Onion thrips are the insect vector of a severe virus in onion, Iris yellow spot virus. The thrips and virus are primary threats to the economic stability of onion production worldwide. Overuse of insecticides to suppress onion thrips has resulted in the development of resistance, reduced performance of insecticides, and reduced onion yields.
There is a compelling desire to find alternatives to better manage these pests. In this study, we assessed onion thrips populations on onions with low and high nitrogen rates, and near and far from corn and wheat, two common neighboring crops in the onion farm-scape.
