Predatory Activity of Nematode Trapping Fungi against the Larvae ofTrichostrongylus axeiandOstertagia ostertagi: A Possible Method of Biological Control

Abstract

Growth rate and activity of 10 nematode trapping fungi, (Hyphomycetes)—Arthrobotrys oligospora, Dactylaria brochopaga, D. gamsospora, D. polycephala, D. thaumasia, D. vermicola, Monacrosporium (Dactylella) bembicodes, M. {D.) cionopaga, M. {D.) ellipsospora, Trichothecium cystosporium—against the infective larvae ofOstertagia ostertagiandTrichostrongylus axeiwere studied. Species forming adhesive networks grew faster than the others. Species producing adhesive knobs, adhesive branches and constricting rings were, in general, slow growers.
