However, the relationship between gut microflora and host adaption of <i>T. absoluta</i> remains to be known. In this study, we first compared the survival adaptability of <i>T. absoluta</i> feeding with two host plants (tomatoes and potatoes). The <i>T. absoluta</i> completed the generation cycle by feeding on the leaves of both plants. However, the larvae feeding on tomato leaves have shorter larvae durations, longer adult durations, and a greater number of egg production per female.
