Technical Abstract: Research has continued to examine genetic differentiation among economically important Diabrotica species. The overall goals include gathering requisite fundamental molecular genetic knowledge about Diabrotica sp., to survey population diversity and help clarify the biosystematics, and to develop molecular marker systems for identifying species/strains of Diabrotica and emerging phenotypes. The two areas of emphasis this year have been: (1) Geographic genetic variation in the northern corn rootworm; (2) Improve species specific markers for larval identification. DNA segments from mitochondrial genome have been used in both cases.
