Abstract

The aim of this work was to assess the influence of different osmolyte concentrations on the viability and dormancy of free living Acrobelus nematode. A high-temperature (50°C) assay was done to check dormancy and viability. An extreme decrease in viability was noted when juveniles were exposed to high-temperature assay whereas non-desiccated juveniles died within short exposure to high temperature. Using the high-temperature assay, the mortality of desiccated nematodes was slow representing an improved capability to tolerate high-temperature conditions. At high osmolyte concentration (60%) maximum dormancy was observed. Variable recovery periods were noted when nematodes were exposed to two different temperatures. Low glycerol concentration at low temperature results in less recovery time.

Keywords: Dormancy, nematodes, osmolyte, recovery time, temperature
