Panicle Rice Mite (Steneotarsonemus spinki) |
 |
Background
The rice mite, Steneotarsonemus spinki (S. spinki ) has been considered a serious rice pest in several Asian tropical regions. However, it was in the Americas that S. spinki assumed its largest economic importance. Yield losses in Central America have ranged from 30 to 90%. Until the present, S. spinki had not been found in rice crops in North America.
On July 13, 2007, USDA confirmed the detection of panicle rice mite (PRM), S. spinki, at a rice research facility in Alvin, Brazoria County, Texas. Interceptions of this pest have been reported at greenhouses in Ohio and Texas during the last 10 years. S. spinki has also been confirmed in Puerto Rico.
