What is wheat vector?

Wheat vector, also known as wheat curl mite or simply WCM, is a microscopic pest that feeds on wheat plants and can transmit damaging viruses. They are usually 0.2-0.3mm long and are too small to be seen with the naked eye.

These mites are predominantly found in the Great Plains region of the United States, especially in areas where wheat is commonly grown. They are typically active in the fall when wheat plants are emerging, and can cause significant yield losses if not properly managed.

Wheat vector mites can transmit several viruses that cause a variety of wheat diseases, including wheat streak mosaic virus, High Plains virus, and triticum mosaic virus. These viruses can cause reduced yield, stunted growth, or even death of infected plants.

Controlling wheat vector mites involves several management practices, including crop rotation, eliminating volunteer wheat plants, and applying appropriate insecticides at the right time. Early detection and prevention measures are important to avoid severe yield losses and minimize crop damage caused by these pests.
