Abstract
In most pome fruit growing areas, the codling moth (Cydia pomonella) is the major pest. In warm climates, the insect has 2 or more generations per year. Notwithstanding intensive spray schedules, in organic farming codling moth control is challenging due to the limited number of products available, and sometimes organic pome fruit growing becomes almost impossible due to high yield losses. An additional tool for suppressing codling moth consists in enclosing trees with net. In 2008 and 2009, different netting structures were compared at the Research Centre VZ-Laimburg, Auer, Italy. Promising results were obtained especially with single-row netting structures, which gave efficacy values in reducing codling moth damage of almost 100 %. Pome fruit growers in Northern Italy showed great interest in these trials.
