Abstract


In a laboratory study at 18"-22 °C, a Slovakian population of Xiphinema vuittenezi developed from egg to adult in six months, equivalent to 3360 day degrees above a minimum daily threshold of 5 °C. Female longevity on Vitis vinifera was slightly more than 24 months. It is estimated that between month 3 and month 18 individual female has a reproductive capacity of 152 to 160 progeny. Its life cycle will then complete in one year or longer, under central Europe natural conditions.
