Abstract

A repository block of ornamental crabapples containing 87 cultivars was left unsprayed and evaluated for resistance to the codling moth, <i>Laspeyresia pomonella</i> (L.). Although there were considerable differences in susceptibility, none of the cultivars was resistant to codling moth attack. A number of trees escaped injury from the first generation, but all showed entries from the second generation in August.
