Summary in the original language of the document

The infestation of peas by aphids and moths was assessed in winter pea sole crops and compared to spring pea sole and winter pea-triticale intercrops. The field experiments were conducted in Northern Germany in the growing seasons 2009-2011. The maximum number of pea aphids per plant and the percentage of attacked plants were lower in semi-leafless and normal-leafed winter pea sole crops than in semi-leafless spring peas. Pea moth larvae damaged 6-32 % of seeds in winter peas and 40-55 % of seeds in spring peas. Winter pea-triticale intercropping reduced the attack of pea aphids, whereas no beneficial effect of intercropping was observed concerning moth-damaged peas. Owing to the earlier maturity, winter peas were less susceptible to pea pest attacks than spring peas. Winter-pea intercropping is a partially effective method for pest control in peas.
