Abstract:
Invasion of potato roots by juveniles of Globodera rostochiensis (Ro. 1) was decreased by about 97% when the nematodes were treated with 1% sodium hypochlorite. This was possibly due to degradation of the amphidial exudate and subsequent damage to the exposed sensory apparatus. Concanavalin A and cationized ferritin, proteins which bound to amphidial exudate, had no effect on the ability of the juveniles to detect and migrate to disks of agar containing potato root diffusate, suggesting that surface mannose or glucose moieties were not active in capturing rapidly diffusing substances from agar discs. Sodium hypochlorite at 0.0017%, cetyl trimethylammonium bromide (CTAB) and spermidine reduced the ability of juveniles to perceive stimuli diffusing from discs on which potato roots had grown, without destroying the amphidial exudate. CTAB, however, altered the structure of the exudate. These smaller molecules may have passed rapidly through to the membranes of the sensillae to affect sensory reception. © 1988 BRILL.
