Water soluble proteins of six nematode species of Heteroderidae (Heterodera glycines, H. oryzae, Meloidogyne hapla, M. incognita, M. mali, Meloidogyne (=Hypsoperine) sp.) were investigated by the disc electrophoresis technique. They showed distinct and characteristic protein patterns. However, their protein patterns varied according to their host plant species and the developmental stages of the nematodes. A common tendency found in H. glycines, M. hapla, and M. incognita was intensive stainability of faster-moving protein bands as the nematodes became senescent or when they grew on the host plants the growth of which was retarded. This was also observed in the root-knot nematodes which were treated with D-D fumigation. Zymograms of esterase, acid phosphatase, and lactate dehydrogenase isozymes seemed to vary more greatly with the developmental stages of the nematodes than with the difference in the growing conditions of the host plants. The faster-moving bands of lactate dehydrogenase isozymes in M. incognita became more intensive as the females became senescent.
