Selection for host-finding in Steinernema feltiae

Journal of Invertebrate Pathology, 1989
Abstract A hybridized Foundation population of the entomopathogenic nematode Steinernema feltiae was bidirectionally selected for enhanced and diminished host-finding ability. While there was no response to selection for diminished host-finding, 13 rounds of selection for enhancement produced a 20- to 27-fold increase.

Effect of temperature on the development of Steinernema carpocapsae and Steinernema feltiae (Nematoda: Rhabditida) in liquid culture

Applied Microbiology and Biotechnology, 2009
For commercial use of the entomopathogenic nematodes Steinernema carpocapsae and Steinernema feltiae in biological control of insect pests, they are produced in liquid culture on artificial media pre-incubated with their symbiotic bacteria Xenorhabdus nematophila and Xenorhabdus bovienii, respectively.

Phoresy of the entomopathogenic nematode Steinernema feltiae by the earthworm Eisenia fetida

Journal of Invertebrate Pathology, 2006
The free-living stage of entomopathogenic nematodes occurs in soil, and is an environmental-friendly alternative for biological control. However, their dispersal capability is limited. Earthworms improve soil characteristics, changing soil structure and influencing many edaphic organisms.

Control of sciarid flies with Steinernema feltiae in poinsettia cutting production

International Journal of Pest Management, 2003
The efficacy of Steinernema feltiae (UK strain) with the nominal concentrations of 0.65 and 1.3 million per table/m 2 against sciarids ( Bradysia spp.) in Jiffy plugs of poinsettia cuttings was studied on sand and ebb-and-flow tables during two summers under commercial production conditions.

Effect of host insect sterols on the development and sterol composition of Steinernema feltiae

Molecular and Biochemical Parasitology, 1986
Steinernema feltiae (= Neoaplectana carpocapsae), 'All' strain, was propagated in larvae of the corn earworm, Heliothis zea, which contained various sterols, in order to determine how the sterol composition of the host affects the growth, development and sterol composition of this insect-parasitic nematode.

Cryopreservation of the entomogenous nematode parasite Steinernema feltiae (=Neoaplectana carpocapsae)

Cryobiology, 1990
Abstract Cryopreservation studies were conducted with the J1 juvenile and third stage infective juvenile (IJ) larval stages of the entomogenous parasitic nematode Steinernema feltiae (= Neoaplectana carpocapsae). The main parameters evaluated were (i) tolerance of the organisms to the cryoprotectants methanol, ethanediol, glycerol, and dimethyl ...
