The impact of cold storage durations on (Westwood) (Hymenoptera: Trichogrammatidae) during their pupal stage.

This experimental study was done at the Biological Control Laboratory, Sakha Agricultural Research Station, Sakha, Kafrelsheikh, Egypt. We aimed to estimate the impact of different cold (10 °C) storage durations [0 (non-cold-stored parasitized eggs), 3, 6, 9, 12, 15, 18, 21, 24, 27, and 30 days], on (Westwood) (Hymenoptera: Trichogrammatidae) during the pupal stage using the eggs of after exposing to . The emergence percentage of non-cold-stored eggs of was higher than all cold-stored durations.
