Effect of low temperature storage of trichocards parasitised by Trichogramma chilonis (Ishii) and Trichogramma japonicum (Ashmead)

The present investigations were undertaken on laboratory studies of Trichogramma chilonis (Ishii) and Trichogramma japonicum (Ashmead) during the year 2013-2014 in the bio-control laboratory, Department of Agricultural Entomology, College of Agriculture, Dapoli (Maharashtra). Effect of low temperature storage at 150C temperature for varying period on egg cards parasitised by T. chilonis and T. japonicum, 4 day after parasitisation revealed that parasitised trichocards after 4 days of parasitisation can effectively stored up to 15 days without much effect on adult emergence.
