摘要: ABSTRACTInduction of anhydrobiosis and storage stability entomopathogenic nematodes are influenced by moisture availability. Decreasing content in diatomaceous earth (DE) pellets containing the Steinernema glaseri NJ-43 strain its effect on survival time infectivity nematode were determined. Pelletisation was performed a vortex mixer, using DE Celite® 209 as desiccant material. Pellets stored at room temperature (23 ± 2°C) high relative humidity (96–100%). Nematode against last instar greater wax moth, Galleria mellonella, tested daily. Initial average equilibrium 66.7% 13.6%, respectively, infective juveniles mean 8.8 days. A transfer model based diffusion evaporation evaluated to predict fluctuations within pellets. We concluded that 84% variation S. G. mellonella larvae explained survi...
