Alternative Methoden zur Bekämpfung von Museumsschädlingen mit inerten Gasen am Beispiel der KleidermotteTineola bisselliella (Hum.)

Abstract

Many products like wool, fur and bird feathers are attacked by the common cloth mothTineola bisselliella (Hum.). The pest damages various materials and causes thereby high economic losses in warehouses, museums and also still in households. Until present, the effective control requires high amounts of chemicals. Especially in museums, high amounts are used despite possible health risk.

The development of the alternative pest treatment with carbon dioxide or nitrogen is meanwhile very successful in stored product pest control. The present study transfers this method to textile pest control. Because of the higher susceptibility of moth species without pronounced diapause, the lethal exposure period will presumably be shorter than for many other insect species. Of special importance for exhibits in museums and other valuable objects is the fumigation with pure nitrogen as very recommendable method for disinfestation without the risks of damaging the objects.

Zusammenfassung

Die Entwicklung der alternativen Bekämpfung von Vorrats-und Materialschädlingen mit Kohlendioxid und Stickstoff hat in den vergangenen Jahren große Fortschritte gemacht. In der vorliegenden Studie wurden diese Gase gegen die KleidermotteT. bisselliella angewandt und dabei beste Ergebnisse erzielt. Diese Ergebnisse werden näher betrachtet.
