Yeast-like symbionts (YLS) are endosymbionts that promote the growth of delphacid planthoppers (Hemiptera:
Delphacidae), some of which are pests on cultivated rice.Identification and characterization of YLS growth can be
helpful for pest control, because it has been demonstrated that there is a variety of YLS in rice planthopper and they
affected the planthopper’s growth and virulence to plant hosts.elucidation of the species of YLS in planthopper is
crucial for exploiting a new way to control planthopper
