Abstract Gut microbiota are important in the adaptation of phytophagous insects to their plant hosts. However, interaction between gut microbiomes and pioneering populations invasive during new hosts, particularly initial phases invasion, has been less studied. We studied contribution microbiome host globally recognized pest, Hyphantria cunea, as it expands its range into southern China. The population H. cunea shows effective Metasequoia glyptostroboides exhibits greater larval survival on...

The camellia weevil (CW [Curculio chinensis]) is a notorious host-specific predator of the seeds Camellia species in China, causing seed losses up to 60%. capable overcoming host tree chemical defenses, while mechanisms how these beetles contend with toxic compounds are still unknown. Here, we examined interaction between gut microbes CW and chemistry found that beetle-associated bacterial symbionts mediate tea saponin degradation. We demonstrate microbial community profile was significantly...

The gut microbiome plays an important role in a host’s development and adaption to its dietary niche. In this study, group of bamboo-feeding insects are used explore the potential microbiota convergent adaptation extreme diet specialization. Specifically, using 16S rRNA marker Illumina sequencing platform, we profiled microbial communities 76 samples collected from nine insects, including both hemimetabolous (Orthoptera Hemiptera) holometabolous (Coleoptera Lepidoptera) species, which...

Abstract Patterns and elevational controls on the response of soil organic matter (SOM) decomposition to temperature in alpine forest soils are critical efforts quantify regional carbon cycle–climate feedback, but not well known. Here, we report rates SOM ( R S ) sensitivity Q 10 determined a short‐term laboratory incubation with gradual warming from 5 29°C different elevations Qilian Mountains, China (2600, 2800, 3000, 3200 m). The results showed significantly increased increasing elevation...

ABSTRACT Root rot in Camellia oleifera complicates the development of targeted control measures owing to its complex aetiology. Although breeding resistant varieties C. presents a promising solution, research into cultivation strategies and potential resistance mechanisms against root remains limited. In this study, we investigated six cultivars that exhibit varying levels rot. We conducted transcriptome analysis, measurements soil physicochemical properties an analysis fungal microbiome...

The number of 360 individuals with an average initial weight 87.8 ± 0.04 g was fed six diets containing graded levels choline at 8.1 (control group), 602.5, 1119.0, 1511.5, 1970.0 and 4029.0 mg kg−1 diet, respectively, to investigate the effects dietary on growth performance, lipid deposition hepatic transport for grouper, Epinephelus coioides. Dietary methionine estimated be 10.02 kg−1, less than requirement (13.10 kg−1). results 10-week study period indicated that best values specific rate...

Plant secondary metabolites (PSMs) can affect the structures and functions of soil microbiomes. However, core bacteria associated with PSMs, their corresponding have not been explored extensively. In this study, physicochemical properties, tea saponin (TS) contents, microbial community compositions, different-age Camellia oleifera plantation soils from representative regions were analyzed. We evaluated effects age increase on PSM accumulation, subsequent consequences Plantation ages...

Switching to a new host plant is driving force for divergence and speciation in herbivorous insects. This process of incorporating novel into the diet may require number adaptations insect herbivores that allow them consume tissue contain toxic secondary chemicals. As result, insects are predicted have evolved efficient ways detoxify major defences increase fitness by either relying on their own genomes or recruiting other organisms such as microbial gut symbionts. In present study we used...

Fast-growing bamboo may be a source of high-quality cellulose with the potential to contribute energy sustainability, if an efficient and low-cost solution decomposition can developed. This study compared gut microbiomes rhinoceros beetle (Trypoxylus dichotomus) feeding on wood fiber. The results revealed that diet has distinctive effect microbial composition in midgut, including its most abundant microorganisms fermentation chemoheterotroph pathways. After identifying 13 bacterial isolates,...

Beneficial gut bacteria can enhance herbivorous arthropod adaptation to plant secondary compounds (PSMs), and specialist herbivores provide excellent examples of this. Tea saponin (TS) Camellia oleifera is triterpenoids toxic seed-feeding weevil pest, Curculio chinensis (CW). Previous studies disclosed that Acinetobacter, which was specific enriched in the CW's gut, involved helping CW evade TS toxicity C. oleifera. However, it still not clear whether Acinetobacter associated with other...

Abstract The Asian flea beetles Altica cirsicola , fragariae and viridicyanea are broadly sympatric morphologically highly similar but feed on distantly related host plants. They have been suggested as a model for ecological speciation studies. However, their phylogeny species limits remain uncertain. In this study, we added mitochondrial genomes from multiple individuals of each to the growing database. Phylogenetic analyses based 15 genes showed clear interspecific divergences A. other...

Abstract Complete mitochondrial genomes contain large and diverse datasets for species delineation. To better understand the divergence of two morphologically indistinguishable weevil in Curculionini, we first sequenced compared their complete genomes. The Curculio chinensis sp. were 19,713 bp with an A + T content 76.61% 19,216 76.85%, respectively. All 37 typical genes determined both species. 13 protein sequences shared high homology (about 90%) except ATP8 (73.08%). differences secondary...

Abstract The camellia weevil, Curculio chinensis (Coleoptera: Curculionidae), is a host‐specific parasite of Camellia seeds that causes huge economic losses in China. Despite its impact, little known about the species’ genetic structure and current distribution status, which are important to provide critical insights into establishing control strategy for this pest. Here, diversity phylogenetic C. were inferred using sequences COI EF1‐α among different geographical populations. Twenty‐two...
