“…In addition to the physiological defense mechanisms composed of detoxification and antioxidant systems, in recent years, it has been reported that the gut microbiota of phytophagous insects also provides an important defense against detoxifying secondary metabolites. The gut of insects provides a suitable environment for the colonization of several microbes, which, in turn, provide many potential benefits to their host insects, including assisting in metabolism, enhancing immunity and environmental adaptability, and improving defense and detoxification [ 18 , 19 , 20 , 21 , 22 ].…”

To increase the development potential of botanical pesticides, it is necessary to expand the toxicology research on plant secondary metabolites. Herein, the Hyphantria cunea larvae were exposed to tannic acid concentrations consistent with those found in larch needles, and, subsequently, the growth and nutrient utilization, oxidative damage, and detoxification abilities in the larval midgut, as well as the changes in the gut microbiome, were analyzed. Our results revealed that tannic acid treatment significantly increased the mortality of H. cunea larvae and inhibited larval growth and food utilization. The contents of malondialdehyde and hydrogen peroxide in the larval midgut were significantly elevated in the treatment group, along with a significant decrease in the activities of antioxidant enzymes and detoxifying enzymes. However, the non-enzymatic antioxidants showed a significant increase in the tannic acid-treated larvae. From gut microbiome analysis in the treatment group, the abundance of gut microbiota related to toxin degradation and nutrient metabolism was significantly reduced, and the enrichment analysis also suggested that all pathways related to nutritional and detoxification metabolism were substantially inhibited. Taken together, tannic acid exerts toxic effects on H. cunea larvae at multiple levels and is a potential botanical pesticide for the control of H. cunea larvae.

“…Microbes of Clostridium were proved to be flavonoid-degrading bacterium ( Gupta et al, 2019 ). Parabacteroides were also found to increase with the addition of flavonoids in the gut microbiome ( Zhang et al, 2022 ). In contrast, Oscillibacter and Moraxella decreased with the addition of flavonoids in the gut microbiome ( Goulart et al, 2019 ; He et al, 2021 ; Cao et al, 2022 ).…”

Altitude affects plant growth and metabolism, but the effect of altitude on plant endophytic microorganisms is still unclear. In this study, we selected 16 Ginkgo biloba trees to study the response of leaves’ endophytes to flavonoids and altitude (from 530 m to 1,310 m). HPLC results showed that flavonoids in Ginkgo biloba leaves increased by more than 150% with attitude rising from 530 m to 1,310 m, which revealed a positive correlation with altitude. Ginkgo biloba might regulate the increased flavonoids in leaves to resist the increasing light intensity. 16S rDNA sequencing results showed that the endophytic bacterial communities of Ginkgo biloba at different altitudes significantly differed. Ginkgo leaf endophytes’ alpha diversity decreased with increasing flavonoids content and altitude. The increased flavonoids might increase the environmental pressure on endophytes and affect the endophytic community in Ginkgo biloba leaves. The bacterial network in Ginkgo biloba leaves became more complex with increasing altitude, which might be one of the strategies of leaf endophytes to cope with increasing flavonoids. Metagenomes results predicted with PICRUSt showed that the abundance of flavonoid biosynthesis and photosynthesis genes were significantly decreased with the increase of flavonoid contents. High flavonoid content in leaves appeared to inhibit microbial flavonoid synthesis. Our findings indicate that altitude can modulate microbial community structure through regulating plant metabolites, which is important to uncovering the interaction of microbes, host and the environment.

“…Serratia and Acinetobacter occupied the gut tracts of the A. germari feeding on Caesalpinia decapetala (Leguminosae) population at the genus level, and are different from the results of this study. This may be caused by the differences in feeding hosts (Zhang et al, 2021). It is still not clear where the sources of these bacteria, through environment or vertical transmission are.…”

“…Network analysis of the interactions between plant secondary compounds and bacterial species abundance has showed that Gibbsiella were significantly positively correlated with diterpenoid alkaloids and flavonoid compounds (Zhang et al, 2021). In this study, host plants lead to differences in functional abundance, because M. Pumilal and P. tomentosa have different plant secondary compounds.…”

“…The gut microbiota can mitigate the influences (Boone et al, 2013; Morales‐Jiménez et al, 2009). For example, two Apriona species share the same host niche have different gut microbiome diversity that might have contributed to the success of insects in food‐niche competition (Zhang et al, 2021). However, there are no studies regarding gut bacterial communities of A. germari when they were reared on different host plants.…”

Apriona germari is one of the most serious wood‐boring pests that cause damage to economic and landscaping trees and has adapted to a wide range of plants as diet. Gut bacteria play an important role in biology and ecology of herbivores, especially in growth and adaptation. To investigate how plant hosts shape A. germari gut microbiota, A. germari larvae were collected from Populus tomentosa and Malus pumilal, and gut microbiomes were sequenced based on 16S rDNA high‐throughput sequencing technology. A total of 853,424 high‐quality reads were obtained and clustered into 196 operational taxonomic units under a 97% similarity cutoff, which were annotated into 8 phyla, 10 classes, 21 orders, 34 families, 59 genera, and 39 species. Gibbsiella was the most dominant genus of intestinal bacteria, followed by Enterobacter and Acinetobacter. No significant difference was observed in larvae gut bacterial richness and diversity of A. germari collected from two hosts, though alpha diversity showed that the richness of gut bacteria in A. germari larvae collected on P. tomentosa was slightly higher than that in A. germari on M. pumilal, and beta diversity showed little difference between two host plants. The functional abundance analysis of the detected bacteria revealed fermentation, chemoheterotrophy, symbionts, and nitrate relative functions that highly possibly support wood‐boring beetles to feed on woody tissues. Our study provided a theoretical basis for investigating the function of intestinal symbiosis bacteria of A. germari.
