The shelterbelt strategy to fight insect pests of fruit crops

Picture copyright DOMINGUEZ et al.

Damage on fruit production depends on the nature and movement of insects. However little is known on the year-round movements of insect predators in fruit crops and surrounding non-crop vegetation such as cover crops and edge plants. Agronomists Sorribas et al. showed that insect biodiversity was highest in organic managed farms. Nonetheless, insect abundance was highest in integrated pest managed systems. Numerous insect species moved from the crop toward edge shelterbelts to overwinter, because shelterbelts were largely preferred over cover crops. As a consequence, control strategies should focus on enhancing flying predators in shelterbelts.
