Meanwhile we also assayed the variation of the Bt protein in the larval body and dejecta. By voidance of dejecta, the level of Bt protein in the larval body was always lower than that in dejecta alter feeding for 12 h, and the difference between both reached the highest at 24 h after feeding.

Nymph is also a term for the larva of an insect with incomplete metamorphosis, and the young nymphet can be seen in this larval, immature term.

那么Humbert在本章节里对nymphets的描述发生在公园里就说的通了）"Nymph"还是一个用来表示蜕变不完全的昆虫幼虫，年轻的"nymphet"体现了从"幼小"、"不成熟"。larval的联系也会变得重要起来。

Morphology and Ultrastructure of Compound Eyes in the larval stages of Cherax quadricarinatus Morphology and Ultrastructure of Compound Eyes was investigated by TEM and SEM in the larval stages of Cherax quadricarinatus. The result is indicated: Morphology of compound eye and ommatidium in the larval stage were similar to that in adult stage. The area of the ommatidia increases from 906±29. 6μm〓 in larva Ⅰ(1. 5cm long) to 967±53. 3um〓 in larva Ⅲ(3cm long) and 3724±230.3μm〓 in adult (16cm long).

扫描电镜结果表明：刚离开母体的仔虾（体长约1cm）复眼和小眼的形态已接近成体，小眼的平均表面积由1.5cm仔虾的906±29.6um〓增长为3cm仔虾的967±53.3um〓和16cm成体的3724±230.3um〓；小眼个数也从体长1.5cm仔虾的1001个增加到3cm仔虾的1238个和16cm成体的5652个，红螯螯虾复眼的增大是由于小眼面积的增加和小眼数目的增多而引起的。

In this paper, we studied M. meretrix ferritin, cathepsin B and caspase genes, which are involved in clam larval shell formation, nutrition, metabolism and apoptosis, respectively. We have cloned the three genes, investigated the temporal and spatial expression profile both at gene and protein level in trochophore (L1), D-veliger (L2), pediveliger (L3) and postlarvae (L4). The potential roles of these proteins were analyzed with specific inhibitors during larval development. Firstly, embryos were found developed into trochophore-like larvae with no shell if cultured at gastrula stage in artificial seawater without iron. Shell-like structures were formed only in the presence of iron. The larvae which had been transferred at L1 stage into ASW developed normal shell. This indicated that iron and iron associated protein are important for larval shell formation. The EST sequence which is homologous with ferritin, which is a principal iron metabolic protein, was selected from the M. meretrix cDNA library. The full-length of ferritin subunit cDNA was cloned by RACE. The results of real-time PCR revealed that the MmeFer mRNA expression changed before and after the larval shell formation.

本论文以文蛤幼虫为研究对象，分别对文蛤幼虫发育过程中贝壳形成相关的铁蛋白、营养及变态相关的组织蛋白酶B及变态过程中细胞凋亡相关的caspase三个基因进行了克隆，分析了基因及编码蛋白在担轮幼虫期(L1)、D形幼虫期(L2)、壳顶幼虫期(L3)和稚贝期(L4)的时空表达特征，解析了其可能的功能，并研究了相应酶类的特异性抑制剂作用对幼虫发育过程的影响，进行了目标蛋白的功能验证，详述如下：研究结果显示，在文蛤胚胎发育到原肠胚时放入不含铁离子的人工海水中培养，发育成无壳的畸形，随着人工海水中铁离子添加浓度的升高，幼虫长出壳状组织接近正常状态；而发育到L1期幼虫放入不含铁离子的人工海水中培养却可以发育出正常的壳，推测铁和铁代谢相关蛋白在幼虫贝壳初始形成有重要的作用。

The pattern of lunar cycle can be classified into three strategies:(1) Planulation of S. hystrix and P. damicornis showed clear lunar periodicity and the peak of larval release shifted with different months. The peak of planulation occurred around the full moon in winter then shifted gradually to the first quarter moon phase in summer. The phase shift of larval release may be related to the seasonal variation of seawater temperature and the sudden temperature drops caused by upwelling.(2) Planulation of S. pistillata showed clear lunar periodicity and the peak of larval release occurred around the full moon.

在月周期方面可分成三种生殖策略：(1)尖枝列孔珊瑚与细枝鹿角珊瑚释放幼生不但有明显的月周期，而且释放幼生的高峰会随著月份而移动，由冬季至夏季期间，高峰从满月前后转变至上弦月前后；再由夏季至冬季期间，高峰从上弦月前后转变至满月前后，而此变动形成一个完整的年周期，原因可能与海水温度影响配子发育和胚胎速度与夏季期间涌升流所造成的降温有关。

In the artificial rearing larval honeybee method, 1-day-old larvae were reared in laboratory and 0.1 - 100 ppm pyriproxyfen was added in larval food. A dose respondent effect was found in the larval development of the treated larvae. Results showed that 0.1 ppm pyriproxyfen reduced the eclosion rate of the reared larvae conspicuously, and 1 ppm pyriproxyfen reduced that 84.6% of eclosion honeybee appeared the condition of deformed wings. The 10 ppm pyriproxyfen treatment caused 53.8% melanic death in the pupal stage, and no honeybees succeed in eclosion.

在室内饲养幼虫方面，分别添加0.1-100 ppm百利普芬於幼虫食物中，结果显示0.1 ppm百利普芬即会显著降低饲养幼虫的羽化率，而且添加1 ppm百利普芬会有84.6%羽化蜜蜂出现残翅现象；添加10 ppm百利普芬则会造成53.8%蜜蜂在蛹期黑化而死亡，而且无蜜蜂羽化成功；100 ppm百利普芬则有50%蜜蜂在幼虫期死亡，50%蜜蜂在蛹期死亡，亦无蜜蜂成功羽化。
