The results indicated that the transgenic sck+cry1Ac rice did affect not only the mortality and body weight of the stripped stem borer, but also some biological characteristics of its parasitoid A. chilonis.

结果表明转sck+cry1Ac基因水稻不仅对二化螟生长和存活有显著影响，而且可经寄主二化螟影响到二化螟绒茧蜂的一些生物学特性。

Host plants affected the survival, development time and reproduction of P.xylostella and indirectly affected the survival, development time, fecundity and sex ratio of the parasitoid.

6小菜蛾及菜蛾绒茧蜂的生存、发育、繁殖等均不同程度地受寄主植物的影响，小菜蛾成虫期的产卵嗜好性并不反映植物对其幼虫期的相对适合度。

Electroantennogram responses of the generalist parasitoid Campoletis chlorideae Uchida to a range of plant volatiles and host pheromone gland compounds were investigated.

Various of phage in the corresponding Host cells performed characteristics of its own based on the difference between phages.

各种噬菌体在其相应的寄主细胞上表现其本身的特征，是区别噬菌体的一个依据。

During its growth and invasion in the host, it can produce phytotoxin, pectinase and cellulase to overcome the tree resistance and stain the host's tissues to blue, inducing the disease symptoms, such as phloem necrosis, namely phloem reaction zone, etc.

该菌在云南松体内的生长侵染过程中，将产生毒素和分泌纤维素酶、果胶酶等酶类以突破寄主组织的防御屏障，使云南松组织发生蓝变，产生病害，诱导形成韧皮坏死区域等症状。
