Can Aphids Cause Blueberry Scorch?

Aphids are crucial vectors in the transmission of Blueberry Scorch Virus (BlScV), a harmful disease impacting blueberry and cranberry crops. These pests possess piercing-sucking mouthparts that damage plants by extracting their juices, leading to symptoms such as curled or crinkled leaves and hardened, distorted flower buds. Commonly found on stems, the undersides of leaves, and flower buds, aphids often form dense colonies on young shoots, where they produce large amounts of sticky honeydew.

BlScV is primarily transmitted by aphid species like Illinoia pepperi and Ericaphis fimbriata. These aphids spread the virus in a non-persistent manner, meaning transmission occurs quickly during feeding but does not require the aphid to retain the virus long-term. Studies show that a group of 25 aphids can transmit BlScV 10-15% of the time. Additionally, the virus can propagate through infected planting stock, facilitating its spread within and between fields.

The impact of BlScV on infected plants is severe, causing blossom and leaf blighting, complete flower blight, twig blight of young shoots, and significant yield reductions. Infected plants do not recover and continue to display symptoms annually, necessitating their removal to control the disease's spread. BlScV was first identified in British Columbia in 2000 and has since become widespread across all major blueberry-growing regions in the province. Managing aphid populations is critical in commercial blueberry farms, where only very low aphid levels are tolerated to minimize the risk of virus transmission.

BlScV transmission primarily occurs from spring through late summer when aphid populations are active. Preventive measures include controlling aphid populations and using virus-free planting material. Currently, BlScV and its aphid vectors are not reported in regions like Australia, underscoring the importance of biosecurity measures to protect susceptible blueberry industries from potential outbreaks. Effective management is essential to prevent severe yield losses and maintain healthy blueberry and cranberry crops.
