Microbe–microbe interactions within a host drive shifts in the host’s microbiota composition, profoundly influencing physiology, ecology, and evolution. Among these microbes, maternally inherited endosymbiont Wolbachia is widespread invasive pest Liriomyza huidorbrensis (Diptera: Agromyzidae). However, its influence on remains largely unexplored. In study presented herein, we investigated bacterial communities of wLhui-infected (wLhui+) -uninfected lines (wLhui−) L. using 16S rRNA gene high-throughput sequencing. For both leaf-miner lines, Bacteroidota was dominant phylum (relative abundance: 59.18%), followed by Pseudomonadota (36.63%), Actinomycetota (2.42%), Bacillota (0.93%). We found no significant differences alpha-diversity indices between wLhui+ wLhui− (p > 0.05). principal coordinates analysis revealed composition (PERMANOVA: p < 0.001), explaining 76.70% variance composition. Correlation network identified robust negative positive associations several genera, suggesting that shapes microbial through competitive or cooperative with specific taxa. Overall, our suggests plays key role shaping microbiome, potentially affecting fitness.

Mounting evidence indicates that symbionts play a beneficial role through secondary metabolic compounds and various chemical processes in host adaptation to adversity, particularly herbivorous insects whose survival is severely threatened by insecticides or metabolite stress. Despite extensive research on insect symbionts, the spread of these correlation with phenotypes limit our ability predict manage adaptive capabilities populations changing environments. In this review, we propose concept "Mobile Resistance Elements (MRE)" describe dynamic adaptable nature resistance-related can be transmitted between hosts. These elements encompass both themselves associated traits they confer their hosts, such as enhanced resilience environmental stressors, toxins, pathogens. The mobility resistance traits, facilitated transmission modes─including vertical horizontal pathways─allows susceptible acquire phenotypes. By weaving together threads how shape adaptability strategies, underscores potential for act agents rapid adaptation, enabling pest thrive environments presenting challenges opportunities management strategies.

Silicon-induced responses play a key role in plant defense against herbivory, though the underlying mechanisms remain underexplored. In this study, we examined how mesoporous silica nanoparticles (MSNs) affect tomato ( Solanum lycopersicum ) an invasive and highly destructive lepidopteran herbivore, pinworm (TPW), Phthorimaea absoluta . plants supplemented with MSN, prior exposure to TPW oviposition shifted subsequent egg-laying from preference for leaves even distribution between stems leaves. This shift was not observed nonsilicon-supplemented plants. Prolonged triggered pigmentation basal cells of type I glandular trichomes on silicon-supplemented Chemical analysis by coupled gas chromatography-mass spectrometry revealed that pigmented trichome rich soluble sugars (sucrose l -arabinose) waxes, dominated saturated hydrocarbon tetracosane. Bioassays crude extract three-component sugar–wax blend replicated caterpillar response trichome, while individual components produced variable effects. While -arabinose alone effects blend, sucrose increased feeding survival, tetracosane caused highest mortality. Additionally, these treatments altered gut microbiota composition influenced frass volatiles, which attracted natural enemies, Nesidiocoris tenuis (predator) Neochrysocharis formosa (parasitoid). Our findings suggest silicon supplementation increases through oviposition-induced responses, promotes recruitment enemies.

This review provides an in-depth examination of the intricate interactions between plant metabolites and digestive antioxidative enzymes in insects, highlighting their essential roles shaping insect herbivory adaptation strategies. Plants have evolved a diverse arsenal secondary to defend against herbivorous which, response, developed sophisticated adaptations overcome these defenses efficiently exploit resources. We outline importance enzymes, such as proteases amylases, which allow insects break down complex compounds access vital nutrients. Additionally, focuses on midgut, including superoxide dismutase catalase, play crucial role mitigating oxidative stress generated during digestion other metabolic processes. Synthesizing findings from various studies, this also considers how environmental factors, heavy metal exposure temperature changes, influence enzymes’ activity levels. It highlights dual function detoxifying harmful plant-derived while preserving cellular stability. The implications biochemical for pest management are discussed, with emphasis potential developing biopesticides that target specific enzymatic pathways disrupt feeding growth. By elucidating mechanisms underlie plant-insect interactions, enhances our understanding co-evolutionary dynamics offers insights into sustainable agricultural practices could leverage effective control. Finally, proposes future research directions aimed at identifying novel enzyme-modulating properties exploring ecological impacts enzyme-targeted approaches.
