Steinernema biddulphi n. sp., a New Entomopathogenic Nematode (Nematoda: Steinernematidae) from South Africa

A new species of entomopathogenic nematode (EPN), Steinernema biddulphi n. sp., was isolated from a maize field in Senekal, Free State Province of South Africa. Morphological and molecular studies indicated the distinctness of S. biddulphi n. sp. from other Steinernema species. Steinernema biddulphi n. sp. is characterized IJs with average body length of 663 mm (606–778 mm), lateral fields with six ridges in mid-body region forming the formula 2,6,2. Excretory pore located anterior to mid

The entomopathogenic nematode Steinernema feltiae is widely applied to control insect pests, such as scarab larvae, fungus gnats, and lepidopteran larvae (Toba et al., 1983; Jess and Bingham, 2004; Lacey et al., 2006; Lacey and Georgis, 2012).

Steinernema carpocapsae, which can stand upright on its tail, jump, tail-stand, and has low mobility has been classified as an ambush forager (Campbell and Gaugler, 1997; Bal et al., 2014). The majority of S. carpocapsae IJs do not actively engage in host-seeking chemotaxis behavior, even in

Activity of Steinernema colombiense in plant-based oils

Entomopathogenic nematodes (EPNs) in the genera Steinernema and Heterorhabditis are well-known biological control agents used against many arthropod species (Campos-Herrera, 2015; Lacey et al., 2015). They selectively search for insect hosts and kill them within 2 to 3 days with the aid of mutualistic bacteria of the genera Xenorhabdus and Photorhabdus, respectively (Adams et al., 2006; Dillman et al., 2012). Their worldwide distribution in soils (Kaya et al., 2006) and the availability of

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

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

Entomopathogenic nematodes (EPNs) in the genera Heterorhabditis and Steinernema are potent biocontrol agents that are used to control a wide variety of economically important insect pests (Shapiro-Ilan et al., 2017, 2018). The nematodes occur naturally in the soil and kill arthropod hosts with the aid of symbiotic bacteria (Xenorhabdus spp. bacteria are associated with steinernematid nematodes and Photorhabdus spp. bacteria are associated with heterorhabditid nematodes).

Biological characterization of the entomopathogenic nematode, Steinernema innovationi: a South African isolate

Entomopathogenic nematode species perform differently under different environmental conditions; therefore, the authors investigated the biological and environmental characteristics that could optimize performance of Steinernema innovationi. The authors studied the effect of temperature on infectivity and reproduction, the foraging behavior and host range. Thermal activity was optimal between 22 and 25°C. Highest infective juvenile (IJ) yields in last instar Galleria mellonella were observed at

first challenge in the development of these products is to get a combination of entomopathogenic agents (EAs) that favor a synergist or additive interaction in order to achieve an effective control because biological, environmental, and management factors influence the performance of EAs. The separate application of the entomopathogens Metarhizium spp., Heterorhabditis spp., and Steinernema spp. usually shows a good percentage of control over Phyllophaga spp., an edaphic pest that feeds on roots

Molecular Identification of Entomopathogenic Nematode Isolates from the Philippines and their Biological Control Potential Against Lepidopteran Pests of Corn

In search for local entomopathogenic nematode (EPN) species as a biological control agent of lepidopterous insect pests of corn, a survey for EPN in the major islands in the Philippines was conducted. Seven EPN populations from 279 soil samples were isolated using Ostrinia furnacalis, the key target insect pest of corn in the country, as bait. Analysis of the ITS1-5.8S-ITS2 ribosomal DNA sequence revealed the presence of Steinernema abbasi, Steinernema minutum, Steinernema tami, and

Postembryonic Ventral Nerve Cord Development and Gonad Migration in Steinernema carpocapsae

Steinernema carpocapsae is an entomopathogenic nematode widely studied for its properties as a biocontrol agent in insect pest management and as a model for understanding bacterial symbioses. Less attention has been given to the development of specific anatomical structures within S. carpocapsae. A better understanding of entomopathogenic nematode development and anatomy may lead to improved biocontrol efficacy. We recently demonstrated that the neuroanatomy of S. carpocapsae IJs differs from

However, such curative measures for control of S. exitiosa do not exist. Our objective was to measure the efficacy of the entomopathogenic nematode, Steinernema carpocapsae, as a curative control for existing infestations of S. exitiosa. In peach orchards, spring applications of S. carpocapsae (obtained from a commercial source) were made to infested trees and compared

First Report and Comparative Study of Steinernema surkhetense (Rhabditida: Steinernematidae) and its Symbiont Bacteria from Subcontinental India

Two populations (CS19 and CS20) of entomopathogenic nematodes were isolated from the soils of vegetable fields from Bijnor district, India. Based on morphological, morphometrical, and molecular studies, the nematodes were identified as Steinernema surkhetense. This work represents the first report of this species in India. The infective juveniles (IJs) showed morphometrical and morphological differences, with the original description based on longer IJs size. The IJs of the Indian

The Effects of Nutrient Concentration, Addition of Thickeners, and Agitation Speed on Liquid Fermentation of Steinernema feltiae

Entomopathogenic nematode production in liquid fermentation still requires improvements to maximize efficiency, yield, and nematode quality. Therefore, this study was aimed at developing a more suitable liquid medium for mass production of  Steinernema feltiae, by assessing the effects of nutrient concentration, thickeners (primarily agar), and agitation speed on infective juvenile (IJ) yield. Base medium (BM) contained yeast extract (2.3%), egg yolk (1.25%), NaCl (0.5%), and
