title = "Genetic differences between eastern and western populations of the alfalfa weevil",
abstract = "Allelic variation at five enzyme loci was investigated in eastern and western United States populations of the alfalfa weevil, Hypera postica. Significant differences in gene frequencies were observed between the eastern and western populations, some of these differences being correlated with geographic variables. The genetic data obtained strongly suggest that two genetically distinct populations of Hypera poslica exist in the United States and support the hypothesis of two different introductions of the alfalfa weevil into the United States, each introduction presumably from a different European origin.",
