Objective: To investigate the breeding rate and breeding density of Carpoglyphus lactisin stored Fructus Jujubaein Anhui, China in order to provide a scientific basis for prevention of Carpoglyphus lactis (C. lactis)from spoiling the dried fruit of such category.Methods: By the breeding nature of C. lactis,we collected samples of Fructus Jujubae, which were kept over 6 months in general, from the dried fruit shop and (or) Chinese herbal medicine warehouse, and isolated C. lactisfrom those samples. The mite specimens were prepared, and microscopically and morphologically identified.Results: C. lactiswas identified in 19 of the 300 samples, with breeding density and breeding rate of 6.52 heads/g and 6.33%. Constitute ratio at distinct developmental phase was associated with adult (including nymph, 85.71%), larva (12.27%), hypopus (0.56%) and egg (1.45%), respectively. The richness index, diversity index and evenness index was 1.644, 1.644 and 0.923, respectively.Conclusion: Carpoglyphus lactis appears infesting in large quantity in the Fructus Jujubaestored in the above places in Anhui province, and the density is higher. Therefore, it is urgent to take effective measures to prevent C. lactisfrom spreading over other dried products stored in the same room and potential human intestinal acariasis as a result of the biological contamination.
