Ingested fungal enzymes are responsible for cellulose digestion in the xylophagous larvae of four species ofcerambycid beetles from four different subfamilies: Bellamira scalaris (Lepturinae), Graphisurusfasciatus (Lamiinae), Orthosoma brunneum (Prioninae) and Parandra brunnea (Parandrinae). When the larvae are maintained on their normal diets of fungus-infected wood, their midgut fluids are active against microcrystalline cellulose, and they are able to digest $^{14}C-cellulose$. By contrast… Expand
Comparative aspects of plant cell wall digestion in insects
TLDR
While the bulk of the plant lignin is not significantly degraded under the conditions characteristic of gut contents of herbivores, some groups of insects are thought to be able to digest a part of this non-carbohydrate polymer. Expand
Characterization of the proteases in the midgut of the xylophagous larvae of Oemona hirta (Coleoptera: Cerambycidae)
TLDR
Investigation of the protein digestive capability of the larvae of the longhorn beetle confirmed a serine protease‐based digestive system similar to earlier reports of sapwood‐feeding Cerambycids and control of these insect pests using protease inhibitors is discussed. Expand
Analysis of gut bacterial diversity and exploration of cellulose-degrading bacteria in xylophagous insects
TLDR
Gut bacterial communities in xylophagous insects were analyzed using the pyrosequencing of 16S rRNA genes for their potential biotechnological applications in lignocelluloses degradation showed that operational taxonomic units (OTUs), species richness and diversity index were higher in the hindgut than in the midgut of all insect samples analyzed.

Effect of Host Tree Species on Cellulase Activity and Bacterial Community Composition in the Gut of Larval Asian Longhorned Beetle
TLDR
Results show that the host tree can impact both gut microbial community complexity and cellulase activity in A. glabripennis, and this community can be extremely variable when reared in different host trees. Expand
Symbiosis With Fungi
TLDR
To reconcile the conflicting evidence on possible enzyme acquisition from the fungus by the termite, it is proposed that symbiosis in the Macrotermitinae shows evolutionary diversification, with some species of fungus producing a range of enzymes according to substrate and environmental conditions (generalists) and yet others which produce little, if any, enzyme for termite use. Expand
The evolution of cellulose digestion in insects
TLDR
It is proposed that non-cellulolytic omnivorous scavengers and detritivores may be preadapted to evolve symbiont-mediated cellulolytic mechanisms because of the prevalence of mutualistic associations between such species and the microorganisms that normally reside in their hindguts. Expand
Proteomic Analysis of Fusarium solani Isolated from the Asian Longhorned Beetle, Anoplophora glabripennis
TLDR
Assessment of a gut-derived fungal isolate inoculated onto a wood-based substrate and shotgun proteomics using Multidimensional Protein Identification Technology suggests that this isolate has the endogenous potential to degrade lignocellulose and extract nutrients from woody tissue. Expand
Biofilm Improves Isopod Growth Independent of the Dietary Cellulose Content
TLDR
It is proposed that it is the biofilm community that determines the quality of plant diet in terrestrial isopods and potentially also in other detrital plant feeders. Expand
Action of the saproxylic scarab larva Cetonia aurataeformis (Coleoptera: Scarabaeoidea: Cetoniidae) on woody substrates
TLDR
The main conclusion is that the action of cetonid larvae on woody substrates could facilitate their use by other saproxylic organisms in natural ecosystems. Expand
Effects of diet type, developmental stage, and gut compartment in the gut bacterial communities of two Cerambycidae species (Coleoptera)
TLDR
The results from this study suggest that diet was the main determinant for gut bacterial community composition in the two beetle species reared with host tree logs and artificial diets as food sources. Expand

TLDR
It is proposed that a strategy of resource utilization based upon the acquisition of digestive enzymes which expand the range of natural substrates suitable for exploitation as nutrient sources may be a general one. Expand
Purification of three cellulases from the xylophageous larvae of Ergates faber (Coleoptera:Cerambycidae)
TLDR
Three different homogeneous cellulases were isolated by ultrogel chromatography and preparative electrophoresis from the gut of larvae of Ergates faber (Coleoptera:Cerambycidae), finding that during the early phases of reaction the three cellulases can act synergically. Expand
Cellulose Digestion in the Midgut of the Fungus-Growing Termite Macrotermes natalensis: The Role of Acquired Digestive Enzymes
TLDR
It is suggested that the involvement of acquired digestive enzymes could serve as the basis for a general strategy of resource utilization and that the acquisition of digestive enzymes may be a widespread phenomenon among mycophagous invertebrates. Expand
Cellulose digestion in insects
TLDR
A process in which ingested cellulolytic bacteria proliferate in one region of the gut at the expense of ingested cellulose, only to be digested and assimilated in a more posterior section, is a fourth possible mechanism by which insects might accomplish the digestion of cellulose with the help of microorganisms. Expand
Ecology of microbial cellulose degradation
TLDR
The gain of the cycling process is the capture of solar energy, which is then used by living cells for growth and maintenance, and the carbon cycle is formed. Expand
