[Hemocyte morphology and classification in Oncomelania hupensis].

Zhongguo ji sheng chong xue yu ji sheng chong bing za zhi = Chinese journal of parasitology & parasitic diseases, 2015
Hemocytes were collected from Oncomelania hupensis in Junshan, Hunan Province and Puge, Sichuan Province, respectively, and stained with Giemsa solution for light microscopic examination. The cells were classified morphologically. Five types of hemocytes were identified, viz., large acidophilic hyalinocytes, small acidophilic hyalinocytes, basophilic ...

A model for the prediction of Oncomelania hupensis in the lake and marshland regions, China

Parasitology International, 2008
A model has been developed for predicting the density of Oncomelania hupensis, the intermediate host snail of Schistosoma japonicum. The model takes into account different environmental factors, including elevation, air and soil temperature, type of vegetation, mean height of preponderant vegetation and soil humidity.

[Progress of research on taxonomy of Oncomelania hupensis].

Zhongguo xue xi chong bing fang zhi za zhi = Chinese journal of schistosomiasis control, 2013
In the early periods, the research on taxonomy of Oncomelania hupensis mainly focused on the traditional methods--morphology and anatomy, and then numerical taxonomy, cytogenetics, and population genetics are used in this discipline. With the advance of the molecular biology techniques, emerging technologies, such as restriction fragment length ...

[Effect of Nerium indicum on killing Oncomelania hupensis].

Ying yong sheng tai xue bao = The journal of applied ecology, 2002
A laboratory experiment at 20 +/- 5 degrees C shows that the water extract of fresh Nerium indicum had an obvious effect on killing Oncomelania hupensis. Treated with 0.1% water extract for four days, the mortality of O. hupensis was up to 100%. The effect of different tissues of N. indicum on O.

[Morphology and phagocytic activity of hemocytes of Oncomelania hupensis].

Zhongguo ji sheng chong xue yu ji sheng chong bing za zhi = Chinese journal of parasitology & parasitic diseases, 1994
Hemocytes from Oncomelania hupensis hemolymph were studied in vitro. Spreading amoebocytes were the most common cell type. The average sizes of amoebocytes from Anhui and Yunnan were 8.42 +/- 0.73 x 7.46 +/- 0.52 microns and 7.63 +/- 0.65 x 6.85 +/- 0.54 microns, respectively.

[Wetland protection and Oncomelania hupensis control].

Zhongguo xue xi chong bing fang zhi za zhi = Chinese journal of schistosomiasis control, 2014
The wetland is the unique ecosystem that is formed by the interaction between water and land on the earth surface. At present, the wetland ecology and wetland protection is becoming a more and more attention. Oncomelania hupensis is also a wetland creature that is the only snail host for spreading schistosomiasis japonica.
