Abstract BACKGROUND Entomophagous fungi (EPF) not only directly kill insect pests, but also colonize plants and improve their resistance against pests. However, most previous research has focused on Beauveria bassiana Metarhizium anisopliae , there are few reports whether other EPF can enhance pests via endogenous colonization. Herein, an strain was isolated from diseased larvae of Spodoptera litura in a soybean field, subjected to genome‐wide sequencing at the chromosomal level. The pathogenicity isolate toward various pest insects evaluated, ability induce phytopathogens tested. RESULTS purified identified as M. rileyi designated MrS1Gz1–1. Biological assays revealed its strong five belonging Lepidoptera Hemiptera. Furthermore, inhibited growth soil‐borne plant disease caused by Sclerotinia sclerotiorum vitro . It colonized endophyte soil application, thereby inducing resistance‐related genes phytopathogen infection, it disrupted feeding selectivity S. larvae. CONCLUSION MrS1Gz1–1 potential broad‐spectrum microbial control agent that endotype. complete genome provides valuable resource for exploring host interactions. © 2024 Society Chemical Industry.

Agricultural crop productivity relies on the application of chemical pesticides to reduce pest and pathogen damage. However, also pose a range ecological, environmental economic penalties. This includes development pesticide resistance by insect pests pathogens, rendering less effective. Alternative sustainable protection tools should therefore be considered. Semiochemicals are signalling molecules produced organisms, including plants, microbes, animals, which cause behavioural or developmental changes in receiving organisms. Manipulating semiochemicals could provide more approach management pathogens across crops. Here, we review role interaction between insects examples how they have been applied agricultural systems. We highlight future research priorities considered for credible alternatives pesticides.

Cereal aphids, Sitobion avenae and Rhopalosiphum padi, cause severe yield loss in wheat crops as a consequence of direct feeding damage acting vectors for Barley Yellow Dwarf Virus (BYDV). Insecticides have commonly been used to control these pests, but the advent insecticide resistance spreading across aphid populations push reduce use means that new approaches are required. Wheat varieties with metabolite-based identified, suggesting they could be developed an alternative insecticides. Resistance induced by natural products (metabolites) include volatile organic compound-mediated (antixenotic) development-modifying (antibiotic) processes. Full characterisation mechanisms is still required, associated challenges, such influence biotic abiotic interactions, need addressed prior their implementation into integrated pest management (IPM) or engineered modern elite wheats.

Abstract Sensory neuron membrane protein ( SNMP ) gene play a crucial role in insect chemosensory systems. However, the of host searching behaviour Rhopalosiphum padi (Hemiptera: Aphididae), highly destructive pest cereal crops, has not been clearly understood. Our previous research shown that three wheat volatile organic compounds (VOCs) – (E)-2-hexenol, linalool, and octanal can attract R. , but involvement aphid’s olfactory response to these VOCs be elucidated. In this study, only one was cloned characterised from . The results revealed belongs SNMP1 subfamily named RpadSNMP1. RpadSNMP11 predominantly expressed antennae aphid, with significantly higher expression levels observed winged forms, indicating it is involved responses padi. RpadSNMP1 up-regulated following starvation, showed decreasing trend after 24 h aphid feeding. Functional analysis through knockdown demonstrated significant decrease ’s ability search for plants. residence time injected ds shortened linalool according four-arm olfactometer, mediating VOCs. Molecular docking suggested potential binding interactions between Overall, findings provided evidence plant lay foundation developing new methods control pest.

Insect communities consist of species from several trophic levels that have to forage for suitable resources among and within larger patches nonresources. To locate their resources, insects use diverse stimuli, including olfactory, visual, acoustic, tactile gustatory cues. While most research has focused on cues derived plants other insects, there is mounting evidence also respond volatile organic compounds (VOCs) emitted by microorganisms. However, date little known about how the olfactory response across different affected bacterial VOCs. In this study, we used Y-tube bioassays chemical analysis VOCs assess bacteria affect same levels. Experiments were performed using two aphid (Amphorophora idaei Börner Myzus persicae var. nicotianae Blackman), three primary parasitoid (Aphidius colemani Viereck, A. ervi Haliday, matricariae Viereck), hyperparasitoid (Asaphes suspensus Nees Dendrocerus aphidum Rondani). Olfactory responses evaluated strains (Bacillus pumilus ST18.16/133, Curtobacterium sp. ST18.16/085, Staphylococcus saprophyticus ST18.16/160) isolated habitat insects. Results revealed all responded volatiles, but varied between All produced set compounds, often in relative concentrations. For 11 these volatiles found contrasting correlations concentration behavior parasitoids hyperparasitoids.

Biological control using plant-beneficial fungi has gained considerable interest as a sustainable method for pest management, by priming the plant enhanced defense against pathogens and insect herbivores. However, despite promising outcomes, little is known about how different fungal strains mediate these beneficial effects. In this study, we evaluated whether inoculation of tomato seeds with Beauveria bassiana ARSEF 3097, Metarhizium brunneum 1095 Trichoderma harzianum T22 affected plant’s volatile organic compound (VOC) profile host-choice behavior Nesidiocoris tenuis , an emerging species in NW-European cultivation, related zoophytophagous biocontrol agent Macrolophus pygmaeus . Results indicated that did not significantly alter VOC composition plants. two-choice cage assay where female insects were given option to select between plants fungus-inoculated plants, N. preferred over M. -inoculated Nearly 72% all individuals tested chose treatment. other combinations tested, no significant differences found none insects. We conclude had limited effects on observation was deterred from crop when inoculated attracted non-inoculated may provide new opportunities future based push-pull strategy.

Plants and insect herbivores are two of the most diverse multicellular groups in world, both strongly influenced by interactions with belowground soil microbiome. Effects reciprocal rapid evolution on ecological between plants have been repeatedly demonstrated, but it is unknown if (and how) microbiome could mediate these eco‐evolutionary processes a shared host plant. We tested role plant‐beneficial bacterium Acidovorax radicis altering different aphid genotypes ( Sitobion avenae , Sickte Fescue) feeding barley Hordeum vulgare . measured fecundity, longevity population growth reared separately or together (population mixture) three varieties that were inoculated without A. Results showed across all plant increased suppressed populations via reduced fecundity. The strength effect was dependent genotype variety, while direction altered mixture. Using Lotka–Volterra modelling, we demonstrated inoculation decreased rates for competitiveness one against other. In general, presence Fescue became more inhibitory aphids, aphids facilitated aphids. Our work demonstrates rhizosphere microbiomes exert community‐level influences mediating plants. By competitive interaction outcomes among thus impacting such as evolution, microbes contribute to short‐ long‐term structure functioning terrestrial habitats.
