First record of native entomopathogenic nematodes from Montana agroecosystems

Entomopathogenic nematodes (EPNs), which occur naturally in soils, are obligate parasites of soil-inhabiting insects. EPNs were first described in 1923 with the identification of Aplectana kraussei Steiner (now known as Steinernema kraussei) (Nguyen and Hunt, 2007). Steinernematidae and Heterorhabditidae are two major families of EPNs with potential for managing insect populations (Kaya and Gaugler, 1993; Georgis et al., 2006). EPNs are associated with endosymbiotic bacteria belonging to the

Natural occurrence and distribution of entomopathogenic nematodes (Steinernematidae, Heterorhabditidae) in Viti Levu, Fiji Islands

Entomopathogenic nematodes (EPNs) species belonging to the genera Steinernema Travassos, 1927 and Heterorhabditis Poinar, 1975 and their symbiotic bacteria from genera Xenorhabdus and Photorhabdus, respectively, are lethal parasites of soil inhibiting insects (Shapiro-Ilan et al., 2017). Globally, EPNs are being widely researched as promising biocontrol agents for wide range of agricultural pests (Lacey et al., 2015). Because of the increasing awareness of EPN as an effective non-chemical

Very often, in an attempt to control PPN, the beneficial entomopathogenic nematodes (EPN) are harmed by bionematicides or organic amendments (Bednarek and Gaugler, 1997; Somasekhar et al., 2002). Entomopathogenic nematodes are widely used by farmers and growers commercially for biological control of insect pests (Somasekhar et al., 2002).

Survival and Infectivity of Entomopathogenic Nematodes Formulated in Sodium Alginate Beads

An alternative control method to the use of chemical insecticides against soil dwelling insect pests is the application of entomopathogenic nematodes formulated in alginate beads for enhanced shelf life. The aim was to compare the benefit on nematode survival and infectivity of: (i) pre-conditioning of juveniles, and (ii) coating of alginate beads. The nematodes Steinernema glaseri, Steinernema carpocapsae, and Heterorhabditis bacteriophora were reproduced in last instar larvae of the wax moth

Entomopathogenic nematodes of the families Steinernematidae Travassos, 1927 and Heterorhabditidae Poinar, 1976 are obligate lethal pathogens of insects with a worldwide distribution (Adams et al., 2007; Hominicki, 2002; Spiridonov and Subbotin, 2016). These organisms are commercially produced and used as biological control of insect pest populations (Shapiro-Ilan et al., 2002).

Virulence of Steinernema ceratophorum against different pest insects and their potential for in vivo and in vitro culture

Entomopathogenic nematodes (EPN) of the genera Steinernema Travassos and Heterorhabditis Poinar are natural parasites of many insects (Kaya and Gaugler, 1993). The infective juveniles (IJ) of EPN harbor the symbiotic bacteria Xenorhabdus Thomas and Poinar and Photorhabdus Boemare in their intestines (Boemare, 2002; Poinar, 1990; Qiu et al., 2009). The EPN-bacteria complex actively searches, infects and kills the host, propagates in the host, and produces progeny to start a new life cycle after

Several methods are studied for the control of phytonematodes (Rosa et al., 2015; Silva et al., 2014). Studies show that entomopathogenic nematodes (EPNs) have potential for biological control of these parasites (Pérez and Lewis, 2004; Lewis and Grewal, 2005). In view of the above, the objective of the present study was to evaluate the hatching, mortality and infectivity of hatched juvenis of M

In vivo production of entomopathogenic nematodes using Galleria mellonella: costs and effect of diets on nematode pathogenicity

The use of biological agents, such as entomopathogenic nematodes (EPN) of the genera Heterorhabditis and Steinernema, is one of a range of tools for biological control. These nematode species are obligate parasites, lethal, and easy to apply (San-Blas, 2013). They can be mass-produced using in vivo or in vitro (solid or liquid) culture methods (Gaugler and Han, 2002; Rahoo et al., 2019), but in vivo is the method of choice for laboratory-scale production (e.g. for generating material for field

Reclaimed desert habitats favor entomopathogenic nematode and microarthropod abundance compared to ancient farmlands in the Nile Basin

Research on entomopathogenic nematodes (EPN) in Egypt started in the 1970s, and focused heavily on imported, non-indigenous species (Abd-Elgawad, 2017). Surveys to isolate and identify indigenous EPNs began two decades later (Shamseldean and Abd-Elgawad, 1994). Inconsistent efficacy by expensive EPN products hinders their use by the Egyptian farmers, suggesting a need for further exploration to identify species which are adapted to North African conditions and best suited to infect local insect

Beneficial nematodes are used as biological control agents. Low-cost mass production of entomopathogenic nematodes (EPNs) is an important prerequisite toward their successful commercialization. EPNs can be grown via in vivo methods or in sold or liquid fermentation. For solid and liquid approaches, media optimization is paramount to maximizing EPN yield and quality.

In Mexico, EPNs, particularly species of the genera Steinernema and Heterorhabditis, have been isolated in the desert, forests, and arable areas (Lezama et al., 2001; Stock et al., 2009). Worldwide, the main studies and reported isolates have come from these genera. Recently, two new species of EPNs
