“…Organic matter-rich soils are known to have high cation exchange capacities, which in turn may adsorb and retain a large amount of EPF spores (Quesada-Moraga et al 2007;Sharma et al 2018b). In addition, organic fertilizers could serve as a growth substrate for EPF mycelium (Klingen et al 2002;Noble et al 2018). Organic fertilizers also increase the abundance of soil-dwelling arthropods that are potential hosts for EPF or that act as vectors in spreading and transmitting EPF spores (Ali-Shtayeh et al 2002;Thiele-Bruhn et al 2012;Anslan et al 2018;Lin et al 2019).…”

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.

Parametarhizium (Clavicipitaceae) gen. nov. With Two New Species as a Potential Biocontrol Agent Isolated From Forest Litters in Northeast China

A novel genus Parametarhizium with two new entomopathogenic species, Parametarhizium changbaiense and Parametarhizium hingganense, was introduced based on their morphological characteristics and a multigene phylogenetic analysis, which were isolated from the forest litters collected in Northeast China. To infer their phylogenetic relationships, a six-gene dataset consisting of DNA fragments of [nuclear small subunit rDNA (SSU) + LSU + TUB + TEF + RPB1 + RPB2] was used for phylogenetic analysis, including 105 related fungi. The new genus Parametarhizium formed a monophyletic clade basal to Metarhizium and its related genera (formerly Metarhizium sensu lato). Parametarhizium can be morphologically distinguished from related genera by the combination of the following characteristics: formation of white to yellow colonies on different media, candelabrum-like arrangement of cylindrical or obpyriform phialides, and small subglobose to ellipsoidal conidia. Both P. hingganense and P. changbaiense exhibited anti-insect activities against three farmland pests Monolepta hieroglyphica, Callosobruchus chinensis, and Rhopalosiphum maidis. This is the first report of entomopathogenic fungi exhibiting the anti-insect activity against Mo. hieroglyphica.

“…Conidia were sprayed onto or drenched into the soil or plant growing media before introducing larvae or adults onto the treated surface under laboratory conditions. Moderate (60–80%) to high (>80%) mortality of the weevils was observed [ 236 , 243 , 244 , 245 , 246 , 247 , 248 , 249 , 250 , 251 , 252 , 253 , 254 ]. The commercial strains/products Met52 ® and Naturalis ® showed strong and consistent control of weevils and caused high (>80%) levels of mortality [ 248 , 250 , 254 ].…”

“…Shapiro-Ilan et al [ 218 , 225 ] reported the number of conidia recovered from topsoil dropped to almost zero 7 weeks after an EPF application in the field. To minimise rapid conidial degradation in the field, several studies have recommended that EPF should be incorporated with pasteurised potting media (such as peat-based and bark-based potting media) for at least one week before use [ 248 , 250 ]. This allows the EPF to adjust to the media and grow in controlled conditions with good moisture levels and nutrients before being used in the field.…”

“…The application of EPF incorporated into plant growing media around and below crops to produce a “contamination layer” or “infective zone” has been shown to provide long-term control of adult and larval weevils. Incorporating EPF with pasteurised organic fertilizers, compost or growing media [ 248 , 249 , 250 ] in combination with zero-tillage [ 280 , 281 ] may improve not just the abundance, but also the persistence of EPF in the soil. This approach may help compensate for the problems associated with the limited durability and infectivity of EPF in horticultural crops.…”

Weevils are significant pests of horticultural crops and are largely managed with insecticides. In response to concerns about negative impacts of synthetic insecticides on humans and the environment, entomopathogenic fungi (EPF) have been developed as an alternative method of control, and as such appear to be “ready-made” components of integrated pest management (IPM) programs. As the success of pest control requires a thorough knowledge of the biology of the pests, this review summarises our current knowledge of weevil biology on nut trees, fruit crops, plant storage roots, and palm trees. In addition, three groups of life cycles are defined based on weevil developmental habitats, and together with information from studies of EPF activity on these groups, we discuss the tactics for integrating EPF into IPM programs. Finally, we highlight the gaps in the research required to optimise the performance of EPF and provide recommendations for the improvement of EPF efficacy for the management of key weevils of horticultural crops.
