The development ofMoniezia expansain the intermediate host

Abstract

When eggs ofMonieza expansaare fed to galumnid mites, the onchospheres emerge in the intestine and migrate to the body cavity. Here they undergo metamorphosis and develop into cysticercoids. The dissection of mites, at various intervals after exposure, has yielded a successive series of developmental stages. Protocols of the experiments and photographs of living larvae are presented. These results demonstrate that mites serve as intermediate hosts ofMoniezia, and probably also of other anoplocephaline cestodes.
