The effect of changes in the osmotic pressure upon Hammerschmidtiella diesingi (Hammerschmidt, 1838) with reference to the survival of the nematode during moulting of the cockroach
Published online by Cambridge University Press: 06 April 2009
Extract
Females of Hammerschmidtiella diesingi can survive in the hind-gut of moulting Blatta orientalis. After a period of shrinkage they recover their normal length within 24 hr. in 0·2 and 0·3 m sodium chloride and in 50% sea water, but not in hypotonic media or in hypertonic sucrose. Females of H. diesingi, which have regained their original length in hypertonic media, swell when placed in normally isotonic media; a similar phenomenon occurs with nematodes taken from moulting cockroaches.
