Abstract:	In glasshouse experiments, inoculation of soybean with Pratylenchus alleni or P. scribneri (20 000 nematodes/pot) significantly reduced shoot and root weights at 29 deg C (45 and 49% respectively for P. alleni and 23 and 47% for P. scribneri). At 34 deg C tolerance of plants to P. scribneri was reduced resulting in growth reduction; P. alleni did not affect growth at this temperature. Both species reproduced between 22 and 34 deg C, but population increase was least at 22 deg C. The optimum temperature for population development of P. alleni was 30 deg C; that for P. scribneri was between 30 and 34 deg C.
