To understand the breeding and morphology of 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 '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 , , lateral seta and sacral inner hair 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.
了解皖南高校食堂粉螨孳生情况及形态特征。
采集高校食堂揉面机、面粉袋及大米袋周围地面的粉尘和大米，置于显微镜下观察。
共采集108份样本，其中101份检出粉螨，检出率为93.52%。共发现粉螨1 527只，平均孳生密度为1.41只/克。在光学显微镜下观察，粉螨四对足自跗节向末端逐渐变细。背部刚毛坚硬，腹面刚毛光滑且相对较短。内垂直刚毛长于螯肢顶端。背毛、、侧毛和骶内毛最长。雌螨大于雄螨，雌螨肛毛多于雄螨。雌螨生殖褶几乎相连，前端有一新月形板覆盖。
皖南高校食堂粉螨孳生情况严重，应采取有效措施进行防治。
