[A preliminary survey of acaroid mite breeding in farmer home storages].

OBJECTIVE

To investigate the densities and species of acaroid mites in stored products in farmer home storages.

METHODS

The mite samples which were collected from the farmers'home in Linquan County, Anhui Province included grains, foods, condiments, fruits and vegetables, and the breeding mites were isolated, then identified and classified after using the mites to make slide specimens.

RESULTS

Twenty-one species of acaroid mites were obtained, belonging to 7 families and 15 genera. The highest breeding density was in the millet (3 888.89 mite/g) and the lowest was in the fennel (2.03 mite/g), and the frequent breeding species of storages were and . The average breeding density of acaroid mites in grains was 383.94 mite/g, and the dominant mite species was . The average breeding density of acaroid mites in condiments was 149.53 mite/g, and the dominant mite species were and . The average breeding density of acaroid mites in foods was 85.15 mite/g, and the dominant mite species were , , , and . The average breeding density of acaroid mites in fruits and vegetables was 49.15 mite/g, and the dominant mite species were and . The average breeding density of acaroid mites in other stored products was 25.05 mite/g, and the dominant mite species were and .

CONCLUSIONS

The species of acaroid mites in home storages are very rich, and it is necessary to take positive measures to reduce the infestation of acaroid mites.
