The behaviour of the fungi Arthrobotrys superba, A. dactyloides, Dactylaria
candida, Hohenbuehelia petalodes and Paecilomyces lilacinus towards Meloidogyne
sp. was investigated. Arthrobotrys superba trapped L2 juveniles of Meloidogyne
in vitro fastest and in largest numbers, followed by A. dactyloides and
Dactylaria candida (Fig.). Hohenbuehelia
was apathogenic; Paecilomyces infected
only eggs, which were killed. Arthrobotrys superba was more attractive
to Meloidogyne larvae than germinating tomato plants. There was no difference
in attractiveness between Dactylaria candida and germinating Lycopersicon.
Arthrobotrys dactyloides, Hohenbuehelia and Paecilomyces did not or hardly
attract Meloidogyne larvae. Arthrobotrys superba was the only fungus in
vivo to reduce the number of galls in Lycopersicon roots significantly
without damaging the plants. Arthrobotrys superba and A. dactyloides were
reisolated from natural experimental soil; A. oligospora was also isolated.
Hohenbuehelia developed fruit bodies.
