Plant viruses in agricultural crops are of great concern worldwide， and over 75% of them are transmitted from infected to healthy plants by insect vectors. Tomato yellow leaf curl virus (TYLCV) is a begomovirus， which is the largest and most economically important group of plant viruses， transmitted by the whitefly Bemisia tabaci. The circulation of TYLCV in the insect involves complex insect-virus interactions， whereas the molecular mechanisms of these interactions remain ambiguous. The insect gut as a barrier for viral entry and dissemination is thought to regulate the vector specificity. However， due to its tiny size， information for the responses of whitefly gut to virus infection is limited.
