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。

Stylosa, but the pathogenicity of P II -3 was stronger than that of P I -1. The host range of P I -1 and P II -3 were the same. Their hosts were special to a certain extent. Only some species of mangrove such as Kandelia candel and Sonneratia apetala could be infected.

结果表明，菌株 P I -1和 P II -3均能引起红海榄赤斑病发生，但菌株 P II -3致病力比 P I -1的稍强；二者的寄主范围一致，均具有一定的寄主专化性，只能侵染部分红树植物如秋茄和无瓣海桑。

The changes of four indexes indicated that the photosynthesis and transpiration of poplar cultivars were influenced by the infection of Melampsora larici-papulina Kleb.

这4个基本生理指标变化说明，栅锈菌侵染寄主后对寄主的光合、蒸腾作用均有影响，而且在亲合性组合中影响显著。

It caused symptomless infection on garlic, onion, shallot, Welsh onion, Chinese leek, and pea, local lesions on Chenopodium amaranticolor, C. quinoa, and Tetragonia expansa, or systemic necrosis on broad bean, but did not infect leek, narcissus, lily, belldonna lily, tobacco (5 species), Gornphrena globosa, and Physalis floridana in host range test. The virus was propagated in Chinese leek and assayed in C.

其寄主范围包括大蒜、洋葱、葱、韭等葱科作物，但呈无病徵系统性感染，唯不感染韭葱；其他寄主反应包括：红藜、Chenopodium quinoa、及番杏接种叶的局部病斑，豌豆的局部潜隐感染，蚕豆的系统性坏疽等。

Only 27% of canal cutters with known host ranges are generalists that feed on plants in multiple families. The proportion of generalist canal cutters is similar or lower than estimates of generalists among phytophagous insects overall.

已知寄主范围的 canal cutters 中只有27%取食跨越多个科的寄主植物，此比例接近或低於整体植食性昆虫中评估为广食性者的比例。

The field tests indicated that: The lowest effective dosage of the gra-nulosis virus from Pieris brassicae in the control of the small white butterfly, Artogeia rapae was in a range of 2.3 × 1010- 3.4 × 1010 GIB/mu.

田同试验结果表明：大菜粉蝶颗粒体病毒防治甘蓝地上菜粉蝶幼虫的最低有效剂量在2.3×10~(10)～3.4×10~(10)颗粒体/亩之间；病毒的喷布应在寄主卵与低龄幼虫的高峰期进行，春夏季以在田间寄主卵孵化率近20％时使用为宜。

From the results of our studies we deduced that sucrose itself in the pith tissue of corn stalk could rule as a represser in someway to suppress the pathogen producing enzyme or toxin which can destroy host cells, or it could destroyor inactivate the enzyme produced by the pathogen, or it was not suitable for toxin surviving in it.

同时，从研究结果我们推断蔗糖本身可能具有阻遏镰刀菌产生酶类或毒素作用，病菌在侵染抗病品种过程中可能因寄主组织中蔗糖含量高，而导致病菌产生的可破坏寄主细胞组织的酶类受到阻遏或活性受到钝化；或者蔗糖不利于致病菌毒素的存活。

Parisite is hosted in the granular rhyolite, rhyolite and rhyolitic ignimbrite. The host rocks were formed in Late Early Cretaceous Epoch buried to depth of

氟碳钙铈矿的寄主岩为球粒流纹岩、流纹岩、流纹质熔结凝灰岩、流纹质凝灰岩，其寄主岩分布深度为2930~3830m，形成时代为早白垩世晚期。

Host resistance has been an elusive goal of many control programs. Most Sclerotinia diseases are not controlled principally by host resistance. However, some moderate levels of host resistance such as in dry beans and soybean have been found and can aid in integrated control programs.

在许多疾病控制程序中，获取植株的抗病性仍是一项艰巨的目标，大多数菌核病都不是由寄主的抗病性控制，然而，已发现了一些具有中抗水平的寄主如干豆和大豆，它们能较全面的控制菌核病。

The species of Sphingidae (Lepidoptera: Sphingidae ) in garden plants in Guangzhou and their hosts;2. Based on the study of species and hostplants of Sphingidae in Beijing,It is reported that there are 24 genus,38 species of SPhingidae distributing in this area,and indicates the existence of Langia zenzeroides szechuana in Beijing at the first time.

通过对北京地区天蛾的种类、数量及寄主植物的调查，首次报道北京地区共有天蛾24属38种及亚种，并且首次报道了川锯翅天蛾等种类在北京地区的分布，经调查，北京地区天蛾的寄主植物有27科，通过食性分析发现多食性种类占大多数。
