These prawns are ideal animals tostudy the histopathological impairments caused by the effect of heavy metals prominent in riverGomti. The test animals were exposed to LC50value (0.15 mg/l and 0.16 mg/l respectively)at acuteexposure for 24, 48,72 and 96h and at subacute exposure25% of 96hr LC50 values of CdCl2 for malesand females (0.0375mg/l & 0.04 mg/l) respectively for 10, 20 and 30 day exposure. Thehistopathological changes were studied in both the sexes in the animals.Marked histopathologicalchanges were noticed in hepatopancreas of M.dayanum after cadmium chloride exposure. At 96 hacute exposure, hepatopancreas showed vacuolization in epithelial cells, necrosis in tunica propria,increased number of migratory cells, granuloma in intertubular connective tissue alongwithkaryorrhexis and karyolysis in cells. Necrotic and degenerative changes in hepatopancreaticepithelium, which were mainly, noticed in R and B cells. Loss of histological architecture along withthe heavy influx of haemocytes was recorded at this stage. After sub-acute exposure large vacuoles,particularly R and B cells were observed along with hypertrophy, necrosis and degenerative changesat most of the places in hepatopancreatic epithelium. Karyorrhexis and pyknosis were common.Increased number of migratory cells in intertubular spaces was a peculiar feature at this stage. Almostcomplete loss of the architecture of hepatopancreas was noticed and about 90 % of thehepatopancreatic tubules were found non–fuctional. The histopathological alteration in males wasmore pronounced than in females, both at acute and sub-acute exposure.","PeriodicalId":443629,"journal":{"name":"THE SCIENTIFIC TEMPER","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130893644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is generally grown inthe latitude range of 20°N to 25°N in Eastern India, especially, in parts of West Bengal, Jharkhand,Orissa, Chhattisgarh and Andhra Pradesh. The pupae of this ecorace remain in facultative pupaldiapause state for five to six months (January-June). During this long period of diapause losses occurdue to un-seasonal and unsynchronised emergence of male and female moths which is estimated tothe tune of 25-30% leading to reduction of seed production in grainages. The losses become moreprevalent when dry conditions prevail soon after pre-monsoonal showers. This can be avoided byconsigning the pupae of diapause termination state to low temperature. In the present study, thespecific age of diapause termination state has been worked out on the basis of the presence ofhaemolymph biochemical constituents like glycerol, trehalose, glycogen, quantitative total proteinsand free amino acids and protein profile comparing them with non-diapausing pupae harvestedduring first and second crop. Among diapausing pupae, the trehalose concentration always remainedat its low level during diapause and an increase in concentration was observed at the fag end ofdiapause when pupae attained the age of 145 to 150 days. Contrary to this, the level of glycerol andglycogen was always higher through out the diapause period and a down surge in the concentrationwas noticed when pupae were 145 to 150 days old. The level of protein was higher in nondiapausinggeneration. However, the level of protein and amino acids showed a fluctuating trendthrough out diapause development. The haemolymph protein profile of the diapausing pupae showedthe presence of a diapause specific protein band of 16kD which remained in its full intensity till thepupae attained the age of 145-150 days, thereafter, its intensity went down and protein profile ofdiapausing pupae looked similar to non-diapausing pupae. Therefore, it is confirmed that the diapausetermination state in Daba pupae occurs when pupae become 145-150 days old. The diapausingpupae of this age can be further exploited by working out low temperature treatment schedule toavoid losses in grainages","PeriodicalId":443629,"journal":{"name":"THE SCIENTIFIC TEMPER","volume":"8 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126004760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
