Resumo
In a small pot, experiment Xiphinema index populations from Italy and U.S.A. reproduced on fig but not on Petunia hybrida, and only the U.S.A. population reproduced on tomato. Reproduction occurred at 22º and 29ºC, but virtually none at 15º or 36ºC and the U.S.A. population had a greater reproductive capacity than the Italian. The life cycle of the U.S.A. population was 55 days at 22º or 29ºC whereas that of the Italian was estimated as 62 days.
