Carpoglyphus lactis (Carpoglyphidae) infestation in the stored medicinal Fructus Jujubae.

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.

Objetivo: investigar la tasa de reproducción y densidad de cría de Carpoglyphus lactis en productos almacenados de Fructus jujubae en Anhui, China, con el fin de proporcionar una base científica para prevenir el deterioro de la fruta desecada de dicha categoría. Métodos: para la cría de C. lactis hemos recogido muestras de Fructus jujubae, que se mantuvieron a temperatura ambiente durante 6 meses, en la tienda de frutas secas o en el almacén de hierbas medicinales y se aislaron C. lactis de esas muestras. Se prepararon los especímenes del ácaro y se identificaron microscópica y morfológicamente. Resultados: C. lactis fue identificado en 19 de las 300 muestras, con densidad de cría y reproducción índice de 6,52 cabezas/g y 6,33%. La proporción de ácaros en las distintas fases de desarrollo fue: adultos (incluida la ninfa, 85,71%), larva (12,27%), hypopus (0,56%) y huevo (1,45%). El índice de riqueza, el índice de diversidad y el índice de uniformidad fue de 1,644, 1,644 y 0,923, respectivamente. Conclusión: el ácaro Carpoglyphus lactis infesta en gran cantidad los almacenes de Fructus jujubae de la provincia de Anhui (China). Por lo tanto, es urgente tomar medidas eficaces para prevenir la propagación del ácaro sobre productos secos almacenados en la misma habitación y la posible acariasis intestinal humana como consecuencia de la contaminación biológica (AU)

[Investigation on species and community ecology of cheyletoid mites breeding in the stored traditional Chinese medicinal materials].

OBJECTIVE: To investigate the species of Cheyletoid mites breeding status in the stored traditional Chinese medicinal materials and the relationship between its community and habitats. METHODS: A total of 60 samples of the traditional Chinese medicinal materials were collected from Huainan, Wuhu and Xuancheng in China. The mites were isolated with shakesieve shock, directicopy, Tullgren funnel, waternacopy and redricopy, and identified and counted under the light microscope. RESULTS: Cheyletoid mites were represented in 48 of the 60 samples, and the breeding rate accounted for as high as 80.0% (48/60). Totally, 6 species of Cheyletoid mites were identified, which belonged to Cheyletus, Acaropsis, Cheletomorpha, Eucheyletic and Pseudocheyles genera under the family of Cheyletidae. In the three investigated areas, the average breeding density of Cheyletoid mites was 109.75 heads/g, and average richness index was 1.54. The index of species diversity was 2.55 and the number of evenness was 0.95. CONCLUSION: This result entails positive prevention and control of the mite breeding in storage and processing of herbal materials.
