Abstract
WHILE screening a number of chemicals for their nematicidal action on the cysts of the potato root eelworm, Heterodera rostochiensis Wollenweber, one of us (A. Ph. W.) discovered an amœboid organism which attacks the larvæ of this nematode. The organism was encountered in the form of brownish spherical, single-walled hypnocysts1 25–40 µ in diameter, firmly sticking to the surface of the cysts of Heterodera. If larvæ leave the cyst subsequent to treatment with an aqueous solution of potato root diffusate, or if larvæ suspended in tap water are added, creeping trophic forms emerge from the hypnocysts. The phenomenon can be best observed if the bottom of the container is not too smooth. Probably for this reason very good results were obtained in the small cavities drilled in clear plastic, in which the observations were carried out. Glass containers or slides and hanging-drop preparations were not so satisfactory.
