How is wheat yellow mosaic virus transmitted to plants?

• A. Insects
• B. Fungi
• C. Nematodes
• D. Wind

Answer: (A)

Wheat yellow mosaic virus is primarily transmitted to plants by insects, specifically aphids. These small sap-sucking insects play a crucial role in the virus's spread, as they can pick up the virus from an infected plant and then move to a healthy plant, transmitting the virus in the process. This method of transmission is known as a vector-mediated transmission. In contrast, fungi, nematodes, and wind are not the primary mechanisms for the transmission of this specific virus. Fungal pathogens typically involve a different group of diseases associated with field crops, while nematodes are parasitic worms that feed on roots or other plant parts, and wind generally aids in the dispersal of pollen or spores rather than viruses like the wheat yellow mosaic virus. Understanding the primary role of insects in the transmission of this virus is key to effective pest management strategies.
