蟲后物質
英文
queen substance-
The distribution of the brine shrimp hgcs varies greatly from the species studied till now. one hour after hatching, neither the dorsal - anterior area nor the other dorsal area remained positive immunoreactivity signal. and 2 hours after hatching, there was no typical hgcs in the body of the brine shrimp and the remained hatching enzymes may participate in digesting the left vitellin in the nauplius
鹵蟲hgc最初出現至孵化前1h時均為全身性分佈，從孵出到孵出后2h ，頭鹵蟲孵化酶的生物化學性質及孵化腺細胞的免疫組織化學研究部的孵化酶顆粒已經減少，而變為非全身性分佈，到孵出后sh ，孵化酶顆粒已基本消失殆盡。But this mosquito has an added gene for a substance that blocks the parasite ' s movement out of the insect ' s gut and into its saliva, keeping its next bite from being infectious
但加入了某種基因后，這種蚊子產生的一種物質能夠將瘧原蟲的活動范圍限制在蚊子的腸道，使它不能進入唾液中，這樣的蚊子在下一次咬人時就沒有了傳染能力。No trace of any newly expressed protein band was noticed in supernant as well as in the cells by sds - page, except the verification of the substitution of beta - galactosidase gene ( the lose of galactosidase protein band ), which is a selective marker of the wild - type virus. elisa test results suggested the expression of egf in cells, but not in culture supernant. the quantitative calculation suggested the expressed egf was about 6 - 7 u g ( as egf standard ) per flask ( 2 > < 106 cells ) in the cellular extract
將重組病毒rbmbacph - egf以10moi感染bmn細胞， 72小時后收集培養細胞和上清；培養上清和經超聲波處理的細胞樣品elisa檢測發現胞內樣品中存在能與egf抗體免疫反應的產物，粗略估計表達量約6 7 g 2 10 ~ 6個細胞（相當于egf標準品） ；重組病毒rbmbacph - egf穿刺接種5齡家蠶幼蟲，每隔24h收集蠶血淋巴，經elisa檢測發現第4天表達量最高，根據egf標準曲線計算蠶血淋巴的表達量約32 g ml ； elisa定性實驗還發現正常蠶血也存在與egf抗體間交叉反應的物質。1. physical changes of hemolymph of p. americanna after injection with m. anisopliae the ph value of hemolymph of p. americanna increased rapidly from ph6. 8 to ph 7. 0 and the number of hemocytes ( nh ) of p. americanna at all the developing stages became lower than the blank control ( bc ) after injection with 4 + 107 / ml fungal spores
1注射綠僵菌孢子后蜚蠊血淋巴物理性質的變化蜚蠊若蟲血淋巴ph值為ph6 . 8 ，注射4 10 ~ 7個/ ml濃度的綠僵菌孢子到蜚蠊體內后，蜚蠊血淋巴的ph值上升到ph7 . 2 。The hemolymph immune reaction of american cockroach to the entomopathogenic fungus, metarhizium anisopliae isolate cqma102, which is broadly used in locust control, was studied in the research. the results will enrich our knowledge about insect immune mechanism and the insecticidal mechanism of entomofungus. they will also be the fundamental work for insecticide development
本研究以重要的室內蜚蠊種類? ?美洲大蠊（ periplanetaamericana ）為實驗材料，採用蜚蠊的非致病菌? ?金龜子綠僵菌（ metarhiziumanisopliae ） cqma102菌株作為供試菌，較系統地研究了綠僵菌孢子進入蜚蠊體腔后（點滴和注射處理） ，蜚蠊血淋巴某些理化性質的改變、血淋巴的免疫反應以及蜚蠊的行為反應等，有助為研究昆蟲的抗病機理和生物殺蟲劑的殺蟲機理，同時也為生物殺蟲劑的開發提供了必要的基礎。3 antimicrobiol substance and protein in the hemolymph of nymphae induced by m. anisopliae no antimicrobiol substance was detected in the hemolymph of nymphae by different kinds of micropathogens after injection with m. anisopliae, which meant that the fungus could not induce p. americanna to produce antimicrobiol substance. injection of fungal spores caused the decline of protein concentration ( pc ) at the begaining, but after that the pc increased rapidly
3綠僵菌孢子對蜚蠊血淋巴中抗菌物質及蛋白質的誘導注射綠僵菌后的不同時期提取蜚蠊血淋巴，以多種不同類型的植物病原菌、昆蟲病原菌及腐生菌作為檢測菌，均未檢測出蜚蠊血淋巴中有抗菌物質存在，即綠僵菌不能誘導蜚蠊產生抗菌物質。3 chemical action : the stimulating action of metabolites products of metabolism, excretions and secretions from parasites, and chemical substances generated from dismembered dead parasites can cause many types of damage to the human body
3化學作用：寄生蟲的代謝產物分泌物排泄物和蟲體死亡后的分解物等化學物質的刺激作用，對人體可造成各種不同的危害：如溶組織阿米巴，分泌溶組織The application of nitrogen fertilizer affected positively and negatively the predation abilities both in laboratories and fields by its indirect and direct roles in the trophic relationship among host plants, herbivores and predators, the improvement of nutrients and the modification of allelochemicals in host plants
摘要施用氮肥后可以直接或間接地通過對植物害蟲天敵三者之間關系的干預、改變寄主植物內的營養成分和次生化學物質的含量等從正反兩個方面影響捕食性天敵的捕食能力。分享友人
