in 19. Century led the Rebschädling in the European viticulture to dramatic devastations, the Reblauskatastrophe. The sheet louse originating from North America - used became in the middle 19. Century to France brought in (off approx. 1860 proven) and spread in the Reblausinvasion rapidly from there over all European Weinbaugebiete . The French government brought 1870 a commission for the fight of the Reblaus under presidency Louis Pasteurs into being, which examined allegedly over 700 suggestions and remained nevertheless unsuccessful.

for Schädlingsbekämpfung was bepfropft reblaustolerante common grape vines (being subject vines “ of the kinds Vitis riparia and Vitis berlandieri) from America with native Edelreisern (Vitis vinifera), then the complicated reproduction cycle could be interrupted.

In the yield viticulture there are world-wide only few root-genuine (ungepfropfte) situations. Sandy soils have the advantage that the Reblaus cannot hold itself here. Therefore such wine gardens remained as only spared, for example in the viticulture of Hungary during the Reblaus disaster.

life cycle

the life cycle of the Reblaus is complicated. Both purely underground living Wurzelrebläuse and aboveground Blattrebläuse arise. The Reblaus drills the roots of the Rebstöcke, it forms for rampant growths (Nodositäten so mentioned), of which the Reblaus nourishes itself sucking. The damage by secondary infections with bacteria and mushrooms shows up by reduced growth, fruit and wood yield, the wood-ripe retards.
