Intraguild predation among biological-control agents: theory and evidence
Abstract Theoretical and empirical evidence developed in four subdisciplines of biological control (biocontrol of plant pathogens, weeds, nematodes, and arthropods) is brought to bear upon a shared… Expand

Nematode-trapping fungi of a natural shrubland: Tests for food chain involvement
We describe the spatial and temporal pat- terns in the abundance of nematode-trapping fungi and in suppression of nematodes in a coastal shrub- land. A previous study at this location (Bodega Ma-… Expand
Trap production by nematophagous fungi growing from parasitized nematodes
Nematode-trapping fungi are generally considered facultative parasites that produce traps only under special conditions. However, Arthrobotrys dactyloides, A. oligospora, Monacrosporium… Expand
Effects of a common harvester ant (Messor andrei) on richness and abundance of soil biota
Soil biota and chemistry were compared between harvester ant (Messor andrei) nests and adjacent, non-ant soil from a semi-arid, serpentine grassland. The major soil groups (bacteria, fungi,… Expand
Alginate Pellet Formulation of Hirsutella rhossiliensis for Biological Control of Plant-Parasitic Nematodes
Abstract Vegetative colonies of the nematophagous fungus Hirsutella rhossiliensis were grown in shake culture, rinsed free of media, macerated, and pelletized in 1% alginate. Nondried or dried (1 day… Expand
Soil pH and the Activity of a Pelletized Nematophagous Fungus.
ABSTRACT When formulated as assimilative hyphae in alginate pellets, the nematophagous fungus Hirsutella rhossiliensis was more active (i.e., parasitized more assay nematodes) in an acidic vineyard… Expand
Tests for Density-Dependent Parasitism of Nematodes by Nematode-Trapping and Endoparasitic Fungi
Abstract The relationship between parasitism by fungi and density of host nematodes (juveniles of Meloidogyne javanica ) was examined in soil microcosms. One of five fungi ( Hirsutella rhossiliensis… Expand

We studied the population biology of the nematophagous fungus Hirsutella rhossiliensis to understand its potential as a biological control agent. Because the fungus is an infectious and transmissible… Expand
