Effects of Temperature on the Survival of Meloidogyne inicognita
摘要
Abstract
The effect of temperature on the survival of Meloidogyne inicognita is studied with the method of laboratory and field experiments. The result shows that the optimum temperature of the Meloidogyne inicognita. egg hatching is 28 degrees, and 13℃ is not suitable for hatching oocysts, but there is a small amount of oocysts hatched J2 (second stage of juveniles), 2 ℃ oocysts couldn't hatch. The longest time for J2 survival is 30 days, which can survive at 13 ℃; the J2 survival time is shortened at 13 ℃above and below, -12 C below of the low temperature can not survive. The field survey found that the temperature had a significant effect on the survival of the Meloidogyne inicognita. The number of soil Meloidogyne inicognita. decreased with the decrease of atmospheric temperature. In addition, the large number of Meloidogyne inicognita is occurred in soil 0~5 cm of late December, and 5~10 cm of mid-November, and 10 ~ 15 cm After 12 months. The number of soil Meloidogyne inicognita. is decreased; the number of Meloidogyne inicognita. close to 0 in mid February next year.关键词
