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. Key Words: Hatching apparatus, sugarbeet nematode, increased viability.
