Entomopathogenic nematodes (EPNs) respond to a variety of stimuli when foraging. In a laboratory investigation, we tested the chemotactic responses of 8 EPN strains (Steinernema and Heterorhabditis) to three mechanically damaged maize root compounds (linalool, α-caryophyllene and β-caryophyllene). We hypothesized that the EPN directional response to the(More)
Entomopathogenic nematodes (EPNs) play a role in indirect defenses of plants under attack by root herbivores. We have tested the chemotactic responses of 4 EPN species (Steinernema feltiae, S. carpocapsae, S. kraussei, and Heterorhabditis bacteriophora) to 5 compounds ([1] α-Pinene, [2] Terpinolene, [3] Bornyl acetate, [4] 2-Ethyl-hexanol, and [5] 2,(More)
Entomopathogenic nematodes (EPNs) play a role in indirect defense of plants under attack by root herbivores. Several investigations have shown that EPNs are attracted or repelled by various volatile compounds (VOCs) released from insect damaged plant roots. We hypothesized that the directional responses of EPNs to the VOCs would be affected by foraging(More)
In 2009, three Slovenian strains of entomopathogenic nematodes) and commercial product Entonem (active ingredient S. feltiae), were tested under laboratory conditions for their activity against adult cereal leaf beetles (Oulema melanopus). The nematode strains were tested at four different doses (250, 500, 1000, and 2000 infective juveniles/adult) and at(More)
BACKGROUND In order to increase our knowledge on the susceptibility of entomopathogenic nematode (EPN) species to agrochemicals, the compatibility of the infective juveniles (IJs) of the EPN (Steinernema and Heterorhabditis) with eight chemical and bio-insecticides was investigated under laboratory conditions. The effect of direct IJ exposure to(More)
We tested the chemotactic response of infective juveniles (IJs) of the entomopathogenic nematodes (EPNs) Steinernema feltiae, S. kraussei, Heterorhabditis bacteriophora, and S. carpocapsae, to the synthetic volatiles (dimethyl sulfide [DMS], dimethyl disulfide [DMDS], dimethyl trisulfide [DMTS], allyl isothiocyanate [AITC], phenylethyl isothiocyanate(More)
