产卵的

Ten dosages of La2O3 , 10, 20, 30, 40, 50, 60, 100, 150, 200 and 300 mg of La2O3 in 1 kg of wheat bran was used. Newly eclosion larvae and adults were continuously reared in the La2O3 food with different dosages.

用40mg氧化镧／kg麦麸的剂量处理79d后幼虫体重比对照组增加43％，同样的剂量使产卵高峰期的雌虫日平均产卵量增加59％，是最佳的处理剂量。

These fig wasps lay eggs into a syconium in a strict oviposition timing, for occupying the diverse niches, which reflect their different biological traits.

结果证明，鸡嗉果榕内生活的各种榕小蜂通过比较严格的产卵时序在榕果内产卵以占领不同的生态位，这反映了这些榕小蜂各自的生物学特性。

Papers dealing with the life stages of anadromous and catadromous species in estuaries and inshore coastal zones, theoretical papers, research papers, short communications and review articles, the proceedings of conferences and symposia are also published.

同时也刊载有关江口和沿海地区溯河产卵和为产卵顺流而下的鱼类的生命周期的论文，理论性论文，研究性文章，短通讯和评论性文章，以及会议与座谈会的会议记录。

This test studied some biological and bionomical characteristics of this pest, including life stages,developmental threshold and day-degree requirements,longevity,NO.

本文研究了西花蓟马的生活史、发育起点温度和有效积温、成虫寿命、产卵量和产卵规律、不同虫态的存活率、实验种群生命表、活动习性、危害特点、寄主选择性、种群动态等生物学和生态学特性，调查了西花蓟马在北京的分布、为害规律及嗜食特性等，并对色卡诱集技术、虫生真菌对该虫的致病性等一些防治技术进行了初步研究，主要结果如下。

Temperature is an important environmental factor which influences insects reproduction. In order to obtain the highest reproductive efficiency, Chrysopa septempunctata was fed with aphids at 15 #,25 # and 30 # respectively.The results indicated that oviposition period was prolonged obviously and oviposition quantity to a single female worm was the highest at low temperature of15#.

温度是影响昆虫生殖的重要环境因子，为了获得最高的繁殖效率，比较了在15℃、25℃和30℃的条件下用蚜虫做食料来饲养大草蛉，发现在低温15℃的条件下，单雌产卵量最高，产卵历期也较长。

The results indicated that the bioactivity(touch kill, oviposit inhibition, repellency)of methyl linoleate was high , the adjusted mortalities of female mite and egg were 82.82% and 78.54%, Oviposit inhibit ion rate and repellency rate were 78.46% and 95.61%,respectively at the concentration of 5 mg/ml.

亚油酸甲酯具有较强的触杀、产卵抑制和驱避作用，浓度为5 mg/ml时，对朱砂叶螨的雌成螨和卵24h后的校正死亡率分别达到82.82%和78.54%，LC50分别为1.4434mg/ml和2.0283mg/ml；对雌成螨24h后的产卵抑制率和驱避率分别达到78.46%和95.61%。

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。

The behavior time budget and activity rhythm of common coots in pre-laying and incubation period were studied in the tourism activities area and compare area of Anbang River wetland.Females spent more time than males feeding during pre-laying,and males spent slightly more time at defensive activities than females.Avoiding behavior were significant different between tourism area and compare area.

在安邦河湿地旅游活动区与对照区进行了产卵前期和孵卵期雌雄白骨顶的日行为时间分配和活动规律的研究，结果显示：产卵前期旅游活动区和对照区雌性取食时间比例均高于雄性，而雄性领域护卫行为较雌性的多；旅游区与对照区相比，白骨顶明显具有躲避行为。

This is not applicable for spawning Congo or African Flag Tetras where the spawning 'run' is fast and long, or some aggressive Tetras where larger tanks are better.

产卵缸可以是很小，但产卵进行得又快又长的刚果灯和非洲旗就不行了，一些好斗的脂鲤也是大点的缸好些。

During oviposition period, the male and female OAMs displayed certain tropism to the flowering rape and the milk vetch, the female OAMs performanced intense behavior of oviposition.

在产卵后，雌雄蛾都表现出一定的觅食行为，而雌蛾则更多的表现出强烈的产卵行为。

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％。
