摘　　要：Growth room and glasshouse experiment was conducted to investigate the effect of constant and fluctuating tem- peratures on the development of Pasteuria penetrans a hyperparasite of root-knot nematodes. Tomato plants (Lycopersicon es- culentum Mill) were inoculated with Meloidogyne javanica second-stage juveniles attached with endospores of P. penetrans and were grown in growth room at 26?29 °C and in glasshouse at 20?32 °C. The tomato plants were sampled from the growth room after 600 degree-days based on 17 °C/d, accumulating each day above a base temperature of 10 °C and from the glasshouse after 36 calendar days. Temperature affected the development of P. penetrans directly. The rate of development at constant temperature in growth room was faster than that in the glasshouse at fluctuating temperatures.Growth room and glasshouse experiment was conducted to investigate the effect of constant and fluctuating tem- peratures on the development of Pasteuria penetrans a hyperparasite of root-knot nematodes.
