Versuch zur Regulierung der Blutlaus mittels Ohrwurmansiedlung

Abstract

In years of disadvantageous atmospheric conditions natural control of woolly aphid by its parasite A. mali is insufficient in the majority of cases. In organic fruit-growing a chemical control is not possible. Settlements of earwigs showed a complete and lasting control of the pest in the year of testing, 2005. Fruit-damages were not found
