Erbsenwickler (Cydia nigricana) in Gemüse- und Körnererbsen: Grundlagen zur Befallsprognose und Schadensprävention

Summary in the original language of the document

Spatio-temporal distribution, combined with aspects of insect biology and ecology can influence the infestation risk of the key pea pest Cydia nigricana in vegetable- and
field peas. The proximity of pea fields of the previous cultivation period highly affects the infestation potential of the moth. The presented study aims to monitor the
infestation development in three different regions in Germany (North Hesse, Saxony, Saxony-Anhalt) in four consecutive years and to relate empirical pest incidences to
key factors as crop abundance, the distance to previous pea fields, the pea plant phenology and climatic conditions. In a next step, these data will form the basis for the
elaboration of a computer-aided decision support system, which assists farmers in implementing preventive strategies based on risk avoidance.
