摘要：Factors influencing the adoption of Russian Varroa-Resistant honey bees were assessed using a double hurdle model. Results indicate factors associated with the adoption include sales over $1,000 of bee related products, residence in the delta states, internet use, and membership in the AHPA. Negatively associated factors are high percentage of income coming from beekeeping, and membership in the ABF. Intensity of adoption increased with frequent contact with the USDA, and decreased with greater colony size, sales and membership in the ABF.
