They are not only involved in the process of fungal development and differentiation, such as supplying nutrition, for the growth of mycelium, attaching themselves to the morphosis and alteration of the cell wall of hyphae, as well as taking part in autolysis of filamentous fungi, but also show an important role in the process of pathogenesis including touching and cling on to the cell wall o.

1，3-葡聚糖酶(β-1，3-glucanase)是一类能够水解β-1，3-葡萄糖苷键的酶，普遍存在于多种真菌中，它们不仅在真菌生长发育起重要作用，如为菌丝体生长提供营养、参与菌丝体细胞壁的形态建成和构象的改变、参与菌丝体自溶等，而且在病原菌入侵寄主植物与致病的过程中扮演着重要角色，如：参与接触和吸附寄主细胞壁；破坏包围病原菌入侵结构的乳突。

Under laboratory conditions,SBPH population\'s life cycle was observed which rearing in different host plants,such as Wu yujing No.3,Eryou No.084, Er you No.42,Xu dao No.3,Yan dao No.8,Yang mai No.12(YM-12),Barnyard grass and Stephanotis,then,the SBPH\'s life table was estabished.

The spore could germinate in 5-35℃,the optimum temperature was 25℃.The bioassay of toxin used seeding and young leaves because it could cause the evident symptom rapidly and sensitively. The toxin produced by A, tenuis Nees could change the function of the toxin on the POD, SOD and PAL was identical to A.

病原菌毒素的生测采用寄主植物切根苗、幼嫩叶片比较直观、灵敏；毒素对寄主植物膜透性有伤害作用，引起膜功能紊乱；毒素和病原菌对枸杞叶片处理后，对POD、SOD、PAL酶活性的影响有很大相似性。

Anoplophora glabripennis Motshulsky (Coleoptera: Cerambycidae) is one of the most destructive insect borers of poplar trees in China. In recent years millions of poplar trees were damaged to death or near death in"Three-North Area", which caused heavy losses economically, ecologically and socially. Through the study on host selecting behaviors and behavioral responses to plant volatiles of A.

At the same time information index showed genetic diversity index (0.3456) of great ball horned toad Wrinkle is greater than that (0.3456) of Eulecanium gigantean Shinji big balls horned toad.This shows the genetic diversity of big ball horned toad Wrinkle is rich .

扁平球坚蚧在白蜡和刺槐两种不同寄主植物种群之间存在一定程度的差异，这种差异与扁平球坚蚧的生物学习性和寄主植物有关。

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 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。

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.

本文系统探讨了土壤中微菌核或孢子受寄主根系分泌物的刺激，开始萌发、产生的菌丝在寄主根表面定殖、穿过表皮、在皮层中发生及在寄主体内扩展和症状形成等黄萎病菌侵染棉花的过程，阐述了寄主植物形成多级防御反应阻击病原菌的入侵。

In this study, I used kidney bean to rear L. trifolii stock at 24.5 ± 1C, 70 ± 10% R.H., photoperiod 12L : 12D and offered beggar-tick, kidney bean, rape, and tomato as foods for females to test their host preference. The results showed that females exhibited significantly feeding and ovipositional preference on beggar-tick, and larvae ate in kidney bean have highest pupal weight, survivorship and emergence rates.

本研究以菜豆做为维持非洲菊斑潜蝇母族群的寄主植物，在24.5 ± 1C， 70 ± 10% R.H。， 12L ： 12D的环境下，让非洲菊斑潜蝇对大花咸丰草、菜豆、油菜、番茄这四种寄主植物进行产卵及取食偏好性测试，发现雌虫对大花咸丰草存有显著的取食及产卵偏好，而在菜豆上取食的幼虫具有最高的蛹重、存活率及羽化率。
