Abstract:

In small-scale field tests in which the dominant avirulent Great Plains biotype of Mayetiola destructor (Say) was released into a population of eastern soft wheat biotypes, the population of native flies was suppressed. An inundative release of 20:1 Great Plains biotype to native flies had the greatest impact after 2 releases. The native population was reduced from ca. 101,250/ha to less than 810/ha after the 4th release; the control population, meanwhile, increased to ca. 173,700/ha. The Great Plains flies were fully competitive with the native flies, an enhancement to the potential this method of control offers.
