摘要

The mean tolerated a_w value (MW₅₀) ranged from 0.90 to 0.95 for non-adapted and 0.67 to 0.99 for adapted nematode populations. For selective breeding, only the 10% most tolerant individuals would be used. The lowest a_w value tolerated by 10% of a population (MW₁₀) ranged from of 0.845 to 0.932 for non-adapted nematode populations and 0.603 to 0.950 for adapted nematode populations. Adaptation significantly increased the desiccation tolerance and a weak correlation was recorded for tolerance with and without adaptations. The most tolerant nematode strains will form the basis for the foundation of a parental stock produced by cross-breeding and following genetic selection for enhanced tolerance. Thus, this investigation is another milestone on the road to domestication of H. bacteriophora for commercial use in sustainable pest management.
