Extract

There is a winter dormancy in the hatchability of some species of Heterodera. The dormancy varies in degrees with eelworm species, being slight in the case of beet eelworm and more pronounced in the case of potato-root eelworm and some other species. It is not wholly dependent on immediate environmental conditions but possibly is induced by previous conditions. The dormancy can be shortened by storing infested soil at certain temperatures, but the cessation of dormancy in spring is not necessarily associated with rise in soil temperature.
