Abstract
The location of stem eelworm in lucerne plants was irregular, most eelworms being at the apical growing points or at the base of the plant. Eelworms were carried up passively as the plant grew. They were found in flower debris, i.e. in parts of pods, petals, etc., associated with seed samples but not in the seeds themselves. Increased humidity reduced viability of three races of stem eelworm, the lucerne race having the least resistance to high humidity. More than five eelworms scattered at random on the surface of the soil were required to start an infestation. Parthenogenesis did not seem to occur.
