Effects of fertilizers on virulence of Steinernema carpocapsae

Applied Soil Ecology, 1996
Abstract The effects of three fertilizers (fresh cow manure, composted manure, and urea) were determined on the virulence of Steinernema carpocapsae (Weiser) against the greater wax moth, Galleria mellonella (L.). Nitrogen levels were standardized among fertilizer treatments at two levels (280 and 560 kg ha−1).

Entomopathogenic nematode Steinernema carpocapsae (Weiser) (Rhabditida: Steinernematidae), a new member of Slovenian fauna

Acta Agriculturae Slovenica, 2008
In April 2008, 120 soil samples from 24 locations were collected in Gorenjska, Notranjska and Primorska regions as well as in Ljubljansko barje. The presence of entomopathogenic nematodes was confirmed in 9 samples from 6 locations. Only the sample C101,

Ultrastructure changes in the haemocytes of Galleria mellonella larvae treated with gamma irradiated Steinernema carpocapsae BA2

Journal of Radiation Research and Applied Sciences, 2014
The ultrastructure studies on the haemolymph of 5th larval instar of Galleria mellonella showed five types of haemocytes; Prohaemocytes, Plasmatocytes, Granulocytes, Oenocytoids and Spherulocytes.

Osmotic responses of different strains of Steinernema carpocapsae

Nematology, 2011
Abstract A solution consisting of a mixture of glycerol and fortified artificial seawater was used to induce partial anhydrobiosis at 15°C in different strains of Steinernema carpocapsae. All the strains tested were tolerant to the osmotic solution and the survival and infectivity of the nematodes were not influenced.

Potential of Steinernema carpocapsae (Weiser) as a biological control agent against potato tuber moth, Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae)

Journal of Integrative Agriculture, 2020
The entomopathogenic nematode, Steinernema carpocapsae, was evaluated for control of the potato tuber moth, Phthorimaea operculella, under laboratory conditions. We evaluated different concentrations of S.

A ShK-like Domain from Steinernema carpocapsae with Bioinsecticidal Potential. [PDF]

Toxins (Basel), 2022
Entomopathogenic nematodes are used as biological control agents against a broad range of insect pests. We ascribed the pathogenicity of these organisms to the excretory/secretory products (ESP) released by the infective nematode. Our group characterized different virulence factors produced by Steinernema carpocapsae that underlie its success as an ...

Evaluation of Steinernema carpocapsae survival and infectivity after cryopreservation

BioControl, 2016
A cryopreservation protocol, with an optimum survival rate of 86.8 %, was developed for a strain of Steinernema carpocapsae (Weiser) ItS-CAO1 isolated in a lagoon plain in Veneto Region (northern Italy). Some laboratory bioassays were carried out against Galleria mellonella (L.) (Lepidoptera: Pyralidae) larvae to determine the infectivity and stability

Dry-freezing Steinernema carpocapsae infective juveniles for robust preservation of stocks. [PDF]

MicroPubl Biol, 2023
Cryopreservation allows strains to be stored, eliminating genetic drift and maintenance costs. Existing cryopreservation methods for the economically-important entomopathogenic nematode Steinernema carpocapsae involve multiple incubation and filtration steps to precondition the animals.

Steinernema carpocapsae jumps with greater velocity and acceleration than previously reported. [PDF]

MicroPubl Biol, 2021
Many invertebrates are capable of jumping, such as locusts, fleas, mantids, and cockroaches. Some invertebrates can jump without the use of their legs, such as click beetles and springtails (Mo et al., 2020). Nematodes, which are non-segmented roundworms, are capable of a variety of complex behaviors, though jumping is arguably the most visually ...
