The result shows that sperm ultrastructure , spermatogenesis , oogenesis and mature oocyte structure all have the characteristics unique to palaemon modestus . therefore , my researches ca n ' t only enrich the contents of reproductive biology in crustacean but also provide basic references for pond culture in palaemon modestus 結果顯示：秀麗白蝦精子結構、精子發生過程、卵子發生過程、成熟卵結構均有種的特屬性，從而本研究不僅可以豐富甲殼動物生殖生物學內容，同時也可為秀麗白蝦人工養殖提供基礎資料。
In this paper , the ovarian development , oogenesis , vitellogenin molecular characteristic , vitellogenin synthesis and uptake , and vitellin degradation in nasonia vitripennis ( hymenoptera : pteromalidae ) , are studied . the detailed results are shown as follows : 83 % of ovaries were found to be composed of eight ovarioles with four on each side and 17 % of ones to be composed of six ovarioles with three on each side . ovarioles appeared on the 10th day after parasitization , which were transpearant and had no egg chambers 為此，本論文就蠅類蛹期外寄生蜂? ?麗蠅蛹集金小蜂nasoniavitripennis (膜翅目：金小蜂科) ，卵巢發育、卵子發生，卵黃蛋白的分子特性，及卵黃原蛋白的合成、卵巢對卵黃原蛋白的攝取及卵子內卵黃磷蛋白的降解動態作了研究，結果如下：麗蠅蛹集金小蜂卵巢83由4對卵巢管組成， 17由3對卵巢管組成。
However , kit protein doesn “ t exist in oogenesis after birth . there are also c - myc positive protein granules in the spermatomeres from metaphase i to telophase ii , in the spermatozoa and in the secretory cells of the spermatheca . c - myc protein expresses not in the normal follicles , but in the follicular cells of the apoptotic ones Myc在處于減數分裂的中期至末期的精母細胞的細胞質或細胞核內呈陽性表達，在減數分裂后形成的精細胞和受精囊囊壁的上皮細胞的細胞質內也有陽性表達：但在出生后的卵子正常發生過程中無陽性表達，然而在凋亡卵泡的濾泡細胞的細胞質內有陽性表達。
Studies on spermatogenesis and oogenesis in palaemon modestus jiang ye - qin ( chemistry department , huzhou teachers coliege , huzhou 313000 ) palaemon modestus belongs to genus palaemon , family palaemonidae , caridea , natantia , decapoda , class crustacean . lt is a kind of freshwater prawn across china and especially abounds in the taihu lake which is regarded as one of the “ three delicacies “ of the taiha lake . as for the researches on palaemon modestus , v / e can only refer to spermatogenesis of freshwater shrimp exopalaemon modestus ^ ruang hai - xia et al , 2001 ) , studies on reproductive biology of exopalaemon modestus l . the structure and development of the male reproductive system ( huang hai - xia et al , 1999 ) and studies on freshwater prawn in the taihu lake ( yan sheng - liang , 1999 ) . on the bases of their researches and with the help of tem , i have made further researches on sperm ultrastructure , spermatogenesis , oogenesis and mature oocyte ultrastructure in palaemon modestus 秀麗白蝦palaemonmodestus屬甲殼綱crustacea十足目decapoda游泳亞目natantia真蝦部caridae長臂蝦科palaemonidae長臂蝦屬palaemon ，是我國南北均產的淡水蝦，其中太湖產量尤其大，與太湖銀魚、鱭魚并稱“太湖三寶” 。有關秀麗白蝦的研究僅見秀麗白蝦雄性生殖系統的研究(黃海霞等， 1999 ) 、秀麗白蝦精子發生的研究(黃海霞等， 2001 ) 。本人在前人工作的基礎上，利用透射電鏡技術( tem )進一步研究了秀麗白蝦精子的形態、結構及精子的發生過程，同時還研究了秀麗白蝦卵的發育過程，從卵原細胞到卵黃發生前的卵母細胞、卵黃發生的卵母細胞及成熟卵細胞，各期卵細胞的形態結構特點及各部分結構的變化情況。
Oogenesis was described briefly and the ways of the formation of yolk granules were explored . at first , eight stages in the oogenesis of the acrida chinensis were distinguished and described respectively , basing on the changes of the oocyte ' s size , chromosomal changes in the nucleus of the oocyte , vitellogenesis and the size of the follicle cells 在基礎理論方面，本研究首先在光鏡水平對中華蚱蜢卵子發生進行了階段劃分；并以此為依據，用組織化學方法對卵子發生中卵母細胞與濾泡細胞遺傳物質的變化及作用，組成卵黃的生物大分子物質的生成及變化進行了初步研究。
Secondly , the trends of dna and rna in the oocytes and follicle cells were displayed by histochemical method during oogenesis , which indicated that rna were synthesized at stage of the vitellogenic oocytes . but the quantity of dna was n ' t change 并根據這八個階段對卵子發生進行了組織化學的初步研究，結果表明，在卵子發生過程中，卵母細胞遺傳物質dna的總量相對保持不變，保證了遺傳信息的。
Ultrastructural features of oogenesis of the acrida chinensis were observed under tem . genesis of yolk granule and transformation of cell organelle in the oocytes of the acrida chinensis were investigated 總地來說，卵黃物質是由卵母細胞、濾泡細胞及脂肪體共同生成的；在以后卵的孵化及胚胎發育中起重要作用
S . oogenesis oogenesis can be devided into four stages : oogonia , provitellogenic oocytes , vitellogenic oocytes and mature egg . the chromatin in oogonia nucleus is in the shape of electron - densed granules 卵子發生卵子發生可分為卵原細胞、卵黃發生前的卵母細胞、卵黃發生的卵母細胞、成熟卵細胞四個階段。
The follicle cells taked part in the synthesis of yolk precursor , and the yolk precursor were transported into oocyte by pinocytosis and fusion . after follicle cells secreting egg shells , oogenesis completed 在幫助卵母細胞沉積完卵黃后，濾泡細胞還分泌卵殼蛋白，形成卵殼之后退化消失
In the oogenesis of the acrida chinensis , patency played a very important role in the process of fertilization 在外源性卵黃進入卵母細胞的過程中，濾泡開放現象起著重要作用。
