Journal of Asia-Pacific Entomology, 1999
Abstract A symbiotic bacterium was identified from the entomopathogenic nematode, Steinernema carpocapsae, collected in Korea and its biological significance was examined for insecticidal and antibiotic effects. The symbiotic bacterium was isolated from the nematode-infected hemolymph of the fifth instar larvae of Spodoptera exigua.

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 ...

Adaptation of the entomopathogenic nematode, Steinernema carpocapsae, to insect food plant
Biological Control, 2003Abstract We conducted assays to determine if characteristics of entomopathogenic nematodes vary in response to continued exposure to a particular insect/host plant combination, and whether selection results in changed performance on other insect/host plant combinations.

They’ve got a ticket to ride: Xenorhabdus nematophila–Steinernema carpocapsae symbiosis
Current Opinion in Microbiology, 2007The association between the bacterium Xenorhabdus nematophila and the nematode Steinernema carpocapsae is emerging as a model system to understand mutually beneficial symbioses. X. nematophila, but not other Xenorhabdus species, colonize a discrete region of a specific developmental stage of S. carpocapsae nematodes.

Control of Cyparissius daedalus Cramer with the nematode Steinernema carpocapsae
Revista Palmas, 2004El barrenador gigante de la palma, Cyparissius daedalus, se ha convertido en una de las plagas más importantes en el cultivo de la palma de aceite, no sólo por el daño ocasionado en la producción, sino por la mortalidad que causa a las palmas. Como alternativa de control de larvas se evaluó el nematodo Steinernema carpocapsae.

Experimental Parasitology, 1988
The structure and concentration of sterol in a lipid-defined artificial medium affected the development of the entomogenous nematode, Steinernema feltiae (= Neoaplectana carpocapsae). The nematode grew normally in vitro when the medium was supplemented with delta 5-desalkylsterol (cholesterol) or delta 5-desalkylsteryl ester (cholesterol oleate).

Life history trait analysis of the entomopathogenic nematode Steinernema carpocapsae
NematologySummary The entomopathogenic nematode Steinernema carpocapsae is widely used for the biological control of insect pests. Mass production in liquid culture depends on the presence of its symbiotic bacterium Xenorhabdus nematophila ...

Role on serine protease inhibitors in the pathogenisis of Steinernema carpocapsae
2013ABSTRACT: Steinernema carpocapsae is an entomopathogenic nematode highly effective in the control of several insect pests, however the mechanisms involved in its parasitic process are not entirely known. The present study ascertains the role of serine protease inhibitors expressed by the parasitic stage of S. carpocapsae as potential virulence factors.
