Abstract
To understand the breeding and morphology of Lepidoglyphus destructor in college canteens in south Anhui Province. The powder and rice on the floor around dough makers, flour bags and rice bags in college canteens were collected and observed under a microscope. Totally 108 samples were collected, and Acaroid mites were found in 101 of them with a detection rate of 93.52%. Totally 1 527 mites were found with an average breeding density of 1.41/g. Under the light microscope observed, the L. destructor's four pairs of legs were tapering from tarsus. The back setae were stiff and the ventral setae were smooth and relatively short. The internal vertical seta was longer than the top of the chelicera. Dorsal seta d3, d4, lateral seta l3 and sacral inner hair sai were the longest. The female mites were bigger than the male ones, and had more anal seta than male ones. The genital fold of female mites almost connected together, and the front-end had a crescent shaped plate cover. The breeding of Acaroid mites in college canteens is serious, and therefore, effective measures should be taken to prevent and control it.
