产卵

There are 2 main pathways by which schistosomes cause NS: egg embolism and worm migration, via either artery or vein system, especially the valveless perivertebral Batson's plexus. The adult worm migrates anomalously through the above pathways to the CNS where they lay eggs.

关于中枢神经系统血吸虫病虫卵入侵途径，目前主要存在虫卵栓塞和成虫产卵两种学说，前者分为动脉栓塞、静脉栓塞和Batson椎静脉途径，成虫亦可循上述途径入侵中枢神经系统产卵。

An endangered species now, green turtles laid their eggs on the beach in Taiwan in the past. Recently, only a few reserves are left. Wangan Green Turtle Tourism and Conservation Center is one of them where more green turtles regularly come to lay eggs.

绿蠵龟现被列为保育类动物，过去台湾本岛许多沙滩，均有绿蠵龟上岸产卵的记录，如今却只剩下极少数地方，望安乡的绿蠵龟保护区，是目前数量较多且较稳定的产卵栖地。

And these estrogens,depending on the level of wastewater treatment,may not be completely broken down during sewage treatment,so they get discharged into rivers and streams.male fish exposed to the hormone become feminized,they produce the same proteins that female fish do to develop eggs,some males even develop eggs in their testes.

妇女自然而然地分泌雌激素，然而她们服用的避孕药中隐藏着人造的雌激素。这些雌激素可能在污水处理过程中不能彻底地清除，被排入河水和溪流。雄鱼在荷尔蒙的作用下雌化，产生了雌鱼产卵前生成的蛋白质，一些雄鱼甚至在睾丸中产卵。

This pest has one generation per year. The larva overwintered in the soil, and pupated at the last ten days of March to the first ten days of April in the soil layer of 3-10cm under the ground. The pupal period ranged from 12 to 17 days.

此虫一年一代，以幼虫在土中越冬；翌年3月下旬至4月上旬在3—10厘米土层内化蛹，蛹期12—17天；4月中、下旬成虫出土上树取食桑芽和叶片，交尾后2—7天产卵在枝顶及春季剪梢口下段等处，每头雌成虫产卵44—205粒，卵期15—19天；初孵幼虫入土取食植物。

The results show that Abstract Ericerus pelahas has one generation a year, overwinters by the fertilized femaleadults. It stars to feed and grow in forest march,spawning peak in second or late April.The larva are hatched in second or late May. It goes toleaves and then goes to stem in forest or second June. The male emerged in the second or late October dies after it male with it overwinters in November.

结果表明该虫1年发生1代，以受精雌成虫越冬，翌年3月上旬开始继续取食、生长， 4月中、下旬为产卵盛期，产卵期10~13 天，5月中、下旬为若虫孵化期， 6月上、中旬为若虫定叶、定杆期， 10月上、中旬雄虫羽化与雌成虫交尾后死亡，受精雌成虫11月中旬停止取食开始越冬。

On the condition of complementary nutrition at the adult stage, the average egg numbers oviposited by one female of cotton bollworm which fed cotton leaf, cotton boll and artificial diet at.

在成虫期有补充营养条件下，幼期取食棉叶、棉铃和人工饲料个体的平均单雌产卵量分别为565.2、1005.8和1052.2粒；成虫期无补充营养，则单雌产卵量依次为162.2、400.6和1035.6粒。

The female weevils oviposited on mung beans as well as adzuki beans in no-choice test, while they preferred adzuki bean over mung bean in choice test. To study the relationship between oviposition behaviour and host preference, three treatments (A: pure adzuki beans; M: pure mung beans; Mixed: mixed adzuki beans with mung beans) were provided to the female.

过去的研究报告指出，雌豆象成虫利用相对法则检视寄主品质，以决定是否产卵於寄主豆上；而且在非选择性试验中，雌虫产於绿豆或红豆的卵数相等；但在红、绿豆选择性试验中，雌虫则偏好产卵於红豆。

We found that the female's handling time before ovipositing on mung beans in treatment M and adzuki beans in treatment A were the same, but it is longer on mung beans in Mixed treatment than that of treatment M.

本研究透过观察雌虫在全红豆组、全绿豆组以及红、绿豆混合组中的产卵行为来厘清产卵行为和寄主偏好之间的关系。

Here, we examine MOSQUITOFISH CHEMICALS AND Culex OVIPOSITION 799 whether ovipositing mosquitoes can detect the presence of a predatory fish using only chemical cues.

在这里，我们审视 mosquitofish化学品和库蚊产卵799 是否产卵，蚊子能够探测存在一种肉食性鱼类，只用化学线索。

The wasp prefer to laying in the female scale during before ovipositing with eggs.

观察还发现，友恩蚜小蜂可在自己、同种或异种小蜂产过卵的松突圆蚧上产卵，嗜好孕卵期的雌蚧上产卵。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
