| Abstract:
Hazelnut weevil (Curculio nucum) is the most widespread pest in Tarragona (north-eastearn of Spain). Since the introduction of organic insecticides, the uncontrolled and indiscriminated fight with chemicals has led to the outcome of new pests, produced both by insects and mites. Some have become widespread pests (aphids, yellow spider, bud mite) and some a more localised (tortrix moth, scale, leopard moth). In recent years, the Integrated Pest Management System (IPM) has managed to keep most of these pests under control. Nevertheless, new problems are rising (rotting and a white spot on the fruits) which make new studies necessary. | |
