特化蟲體
英文
kenozooid-
After molting three times, the zoea enter the mysis stage during which they begin to look more like adult shrimp and swim in a characteristic fashion with head and tail pointed downwards at right angles and occasionally performing a sudden retrograde jumping action. this is known as the inversion state, the fry being suspended upside - down in the upper middle region of the pond water. this is, therefore, also called the " inverted suspension phase "
眼幼蟲脫第三次即進入糠蝦期幼蟲期mysis stage ，此期之體形已略成蝦之狀態，且具特有之游泳姿態，即頭部及尾部均向下，成一直角彎曲而時作向後跳躍游動，又因成倒立狀態，懸浮於水中的中上層，又叫倒吊期，此期幼蟲對外界的環境因素，如水溫鹽分等變化，比前兩期來得更具適應力，主要餌料為豐年蝦brine shrimp的幼蟲，但其他大小略同的動物性浮游生物，如橈腳類copepoda輪蟲類rotifera均可。The availability for classification of hemiptera insects by using the esterase isoenzynes, microorganisms and digestive enzymes characters has been studied. the results are as follows. 1. there were differences in the electrophoretic pattern of the bugs

本研究利用線蟲誘導下owvt - 1菌株液體發酵，通過粗分級分離、離子交換層析和凝膠過濾層析分離提純了一個分子量為31kda的絲氨酸蛋白酶，生物學測定表明其對大豆胞囊線蟲二齡幼蟲具有致死作用，同時測定了該酶理化特性，酶活力在75附近酶活力最高，隨著ph的增加酶的穩定性升高，與膽堿酯酶具有相似的ph曲線，對特異性底物aape （ suc - ala - ala - pro - glu - pna ）具有作用， ssi和ci - 2抑制該酶的活性。3. the effect of sporulation - independent promotor on toxicity of natural strain in order to study the effect of sporulation - independent promotor ( p3a ), p3a was spliced with the cry1c gene, then inserted into the shuttle vector pht304, and then recombinated plasmid pbmb827 was obtained. after transferring pbmb827 into strain ybt - 1520, it was surprising that the transformants had almost no potency against all lepidopteran larvae tested
3非依賴芽胞形成icp的cry3a啟動子（ p _ （ 3a ） ）對野生菌株特性的影響帶p _ （ 3a ）和cry1c基因的重組質粒pbmb827轉入ybt - 1520 ，轉化子對所測昆蟲的毒力下降非常明顯，芽胞和晶體也很難脫落。In this paper two - generation reproduction toxicity of fenvalerate, a - cypermethrin, chlorpyrifos, and triazophos was tested in a 21d period with water flea, daphnia magna, . the toxicity indicator included longevity, body length, days to first brood, days to first pregnancy, number of youth per female, intrinsic rate of natural increase ( r ), and number of broods per female. accordingly, the dose - response relations and relations between the chronic responses and enzyme levels were investigated
為了確定水蚤體內生化指標與慢性毒害效應之間的關系，特別是在低濃度暴露狀態下生化指標改變的生物學意義，以便能更準確預測早期農藥對水蚤種群的潛在危害，本文以浙江省常用殺蟲劑氰戊菊酯、高效氯氰菊酯、三唑磷和毒死蜱進行了大型蚤（ d . magna ）的急性和慢性毒性試驗（包括子代水蚤的恢復試驗） 。After the recombinant plasmid pcdna3. 1 / ts87 was identified by digestion of hindlll and bamh i, it transformed into cos7 by lipofectamine. expression product was identified by immunohistochemical method, sds - page and western - blot. the immunocytochemistry result has shown that specific brown - staining grains were found in the cytoplasm of cells transformed by recombinant plasmid versus not seen in cells transformed by pcdna3. 1 or normal cells ; the sds - page result has revealed that a band about 3 8kb was found in cell lysis transformed by recombinant plasmid versus not in cells transformed by pcdnas. l or normal cells ; the western - blot result has showed that only the band about 38kd was recognized by sera from rabbit infected by t. s artificially and sera from rabbit immunized with soluble antigen of t. s and with protein expressed by ts87 gene and by a monoclonal antibody of t. s
