These data were collected by Dr. Anna Zelaya at Emory University in Fall 2021. Beetles were reared on black-eyed peas (N=32) or adzuki beans (N=31). Data set also includes a negative control (N=1). Beetles were from 4 different generations, 0, 2, 4 and 6 with 7 or 8 samples per generation per bean type. Beetles were from the LB strain adapted to their host bean for many generations. Beetles were females. Beetles were adults. Beetles were surface-sterilized. Beetles were extracted with QIAGEN DNA-Easy kits. Sequences are for the v4 region. MiSeq sequencing was done by MrDNA labs.
