Bean pod mottle virus transmission is associated with which soybean pest?

Bean pod mottle virus transmission is associated with which soybean pest?

• A. Blister beetles
• B. Bean leaf beetles
• C. Soybean aphids
• D. Stink bugs

Answer: (B)

Bean pod mottle virus is spread by the beetles that feed on soybeans, with the bean leaf beetle being the primary vector. When these beetles feed on infected plants, they acquire the virus and can then inoculate healthy plants during subsequent feeding, especially during pod development. Other pests listed may cause damage through feeding, but they do not transmit BPMV, so they are not the vectors for this virus. Knowing this helps explain why managing bean leaf beetle populations is a key part of reducing BPMV spread and its impact on yield.
