Entomopathogenic nematode management of small hive beetles (Aethina tumida) in three native Alabama soils under low moisture conditions

ambush (sit and wait) techniques while Heterorhabditis spp. hunt using cruising (seek and attack) techniques (Ellis et al., 2010; Lewis et al., 1992; Wilson et al., 2012). Six EPN species that have shown promise in laboratory bioassays for controlling A. tumida are Heterorhabditis bacteriophora (Poinar, 1975) Heterorhabditis indica (Poinar et al., 1992) Steinernema carpocapsae (Weiser, 1955), Steinernema feltiae (Filipjev, 1934), Steinernema kraussei (Steiner, 1923), and Steinernema riobrave

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

Touch-stimulation increases host-seeking behavior in Steinernema Carpocapsae

intermediate foragers based on several characteristics including their mobility and whether or not they can tail-stand (Lewis et al., 1992; Campbell and Gaugler, 1993; Lewis et al., 1993; Campbell and Gaugler, 1997). 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

Curative Control of the Peachtree Borer Using Entomopathogenic Nematodes

established infestations would limit damage to the tree and prevent the next generation of S. exitiosa from emerging within the orchard. 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

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

Conspecific pheromone extracts enhance entomopathogenic infectivity

pheromones (Kaplan et al., 2012). Presumably due to these dispersal pheromones, crude macerate of EPN-infected hosts was shown to enhance EPN dispersal in a soil profile (Wu et al., 2018). In agreement with these findings, dispersal pheromone extracts from host cadavers enhanced movement of Steinernema carpocapsae (Weiser) and S. feltiae (Filipjev) in soil columns, and in greenhouse trials they enhanced efficacy (Oliveira-Hofman et al., 2019). Prior to our research here, it was not known whether EPN

Quantification of pH tolerance levels among entomopathogenic nematodes

soils, as the ability of the nematodes to find hosts can be inhibited in such soils (Fischer and Führer, 1990), while others tend to thrive in moderate to neutral pH conditions (Hussaini et al., 2004). Clearly, pH can hinder the efficacy of these nematodes, thereby affecting the intended level of biocontrol. Although pH has been shown to affect the survival of Steinernema carpocapsae and Heterorhabditis indica (Hussaini et al., 2004) and S. carpocapsae and S. glaseri (Kung et al., 1990b) differently

These were: an Irish isolate Steinernema feltiae [strain 12(1); Boyle, 2007], Steinernema feltiae (e-nema), Steinernema carpocapsae (e-nema), and Heterorhabditis bacteriophora (Andermatt Biocontrol UK). Entomopathogenic nematodes were reared in Galleria mellonella (Lepidotera: Pyralidae), sourced commercially from Live Foods Direct (Sheffield, UK).
