A storage protein gene, CsSP2, was eloned and sequenced from the rice stem borer, Chilo st4npi'essalis. Analysis of the cDNA scquence revealed an open reading frame of2,118bp in length which encodcs an arylphorin-like protein with a calculated molccular weight of 83.7 kDa. The cxpression level of CsSP2 was higher in non-diapausing Iarvae than in diapausing larvae at 20"C. When diapausing larvae...
