The study of the chemical nature of the exudates, water permeability and other changes at the time of hatching from eggs as well as from freshly hatched larvae of two ecotypes of cereal cyst nematode, Heterodera avenae showed that water content of hatched and unhatched larvae was 70%. Uptake of water by eggs and larvae inside eggs seemed to have no role in hatching process, while glycoproteins were released in the hatching media.
