Insecticide resistance is often linked to the expression of detoxification genes such as MDRs which code for ATP-binding cassette efflux transporters with broad substrate specificity. To investigate the role of MDR genes in Leptinotarsa decemlineata and Trichoplusia ni tolerance for the insecticide ivermectin, ingested dsRNA was used to attempt silencing of various MDR genes in these insects through RNA interference. Silencing was effective in L. decemlineata, but not T. ni. No change in ivermectin tolerance was found in L. decemlineata after MDR gene silencing. Because RNAi efficiency was different between L. decemlineata and T. ni, the stability …

Background: ABC transporter superfamily is one of the largest and ubiquitous groups of proteins. Because of their role in detoxification, insect ABC transporters have gained more attention in recent years. In this study, we annotated ABC transporters from a newly sequenced sweetpotato whitefly genome. Bemisia tabaci Q biotype is an emerging global invasive species that has caused extensive damages to field crops as well as ornamental plants.
Results: A total of 55 ABC transporters containing all eight described subfamilies (A to H) were identified in the B. tabaci Q genome, including 8 ABCAs, 3 ABCBs, 6 ABCCs, 2 ABCDs, 1 …
