Abstract


In a laboratory study at 24 °C a population of Xiphinema diversicaudatum from Slovakia developed from egg to adult in about 12 wk, on Lolium perenne. Longevity of females was about 56 wk and reproductive span 36 wk. Between week 12 and week 36 each female produced a mean total of 33 progeny. It is estimated that during a period of 48 wk and individual female has a reproductive capacity of 60-70 progeny. Egg laying rate is the ration between progeny recovered and mean number of eggs observed in the uteri in the previous period of observation.
