“…It was observed that the antibiotic-fed silkworm larvae showed a significant amount of Firmicutes and Actinobacteria but a minor amount of Proteobacteria . Additionally, the antibiotic-treated silkworms seemed to be more vulnerable to CPF, supporting the hypothesis that the gut microbiota plays a crucial role in pesticide resistance [ 57 ]. Though, other authors did not demonstrate a shift in a mosquito gut microbial community, despite the pesticide-degrading microbiota resulting enriched [ 58 ].…”

In recent years, new targets have been included between the health outcomes induced by pesticide exposure. The gastrointestinal tract is a key physical and biological barrier and it represents a primary site of exposure to toxic agents. Recently, the intestinal microbiota has emerged as a notable factor regulating pesticides’ toxicity. However, the specific mechanisms related to this interaction are not well known. In this review, we discuss the influence of pesticide exposure on the gut microbiota, discussing the factors influencing gut microbial diversity, and we summarize the updated literature. In conclusion, more studies are needed to clarify the host–microbial relationship concerning pesticide exposure and to define new prevention interventions, such as the identification of biomarkers of mucosal barrier function.

“…virescens larvae, indicating possible shifts in microbial community profiles upon cultivation of the insect in the laboratory [59] . Previous studies also reported a great diversity of metabolic capabilities represented in the total gene pool of the gut microbiota in the silkworm [41] , [60] . The functions of the major gut colonizers deserve further study in this model organism.…”

“…Smith, 1797) larvae are highly effective in degrading deltamethrin and spinosyn 45 . Finally, the bacteria Stenotrophomonas maltophilia and Enterococcus mundtii, isolated from the intestine of the silkworm Bombyx mori (Linnaeus, 1758) were shown to influence resistance to the organophosphate insecticides 46,47 . Similarly in our study, the gut bacterial communities of the insects fed with leaves of S. lycopersicum shared 14 common genera with those detected on the leaves of S. lycopersicum.…”

Insects are known plant pests, and some of them such as Trichoplusia ni feed on a variety of crops. In this study, Trichoplusia ni was fed distinct diets of leaves of Arabidopsis thaliana or Solanum lycopersicum as well as an artificial diet. After four generations, the microbial composition of the insect gut was evaluated to determine if the diet influenced the structure and function of the microbial communities. The population fed with A. thaliana had higher proportions of Shinella, Terribacillus and Propionibacterium, and these genera are known to have tolerance to glucosinolate activity, which is produced by A. thaliana to deter insects. The population fed with S. lycopersicum expressed increased relative abundances of the Agrobacterium and Rhizobium genera. These microbial members can degrade alkaloids, which are produced by S. lycopersicum. All five of these genera were also present in the respective leaves of either A. thaliana or S. lycopersicum, suggesting that these microbes are acquired by the insects from the diet itself. This study describes a potential mechanism used by generalist insects to become habituated to their available diet based on acquisition of phytochemical degrading gut bacteria.
