寄主植物

Haustoria A specialized outgrowth of many parasitic fungi and certain parasitic plants such as dodder and broomrape, that penetrates into and withdraws food material from the cells of the host plant.

吸器：是某些寄生真菌和某些寄生植物如菟丝子和肉苁蓉所长出的特化结构，它可以刺入寄主植物体内并从寄主细胞中吸取营养物质。

"Dodder is a very difficult pest to control," De Moraes says."The reason for that is that it attaches to the host plant, and it makes it very hard to kill the weed plant without killing the host."

"菟丝子是非常难以控制的有害植物，"德·莫拉埃斯说，"由于它缠绕在寄主植物上，若不杀死寄主植物，也就很难消灭它。"

Glabripennis. The research of ability of arresting of host trees and moulds to A. glabripennis showed that there was a recognition process involving feeling, gustation and olfaction after the beetle landed on host trees or models, then the beetle made its choice to accept or reject host trees after comprehensive recognition.

寄主树种和模具对光肩星天牛的滞留效应研究表明：在对寄主植物做出定向后，天牛对寄主有一个识别过程，此过程涉及到触觉、味觉和嗅觉等，经各种感觉机制的综合作用，对寄主植物做出取舍决定。

A series of interactions such as nematode pathogenicity, host susceptibility and host resistance could form due to parasitism.

寄生过程引起的根结线虫与寄主植物之间的一系列互作反应，包括根结线虫对寄主植物的致病现象，寄主植物的感病反应和抗病反应。

Assulta and the induction of GST activity by nicotine and capsicine in H. assulta provided partial supports for the hypothesis that diet breadth was governed by detoxification abilities. The results also indicated that two sibling species had different strategies of adaptation to toxic substances: H. assulta saves expenditure of nutrients and energy by restricting their countermeasures to a few potentially toxic compounds. H. armigera, by contrast, must be prepared to counter a wider range of potential toxins. 5. Compared with parental species, hybrids of reciprocal hybridization had significant difference in feeding preference for hot pepper.

结果显示，广食性的棉铃虫在中肠羧酸酯酶和谷胱甘肽-S-转移酶活性方面高于寡食性的烟青虫，但烟青虫谷胱甘肽-S-转移酶活性可以被寄主植物内的烟碱和辣椒素所诱导，表明解毒酶活性在一定程度上影响着植食性昆虫的食性广度；同时也暗示着二近缘种对有毒的次生物质采取不同的适应策略：烟青虫有选择地对付种类较少的植物次生物质以减轻营养和能量的消耗；棉铃虫则必须对付存在于其寄主植物内的种类繁多的有毒次生物质。

The main results are as follows: l.The olfactory response of Tetranychus viennensis to different plants odors: Olfaction takes part in the response during the hawthorn spider mite looking for host plants, that means Tetranychus viennensis were attracted by odors from host plants.

结果如下：1。山楂叶螨的雌成螨对不同植物叶片挥发性物质的嗅觉反应：山楂叶螨在寻找寄主植物的过程中，嗅觉参与反应，即山楂叶螨能被寄主植物释放的气味物质所吸引；不同的寄主植物对山楂叶螨的引诱程度不同，苹果、梨等的引诱作用较强(着螨率95％，77.5％)，日本樱花的引诱作用较弱(着螨率45％)。

Mainly belonged to Loranthaceae. Plants of Phacellaria Benth. and their hosts were mainly distributed in tropical and subtropical area. Plants of Phacellaria Benth. maybe originated in tropical area in the south of China before Tertiary. Their ancestors were parasitic on ancestors of some plants of Loranthaceae by chance during Tertiary. It took them millions of years to form a sturdy relationship between parasites and hosts. Ph. rigidula was a hemi-parasitic subshrub. In area observed, its host was mainly Taxillus caloreas var. fargesii.

的硬序重寄生(Ph.rigidula)及其寄主植物做为研究植物与植物间协同进化的材料，对重寄生属植物的起源、与其寄主的分布、硬序重寄生的形态学特性、解剖学以及化学成分进行了研究，结果表明：重寄生属植物主要寄生在桑寄生科植物上，分布区与其寄主的基本一致，均主要分布在东南亚和中国南部的热带与亚热带地区；重寄生属植物可能起源于第三纪之前某一时期的华南热带地区，随后向周边地区扩散。

Furthermore, there is a great phenotypic diversity among the new strains isolated from the same host. Different groups consisted of the new strains from the same host, some were Rhizobium, some were Bradyrhizobium, such as the new strains isolated from leguminous plants of AMkora Prain, Trifolium repens Lam, Aeachynomene Mica L, Indigofera bungeana Steud.

同时，攀西地区豆科植物根瘤菌的多样性还表现在某些来自同一种寄主植物根瘤菌的多样性方面，如分离自山槐、白车轴草、合萌、铁扫帚上的同一种寄主植物内的根瘤菌分别聚在不同的表观群；且来自山槐、合萌、铁扫帚上的根瘤菌既有快生型，又有慢生型。

Cinnabarinus.The life table of experimental population of T. urticae Koch was established at constant temperature of 25 C, illumination time of 16 hours one day and humidity of 50%.The result of the experiment indicated that the value of the innate capacity of increase was 0.2634, 0.1788, 0.2098, 0.2280, 0.1538 on kidney bean, cotton, apple, aubergine and capsicum respectively and the quantity of the offspring obviously increased. When the age distribution of experimental population was steady, the amounts of the immature age were 88.3335%, 85.3052%, 85.0386%, 87.3787% and 86.8404% on five host plants respectively and the amounts of the adults 11.6636%, 14.6946%, 15.0635, 12.6218% and 13.1598% correspondingly.

通过对二斑叶螨在5种寄主植物(四季豆Phaseolus vulgaris、棉花Gossypium hirsutum、苹果Malus pumila、茄子Solanum melongena、辣椒Capsicum annuum)上的实验种群生命表的组建分析，计算出其在这5种寄主植物上内禀增长力r_m分别为0.2634、0.1788、0.2098、0.2280、0.1538；次代种群数量显著增长，在不同寄主植物上每雌产雌数存在极显著差异；在稳定种群年龄分布中，未成熟期在5种植物上分别占总量的88.3335％、85.3052％、85.0386％、87.3787％和86.8404％，成螨期分别占总量的11.6636％、14.6946％、15.0635％、12.6218％和13.1598％；对致死率为99％的不良环境的反应时间都小于30d。

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.
