Trichogramma platneri Nagarkatti (Hymenoptera: Trichogrammatidae) was recently introduced into Israel to improve the control of two lepidopterous pests, Boarmia selenaria (Schiffermiiller) and Cryptoblabes gnidiella (Millière). Laboratory tests showed that T. platneri attacks the eggs of both species. A method of freezing the eggs of the host, Ephestia cautella (Walker), at -20°C and gradual defrosting, used in the large laboratory breedings of the parasites, is described briefly. In laboratory tests 68.5% of the frozen E. cautella eggs, after 2 months of storage, were parasitized, compared with 70.3% of the fresh eggs. © 1985, Springer Science + Business Media B.V..
