Whitefly Bemisia tabaci(Hemiptera: Aleyrodidae) is a destructive insect pest of many crops. Rickettsiainfection in different cryptic species of B. tabacihas been observed worldwide. Understanding the interactions between these 2 organisms is critical to developing Rickettsia-based strategies to control B. tabaciand thereby reduce the transmission of related vector-borne viruses. In this study, we investigated the effects of Rickettsiainfection on the biological characteristics of the Middle East Asia Minor 1 (MEAM1) strain of B. tabacithrough biological analysis of infected and uninfected individuals. The results of this study suggest that Rickettsiamay confer fitness benefits. These benefits include increased fertility, improved survival rates, accelerated development, and resulted in female bias. We also investigated the transcriptomics impact of Rickettsiainfection on B. tabaciby performing a comparative RNA-seq analysis of nymphs and adult females, both with and without the infection. Our analysis revealed 218 significant differentially expressed genes (DEGs) in infected nymphs compared to uninfected ones and 748 significant DEGs in infected female adults compared to their uninfected whiteflies. Pathway analysis further revealed that Rickettsiacan affect many important metabolic pathways in whiteflies. The results suggest that Rickettsiaplays an essential role in energy metabolism, and nutrient synthesis in the B. tabaciMEAM1, and depends on metabolites obtained from the host to ensure its survival. Overall, our findings suggest that Rickettsiahas beneficial effects on B. tabaciand offered insights into the potential molecular mechanisms governing the interactions between Rickettsiaand B. tabaciMEAM1. |
