Testing Hypotheses of Phylogeny of Heteroderidae,requently described and genera are variously grouped into subfamilies and other taxa by a number of authors. Luc et al. (1978) pointed out “heterogenity and inconsistencies” within subfamilies and proposed abolishing existing subfamilies. They suggested that arrangement of genera into meaningful (i.

The gap between theory and field application has yet to be bridged, although several recent developments in research into the hatching mechanisms of cyst nematodes indicate that measures which influence nemat

Effects of Nematode Attack on the Growth and Yield of Crop Plants, of the damage was related to the degree of infestation of the soil, the exact nature of this relation remained vague in the minds of most investigators. Even so efforts to advise farmers on crop rotation against cyst nematode attack had already started in the first half of this century, most probab
