Abstract
In a laboratory study, individual female Trichodorus sparsus from a northern Italy population had a longevity of c 22 wk on S. Lucie cherry plant. The reproductive span of the nematode was only c 16 wk and estimated mean total reproductive capacity was 215-225. It was calculated that development from egg to adult took 40-42 days. This species appears to have adopted a "K" survival strategy as far all tylenchs, longidorids and trichodorids. However, the relationship between cumulative total progeny production and observation times (weeks) far this species fits closely (r = 0.971) a logarithmic curve.
