Abstract. Growth room experiment was carried out to investigate the effect of different temperatures on the efficacy of the rhizobacterium Bacillus subtilis on the development of the root-knot nematode Meloidogyne arenaria. Potato plants (Solanum tuberosum L.) were inoculated with M. arenaria second-stage juveniles. At 7th, 14th and 21th days after nematode inoculation the rizosphere of the plants were treated with bacterial suspensions of the two local strains of B. subtilis (A1 and B1). The potato plants were grown in growth room at 16±1, 20±1, 24±1, 28±1 and 32±1ºC. The rate of M. arenaria development in potato roots treated with B. subtilis (strains A1 and B1) was lower than that in the untreated plant roots. The highest efficacy of the bacterium on the development of M. arenaria was observed at 24-32ºC.
