NEMATODE-TRAPPING FUNGI: EVALUATION OF AXENIC HEALTHY AND GALLED ROOTS AS TRAP INDUCERS.

Larvae of Meloidogyne hapla Chit. induced abundant trap formation in the predaceous fungus Arthrobotrys conoides Drechs. Under similar aseptic conditions, neither healthy roots of Lycopersicon esculentum Mill, nor roots parasitized by the root-knot nematode induced traps.
