“…Therefore, all data were then submitted to a oneway analysis of variance (ANOVA). In addition, the mortality data were not subjected to Abbot's formula of corrected mortality since the mean mortality in control was less than 5% (Puspitarini, Fernando, Sianturi, et al, 2022). The means were compared by Tukey's multiple comparison tests at P < 0.05.…”

“…The suspension was centrifuged at 3,000 rpm for 5 minutes to separate the conidia from the mycelium. The obtained conidia pellet was then mixed with 5 ml of distilled water, and the conidia density was calculated using a haemocytometer with the aid of a compound microscope (Puspitarini, Fernando, Sianturi, et al, 2022). Conidia density is calculated using the Eqn 1.…”

Entomopathogenic fungi (EPF) can be an eco-friendly alternative to control pests. To produce large-scale EPF requires underused economical substrates containing high carbon and nitrogen; hence the production could be cost-effective. This study investigates the effects of organic agricultural waste, i.e., rice bran, rice husks, tea dregs, and wheat bran enriched with cricket powder as culture media on the mycelial growth, sporulation, and conidia viability of Beauveria bassiana and the fungal pathogenicity towards Spodoptera litura larvae. For each type of medium, five independent cultures of B. bassiana are treated as replications. B. bassiana grown on a PDA medium is treated as a control. This study shows that rice bran enriched with cricket powder became the most suitable waste medium to support the mass production of virulent B. bassiana. Therefore, rice bran media enriched with cricket powder can be used as an appropriate medium for the mass production of B. bassiana.

“…The data were then subjected to analysis of variance (ANOVA) followed by Duncan's multiple range test (DMRT). The data on mortality of S. litura were not corrected by Abbott's formula as the larval mortality in the control groups was less than 5% (WHO 2016; Puspitarini et al 2021b). In addition, Pearson's correlation was used to determine the relationship between conidial viability and mortality of S. litura larvae.…”

Abstract. Afandhi A, Choliq FA, Fernando I, Marpaung YMAN, Setiawan Y. 2022. Occurrence of soil-inhabiting entomopathogenic fungi within a conventional and organic farm and their virulence against Spodoptera litura. Biodiversitas 23: 1172-1180. Naturally occurring entomopathogenic fungi (EPF) are important components in agroecosystems as they serve as biocontrol agents of insect and mite pests. However, some cultivation practices may have deleterious effects on EPF. In this study, the occurrence of soil-inhabiting EPF was investigated between a conventional and organic farm. EPF was baited using Tenebrio molitor larvae, and their virulence was tested against Spodoptera litura larvae. The results showed a higher occurrence of EPF in the organic farm than the conventional farm, with Aspergillus sp., Beauveria sp., and Gliocladium sp. were exclusively found in organic soils. Among the twenty-five EPF isolates obtained, only four isolates were avirulent against S. litura larvae. Isolates belonging to Beauveria, Metarhizium, and Paecilomyces genera caused high mortality of S. litura larvae ranging from 40 to 65%. There was a significant positive relationship between the conidial viability of EPF and larval mortality. Since virulent isolates were found in conventional soils, efforts in preserving EPF prevalence are needed through the implementation of appropriate cultivation practices. The synthetic agrochemicals exclusion, organic fertilizers application, and crop rotation practiced in the organic farm should be integrated into any other agroecosystems as a form of conservation biological control strategies to strengthen the pest control service provided by EPF.
