“…However, at 96 h, a slight decrease was observed. The results were according to an earlier report which indicated the elevated activity of GST in response to entomopathogenic fungus Beauveria bassiana in Andrallus spinidens (Fabricius) [56]. Ding et al [38] and Jia et al [57] observed a similar trend in GST activity after exposure to fungus B. bassiana and Metarhizium anisopliae in Xylotrechus rusticus (Linnaeus) and Locusta migratoria (Linnaeus), respectively.…”

Background: In the last few decades, considerable attention has been paid to fungal endophytes as biocontrol agents, however little is known about their mode of action. This study aimed to investigate the toxic effects of an endophytic fungus Schizophyllum commune by analyzing activities of antioxidant and detoxifying enzymes as well as morphology of haemocytes using Spodoptera litura as a model. Results: Ethyl acetate extract of S. commune was fed to the larvae of S. litura using the artificial diet having 276.54 μg/ml (LC 50 of fungus) concentration for different time durations. Exposed groups revealed significant (p ≤ 0.05) increase in the activities of various enzymes viz. Catalase, Ascorbate peroxidase, Superoxide dismutase, Glutathione-S-Transferase. Furthermore, haemocytes showed various deformities like breakage in the cell membrane, cytoplasmic leakage and appearance of strumae in the treated larvae. A drastic reduction in the percentage of normal haemocytes was recorded in the treated groups with respect to control. Conclusion: The study provides important information regarding the oxidative stress causing and immunosuppressant potential of S. commune against S. litura and its considerable potential for incorporation in pest management programs.

“…While the entomopathogenic fungi had specific host insects, specifically the lepidopteran (Safitri et al 2018;Ayudya et al 2019), whereas in this study the dominant arthropods were spiders and insects of coleopteran. The entomopathogenic fungi were harmless to spiders (Yuliani 2016), Coleoptera (Ngin et al 2017), and Hemiptera (Firouzbakht et al 2015;Gholamzadeh-Chitgar et al 2017).…”

Abstract. Prabawati G, Herlinda S, Pujiastuti Y. 2019. A comparative study on the arboreal arthropod abundance of rice fields between applied with fungal bioinsecticides and abamectin in the freshwater swamp of South Sumatra, Indonesia (Study case in the main and ratoon rice fields). Biodiversitas 20: 2921-2930. Ratoon rice has been cultivated by local farmers in South Sumatra and can be a source of habitat and niches for the main rice arthropods. The study aimed to compare the abundance of arthropods between main and rationed rice field applied with fungal bioinsecticides and abamectin. This study used bioinsecticides from fungi of Beauveria bassiana, Metarhizium anisopliae, and Cordyceps militaris and control using abamectin. Arboreal arthropods sampled using a sweep net. The abundance of arthropods in the main rice tends to be higher than in ratoon. Spiders found during the two rice seasons were Araneidae, Linyphiidae, Lycosidae, Oxyopidae, Salticidae, Theridiidae, Tetragnathidae, Theridiosomatidae, while predatory insects found were Mantidae, Coenagrionidae, Staphylinidae, Anthicidae, Latridiidae, Formicidae, Coccinellidae, Coccinellidae, Tettigoniidae, Miridae, Carabidae. The fungal bioinsecticides did not reduce the predatory arthropod abundance but the abamectin caused a decrease in the abundance of all guilds. The most drastic decrease was found in web-building spiders. The movement of hunting spiders and the predatory insects of the main to ratoon rice was faster than that of web-building spiders. The existence of ratoon rice could become habitats and niches for arthropods from the main rice. For this reason, controlling the herbivore insects could use bioinsecticides derived from entomopathogenic fungi.

“…This indicated that with progressing exposure time toxicity increase, the larvae were unable to synthesize GST and eventually died. Previously Gholamzadeh-Chitgar et al (2017) indicated elevated activity of GST in response to entomopathogenic fungus B. bassiana.…”

Background: In a search for the mechanism of action of an endophytic fungus Schizophyllum commune against Spodoptera litura, the effect of its ethyl acetate extract was judged on antioxidant and detoxifying enzymes as well as on morphology of haemocytes. Results: Ethyl acetate extract of S.commune was administrated to the larvae of S.litura using artificial diet method having concentration 276.54µg/ml (LC50 of fungus). The effect on antioxidant and detoxifying enzymes (Catalase, Ascorbate peroxidase, Superoxide dismutase, Glutathione-S-Transferase) was observed using haemolymph and midgut of insect larvae for different time intervals (24, 48, 72 and 96). In additionally, haemocytes morphology was also studied using Scanning Electron Microscopy (SEM) after 96hr. In particular, to resist the toxicity, the activities of the antioxidant and detoxifying enzymes (Catalase, Ascorbate peroxidase, Superoxide dismutase, Glutathione-S-Transferase) significantly (p≤0.05) increased in both the tissues of treated larvae as compared to control. The exposed group revealed various deformities in haemocytes of S.litura like breakage in the cell membrane, cytoplasmic leakage and appearance of strumae etc. Conclusion: This study provides important information regarding the oxidative stress causing potential and immunosuppressant nature of S.commune against S.litura and elucidates the patterns of antioxidant and detoxifying enzymes activities and changes in haemocytes in the susceptible larvae.
