Huasteco pepper virus

Huasteco pepper virus (HuPV) is a devastating viral disease caused by a member of the Begomovirus genus within the Geminiviridae family. It poses a significant threat to solanaceous crop production, particularly in tropical and subtropical regions where environmental conditions favor the rapid spread of the disease.

The primary hosts for this virus are plants within the Solanaceae family, with chili and bell peppers being the most significantly affected. The virus can cause catastrophic losses in both commercial agricultural operations and home gardens, leading to reduced yield and high market rejection rates for damaged produce.

Infected plants exhibit severe symptoms including distinct chlorotic mosaic patterns on foliage, leaf distortion, curling, and significant stunting. Internodes become shortened, and the overall plant architecture is severely compromised. Fruits produced by infected plants are typically small, malformed, and lack the nutritional or visual quality required for sale.

The virus is transmitted by insect vectors, most notably the sweetpotato whitefly, Bemisia tabaci. The virus is acquired by the whitefly during feeding on infected plant sap and then transmitted to healthy hosts. High temperatures and humidity accelerate the whitefly life cycle, leading to rapid disease transmission throughout pepper plantations.

Since there are no curative measures for viral infections in plants, management must be strictly preventative. Key strategies include the integrated management of the whitefly population, the deployment of virus-resistant plant cultivars, adherence to strict crop rotation practices, and the consistent removal of reservoir weeds that host the virus throughout the year.

• Utilization of high-quality, virus-free transplant materials.
• Implementation of insect-proof netting in greenhouse facilities.
• Frequent scouting for whitefly populations and use of yellow sticky traps.
• Effective management of wild weed hosts near growing areas.
