Electronic Thesis and Dissertation Repository
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 …
