Abstract: To study the different parameters of the Bombyx mori four host viz S-146, S-1635, V-1 and TR-10 and one alternate host plants under natural conditions highest percent mortality of 13.2 species recorded at early stage larvae on V-1. Generation survival fraction revealed that S-146 was most preferred host plant. Life table studies, viz. stage specific and survival of B. mori on the four species of mulberry plants (Morus alba) i.e, S-1635, S-146, V-1 and TR-10 under natural condition indicate that the insect preferred all the four hosts species but S-146 was favored, suitable food for the development and shows the lowest mortality of Bombyx mori.
