▪ Abstract Empirical research has not supported the prediction that populations of terrestrial
herbivorous arthropods are regulated solely by their natural enemies. Instead, both natural …

Plants influence the behavior of and modify community composition of soil-dwelling
organisms through the exudation of organic molecules. Given the chemical complexity of the …

Naturally occurring entomopathogens are important regulatory factors in insect populations.
Many species are employed as biological control agents of insect pests in row and …

We discuss the behavior and ecology of entomopathogenic nematodes in relation to their
successes and failures as biological control agents. Four categories of studies have been …

Several species of entomopathogenic nematodes in the families Steinernematidae
(Steinernema) and Heterorhabditidae (Heterorhabditis) are being produced commercially …

Entomopathogenic nematodes in Steinernema, together with their symbiont bacteria
Xenorhabdus, are obligate and lethal parasites of insects that can provide effective …

This chapter discusses some aspects (bacterial taxonomy and co-speciation with
nematodes, phenotypic variation, pathogenicity, and isolation of symbionts and …

Entomopathogenic nematodes and the chloronicotinyl insecticide, imidacloprid, interact
synergistically on the mortality of third‐instar white grubs (Coleoptera: Scarabaeidae). The …

Biological control manipulations of natural enemies to reduce pest populations represent
large-scale ecological experiments that have both benefited from and contributed to various …
