Abstract

SEMINAR: NEMATODE SAMPLING AND PREDICTION BY B. BOAG, R. NEILSON and D. J. F.

The importance of identifying the objectives of the sampling programme and species of nematode to be studied is emphasised. The development of optimum sampling patterns and the evolution and application of different mathematical formulae to describe the horizontal aggregated distribution of nematodes are discussed.
