In Slovenia only recently entomopathogenic nematodes were recorded for the first time. In the beginning of 2007, the presence of Steinernema affine was confirmed. During the further investigations in the same year Steinernema feltiae was recorded on the arable field near Cerknica. In the previous year this field was planted with chicory. In Slovenia, until now the entomopathogenic nematodes had...

—I hypothesized that the naturally elevated Ni concentration of Melanotrichus boydi (718–789 mg g21) might protect this insect species against pathogen attack. I contrasted survival of M. boydi against survival of the low-Ni mirid Lygus hesperus when treated with three entomopathogenic biocontrol agents. Biocontrol agents used were the fungus, Beauveria bassiana, and infective juveniles of two ...

The objective of this study was to determine the susceptibility of the two primary direct insect pests of hazelnuts in Oregon to three species of entomopathogenic nematodes. The entomopathogenic nematodes (Heterorhabditis marelatus Pt. Reyes, Steinernema carpocapsae All and Steinernema kraussei L137) were used in laboratory soil bioassays to determine their virulence against filbertworm, Cydia ...

The production of an ant-deterrent factor(s) (ADF) by Xenorhabdus nematophila and Photorhabdus luminescens, the symbiotic bacteria of the nematodes Steinernema carpocapsae and Heterorhabditis bacteriophora, respectively, was examined. In addition to an in vivo assay in which bacteria were tested for their ability to produce ADF within insect cadavers (M.E. Baur, H. K. Kaya, and D. R. Strong, Bi...
