The nonfeeding preadult larvae of the plant-parasitic nematodes, Paratylenchus projectus and P. dianthus, survive in moist soil during long periods in the absence of host plants. In water, only small percentages molt to the adult stage. In root diffusates from some but not all plants, nearly all of them molt.
