Edamame, Glycine max (L.) Merrill, consumption continues to rise in the United States. Improved understanding of production threats, including insect pests, could facilitate increasing production of edamame in the north-central United States. Two years of complimentary field and laboratory experiments were performed to assess insect pest populations on commercially available edamame varieties. Fourteen varieties of edamame and four grain-type soybean varieties were tested in the laboratory with soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), and subsets of these varieties were tested in the field with naturally occurring insect populations. In the laboratory, mean aphid densities on the edamame varieties Agate and Chiba Green did not differ from the aphid-resistant grain-type soybean. Among edamame, aphid densities on Agate, Chiba Green, and Kuroshinju were significantly lower than on Hokkaido Black. In both years of the field experiment, aphid densities were significantly lower on the aphid-resistant grain-type compared to all others varieties. In 2016, aphid populations on edamame varieties did not differ from the aphid-susceptible grain-types. However, in 2017 with greater aphid exposure, differences were seen among edamame varieties, and between edamame and aphid-susceptible grain-types. In both years, potato leafhopper, Empoasca fabae (Harris) (Hemiptera: Cicadellidae), densities tended to be higher on edamame varieties compared to grain-types, and varied significantly among edamame varieties. In a laboratory study, differences were seen among varieties in mean density of trichomes, with grain-types generally having more trichomes than edamame. Results of this research will provide a foundation for development of production recommendations for edamame in the north-central United States.
