Feasibility study on application of DNA bar-coding technology in molecular identification of ScolytideaCO I gene of 15 bark beetle species collected from different regions and host is studied to discuss the feasibility of application of DNA bar-coding technology in Scolytidea molecular identification.

基于线粒体COⅠ基因的DNA条形码技术应用于小蠹科昆虫分子鉴定的可行性研究通过对采自不同地区、不同寄主的15个小蠹虫样本的线粒体COⅠ基因研究，对基于线粒体COⅠ基因的DNA条形码技术应用于小蠹科昆虫分子鉴定的可行性进行了探讨。

The bark beetle species on Pinus armandi and their niches were studied in the middle areas of Qinling Mountains. The results showed that 19 species of bark beetles infecting and damaging Pinus armandi in pine ecosystem of Qinling Mountains were found, but only 11 species of them could be competitive and coexistent one another.

通过对秦岭林区海拔1600-2200m的中山地带华山松小蠹虫种类和生态位的研究，结果表明：在秦岭林区入侵危害寄主华山松的小蠹虫有19种，其中能构成竞争和共存的小蠹虫主要有11种。

Xanthomonas campestris pv. campestris is the causal agent of black rot disease of crucifers worldwide. In both plant and mammalian Gram-negative pathogenic bacteria, type III secretion systems, encoded by hrp cluster, play a crucial role in interactions with the host. The proteins assembled TTSS were highly conserved.

野油菜黄单胞菌野油菜致病变种是一种能在全球范围内引起所有十字花科植物黑腐病的重要病原细菌。hrp基因簇编码的Ⅲ型分泌系统在动植物病原细菌和寄主互作过程中起着极其重要的作用。

It is an important biological agent to control cotton bollworm in the cotton field by parasitizing rate at 22.9%.

其寄主范围非常广泛，该蜂对棉铃虫各世代的平均寄生率可达22.9 %，是棉铃虫田间生物控制的重要因子。

At this stage, if left undetected, the maggot will pop its way out of the small hole that it has eaten inside of the host and fall to the ground where they pupate into an adult botfly in about 20 days time.

如果在这一阶段它不被发现，蛆就会从那个从内部吃掉寄主的小洞里跑出来，掉到地上作蛹，在二十天的时间里变成成年马蝇。

The hole in which the botfly maggot has carved itself in the host's tissue serves as a breathing passage for the larva.

马蝇蛆自己在寄主身体组织上挖出的小洞是幼虫的呼吸通道。

The stromas of them can be distinguished by the following features: the stromas of Cordyceps nigrolla has few branches and the largest diameter in these 8 kinds of Cordyceps while each stroma of Codyrceps sobolifera has branches and the diameter of stroma of each branchlet is comparatively smaller.

拟黑虫草和蝉花虫草的寄主相似，二者菌核最为粗大，但子座有所区分，拟黑虫草子座少有分枝，在这8种虫草中子座直径最大，蝉花虫草子座都有分枝，未见单枝者，且每一小枝子座直径较小

Some reports indicate reduction of legume BNF by mineral N is dependent on host species and form of N available.

一些报告还指出，通过矿质氮引起的豆类作物生物固氮的减少与寄主品种和有效氮的形态有关。

Capsid proteins are involved in recognition and infection of the host and can be used to identify the virus by serological means or amino acid sequencing.

衣壳蛋白与寄主的识别和感染有关，还可以通过血清学的方法或氨基酸序列来识别病毒。
