寄主

Alternatively, the spectral softening above 2 GeV could be due to gamma-ray absorption via photon-photon pair production on the soft X-ray photon field of the host active galactic nucleus, but such an interpretation would require the dissipation region to be located very close (l~100 gravitational radii) to the black hole, which would be inconsistent with the X-ray spectrum of the source.

另外的关于2 GeV以上能谱变软的可能解释是高能光子和寄主活动星系核的软X射线辐射场通过电子对产生反应而被吸收，但是这个解释要求反应区域要很靠近中心黑洞(1~100倍引力半径)，这和3C 454.3的X射线测量谱相矛盾。

The ailanthus plants werenot primary source host for ZYMV,WMV,PRSV-W and CMV.

首次证明臭椿在葫芦科作物病毒流行中不能作为其主要病毒ZYMV、WMV、PRSV-W和CMV的毒源寄主。

Alternaria is a dematiaceous mitosporic fungus with a wide variety of habitats and geographical distribution.

链格孢是半知菌暗色丝孢菌中重要的一类真菌，该属真菌种类多，寄主范围和地理分布广泛。95%以上的种能兼性寄生在植物上，是重要的植物病原菌。

Any of numerous small parasitic nematode worms of the family Ancylostomatidae, having hooked mouthparts with which they fasten themselves to the intestinal walls of various hosts, including human beings, causing ancylostomiasis.

钩虫钩虫属的大量小的寄生线虫，嘴部有倒刺，可以固定于寄主内脏壁上，能引起钩虫病

The name derives from the characteristic yellow-brown streaks that appear on the host epidermis.

它在寄主表面产生大量孢子，使寄主植物出现黄褐色的条纹，如同生锈。

But this gut worm doesn't slow them down. In fact, infected shrimp eat 30 percent more prey than those that are parasite-free.

而这些寄生虫不但没有抑制寄主们生长，反而让寄主们胃口大开，要比未被寄生多吃30%。

Furthermore, based on the data of larval survival being influenced by host size, the adaptation of host size discrimination by the seed beetle was explored.

文中进一步根据寄主大小对幼虫存活影响的资料，探讨四纹豆象对寄主大小辨识之适应意义。

The aim of this study was to reveal the host-choice mechanism of the seed beetle, Callosobruchus maculatus , under a condition when different hosts are provided.

本文主要探讨四纹豆象在面临不同种类之寄主时，其产卵的寄主选择反应为何？

The results indicated that whitefly populations were able to improve the host performance dramatically since continuously feeding on particular host species, but the improving process was different among the host plants.

结果显示，烟粉虱种群能够随着取食经验的积累而快速提高寄主适应性水平，但是不同寄主之间存在很大的差异性。

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。
