ABSTRACT
This study was designed to detect the intensity of the attraction and repulsion of nematodes to several fungi. Of the 14 fungi tested, 11 attracted root-knot nematodes, one repelled nematodes, and two were neutral. The attraction intensity was directly proportional to time and based on the nutrients provided by the nematodes. In this experiment, the nematophagous fungi Arthrobotrys oligospora, A. superba, A. musiformis, Dactylella oviparasitica, Clonostachys rosea, Stropharia rugosoannulata, Lecanicillium muscarium, Trichoderma harzianum, T. viride, Pleurotus ostreatus, and Monacrosporium ellipsosporum demonstrated a prominent attraction intensity. The attraction intensity of all these fungi increased with time, while that of two fungi, Dactylaria gracilis and A. dactyloides, remained neutral throughout the experiment. Only the fungus species A. arthrobotryoides repelled the nematodes.
