【摘要】 <正>30年代,Archibald和Wagner在苏丹和其南非水道播种棕桐树(Balaniles aegylptiace),发现其果实掉入水中可减:少螺口密度。这一发现使得B.aegyptiaca被引进到Puerto Rico地区,种植在光滑双脐螺生长的水池周围,取得了明显的效果,这就是Archibald早期提倡的自然控制钉螺的方法,但当时并没有引起人们注意;这些植物含皂甙,在南非和南美洲用作毒鱼剂和肥皂。到六十年代中期,P.H.Goll等报告在埃塞俄比亚流行区用植物(Phytolacca dodecandra)可控制血吸虫病流行,草木植物,鸡矢藤、水芹等,对钉螺生长非常适宜;而益母草(Leonurus artemisia)等植物,则使钉螺生长受到抑制,凡种益母草的地方钉螺绝迹:更多还原

【Abstract】 Schistosomiasis is a disease that distribute widest in all parasitic disease. Control and eliminate Oncomelania hupensis which are intermediate hosts of Schistosoma trematodes is one of main methods against schistosomiasis.Tian Xing island where schistosomiasis is endemic is in the center of Yangzi River in Wuhan.In this article,through field investigation in Tian Xing island,we found out seven kinds of grass clump association. They are Cynodon dactylon(L.)Pers.Ass., Cyperus orthostachyus Franch. et Sav.Ass.,Polygonum .hydropiper Ass.,Leonurus artemisia (Louv.) S.Y.Hu Ass.Phragmites commuis Ass.,Alternanthera philoxeroides (Mart.) Griseb Ass.Humulus .scandens (Lour.),Merr Ass.. Through field investigation we found out that some species have positive relevance with Oncomelania hupensis (e.g.,Cynodon dactylon(L.)Pers.,Cyperus orthostachyus Franch. et Sav.)and some species have negative relevance with Oncomelania hupensis (e.g.,Alternanthera philoxeroides (Mart.) Griseb,Lartemisia (Louv.) S.Y.Hu).We can exorcize species that have positive relevance with Oncomelania hupensis or we can usher in species artificially,or we can promote growth of plants that can kill Oncomelania hupensis and let these plants become dominance species so that they can produce result of suppressing or killing the Oncomelania hupensis .更多还原
