Investigation on the infestation and environment tolerance of Ornithonyssus bacoti in stored traditional Chinese herb Semen Coicis / 中华疾病控制杂志

Objective To investigate the infestation status and environment tolerance of ornithonyssus bacoti (O. bacoti) in stored traditional Chinese herb Semen Coicis (Coix seed). Methods 800 g of stored Semen Coicis was initially taken, and subjected to passing a 40-mesh sampling sieve. Then 80 g of Coix seed particles was sampled to directly isolate the mites that were made into slide specimen in conventional technique, and identified as the procedures described in previous literature. Results A total of 449 mites were isolated from the 80 g stored Semen Coicis particles, and were identified as O. bacoti. Conclusions O.bacoti was first detected in the stored traditional Chinese medicinal Semen Coicis with which infestation is serious. This status should call out attention to prevent the disease associated with transmission of pathogens from O.bacoti.

[Investigation of infestation of Carpoglyphus lactis in stored jujube from Anhui Province].

OBJECTIVE: To investigate the breeding of Carpoglyphus lactis in stored jujube from Anhui Province, so as to provide the evidence for preventing the harm of C. lactis to stored jujube. METHODS: The jujube samples stored for more than 6 months were collected from dried fruit shops and/or Chinese herbal medicine warehouses, which were chosen as survey sites in Anhui Province. The mites were isolated and identified under a microscope. RESULTS: Totally 19 samples infested with C. lactis were obtained from 300 samples in 17 cities of Anhui Province, the breeding rate and breeding density of C. lactis were 6.33% and 6.52 per gram respectively. The constituent ratios of different developmental stages were adult 85.72%, larva 12.27%, dormancy body 0.56%, and egg 1.45%, respectively. CONCLUSIONS: The breeding density of C. lactis in the stored jujube is high and the species diversity is rich, so the control of C. lactis and the prevention of human acariasis should be strengthened.

[Carpoglyphus lactis infestation in stored traditional Chinese medicine Arillus longan].

OBJECTIVE: To investigate the breeding of Carpoglyphus lactis in the storage Arillus longan, so as to provide the evidence for preventing the harm of C. lactis to traditional Chinese medicine. METHODS: Chinese herbal medicine warehouses were chosen as survey sites according to the breeding habits of mites, and the A. longan samples were stored more than 6 months. The mites were isolated and identified under a microscope. RESULTS: The C. lactis breeding rate was 20.0% (4/20) and the breeding density was 184.95 per sample. The constitute rates of adult, larva, dormancy body and egg were 58.39%, 30.41%, 0.06%, and 11.14% respectively. CONCLUSIONS: The breeding density of C. lactis is high in the stored A. longan, so the control and prevention of human intestinal acariasis should be strengthened.

[Investigation and morphological observation of Histiostoma feroniarum breeding in Chinese herbal medicine Rhizoma Zingiberis].

OBJECTIVE: To understand the breeding situation of Histiostoma feroniarum in Chinese herbal medicine Rhizoma Zingiberis. METHODS: The Rhizoma Zingiberis sold on the market was selected and brushed. The dust from Rhizoma Zingiberis was screened under a microscope to search the mites. The mites were made into specimens to identify the species. RESULTS: The mites were H. feroniarum. Totally 14 mites were found in 100 g dust sample, with the density of breeding of 0.14/g. CONCLUSIONS: H. feroniarum could breed in Chinese herbal medicine Rhizoma Zingiberis, and the prevention and control measures should be adopted.

[Investigation on species of Limacodidae on Prunus cerasifera and sycamore in urban area of Wuhu City].

OBJECTIVE: To investigate the species of Limacodidae and the biological habits on Prunus cerasifera and sycamore in the urban area of Wuhu City, so as to provide the reference for the prevention and control of the diseases caused by Limacodidae. METHODS: Two observation places were selected in the urban area of Wuhu City, and the survey period of the first observation place (A) was from 2014-5-4 to 2014-11-2, and eucleid caterpillar was observed and collected every Sunday (a total of 27 times); the survey period of the second observation place (B) was from 2014-1-5 to 2014-12-28, and eucleid caterpillar was observed and collected every Sunday (a total of 52 times). The eucleid caterpillars were collected by the visual inspection and artificial direct collecting method, and then they were identified and classified by the naked eye direct observation and the direct observation with the help of the anatomical lens in the laboratory. RESULTS: There were seven kinds of identified Limacodidae from the two observation places and their occurrence regularity, the species composition ratio, and natural enemies were understood. CONCLUSIONS: Limacodidae larvae not only are the defoliator of the ornamental forests, but also harm the health of residents, that is they can cause eucleid larva dermatitis. Therefore, we should strengthen the prevention and control of Limacodidae, reducing its impact on the lives of the residents.

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

OBJECTIVE: To investigate the species of Acaroid mites breeding in the stored traditional Chinese animal medicinal materials and the relationship between its community and habitats. METHODS: A total of 30 samples of traditional Chinese animal medicinal herbs were collected from Wuhu City, Anhui Province, China. The mites were isolated by the directly microscopic and floatation microscopic examinations, and then identified and counted under a light microscope. RESULTS: Acaroid mites was represented in 28 of the 30 samples, and the breeding rate accounted for as high as 93.3% (28/30). Totally, 13 species of Acaroid mites were identified, which belonged to 4 families and 9 genera. The densities of Acaroid mites were top in 6 Chinese herbal medicines, such as corium erinacei, aspongopus, hirudo, pheretima aspergillum, Apostichopus and huechys. The diversity parameters of these six traditional Chinese animal medicinal herbs were calculated. The highest richness indexes were in aspongopus and hirudo, the highest diversity index was in hirudo, and the highest evenness index was in Apostichopus. CONCLUSIONS: There are Acaroid mites breeding in parts of the traditional Chinese animal medicinal herbs stored in Wuhu. In the storage and processing of Chinese herbal medicines, we should pay attention to the prevention and control of mites.
