Abstract:

A permanent nursery for the assessment of resistance of strains of wheat, Triticum aestivum L., to the wheat stem sawfly, Cephus cinctus Norton, was started in 1959 and successfully established by 1966. Sawflies for the infestation were obtained from naturally infested fields and were transferred to the nursery in 1 of 3 ways: (1) Stubs containing larvae were transplanted to the nursery in the fall (2) Infested Hubs were dug in the fall, held in a constant temperature room at l0 through the winter, and transferred to the nursery in the spring. (3) Adult sawflies were captured with sweep nets in June and immediately transferred to the nursery. The first method was most practical. The second was dependent on the availability of temperature-controlled rooms and more time and effort were required, but mortality was kept to a minimum, because the larvae were not exposed to adverse elements. The third method was a good supplementary method. The major problem encountered was drought.
