“…The resistance has been documented against organophosphates, carbamates and marginal synthetic pyrethroids (Visnupriya and Muthukrishnan, 2017). By using various bio-control agents, such as predators, antagonistic fungi, bacteria, viruses, and entomopathogenic nematodes and entomopathogenic fungi, many pests of various crops have been effectively managed (Reddy and Devakar, 1997;Javed et al, 2019;Rahoo et al, 2019a,b;Gulzar et al, 2020;Shehzad et al, 2021Shehzad et al, , 2022. Entomopathogenic nematodes have existed all over the world and have a variety of ecologically distinct environments.…”

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.

“…Bio-insecticides made from entomopathogenic fungi are readily available on the market, including products from the genera Beauveria sp., Cordyceps sp., Isaria sp., Lecanicillium sp., Metarhizium sp., and Nomuraea sp. ( Javed et al., 2019 ; Bara and Laing, 2020 ; Islam et al., 2021 ; Rajula et al., 2021 ; Shehzad et al., 2021 ; Shehzad et al., 2022 ; Tu et al., 2023 ). Because these entomopathogenic fungi are widespread and adaptable, they have been used successfully to eliminate insects in a wide range of habitats around the world ( Roberts and Humber, 1981 ; Scholte et al, 2004 ; Ambethgar, 2009 ; Goble et al, 2010 ; Araújo and Hughes, 2016 ; Vivekanandhan et al., 2020a ).…”

Background‘The fall armyworm, Spodoptera frugiperda’, represents a significant threat to maize production, a major staple crop in Asian countries.MethodsIn pursuit of more effective control of this insect pest, our study assessed the physiological and biochemical effects of the entomopathogenic fungus Metarhizium anisopliae against the larvae of S. frugiperda.ResultsResults revealed that, following nine days of treatment, a high concentration of conidia (1.5x107 conidia/mL-1) was toxic to all stages of larvae (second to fifth instar), resulting in 97% mortality of the second instar, 89% mortality of the third instar, 77% mortality of the fourth instar, and 72% mortality of fifth instar. All larval instars were found to have dose-dependent mortality effects. Treated S. frugiperda larvae further displayed significant physiological, morphological, and behavioral changes. Here, treated larvae displayed significantly lower levels of acetylcholinesterase, α-carboxylesterase, and β-carboxylesterase enzyme activity when compared to control groups. Treated larvae underwent an outward morphological change as the result of a decrease in the exterior cuticle of the anal papillae and a demelanization of the interior cuticle. Treated larvae also exhibited abnormal feeding behaviors as a consequence of the negative impact of conidia treatment on the neuromuscular system. Investigation into the effect of M. anisopliae on the non-target organism, the earthworm Eudrilus eugeniae, revealed that M. anisopliae conidia did not produce significant pathogenicity following three days of treatment. Furthermore, histological analysis revealed no significant effect of the entomopathogenic fungi on the gut tissue of the non-target organism.ConclusionThis study highlights the potential of M. anisopliae in the control of S. frugiperda.

“…Various management measures are employed to manage insect pests in okra, including chemical insecticides, biological control methods, synthetic insecticides, and resistance mechanisms that modify insect growth, development, and population dynamics (Mukhtar et al, 2023;Shahbaz et al, 2023). However, previous studies have indicated that using entomopathogenic fungi, either independently or in conjunction with plant extracts, has the potential to mitigate insect pest populations effectively (Javed et al, 2019;Gulzar et al, 2020;Shehzad et al, 2021Shehzad et al, , 2022. According to Jan et al (2022), synthetic insecticides have been extensively employed to manage insect infestations.…”

A field study on integrated pest management of okra insect pests was conducted at the Plant Pathology Research Institute, Ayub Agriculture Research Institute, in collaboration with the Department of Entomology, University of Agriculture Faisalabad, during the 2022 crop season. Rama Krishma, a variety of okra, was sown using the Randomized Complete Block Design with four replications and employing the drilling technique and agronomical practices. Significant differences (P0.05) in insect pest populations, namely whitefly, jassid, thrips, aphids, Helicoverpa, and spotted bollworm, were observed across various treatments. The pest populations of all these insects progressively decreased with treatment applications, and post-treatment measurements were taken 48 hours after each spray. The minimum mean populations of aphids (2.01/leaf), thrips (0.15/leaf), jassids (1.86/leaf), and spotted bollworm (2.41/plant) were recorded with the application of the biosal treatment, followed by Helicoverpa (1.25/plant) and whitefly (0.13/leaf) populations, which were observed in plots treated with tobacco extract and Chrysoperla + Trichogramma, respectively. The maximum mean populations of Formicomus antiqumus (0.55), Laius malleifer (0.17), Orius bugs (0.56), Trichogramma chilonis (Ishii) (20.41), Chrysoperla carnea (0.31), ladybird beetles (0.69), ants (0.79), and spiders (0.89) were recorded in the Chrysoperla + Trichogramma treated plots, indicating the safety of this bio-pesticide for predatory populations. Analysis of yield attributing parameters revealed that biosal-treated plots exhibited the highest values for several factors, including the maximum number of fruits per plant (19.57), number of flowers (8.75), squares (18.34), plant height (42.36 cm), and number of branches per plant (3.73). Furthermore, the cost-benefit ratios for okra plants were highest for treatments involving tobacco extract and natural enemies, with ratios of 1:16.3 and 1:10.6, respectively. The application of biosal after treatment demonstrated superior efficacy as a control approach compared to alternative treatments
