Understanding air microbial content, especially in highly polluted urban areas, is crucial for assessing its effect on human health and ecosystems. In this context, the impact of gaseous pollutants aerobiome remains inconclusive due to a lack studies separating factor from other contaminants or environmental factors. study, we aimed experimentally assess influence contrasting concentrations atmospheric as isolated variables composition aerobiome. Our study sites were Air Quality Index (AQI) Metropolitan Region Chile, where nitric oxide (NO) was significantly lower at low-AQI site than high-AQI site, while ozone (O3) higher. Cultivable communities exposed their own those characterized using high-throughput sequencing (HTS), which allowed comparisons between entire cultivable communities. The results showed increased alpha diversity bacterial fungal compared site. Beta compositional hierarchical clustering analyses revealed clear separation based NO O3 concentrations. At phylum level, four three phyla identified, revealing an over-representation Actinobacteriota Basidiomycota samples transferred Proteobacteria more abundant community maintained functional imputed functions over-represented only affected both conditions.

Abstract With the continuous growth of global agricultural production, pest control has become a critical factor in ensuring crop health and increasing output. In view safety food ecology, development more environmentally friendly sustainable approaches for management is desirable. All insects are colonized by microorganisms on insect cuticle or body. These resident can promote fitness, impact transmission plant pathogens, protect against natural enemies adverse environments. Thus, insect‒microbe symbiosis-based strategies provide new avenue pests their transmitted pathogens. This review summarizes developments field based symbiosis proposes future directions. First, we introduce symbiotic functions. discusses application insect-microbe strategies, including native engineered symbionts, utilization bioactive substances produced microorganisms, an disruption strategy. Despite great potential this novel pest-control strategy, many challenges remain, such as stability bacteria, environmental adaptability, non-target organisms. Finally, concludes suggesting directions, improving targeting specificity enhancing developing integrated that combine means with others to achieve effective control.

Abstract Citrus greening (Huanglongbing) disease has serious impacts on citrus production. Field monitoring of the Asian psyllid Diaphorina citri (Hemiptera: Psyllidae), a vector disease, is essential to prevent invasion and spread this disease. This study reports new method for determining presence D. traces contact with host plants by collecting leaves from survey area detecting environmental DNA (eDNA) derived . The results show that applied can be determined. As ‐derived eDNA contained in solutions history , we succeeded not only genes conserved mitochondria but also symbiont organisms consisting Wolbachia phage, Candidatus Carsonella sp., Profftella sp. could detected even after 10 min still 6 months contact. technology potential trace their without individual detection expected greatly contribute early warning future.

Chelonus formosanus is a parasitic wasp capable of parasitizing various Noctuidae pests, including the highly invasive Spodoptera frugiperda, and it demonstrates strong pest control potential. Both egg larval stages primarily occur within host organism, total developmental time from to adult approximately 19.62 days. To investigate microbial communities at different stages, we performed 16S rDNA sequencing (V1–V9 region) using PacBio identified 404 bacterial species belonging 61 classes, 116 orders, 182 families, 308 genera across larval, pupal, female, male stages. Bacterial diversity richness varied with Enterobacter Enterococcus dominating in larvae pupae Pseudomonas emerging as dominant female adults. In contrast, adults predominantly resided Ralstonia Achromobacter. The predicted functions bacteria C. are marked by high abundance metabolic pathways. This study provides comprehensive understanding morphology contributes practical pests. Additionally, our findings preliminarily characterized community laying groundwork for its functional study.

Abstract Spodoptera frugiperda (fall armyworm) poses a substantial risk to crops worldwide, resulting in considerable economic damage. The gut microbiota of insects plays crucial roles digestion, nutrition, immunity, growth and, sometimes, the degradation insecticides. current study examines effect synthetic insecticides on microbiome third instar S. larvae using both culture‐dependent techniques and 16S rRNA gene sequencing for bacterial community profiling diversity analysis. In untreated larvae, approach revealed diverse dominated by phyla Firmicutes, Proteobacteria Bacteroidota, with key genera including Bacteroides , Faecalibacterium Pelomonas . parallel, 323 strains were isolated assigned orders Bacillales, Burkholderiales, Enterobacterales, Flavobacteriales, Lactobacillales, Micrococcales, Neisseriaies, Pseudomonadales, Sphingobacteriales Xanthomonadales. prevailing culturable species included Serratia marcescens Klebsiella variicola Enterobacter quasiroggenkampii Treatment sublethal concentrations three (broflanilide, spinosad indoxacarb) caused significant changes composition. Treated showed shift towards increased abundance decreased Firmicutes. Specifically, Acinetobacter Rhodococcus dominant treated samples. Functional predictions highlighted metabolic versatility involving nutrient processing, immune response, detoxification, xenobiotic metabolism, stress suggesting microbial adaptation insecticide exposure. Network correlation analysis disrupted interactions altered structures under treatment. These findings enhance our understanding how impact may inform future strategies managing pest resistance through microbiome‐based approaches.
