The gut microbiota composition of Trichoplusia ni is altered by diet and may influence its polyphagous behavior

Abstract 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 compositio...
