Under the condition of feeding honey, the laying eggs occupies 68% of whole eggs in the first day of eclosion, the average laying eggs rate was 65.79%.

在喂食蜂蜜的条件下，羽化第一天产卵占整个产卵量的68%，平均产卵率为65.79%。

P. pilosa oviposits in the same day as the fig wasp pollinators, and they can oviposit on the sycouia for two days. Philoirwesis sp. oviposits much later, 6 to 13 days later than the pollinators. The ovaries inside the post-floral phase male syconium of F.

短尾佩妃延腹小蜂的产卵时间与传粉榕小蜂接近，几乎与传粉榕小蜂同时到达隐头果产卵，该时期隐头果可供其产卵2天；而长尾佩妃延腹小蜂的产卵时间较晚，在传粉榕小蜂产卵后的第6天开始到果外产卵，并可持续产卵约一周时间。

A few days after mating, females begin to lay their eggs, using an ovipositor to slice into branches. She leaves behind scarred trees hundreds of eggs in deeply-cut slits.

在交配后数天，母蝉开始产卵，用产卵器将树枝切开并产卵进去，她留下了数以百计卵在深深地树缝里。

The results indicate that female wasps deposit HMPs on the chorion of host eggs with her ovipositor near the end of egg-laying process. Na ye females do not posses the ability for recognizing the marking pheromones and have to obtain the ability though the learning process, in which the wasp inserts her ovipositor into a host egg to determine whether the egg has been parasitized followed by antennal drumming on the exterior. Once the learning process is completed, the female wasp will be able to discriminate between parasitized and unparasitized hosts and reject a parasitized egg by simply drumming on the exterior of the egg. Learning plays an important role in reducing initial rejection time when an unsuitable host is encountered. Female wasps of T. astriniae can quickly learn to associate the presence of a HMP on host egg chrion with the internal status of the egg.

研究结果表明，玉米螟赤眼蜂的寄主标记信息素是在其产卵过程中的收场阶段由产卵器产生的，并且标记在寄主卵表的化学物质；玉米螟赤眼蜂对标记信息素的识别不具有先天性，其必须先用产卵器插入寄生卵来检测是否被寄生，然后其触角不停地敲击，通过学习获得对标记信息素的识别能力，从而放弃了对寄生卵的选择，学习对初始放弃时间有着重要影响，改善了其对寄主搜索效率，这种学习行为是与寄主联系在一起学习的，它能根据寄主被寄生与否而对标记信息素作出反应与不反应。

The experiment of oviposition preference of bean pyralid on soybean varieties was conduct in net room. The number of eggs laying on susceptible genotypes were significantly more than those on resistant genotypes.

在人工接虫条件下，研究豆卷叶螟在不同抗性大豆品种上的产卵选择性，结果显示豆卷叶螟在感虫品种上的产卵量显著多于在抗虫品种上的产卵量。

The 6 saury landed size-classes of Taiwan can be assumed as 4 groups: Extra-large, No.1 and No.2, No.3, and No.4 and No.5 size-classes, which could roughly correspond to the 1 + year-class, and the autumn, winter, and spring spawned cohorts of the 0 + year-class, respectively.

这六种台湾缷鱼规格之秋刀鱼，可被归属成四群：特大型群、一号型与二号型群、三号型群、及四号型与五号型群。这四群鱼大约可分别对应为1+龄年级群、0+龄年级之秋季产卵群、冬季产卵群及春季产卵群。

The biological characteristics and parameters for different geographic populations of Anastatus japonicus Ashmead in the eggs of Antherea pernyi were compared with the method of life table. The results show that the fecundity properties parameters of Vietnamese population including the net reproduction rate (R0), intrinsic rate of increase, finite rate of increase, doubling time, number of eggs laid per female, preoviposition period and oviposition period are superior to Guangxi, Guangdong and Hainan population.

应用生命表技术对荔蝽平腹小蜂Anastatus japonicus Ashmead不同地理种群以柞蚕卵为繁殖寄主的条件下的重要生物学指标和参数进行测定和比较，结果表明，越南种群的主要生殖力指标，包括净生殖力（R0）、内禀增长率、周限增长率、种群倍增时间、单雌产卵量、产卵前期和产卵历期均比广西、广东和海南种群的理想；4种群的雌蜂寿命、羽化率和雌性比率则没有显著差异。

Before ovulation, the oviducal wall is the thickest, the simple tubular glands in lamina propria are filled with the jelly substance. After ovalation, the oviducal wall is the thinnest, the cells of the tubular glands becomes smaller. During ovulation, the lamina propria is thicker. Before ovulation and after ovalation, the change of serosa is not distinct.

产卵前，输卵管管壁最厚，固有层中的单管状腺充满胶质；产卵后输卵管管壁变薄，固有层腺体细胞缩小，粘膜层在产卵时比产卵前明显增厚；产卵前和产卵后浆膜层无明显变化，产卵时厚度明显变薄。

When the spawning weight range from 0.1～2.0g,it has the positive correlation with hatch amount,but when the spawning weight exceeds 2.0g,hatch amount will reduce.(5) Analyse the content of heavy metals and pesticide residues for soil and aquaculture water in W.pigra with the help of atomic absorption spectrophotometers,atomic fluorescence spectrophotometers and gas chromatography.

结果表明，蚂蟥产卵和孵化的最适温度为25℃，产卵的最佳体重为20g左右；温度能影响蚂蟥产卵前后的体重，而体重大小对产卵前后体重变化影响不明显；当卵重在0.1～2.0g之间时与孵出量成正比，当卵重大于2.0g时孵出量反而有所下降。

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%.
