Life-Table of Uji Fly Exorista bombycis Louis on Pure Mysore Silkworm Race

The life-table of uji fly, Exorista bombycis L. was construction through 16 generation using fourth stage of Pure Mysore silkworm race as a host for depositing eggs with the different biotic characters like, mortality at every stage of its life cycle (eggs, maggots, post-parasitic maggots, puparia and adults) in the rearing room. Maximum percentage of mortality at puparia, adults, maggots, eggs and post-parasitic maggots stages was 36.04, 23.25, 17.62, 17.36 and 10.07 per cent, respectively. Similarly, the survivability rate varied at different stages, being minimum at pupal stage (63.96%) compared to adult (76.75%), maggot (82.38%), egg (82.64%) and post-parasitic maggot stages (89.94%). The number of individuals dying within the age and mortality factors are responsible for every stage of its life cycle have been discussed.
