The exact position where pear scab parasite in leaves was pectin layer.The primary injections of V.nashicola to resistant,suspectible and non-host materials were similar,the increasing rate of subcuticular hyphae on suspectible material is far higher than resistant and non-host material,and dead hyphae appeared on resistant and non-host material,which indicated that resistance expressed after hyphae had invaded cuticular.

梨黑星菌在叶片中寄生的具体位置是果胶层。V.nashicola对抗性、易感和非寄主材料的初期侵染相似，当真菌侵入角质层之后，亚角质层菌丝在易感材料中的增长速率远远高于抗性和非寄主材料，并且在抗性和非寄主材料上出现死亡菌丝，这些都表明抗性是在真菌侵入角质层之后表达的。

This paper reviewed microsclerotia or spores in soil are stimulated to germinate by host root exudates, hyphae colonizes on the surface of root, pathogens penetrate epidermis and develop in cortex, expand on stem and leaf, and symptom development, shows that host plant develops various barriers to restrain this fungus invasion.

The selective behaviour, fitness, cause formation and population differentation of the cotton aphid''s host biotype were studied on this project. The results showed that the cotton and cumbrits biotype aphid were existed in natural population in Nanjing .

本项目研究了南京地区棉蚜对寄主的选择与适应性、寄主专化型的成因、寄主专化型蚜在DNA水平上的多态性及棉蚜迁飞特性的种群分化、迁飞型种群的遗传响应与杂交遗传。

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。

Imagine, for example that there is one gene in parasites with two alleles p and P conferring two types of parasitic ability, and one gene in hosts with two alleles h and H, conferring two types of parasite resistance, such that parasites with allele p can attach themselves to hosts with the allele h, and P to H.

例如，想象一下，寄生虫的一个基因有两个等位基因p和P赋予两种类型的寄生能力，而寄主的一个基因有两个等位基因h和H赋予两类对寄生虫的抗性。带等位基因p的寄生虫可以将它们自已附在带等位基因h的寄主上，而带等位基因P的寄生虫可以将它们自已附在带等位基因H的寄主上。

The numerical and pathogenic variations of Ralstonia solanacearum distributed within the tissue of host plants were investigated for a preliminary study. Scientists discussed the relationship between the pathogen and the plant particularly from the point view of an ecological niche. The samples were taken in the fields of tomato, eggplant, tobacco, peanut and ginger in Fujian province.

［目的］通过分析青枯雷尔氏菌在不同寄主发病植株、在同一寄主不同侵染状态植株和同一寄主不同发病阶段植株体内分布及其致病力的异质性，从生态位角度来初步探讨该病原菌与植物之间的相互关系。

The seed beetle, Callosobruchus maculatus develops to the adult stage inside seeds before adult emergence, thus the larva or adult has an opportunity to obtain information about host traits, and this experience may influence the host preference of the adult.

四纹豆象为内食性昆虫，其幼虫及成虫羽化时均有机会获取关於寄主特性的资讯，进而可能影响成虫之寄主选择，故为检验寄主选择相关理论的极佳材料。
