Effect of short-term cold storage on mummy-stage survival in two parasites of the Russian wheat aphid

We measured the effect of storage for 0, 2, 4, 7 and 14 days at 10C on adult emergence from mummies in Aphelinus asychis (Walker) and Aphelinus albipodus (Hayat and Fatima) (Hymenoptera: Aphelinidae) stored in either waxed cardboard cartons or in gelatin capsules. For both species, no significant difference was observed in the proportion of adults emerged under either storage method. Adult emergence decreased significantly in both species when mummies were stored for 14 days compared to 0-7 days. No significant difference was observed in the size of adult A. albipodus parasites emerging from mummies stored for 14 days relative to those stored for shorter periods.
