“…Consistent with our findings, Mohamed and Shaira (2023) reported that S. carpocapsae displayed greater virulence against various stages of FAW larvae compared to H. indica. Numerous studies have substantiated the variability in the efficacy of different entomopathogenic nematode species on FAW larvae and other insect pests in terms of mortality and damage caused (Rahoo et al, 2011(Rahoo et al, , 2018aFallet et al, 2022). Steinernema nematodes exhibited a high potential in controlling FAW larvae (Acharya et al, 2020).…”

The fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae), is a recent invasive pest significantly impacting maize production and food security in sub-Saharan Africa. While chemical insecticides have offered the most effective control in Ghana, their detrimental effects on human health and the environment necessitate the urgent exploration of alternative, environmentally friendly options. This study compared two entomopathogenic nematodes populations, Heterorhabditis bacteriophora and Steinernema carpocapsae, against a control group (no application) for their efficacy in managing fall armyworm on maize. In the second experiment, S. carpocapsae significantly outperformed both H. bacteriophora and the control in terms of seed weight, achieving a 12.9% increase over the former and a remarkable ninefold improvement over the latter. The first experiment, however, showed no significant difference in seed yield (59 g, 32 g, 2 g) between the two nematode treatments, S. carpocapsae demonstrated the highest yield within this group. Notably, the control group exhibited the highest degree of foliage damage (4.7; 5.0) on a 1-5 scale throughout the study period. Overall, this study demonstrates the superior efficacy of S. carpocapsae compared to H. bacteriophora in controlling fall armyworm on maize. These findings provide valuable understandings for advancing the practical application of entomopathogenic nematodes as a sustainable and eco-friendly biocontrol measure against this devastating pest, contributing to enhanced food security in sub-Saharan Africa.

“…According to Kaya and Gaugler (1993), species of EPNs from the families Steinernematidae and Heterorhabditidae are the most effective biocontrol agents for managing insect pests. EPNs are utilized as biocontrol agents to manage various insect pests such as earthworms, borers, cutworms, and pink bollworm (Poinar, 1990;Rahoo et al, 2011Rahoo et al, , 2017Rahoo et al, , 2018a. The J2 stage of nematodes, often referred to as infective juveniles, enters the host insect through natural openings such as its mouth, as well as through wounds caused by various environmental conditions (Dowds and Peters, 2002).…”

Leucinodes orbonalis is a potential pest of eggplant, commonly known as fruit and shoot borer. Owing to its devastating nature, chemical pesticides are frequently applied and insecticide pressure is significantly higher in developing nations. Keeping the current situation in mind the most effective and practical strategy for managing insect pests found in humid and subtropical environments is the bio-control. Entomopathogenic nematodes, has been utilized against many pests for their effective management. Keeping in view the biocidal potential of entomopathogenic nematodes, the current study was planned to explore the biocidal potential of Steinernema and Heterorhabditis, two significant genera of entomopathogenic nematodes against L. orbonalis. White trap extraction technique was used to isolate nematodes from several insect larvae. Four discrete concentrations of entomopathogenic nematodes viz. 60, 90, 120, and 150 infective juveniles per larvae were applied on larval stages. The virulence trial was followed by completely randomized block design. Multiple comparisons showed that among both the tested nematodes H. bacteriophora induced significant 81.33% mortality corresponding to 150 IJs/larva after 72 h of exposure as compared to S. glaseri. In the view of current research, entomopathogenic nematodes are recommended to be used in integrated pest management program for the management of insect pests.
