Among the five different temperatures tested for storage of infective juveniles (Ijs). survival of Steinernema feltiae Filipjev and S. glaseri Steiner was higher at 7.5°C, while the survival of Heterorhabditis indica (Poinar, Karunakar and David) was higher at 10°C. All the three species of nematodes showed higher percentage of survival when stored at 250 IJs per ml compared to 500 and 1000 Us per ml. A negative correlation was observed between duration of storage and per cent survival in S. feltiae (r = -0.9831**). S. glaseri (r = -0.9847**) and H. indica (r = -0.9437**). Based on the results of the study, the best combination of temperature, population density and duration of storage for the entomopathogenic nematodes was 7.5°C, 250 IJs perml and 120 days, respectively for S. feltiae, 7.5°C, 250 IJs per ml and 90 days for S. glaseri and 10°C, 250 IJs per ml and 90 days for H. indica.Downloads
