Methods of the long-term storage and utilization of eggs of Sitotroga cerealella (Oliver) for production of Trichogramma pretiosum Riley



Methods of the long-term storage and utilization of eggs of Sitotroga cerealella (Oliver) for production of Trichogramma pretiosum Riley



Colloques de l' INRA (43): 373-377



Eggs of the gelechiid Sitotroga cerealella which were placed in sealed vials, held at 10 degrees C for 24 h, and then placed in liquid nitrogen for 21 days, were acceptable hosts for Trichogramma pretiosum. Treated eggs produced parasitoid pupae at about half (43.0%) the rate of fresh eggs (82.1%).
