幼虫

It was not cross- reaction with Entamoeba histolytica and Schistosoma japonica.It is a simply and better method to extract the DNA with lysine boiling.

结果 经扩增于500bp、670bp、1200bp出现特异性片段，与原选择的编码基因片段大小相同，此特异片段与溶组织内阿米巴、日本血吸虫DNA无交叉反应，不同的DNA提取法结果显示：用裂解煮沸法同样可从仅含1条旋毛虫幼虫的25μl正常小鼠血浆中扩增出特异性片段。

The giant jellyfish exhibit two types of reproduction, one is asexual reproduction, including fertilized eggs, planula, scyphistoma, podocyst, strobila and ephyra; the other is sexual reproduction, including medusa or jellyfish, typically solitary, pelagic.

Objective To investigate the killing effects of different extracts of Euphorbia kansui Liou Mass and Dryopteris Crossirhizomz on mosquito larva.

目的 了解甘遂和贯众不同提取液对蚊幼虫杀伤的作用。

Results The killing effects of different extracts of Euphorbia kansui Liou Mass and Dryopteris Crossirhizomz had big differences.

结果 2 %甘遂和贯众草药的乙醚、乙醇提取液对致倦库蚊幼虫的杀伤分别高达 95 0 %± 4 4 %，90 0 %± 3 5 %，83 0 %± 0 6 %与 75 0 %± 2 0 %。

Shining light selectively on one eyespot changes the beating of the adjacent cilia. The resulting local changes in water flow are sufficient to alter the direction of swimming, computer simulations of larval swimming show.

计算机模拟幼虫游动图像显示：闪烁的光线在眼点上分布不均，这样就改变了临近纤毛拍打海水的幅度，由此引起的海水浮动足以改变生物游动的方向。

Studying the larvae of the marine ragworm Platynereis dumerilii, the scientists found that a nerve connects the photoreceptor cell of the eyespot and the cells that bring about the swimming motion of the larvae.

研究人员以沙蚕环节动物-岩虫幼体进行研究，发现一个神经连接着眼点光感细胞和控制幼虫游泳的细胞。

Purified Ricin revealed high toxicity to mouse, but had no any toxicity to Prodenia litura Fabricius larvae.

动物实验表明该蓖麻毒蛋白对小白鼠有较强的毒性，但对斜纹夜蛾幼虫无毒杀作用。

When You collect all spheres you need to feed the larva with this food.

当您收集的所有领域，您需要饲料的幼虫，这与食物。

Objective:To establish a new method for gene detection of Brugiamalayi larvae in mosquito and use it in filariasis surveillance.

目的：探索蚊体内马来丝虫幼虫基因检测的新方法，并用于丝虫病监测。

The nauplii of crustacean Artemia, also named brine shrimp, are the most widely used live zooplankton bait for feeding larvae of aquaculture finfish and shellfish.

甲壳类生物丰年虾(Artemia sp。)的无节幼虫，又称为盐水虾，是最广泛用於餵食养殖鱼贝类幼苗的活体浮游饵料生物。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
