摘要: The entomopathogenic nematodes Heterorhabditis bacteriophora, Steinernema carpocapsae, glaseri, and feltiae were exposed to freezing while inside their hosts. Survival was assessed by observing live dead cadavers counting the infective juveniles (IJs) that emerged after freezing. We (1) measured effects of 24h at different times throughout course an infection, (2) determined duration could survive, (3) species differences in survival. Highest stage-specific survival IJs for S. adults H. bacteriophora. When frozen two or three days few from them. Freezing between five seven infection had no negative effect on IJ production. No decrease production bacteriophora also showed improved versus outside host when
