寄主植物

The important plant pathogen with a wide range of hosts—— Colletotrichum Corda may cause severe agriculture economic losses.

摘 要：炭疽菌属Colletotrichum Corda 是一类重要的植物病原菌，寄主范围广，对农林生产危害很大。

There were 29 cultivated and 11 wild plant species under 16 families determined as its host plants and Cucurbitaceae,Solanaceae and Leguminosae were dominant.

在山西省调查结果，美洲斑潜蝇的寄主有29种栽培植物，11种野生植物，它们分属16个科，其中以葫芦科、茄科和豆科的种类居多。

Composicae, Solaceae, Cucurbitaceae, Cruciferae, Euphorbiaceae are the main families, such as eggplant, tomato, cucumber, collard, poinsettia and hibiscus etc..

虽然烟粉虱的寄主范围很广，但主要集中于番茄、茄子、黄瓜、甘蓝等蔬菜和一品红、扶桑等园林植物上。

Among the test cucurbitaceous host plants, cucumber was the most suitable host plant for B. tabaci.

综合比较4种葫芦科植物，黄瓜是B型烟粉虱的最适宜寄主。

In this review the current status of endophytic fungi in tropical area, resource diversity and host preference were focused on.

简要介绍了热带地区植物内生真菌研究概况、资源多样性、寄主选择，并对热带内生真菌生物多样性的发展前景作了分析。

Diet: The planting of food, often in groups of hosts in the Euphorbiaceae Mallotus, white gourd and other plants

食性：为食植性，常成群寄主於大戟科的野桐、白匏子等植物。

These closely related Gibberella species differ in their reproductive behaviors, geographic distribution and host ranges, plant pathogenesis, and production of toxins and other biologically active metabolites.

虽然它们是非常近缘的赤霉属各种，但在繁殖方式、地理分布、寄主范围、植物致病机理、毒素和其他生物活性代谢物的产生方面都有所不同。

Based on the investigations of rhizobia resource of Shaanxi, Gansu and Ningxia, the research applied polyphaic taxonomy to study the rhizobia isolated from Astragalus, Indigofera, Kummerowia and so on in the different levels.

本研究在陕甘宁地区豆科植物根瘤菌资源调查的基础上，利用多相分类技术，从不同层次水平系统地研究了分离自黄芪、木蓝、鸡眼草等寄主的根瘤菌。

H. armigera is a typical polyphagous insect. And its host plants include at least 60 crop species such as cotton, corn, wheat, soybean, tobacco and tomato and 67 wild plant species from about 30 plant families including Malvaceae, Solanaceae, Gramineae, Leguminosae, etc. H. assulta is an oligophagous insect and mainly feeds on tobacco and hot pepper in the field.

棉铃虫是典型的多食性昆虫，其寄主至少有60种作物，包括棉花、玉米、小麦、大豆、烟草、番茄等以及67种野生植物，涉及锦葵科、茄科、禾本科、豆科等30余科；烟青虫是一种寡食性昆虫，农作物中主要为害烟草和辣椒。

The toxin is a secondary metabolizable production in the pathogenic process of many pathogens,which can cause necrotic spot of the host. So it is a poisonous factor and it is important to the pathogenic activity.

毒素是许多亲和性植物病原菌致病过程中产生的次生代谢产物，离体使用可造成相应的寄主表现坏死斑反应，因此是病原菌的毒性因子，对决定病原菌的致病性有很重要作用。
