Aceria tosichella

Aceria tosichella is a species of mite in the family Eriophyidae. It is commonly known as the Wheat curl mite. This mite is a significant pest of wheat crops, causing damage through direct feeding and as a vector for plant diseases.

Description

The Aceria tosichella is a minute, worm-like mite. It is typically less than 0.2 mm long and has a white to transparent body. Unlike most mites, it has only two pairs of legs located at the front of the body.

Distribution

The Wheat curl mite is found worldwide, particularly in regions where wheat is grown. It has been reported in North America, Europe, Asia, Australia, and South America.

Life Cycle

The life cycle of Aceria tosichella includes four stages: egg, larva, nymph, and adult. The entire life cycle can be completed in as little as 7-10 days under optimal conditions.

Impact on Wheat Crops

Aceria tosichella is a major pest of wheat crops. The mites feed on the plant sap, causing curling and stunting of the wheat plants. More significantly, the mites are vectors for several plant diseases, including Wheat streak mosaic virus and High plains virus. These diseases can cause significant yield losses in infected crops.

Management

Management of Aceria tosichella in wheat crops involves a combination of cultural practices, such as crop rotation and the use of resistant wheat varieties, and chemical control using miticides.
