Mycoviruses can alter the biological characteristics of host fungi, including change virulence or pathogenicity phytopathogens and entomopathogenic fungi (EPF). However, most studies on mycoviruses found in EPF have focused effects viruses towards insect pests, with relatively few reports to regard plant disease resistance hosts.

Beauveria bassiana and Metarhizium rileyi are extensively utilized to investigate fungal pathogenic mechanisms develop biological control agents. Notwithstanding, notable distinctions exist in their pathogenicity against the same host insect. This study aimed elucidate differences between M. B. by examining impact of various ratios strain AJS91881 SXBN200920 on fifth instar larvae Spodoptera litura, focusing early infection stages intestinal microbial community structure. The lethal time 50 (LT50) for was significantly lower than that rileyi, indicating greater efficacy. Survival analyses mixed groups (ratios 1:9, 1:1, 9:1 bassiana) consistently demonstrated higher virulence bassiana. Intestinal diversity analysis revealed a significant increase Achromobacter Pseudomonas infected with whereas Weissella notably those Additionally, shifts genera abundances were observed across all groups. KEGG pathway enrichment indicated employ distinct strategies during stages. In vitro tests confirmed superior growth stress resistance compared but antifungal ability better conclusion, our findings provide preliminary insights into differential behaviors S. litura larvae, enhancing understanding informing pest agriculture forestry.

Abstract BACKGROUND Aphids are important agricultural and forestry pests that not only directly harm plants, but also transmit various plant viruses. Biological control, including the use of entomopathogenic fungi (EPFs) predatory natural enemies, can effectively control aphids. However, there few reports on combined enemies carrying EPF to enhance efficiency aphid control. RESULTS In present study, we evaluated compatibility five strains with adults Harlequin ladybird ( Harmonia axyridis ). The pathogenicity, impact function, fertility H. were assessed as indicators, predator was evaluated. results showed four did exhibit direct or indirect pathogenicity toward . Additionally, they significantly affect survival rate, predation egg production hatching rate adult feeding Acyrthosiphon pisum lower than group after 0 h starvation, no significant differences observed following 24 48 starvation. Under semi‐field conditions, release had been treated previously Metarhizium rileyi resulted in a higher A. Rhopalosiphum maidis Day 4 mortality rates 83.33% 98.35%, respectively. comparison, treatment exhibited 46.22% 84.16% mortality, respectively, whereas M. experienced 10.67% 61.06%, CONCLUSION Four isolates effect axyridis. reproduction axyridis, yet conidia two species aphids compared each type enemy alone.

Fusarium citri has been historically recognized as a phytopathogen but never an entomophagous fungus (EPF) with plant endogeneity. In the present study, F. strain, FcS1GZL-1, was isolated and identified from diseased Spodoptera litura larvae in soybean field. The pathogenicity antagonistic activity of FcS1GZL-1 against five insect pests were assessed, well its ability to colonize plants via root irrigation, induced resistance phytopathogens also measured. expression related genes analyzed using real-time RT-PCR. According results, strain could not only kill high inhibited growth vitro. Furthermore, repel pest feeding enhance through endophytic customization following which upregulated 12 jasmonic acid, salicylic ethylene, pathogen-related defense pathways roots. Herein, we first documented case naturally infecting insects, dual role controlling phytopathogens, promising biocontrol applications.
