Summary

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.
