The over-all conclusion that must be drawn from the disarrangement experiments are first, that motor coordination (and certain behavior patterns dependent upon it) is driven by a rigid, unalterable cycle of neurophysiological events inherent in a species' central nervous system; second, that larval, fetal, or embryonic tissues lack specialization; this enables these tissues to influence one another in such a way as to continue to play their originally assigned role despite certain arbitrary peripheral rearrangements.
全面性的结论,即必须先从未安排的实验描绘,动作协调(取决於它的某些行为模式)是僵硬的,像是不可改变的周期神经生理活动中,其中所固有物种的中枢神经系统;第二,那幼虫,胎儿或胚胎组织缺乏专业化,这使这些组织影响专业化的另一种方式,尽管某些周边重新排列,还是继续发挥其原来分配的作用。

This is the ultimate horror lurking beneath the surface of the city: the grotesque, bloated Hive Mother and her thousands of man-sized larvae, cocooned in labyrinthine tunnels, fed by the sewage that flows through the tunnels.
这是最终隐藏在这座城市表面下的恐怖:奇形怪状的浮肿的母蜂和她的成千上万的man-sized幼虫群体,包裹着错综的隧道,隧道内的污秽喂养着他们。

The main results and conclusions are as followings.1, The histone deacetylase inhibitors were used to feed the larve of the fly, and then the polytene chromosomes were observed under the microscope.
得到的主要结果和结论如下: 1,通过用去乙酰化酶抑制剂处理果蝇幼虫,观察果蝇多线染色体在热休克基因处的形态变化,发现去乙酰化酶抑制剂介导的乙酰化水平的升高可引起染色体结构的显著变化,推测乙酰化修饰不仅影响分子间的相互作用而且还可以影响染色体的高级结构。

A new picorna-like virus was isolated from dead Evtropis oblique larvae deceased from NPV infection. Electron microscopic observations of purified virions were non-enveloped isometric particles with diameter of 26nm. The virions contain two capsid proteins: 31.5kDa and 28.8kDa, the amount of later is 2.5 times more than that of the former. Analysis of 3′terminal sequence of EoPV clone identified that it can encode RdRp and has eight conserved motifs. Homology analysis shows that it is closely related to Perina nuda picorna-like virus.
从核型多角体病毒感染致死的茶尺蠖幼虫尸体中分离到一株微小RNA病毒透射电镜观察纯化的病毒粒子为无囊膜、无表面特征、直径约26nm的球状颗粒。16%的SDS-PAGE显示它有两个分子量为31.5 kDa和28.8 kDa的衣壳蛋白,后者的含量是前者的2.5倍。3′端克隆序列分析表明EoPV基因组3′有poly尾,编码RNA聚合酶,含有微小RNA病毒RNA聚合酶的八个保守基序,同源性分析表明它与榕透翅毒蛾微小RNA病毒亲缘关系最近。

Results showed that abundance, richness and diversity of arthropod communities decreased with depth. A negative association was found between canopy openness and the number of arthropod groups in the lifter layer; some arthropod taxa, such as the Uribatida, Prostigmata and Mesostigmata, were found in a wide range of light conditions, whereas the Hymenoptera, Symphyla, Pseudoscorpiones and Lepidoptera larvae may be photophobic.
结果表明土壤节肢动物的多度、丰富度和多样性随土壤层的加深而下降,具有明显的表聚性;林冠开度与凋落物层的土壤节肢动物类群数量呈负相关;甲螨亚目、中气门亚目和前气门亚目动物对光照的适应范围广;膜翅目、鞘翅目幼虫、综合纲和伪蝎目动物具有明显的避光性;土壤节肢动物类群的分布与林冠开度、土壤自然含水量、电导率和有机质关系密切。

The silkworms, which propagate themselves by ova, grow in the from of larvae and when mature after 4 times of exuviations (about 25 days), they begin to spin silk 0.35g Per worm into cocoons, On completion of this, the worms, having sloughed once again are transformed into chrysalises in the cocoons.
从古代开始,在茂密的桑树中,蚕便一如既往的产卵繁殖,随着一个个完全不同的形态学特征的出现,蚕经历了从蚕卵到幼虫再到成虫的艰辛的成长过程,在整个过程中,蚕将蜕 4 次皮(大约每隔 25 天一次),接着他们开始土丝来完成茧,当蠕虫与茧达到 0.35 克之后,艰难爬行的蠕虫变成为在茧中的蝶蛹。

Figs and their pollinating wasps constitute the extreme example of interactions between plants and insects. Each fig species is pollinated by a single minute, pollen-bearing female wasp species that only depend on the particular fig syconia for the production of their offspring, so the relation is generally regarded as species-specific.
榕树-榕小蜂的互惠共生是植物与其传粉者间相互作用的最极端的特例,几乎每一种榕树均由榕小蜂科的一种特定昆虫传粉,而它们的小蜂也只能在此特定榕树种的花内养育它们的幼虫,构成了高度的种专一性。

The results show that eggs dissected from the lateral oviducts may cleave in the culture medium composed of TC - 100, plasma of larvae of its host Ostriniafurnacalis and fetal serum.
通过在体外条件下培养腰带长体茧蜂侧输卵管处解剖得到的脱去滤泡细胞的成熟卵及从寄生早期幼虫血淋巴中获得的初期胚胎,对腰带长体茧蜂卵和胚胎的初期发育进行了初步的研究。

A healthy worker bee spends about four weeks in its hive, feeding on protein-rich pollen and nursing larvae, and then another two weeks in the field eating sugary honey until its proteins are depleted and it dies.
一只健康的工蜂要在蜂房里度过四周的时间,一边以富含蛋白质的花粉为食,一边养育蜜蜂幼虫;然后再在野外生活两周,采食含糖的蜂蜜,直到体内的蛋白质耗尽,然后死亡。

In this study, I used kidney bean to rear L. trifolii stock at 24.5 ± 1C, 70 ± 10% R.H., photoperiod 12L : 12D and offered beggar-tick, kidney bean, rape, and tomato as foods for females to test their host preference. The results showed that females exhibited significantly feeding and ovipositional preference on beggar-tick, and larvae ate in kidney bean have highest pupal weight, survivorship and emergence rates.
本研究以菜豆做为维持非洲菊斑潜蝇母族群的寄主植物,在24.5 ± 1C, 70 ± 10% R.H。, 12L : 12D的环境下,让非洲菊斑潜蝇对大花咸丰草、菜豆、油菜、番茄这四种寄主植物进行产卵及取食偏好性测试,发现雌虫对大花咸丰草存有显著的取食及产卵偏好,而在菜豆上取食的幼虫具有最高的蛹重、存活率及羽化率。
