Abstract

Proteins in whole bodies of two-spotted spider mites, Tetranychus urticae, were compared between non-diapause and diapause conditions using one- and two-dimensional electrophoresis. At one-dimensional analysis diapausing mites synthesized several unique proteins that are higher in their quantity than non-diapausing ones. Overall protein numbers in twodimensional gel show that diapause mites expressed fewer proteins than non-diapausing ones. However, 25 proteins that have higher quantity in diapause were selected at the range of low molecular weight (5-20 kDa). Among them 13 proteins were only present in diapause mites. Our results thus indicate some proteins uniquelyexpressed during diapause and may have specific roles during long overwintering period.
