EASTERN AND WESTERN ALFALFA WEEVILS, HYPERA POSTICA (GYLLENHAL): DISTRIBUTION IN NEBRASKA, CHROMOSOME COMPARISONS, AND EFFECTS OF ANTIBIOTICS ON CROSS INCOMPATIBILITY.
Abstract
With its accidental introduction into the United States from Europe or Asia, the alfalfa weevil, Hypera postica (Gyllenhal), has been the most important pest of alfalfa. During recent years the weevil has cost American farmers about $60 million a year (Kehr and Manglitz 1971). Originally detected in Utah in 1904 (Titus 1910) the weevil slowly spread throughout the western states. Many western states imposed quarantines on the movement of alfalfa hay and other alfalfa products to limit the spread of the weevil. Although quarantines may have slowed the spread they did not contain the weevil and it was recovered in northwestern Nebraska in 1928 (Marlatt 1928).By 1970 it occurred in Buffalo and Kearney counties in central Nebraska (Keith et al. 1974).
