Abstract
The efficiency with which the nematophagous fungus Arthrobotrys dasguptae attached to a range of plant parasitic nematodes was studied. Rotylenchus spp. and criconematid species retained many more detachable adhesive knobs than did other plant parasitic nematodes. More adhesive knobs were found on the anterior end of Rotylenchus robustus than on any other part of the body. The knobs attached only to one of the species tested in the genera Longidorus, Xiphinema, Trichodorus and Paratrichodorus. Tests with a range of fluorescent lectins indicated that only a restricted number of carbohydrate moieties were present on the cuticle of R. robustus whereas none were found on Xiphinema diversicaudatum. Saturating fungus and nematodes with these lectins or their specific carbohydrates did not affect the subsequent adhesion of A. dasguptae to the cuticle of R. robustus.
