| Ziel des Projektes war die Erarbeitung eines Verfahrens zur Regulierung der Blutlaus (Eriosoma lanigerum), eines wirtschaftlich bedeutenden Schädlings im ökologischen Obstbau, gegen den es momentan keinerlei wirksame Bekämpfungsmöglichkeiten gibt. Hierzu wurde versucht, aus der Erfahrung vorangegangener Versuchsergebnisse ein Verfahren zur Bekämpfung der Blutlaus durch den Einsatz von Blutlauszehrwespen (Aphelinus mali) aus einer Nützlingszucht zu entwickeln und zur Praxisreife zu bringen. Die Zehrwespe ist ein natürlich vorkommender Gegenspieler, dem es aufgrund mangelnder Synchronisation zwischen Schädling und Nützling nicht rechtzeitig gelingt, den Schaden durch die Blutlaus zu verhindern. 2004 konnten mit dem Einsatz von parasitierten Blutlausmumien... |

| The release of Aphelinus mali HALD. from artificial rearing for the control of Woolly Apple Aphid (Eriosoma lanigerum HAUSM.) was tested in field trials. The release of adults proved to be more suitable than the release of cards with parasitized mummies as practised in the first trial. Setting free adult A. mali at the beginning of June reduced the aphid population, though its efficiency was not high enough to prevent damage of the trees totally. The practical applications of A. mali in early spring (after blossom) were not effective because climatic conditions were not suitable enough. The fertility of A. mali depends on temperature and light intensity. The application of Micula (rape oil) and T-S forte reduced the growth of the aphid population... |
