产卵

Similar to Atlantic salmon, but unlike their Pacific Oncorhynchus kin, steelhead are iteroparous and may make several spawning trips between fresh and salt water.

与大西洋鲑类类似，但不像他们的太平洋大马哈鱼近亲，刚头可以在幼态与性成熟态之间转换，在海水和淡水之间完成数次产卵旅程。

Any of various large food and game fishes of the genera Salmo and Oncorhynchus,of northern waters,having delicate pinkish flesh and characteristically swimming from salt to fresh water to spawn .

大麻哈鱼北部海域中□属和大麻哈鱼属的各种大食鱼或猎物鱼，具有柔嫩粉红色肉，特征是从咸水游到淡水中去产卵

Larger larvae or adults overwinter and lay eggs during May.

以大龄幼虫或成虫越冬，5月份产卵。部分个体一年可发生2-3代。

There has been lots of researches on 5-HT's role in Caenorhabditis elegans feeding, oviposit and locomotion behavior, however no research was about mechanisms on C. elegans learning and memory regulation.

迄今，在线虫中有诸多关于5-HT参与调控线虫的进食、产卵以及运动等行为的报道，然而有关5-HT参与调控线虫的学习记忆行为方面未有涉及到。

Methods According to the ecological characters of, Aedes albopictus ,and the structure of CDC ovitrap and housefly trap,we invented a Mosqovitrap in which the mosquito would be attracted to oviposit,and would be caught.

方法根据白纹伊蚊的生态特点和美国疾病预防与控制中心诱卵器监测方法，结合捕蝇笼结构特点，设计具有引诱伊蚊产卵的器械，并在实验室及现场进行验证。

When tHe female have taken enough blood and dropped from donkey's body,they wereput in incubator to oviposit and incubated at 28℃ and 90%RH.

将实验室培育的&清洁&草原革蜱饥饿成虫，饲喂在人工感染驽巴贝斯虫的驴体上，俟雌虫饱血脱落后，置28℃、相对湿度约90％的培育箱中产卵孵化

Methods According to the ecological characters of Aedes albopictus , and the structure of CDC ovitrap and housefly trap, we invented a Mosq ovitrap in which the mosquito would be attracted to oviposit, and would be caught.

根据白纹伊蚊的生态特点和美国疾病预防与控制中心诱卵器监测方法，结合捕蝇笼结构特点，设计具有引诱伊蚊产卵的器械，并在实验室及现场进行验证。

Results: WildAnopheles sinensis in Zhengzhou could develop, survival, suck blood, mate, fertilize and oviposit smoothly in laboratory.

结果：郑州野外的中华按蚊在实验室内交配、受精、吸血、产卵、各期发育、存活均已顺利进行，累代养殖获得成功。

Digested by endonuclease, the linear plasmid was injected into the copulatory pouch of the female moth and the sperm reservoir of the male moth. Let them mate with the normal moth and oviposit.

将打靶质粒酶切线性化后，分别注入到雌蛾交配囊和雄蛾贮精囊，与正常蛾交配产卵，分析外源基因在当代的情况。

Mosquitoes captured and the egg positive traps were counted and recorded every day. Results Comparing with the control group, yeast-generated CO2 could take a strong attraction to mosquitoes in the field (P.05), but had an adverse effect in laboratory. P. maximum infusion, tyre infusion and L-lactic acid dilution could not attract Aedes albopictus to oviposit in Mosq-ovitrap. The colour change of Mosq-ovitrap could not raise its attractant ability to mosquitoes, on the contrary, increase the probability of mosquito escaping from Mosq-ovitrap.

结果 实验室和现场的结果显示，酵母发酵产生的CO2在室内实验中没有增强诱蚊诱卵器的诱蚊效果，而在现场实验中却产生较好的诱蚊作用，实验组的诱蚊指数和诱蚊密度指数与对照组比较差异均有统计学意义(P.05)；大黍叶、轮胎浸出液和乳酸稀释液在试验中未显示出吸引白纹伊蚊雌蚊产卵的能力；在改变诱蚊诱卵器杯身颜色的试验中，杯身上2/3变为黑色并不能提高它的诱蚊和诱卵能力，反而增加成蚊逃逸的概率。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
