To elucidate the roles of fatty acyl chains in phosphoglycerides during egg diapause process of the silkworm Bombyx mori, fatty acids of phosphatidylcholine (PC) and phosphatidylethanolamine (PE) were analyzed by gas-liquid chromatography. Diapause-associated changes occurred in the proportion of oleic acid (C_<18 : 1>) and linolenic acid (C_<18 : 3>) tails in total fatty acids of PC and PE. In diapause initiation, the levels of C_<18 : 1> increased (about 35-40%) and that of C_<18 : 3> decreased (about 20%). These ratios remained constant during diapause maintenance. However, transfer of diapause eggs from 25℃ to 5℃ resulted in decline in C_<18 : 1> and rise in C_<18 : 3> of both PC and PE. Both levels shifted 28-30% in diapause termination. These results suggest that fatty acyl chains in PC and PE are modulated during the diapause process and that cold exposure induces the unsaturation with C_<18 : 3> of phosphoglycerides.
