nature enemy of Aphis glycines Matsumura which is the pest insect of soybean plant, and of A.craccivora which is not the pest insect of soybean plant; 3 Aphidius picipes Nees, the nature enemy of M.avenae which is not the pest insect of soybean plant.

研究了下列害虫和寄生天敌种类对大豆植株中提取的某些挥发性次生化合物及其不同组合混合相的触角电位反应： 1豆蚜Aphis craccivora Koch和麦长管蚜Macrosiphum avenae；2为害大豆植株的大豆蚜Aphis glycines Matsumura和不为害大豆植株的豆蚜二者所共有的寄生天敌豆柄瘤蚜茧蜂Lysiphlebus fabarum Marshall； 3不为害大豆植株的麦长管蚜的寄生天敌燕麦蚜茧蜂Aphidius picipes Nees。

The resistance mechanism of wheat to insects includes tolerance, nonpreference and antibiosis. The dissertation investigates the wheat mechanism, indicators and standard of resistance to aphid and analyses the relation between four kinds of second substance and the wheat resistance to aphid and research the effect of wheat varieties on carboxylesterase and glutathione-s-transferase according to the tests of three mechanism, the content of second substance and the activity of relative detoxification enzyme.

本文通过不同小麦品种的不选择性、抗生性、次生物质含量及麦长管蚜体内有关解毒酶活性的测定，进一步探讨了小麦的抗蚜机制，探索了小麦的抗蚜指标及鉴定标准；研究分析了小麦中4种重要的次生物质含量与小麦抗蚜性的关系；测定了不同小麦品种对麦长管蚜羧酸酯酶和谷胱苷肽-S-转移酶的影响。

The results sh~wed that there were significant differences between sexual forms and parthenogenetic forms of cotton aphid with characteristic bands appeared.

棉蚜性蚜人工诱导的试验结果表明：14C和 18'C下能诱导性蚜产生，而 22℃下诱导则不产生性蚜，可以估计棉蚜性蚜产生的临界温度约为 20'C左右。14℃、18℃下随光照时间的缩短棉蚜性蚜比例有提高的趋势。

If green peach aphids were grafted on the green cabbage,they developed and reproduced most rapidly.(2) If turnip aphid and green peach aphids were grafted on the tomato,they could not survive.

经黄色诱蚜，探求桃蚜和萝卜蚜的迁飞高峰规律看出，两者在一年中的迁飞高峰分别为5月中旬和11月中旬，同时曾采用多种颜色对两种蚜虫趋性的测定，其中以乳鸭黄诱得的蚜虫数最多。

Among them multi-types of body colour and special types of hosts are the most universal phenomena. In our experiment, methods of microsatellite primer PCR molecular marker and partial gene sequence analysis of mitochondrial DNA COⅠ-Ⅱwere used to analyze genetic diversity of two body colour bio-types (red bio-type and green bio-type) of green peach aphid from different plants and relationship between green peach aphid and host plants by separately selecting individuals of aphid from rape, Chinese cabbage and tobacco. The main results as follows: 1. Selecting An Ruisheng'method of extracting DNA from small sized insect, using this method can extract DNA well and steadily.

本文采用微卫星引物PCR 分子标记和线粒体COⅠ-Ⅱ部分序列分析的方法，分别选取十字花科植物中的甘蓝和油菜，茄科植物中的烟草，对不同寄主上桃蚜的红色和绿色两种体色生物型的遗传多态性及其与寄主植物的关系进行了研究，取得的主要结果如下： 1、选取安瑞生(2002)小型昆虫DNA 提取方法，能很好且比较稳定的提取桃蚜基因组DNA。

The research results offer basic indicators of resistance to aphid for identifying resistance wheat varieties and theory warranty for breeding of wheat resistance to aphid and intergrate aphid management.

研究结果为小麦品种的抗蚜性鉴定提供了初步指标，为小麦抗蚜育种和麦蚜的综合治理提供了理论依据。

The identification experiment of biotype and resistance to the aphid on the wheat of Amigo was designed on the basis of differentiation characteristic of the aphid.

根据麦二叉蚜种下生物型分化特性，设计了小麦品种 Amigo的抗蚜性和麦二叉蚜生物型鉴定试验。
