In 1986 researchers in the private and public sectors in the United States and several foreign countries produced ca. 50 million European corn borer, Ostrinia nubilalis Hubner, egg masses (ca. 1.5 billion eggs) for host plant resistance research. Nearly five times as many egg masses were produced in 1986 with the meridic diet technique as were produced by the United States Department of Agriculture (10 million masses) over a 33-year period (1932-1965); during those years, moths were collected from large emergence cages that had been filled with infested cornstalks, Zea mays L., the previous fall. Methods and equipment for preparing diet, infestation, rearing, and egg collection are described.
