摘要：Pathogenic infection in tasar silkworm,Antheraea mylitta Drury.is common and there is a breed specific response regarding tolerance.Observations reveal the possibility of differential response by haemocytes to microbial infection in different breeds.Hence,the susceptibility of three eco-races of tasar silkworm viz.Daba,Sarihan and Raily to Antheraea mylitta Cytoplasmic Polyhedrosis Virus (AmCPV) infection and difference in total haemocyte counts were tested.The survival of Daba,Sarihan and Raily eco-races was significantly different (p < 0.05) when challenged with the same concentration (1 x 105 polyhedra/ml) of AmCPV.Daba eco-race was more tolerant to the AmCPV infection having higher survival (66.7%) and LC50 values (1000893.1796 polyhedra/ml) of AmCPV followed by Sarihan eco-race (50.7% survival and LC50 value of AmCPV 187203.6168 polyhedra/ml.) and Raily eco-race (25.3% survival and LC50 value of AmCPV 5176.37 polyhedra/ml.).Difference in total haemocyte count i.e.higher in tolerant (Daba) and lower in susceptible (Raily) eco-race may be in response to difference to their susceptibility to AmCPV infection.
