Expression profiles of ABC transporters throughout B. tabaci Q life cycle. The codes on the left are the gene ID numbers of the 55 ABC transporters in B. tabaci Q. The mRNA levels, as represented by log₂ (RPKM + 1) values, are shown in the gradient heat map with colors ranging from blue (low expression) to yellow (high expression). For each stage, values are normalized data from three biological replicates. E, egg; N1-2, 1^st- and 2^nd-instar nymphs; N3, 3^rd-instar nymph; N4, 4^th-instar nymph; F, adult female; M, adult male
