The survival rate and number of parasitized host of Encarsia formosa Gahan and Eretmocerus eremicus Rose were observed at low temperature conditions (6, 8, 10 and 12 ± 1oC, RH 70 ± 10%, in dark condition. Mummy of Encarsia formosa was stored at 12oC, for 70% of the mummies survived for 10 days. After 6-days storage at 12oC, number of parasitized host of the parasitoids was decreased to 35.9 (67.6%, compared to control). Mummy of Eretmocerus eremicus was stored at 12oC, and 70% of the mummies survived for 14 days. After 6-days storage at 12oC, number of parasitized host was decreased to 31.6 (83.6%, compared to control). Our results suggest that 12oC was most suitable temperature for storage of Encarsia formosa and Eretmocerus eremicus.
