Experiment was conducted to study the effect of temperature on longevity of Heterorhabditis indica under controlled laboratory conditions. The results showed the maximum survival rate of 77.29% at 200C after 90 days of incubation, followed by room temperature (25-280C) and 300C test temperature showing 61.30% and 54.60% survival rate after 90 days of incubation, respectively. At test temperatures 100C and 400C the survival rate was 0.0% and 0.33% after 20 days of incubation, indicating that themortality of IJs of H. indica occurred due to lethal low and lethal high temperature effects, respectively. The results indicated the optimum temperature for storage of H. indica was 200C.
