title: Improved methods of hatching Heterodera schachtii larvae for screening chemicals.
abstract: The rate of hatching of Heterodera schachtii larvae was greatly increased by placing cysts in sieves enclosed by small disposable cups. An apparatus that permitted rapid storage of second-stage larvae at 10 C prolonged the viability of the larvae.
