  • Two storage proteins, storage protein-1 (SPl) and storage protein -2 (SP2) were found in hemolymph and fat body during the development of Lymantria dispar L. SP1 has a molecular weight of 440, 000 and consists of six identical subunits (MW = 72, 000). The pI value of SP1 was 6.2. SP1 shows a similar high concentration during the late larval stage in both male and female. However, SP1 represents a quite different pattern during pupal stage between male and female. SP1 gradually decreases in male but increases in female. SP1 is immunologically identical to yolk protein. Also, SP1 of L. dispar shows immunologically partial reactions with storage proteins of Hyphantria cunea and Galleria mellonella.
