Steinernema feltiae Intraspecific Variability: Infection Dynamics and Sex-Ratio. [PDF]

J Nematol, 2014
Entomopathogenic nematodes (EPNs) from the Heterorhabditidae and Steinernematidae families are well-known biocontrol agents against numerous insect pests. The infective juveniles (IJs) are naturally occurring in the soil and their success in locating and penetrating the host will be affected by extrinsic/intrinsic factors that modulate their foraging ...

ENTOMOPATHOGENIC NEMATODES ASSOCIATION WITH SOIL- DWELLING BACTERIA: THE CASE OF STEINERNEMA FELTIAE

Redia
The symbiosis of entomopathogenic nematodes (EPNs) with bacteria in the genera Photorhabdus and Xenorhabdus is well known. However, other soil-dwelling bacteria can occasionally be isolated from EPNs collected from diseased larvae. Accordingly, through several studies, we have detected the presence of diverse bacterial species including isolates of ...

How effective are entomopathogenic nematodes for vine weevil (Coleoptera: Curculionidae) biological control? A meta-analysis. [PDF]

Pest Manag Sci
Entomopathogenic nematodes provide reliable biological control of vine weevil larvae, reducing populations by 63% on average. All five tested species are effective, with temperature (18–30 °C) being the strongest predictor of success. Abstract BACKGROUND Vine weevil (Otiorhynchus sulcatus) is a globally important pest of soft fruit and ornamental crops

HAPLOTYPE DIVERSITY OF STEINERNEMA FELTIAE (NEMATODA: STEINERNEMATIDAE) IN EURASIA

Redia, 2020
Phylogenetic analysis of ITS rDNA sequences of the entomopathogenic nematode Steinernema feltiae Filipjev, 1934 (Wouts, Mráček, Gerdin and Bedding, 1982) was used to infer intraspecific genetic variability of this rhabditid nematode. Nucleotide intraspecific differences among S. feltiae isolates reached the level of 19 base pairs per ITS rDNA region, i.

Virulence and biocontrol potential of entomopathogenic nematodes against soil-dwelling stages of the small hive beetle under laboratory and semi-field conditions. [PDF]

Pest Manag Sci
Entomopathogenic nematodes (EPNs) are virulent against multiple life stages of Aethina tumida in the laboratory. EPNs significantly reduce adult emergence in natural and autoclaved sterile soil under semi‐field glasshouse conditions. Abstract BACKGROUND The small hive beetle (SHB; Aethina tumida) is a significant pest affecting honey bees and the ...

Identifying key parameters for reliable assessment of entomopathogenic nematodes viability as affected by spray application stress-related factors. [PDF]

Pest Manag Sci
Commercial entomopathogenic nematodes (EPNs) were exposed to stress simulating spray application conditions, for viability assessment using different methods. Temperature impacted non‐lethal stress earlier than survival and activity, emphasizing the importance of measuring these parameters to assess pesticide application equipment (PAE) impact on EPN ...

Potential of entomopathogenic nematode‐infected insect cadavers for the biocontrol of the red imported fire ant Solenopsis invicta

Pest Management Science, Volume 79, Issue 11, Page 4383-4389, November 2023., 2023
In Solenopsis invicta management, Steinernema riobrave (Sr)‐infected cadavers carrying the next generation of emerging nematode‐infective juveniles may prevent ant relocation and colony splitting as a result of disturbances encountered during the inundative method. The mortality of S.

Re-assessing the infection strategies of the entomopathogenic nematode Steinernema feltiae (Rhabditidae; Steinernematidae) [PDF]

, 2000
Previous studies have indicated that between 60 and 80% of a population of entomopathogenic nematodes do not infect their insect hosts at any one period in time.

Ice-Active Substances from the Infective Juveniles of the Freeze Tolerant Entomopathogenic Nematode, Steinernema feltiae. [PDF]

PLoS One, 2016
Steinernema feltiae is a moderately freezing tolerant nematode, that can withstand intracellular ice formation. We investigated recrystallization inhibition, thermal hysteresis and ice nucleation activities in the infective juveniles of S. feltiae.
