Acarus farris hypopus found in stored wheat / 中国血吸虫病防治杂志

ABSTRACT

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 obvi-ous. The bristles on the hysterosoma were short,and the abdomen had a sucker plate. Conclusion There is A. farris hypopus breeding in the storage wheat,and its morphological characteristics is similar with the characteristics of A. siro hypopus.
