A total of 1,338 genes were differently expressed in the thiamethoxam-resistant whiteflies. Overall design: All the B biotype whiteflies were maintained on cabbage. The susceptible strain (TH-S) was cultured without exposure to any chemical insecticides. Before the sample collected, almost 10,000 thiamethoxam-resistant adult whiteflies were treated with 2,000 mg/L thiamethoxam (~LC80) to eliminate the heterozygous individuals. Then the survivors were collected after 48 hours and designated as the TH-2000 sample. Then approximately 1,500 adult TH-S and TH-2000 were collected, respectively, The RNA was extracted and sequenced using Illumina HiSeq 2000.
