[ Acarus farris hypopus found in stored wheat].

OBJECTIVE: To observe the morphological characteristics of Acarus farris hypopus.

METHODS: The breeding mites from stored wheat samples were separated by a shake sieve and direct microscope. The isolations were used for slide preparation, and then the slide was observed under a light microscope for mite identification.

RESULTS: The A. farris hypopus was found in the collected wheat samples. Under the microscope the boundary between the propodosoma and hysterosoma of the hypopus was obvious. The bristles on the hysterosoma were short, and the abdomen had a sucker plate.

CONCLUSIONS: There is A. farris hypopus breeding in the storage wheat, and its morphological characteristics is similar with the characteristics of A. siro hypopus.
