Non-permissive host

Fig. 11.5. Hymenolepis diminuta comparative development in the rat (the natural definitive host) and the mouse (a non-permissive host). In most mice, growth ceases abruptly on day 10+1 and destrobilisation commences, leaving only a scolex and a neck 0.5-2 mm in length. (Modified from Hopkins et at., 1972.)...

It is interesting that parasitism by . sonorensis of two non-permissive hosts, the velvetbean caterpillar, Anticarsia gemmatalis. and the bertha armyworm, Mamestra configurata, did not stimulate the production of the glycoprotein by those hosts (107).
