滞育是一种广泛存在的生物学现象，可以发生在昆虫、鱼类、两栖动物甚至哺乳动物中。家蚕是重要的卵滞育模式昆虫，卵壳是昆虫胚胎重要的保护层，并且对胚胎发育阶段的呼吸生理也具有重要的作用。本文采用即时浸酸法和DMSO 法处理了刚产下的蚕卵，成功的阻断了蚕卵滞育的发生。通过SEM 扫描电镜对其卵壳表面及气孔进行观察分析发现了一系列的变化，特别是卵壳表面“脂质”脱落物出现和气孔直径增大趋势。我们推测这些变化可
Dissolution is an important part of silk fibroin(SF)reprocessing,and it is the only way to process it into films,gels,porous scaffold materials,and electrostatic spinning silk fibers.There are a varie
昆虫躯干外着生有一系列附属器官，主要包括背侧附器和腹侧附器，其中腹肢的多样性表现尤为突出。腹肢的发育过程受到多种调控因子的作用。本文就腹肢发育相关基因的表达、功能及调控因子间的相互作用等方面进行简要的综述。
Background: Silk gland is a larval specific tissue of lepidopteran insects.Ecdysteroid is one of the two most important insect hormones playing a very important role in inducing molting and metamorpho
[目的]研究氟化物对家蚕Bombyx mori 肠道内留存产酶菌的影响，有助于了解家蚕耐氟和氟敏品种的耐氟力差异。[方法]分别给家蚕耐氟品种T6 和氟敏品种734 添食NaF 溶液浸泡后的新鲜桑叶，至5 龄第3 天取材。采用筛选培养基筛选产蛋白酶、纤维素酶、脂肪酶、淀粉酶的菌株，并结合16S rDNA 系统发育关系，对菌株进行 分类鉴定。

为了探讨氟化物对家蚕代谢机制的影响,以家蚕耐氟品种T6 和氟化物敏感品种734为研究材料,从5 龄起蚕开始分别添食经50,100,200,400 mg/kg NaF 溶液浸泡后的新鲜桑叶,检测家蚕血液和中肠中海藻糖含量的变化.结果表明,血液中,随着添氟浓度的增加,734 添氟组海藻糖含量约是对照组的0.89,0.95,0.65 和0.61 倍,T6 对照组的0.82,0.86,0.87 和0.89
